From e322145ffb74826c9ff66e856499e1b8fdca8018 Mon Sep 17 00:00:00 2001 From: goose Date: Sat, 18 Jul 2026 19:26:43 -0300 Subject: [PATCH 01/11] docs: decide multi-person ZK sharing ADR; reconcile jwt/encryption docs Rewrite the encryption/persona/JWT docs to match the implemented code and record the multi-person sharing design. - multi-person-sharing.md (NEW): ADR for per-profile DEK + X25519 envelope sharing. All five original open questions resolved 2026-07-18. Covers divorced-parents, pets, graduation, and elderly-parent care; adds an admin permission tier for owner-incapacity. Decided, not yet implemented. (#3) - encryption.md: full rewrite to the implemented wrapped-DEK / Web Crypto model; the old version described ZK encryption as 'planned'. (#4) - jwt-authentication-decision.md: rewritten to match implementation (PBKDF2 not bcrypt, no Redis, token_version revocation, real Claims). Original aspirational content preserved in a History section. (#4) - PERSONA_AND_FAMILY_MANAGEMENT.md: 'Current reality' section added, old 'Implementation Status' marked superseded, encryption section corrected. (#4) - ENCRYPTION_UPDATE_SUMMARY.md: archived (changelog for a rewrite that itself went stale).

Putting unenforced claims in the token + would imply protection that doesn't exist. + - `backend/src/auth/claims.rs` *does* define an `AccessClaims` struct with + `family_id`, `permissions`, `token_type`, `jti`. **It is dead code** — not + imported or used anywhere in the source (only in stale compiler scratch + files under `target/`).

Without it, two refresh + tokens issued in the same second for the same user would be byte-identical, + which breaks rotation and reuse detection. (Covered by the + `refresh_tokens_are_unique_even_in_same_second` test in `jwt.rs`.) +- On refresh: validate signature + expiry, confirm the token exists and is not + revoked in the repository, mint a new access + refresh pair, revoke the old + refresh token (rotation). -### Backend (Axum) -- jsonwebtoken 9.x (JWT crate) -- bcrypt 0.15 (password hashing) -- mongodb 3.0 (refresh token storage) -- redis (optional, for access token blacklist) +### Token revocation: versioning + session management -### Client (React Native + React) -- AsyncStorage (token storage) -- axios (API client with JWT interceptor) -- PBKDF2 (password derivation) -- AES-256-GCM (data encryption) +Two mechanisms, both implemented: ---- +1. **`token_version` (global kill-switch).** Stored on the `User` document, + incremented on password change and password recovery. The JWT middleware + (`middleware/auth.rs`) rejects any access token whose `token_version` is + stale against the user's current value. A short-lived `TokenVersionCache` + avoids hitting Mongo on every request. +2. **Session management.** Refresh tokens are tracked as sessions + (`GET /api/sessions`, `DELETE /api/sessions/:id`, `DELETE /api/sessions/all`) + so a user can list and revoke individual logins. -## Implementation Timeline +### Password handling -- **Week 1**: Basic JWT (login, register, middleware) -- **Week 1-2**: Refresh tokens (storage, rotation) -- **Week 2**: Token revocation (blacklist, versioning) -- **Week 2-3**: Password recovery (recovery phrases) -- **Week 3**: Family access control (permissions) -- **Week 3-4**: Security hardening (rate limiting, HTTPS) +- **PBKDF2** (not bcrypt — the original ADR mentioned bcrypt), via the `pbkdf2` + crate with a per-password random salt. (`backend/src/auth/password.rs`) +- Under the ZK model, what the server hashes is the **auth secret** — a + base64'd PBKDF2 derivation of the user's password produced client-side — not + the raw password. The raw password never leaves the browser. See + [`encryption.md`](../product/encryption.md) §2. -**Total**: 3-4 weeks +### Password recovery ---- +Recovery is handled by the **zero-knowledge wrapped-DEK** mechanism, *not* by +the "client encrypts the recovery phrase with the password" scheme the original +ADR described. The client derives a recovery KEK from the recovery phrase, +unwraps the DEK from the recovery-wrapped form, and re-wraps it under the new +password. See [`zero-knowledge-encryption.md`](./zero-knowledge-encryption.md) +§"Phase 2: Wrapped-DEK Recovery". The server bumps `token_version` on recovery, +invalidating all prior tokens. -## Next Steps +### What protects what -1. Implement basic JWT service in Axum -2. Create MongoDB schema for users and refresh tokens -3. Implement login/register/refresh/logout handlers -4. Create JWT middleware for protected routes -5. Implement token revocation (blacklist + versioning) -6. Integrate password recovery (from encryption.md) -7. Implement family access control (permissions) -8. Test entire authentication flow -9.

Per-session revocation is only available via the session + list (refresh-token deletion). +- HS256 with a shared secret means the secret is sensitive infrastructure; a + key rotation requires invalidating all tokens (acceptable for the deployment + model, but worth noting vs. asymmetric RS/ES keys). +- The dead `AccessClaims` struct is a latent trap — someone could wire it up + assuming `family_id`/`permissions` are enforced. Should be deleted. + +## Open items + +- **Remove `backend/src/auth/claims.rs`** (dead `AccessClaims`) or wire it up + intentionally. Tracked under issue #4. +- When issue #3 (multi-person sharing) is decided, revisit whether family / + share authorization belongs in the JWT or is enforced per-request against a + shares collection. + +## History (original 2026-02-14 decision, superseded where noted) + +The original ADR proposed: JWT with refresh tokens; bcrypt; optional Redis for +access-token blacklists; recovery by client-encrypting the recovery phrase with +the password; and `family_id`/`permissions` claims with parent/child/elderly +role matrices. Of these, only **JWT with refresh tokens + rotation** was built +as described. Password hashing uses PBKDF2 (not bcrypt), there is no Redis, +recovery uses the wrapped-DEK scheme (not phrase-encryption), and the family/ +permission claims were never wired into the real `Claims`.

The existing zero-knowledge model +(`zero-knowledge-encryption.md`) is single-user: **all of a user's data is +encrypted under one DEK that only that user can unwrap.** There is no mechanism +for a second user to decrypt any of it. As called out in issue #3, the current +`Share` model + `/api/shares` routes store ACL-style permission records but +cannot grant decryption access to another account — every medication blob is +under the owner's DEK, and the recipient has a different one. + +The product requirements that constrain this design (confirmed in issue #3): + +1. **Parents and spouses have separate logins**, and may belong to *different* + families. Divorced parents with their own families must be able to share the + profile of their common child **and nothing else**. +2. **Recipients always have Normogen accounts.** (One-way document dumps to + non-accounts — e.g. a physician via an encrypted PDF — is a separate, + simpler feature, out of scope here.) +3. **Revocation is a hard requirement.** Cutting off a caregiver must take + effect. +4. **The server operator is fully untrusted.** Key exchange cannot rely on the + server brokering symmetric secrets. + +Additional use cases from issue #3 that the model must accommodate: + +- **Profile graduation.** A child profile eventually becomes an independent + user with their own login, who may then revoke the parents' access. +- **Pets.** A profile may be an animal (medications, labs, etc.), not a human. + +## Decision + +Implement **per-profile DEKs with an X25519 asymmetric envelope** for sharing, +keeping the server a fully blind store. Concretely: + +### 1. Key hierarchy + +``` +password KEK ──wraps──▶ account DEK ──wraps each──▶ profile DEK ──encrypts──▶ profile data + │ (one per profile) + └──also wraps──▶ account X25519 private key + (account X25519 public key stored plaintext) +``` + +- **Account DEK**: random AES-256-GCM key, wrapped under the password KEK + (unchanged from today). At login the client unwraps it and holds it in + memory. +- **Profile DEK**: a *new* random AES-256-GCM key **per profile**. All data + belonging to a profile (its medications, appointments, etc.) is encrypted + under the profile DEK, not the account DEK. Each profile DEK is wrapped under + the account DEK and stored on the server, indexed by `profileId`. +- **Account X25519 keypair**: generated at registration. The **private** half + is wrapped under the account DEK (so it unlocks at login); the **public** + half is stored in plaintext — public keys are not secret. + +This adds one tier to today's flat `account DEK → data`. Rationale in +Consequences (§3-tier vs flat). + +### 2. Ownership and access + +- Each **profile** has exactly one **owning account** at a time. The owner + holds the profile DEK wrapped to their account DEK (the *owner share*). +- **Shared access** = the profile DEK wrapped to another account's X25519 + public key. Stored on the server as a *recipient share*, indexed by + `(profileId, recipientUserId)`. +- To **read** a shared profile, the recipient's client (at login) unwraps their + X25519 private key, ECDH-derives a wrapping key against the share's ephemeral + public key, and unwraps the profile DEK. + +This is the standard asymmetric-envelope pattern (cf. Signal, `age`, +Tarsnap). The server only ever stores wrapped blobs and public keys. + +### 3. Sharing flow (owner → recipient) + +Client-side only, server untrusted: + +1. Owner's client looks up the **recipient's X25519 public key** + (`GET /api/users/:id/public-key`, new). +2. Owner's client unwraps the target profile's DEK (via their account DEK). +3. Generate an **ephemeral X25519 keypair** for this share. +4. ECDH(ephemeral priv, recipient pub) → AES-GCM **wrapping key**. +5. Wrap the profile DEK under that wrapping key → `{ciphertext, iv, ephemeralPubKey}`. +6. `POST /api/profiles/:id/shares` with `{recipientUserId, wrappedDek, ephemeralPubKey, permissions, expiresAt?}`. +7. Server stores the share record. It cannot decrypt it. + +### 4. Revocation + +Two layers, in order of strength: + +- **Soft revoke** (cheap): delete or deactivate the recipient share record. The + recipient's client no longer receives the wrapped DEK from the server, so it + cannot decrypt **new reads**. Caveat: a malicious client that cached the + profile DEK before revocation keeps decrypting data it already fetched. +- **Hard revoke / re-key** (strong): owner generates a **new profile DEK**, + re-encrypts all of the profile's data under it, re-wraps to the owner share + and to all *still-valid* recipient shares. A revoked recipient's cached old + DEK now fails to decrypt any future fetch. Required for the "kid revokes + parent" graduation case where you must assume the parent may have cached + data. + +Hard revocation is the answer to requirement (3). Re-keying is expensive +(linear in profile data size) so it is opt-in / triggered explicitly, not the +default for every revoke. + +### 5. Profile model changes + +To support pets and graduation, the current `role: "patient"` string becomes: + +``` +kind: "human" | "pet" // distinguishes people from animals +relationship: string // freeform: "self", "child", "spouse", "pet", ... +``` + +Ownership-transfer (graduation) is **not new crypto** — it is the existing +share machinery plus an `owner_account_id` field swap: + +1. New adult account (the graduated child) generates its X25519 keypair. +2. Old owner wraps the profile DEK to the new account's pubkey as a share, and + marks that share as the new **owner share**. +3. Old owner's access is downgraded to (or removed as) a normal recipient share. +4. The new owner can revoke any remaining parent shares via soft/hard revoke. + +### 5b. Use case: elderly parent cared for by children + +A key motivation for the profile/account split is that **profile ownership and +account login are independent.** The elderly-care scenario has three setups, +all covered: + +- **Parent self-manages, shares to children.** Parent owns their own account + and `self` profile; creates recipient shares to each child. Standard + share-to-another-account flow. Any party can revoke. +- **Managing child holds a dedicated parent account.** A separate account + exists for the parent (the identity of record), but the managing child holds + or controls the password and shares the profile to siblings. Cleaner than + embedding the parent as a profile inside the child's account, and preserves + the "take over later" path: if the parent becomes able (or, conversely, + passes away), it's the same ownership machinery. +- **Parent modeled as a profile inside the managing child's account.** No + separate login for the parent; the child owns the profile and shares it. + Simplest, but the parent has no independent identity and cannot revoke + themselves. Recommend against this when the parent is or may become an + independent actor. + +**Death/incapacity of the sole-account owner** is the one wrinkle that needs +an explicit decision: see "Permissions and the admin-share question" below. + +### 5c. Permissions and the admin-share question + +The `permissions` list on a recipient share (Open question 3) raises a +sub-decision: **does an `admin` permission let a recipient act as a quasi-owner +without the original owner?** Specifically: re-share the profile, re-key it +(hard revoke), and add/remove other shares. + +This matters for two scenarios: + +- **Graduation in reverse / death of the owner.** If the parent owns the + account and becomes incapacitated, no child can write, re-share, or revoke — + those require the owner's account DEK, which is gone with the password. +- **Operational delegation.** A primary caregiver wants to delegate admin + tasks without sharing their password. + +**Decision: support an `admin` permission tier.** An admin share can re-share, +re-key, and manage other shares on a profile. This keeps the owner-DEK model +intact (the owner share is still special — it can *transfer* ownership, which +admin cannot) while handling the death/incapacity and delegation cases without +key escrow. Hard revocation (re-key) by an admin rotates the profile DEK and +re-wraps to all *still-valid* shares, same as owner-initiated re-key. + +> ❓ **Open sub-item:** when an admin re-keys, do we require a quorum or a +> second admin's consent? For MVP, no — any admin can act alone, matching how +> ownership transfer works today. Revisit if multi-party control becomes a +> requirement. + +### 6. What happens to the current `Share` model + +The existing `backend/src/models/share.rs` is **resource-level ACL** +(`resource_type`, `resource_id`, `permissions`) and predates encryption. It is +incompatible with this design, which shares at the **profile** level via keys, +not at the resource level via permissions. + +Per issue #3, profile-level sharing covers the family/caregiver need; the +"share one document" need is handled separately (physician PDF feature). So: + +- The current `Share` model and `/api/shares` routes are **retained for now** + but treated as a placeholder (issue #3). They will be either removed or + repurposed; this ADR does not depend on them. +- The new recipient-share records live in a **new collection** (provisional + name `profile_shares`) keyed by `(profileId, recipientUserId)`. Storing + wrapped DEKs, not ACLs. + +### 7. Server surface (new endpoints, indicative) + +- `GET /api/users/:id/public-key` → recipient's X25519 public key (plaintext). +- `GET /api/profiles/me/dek` → the account-wrapped profile DEK (owner unlock). +- `POST /api/profiles` → create profile: client generates profile DEK, wraps to + account DEK, sends wrapped form. Returns `profileId`. +- `GET /api/profiles/:id/shares` → list recipient shares for a profile. +- `POST /api/profiles/:id/shares` → create a recipient share (wrapped DEK). +- `DELETE /api/profiles/:id/shares/:shareId` → soft revoke. +- `POST /api/profiles/:id/rekey` → hard revoke / rotate the profile DEK. + +All endpoints store/return opaque blobs or public keys; none expose a DEK or a +private key. + +--- + +## Consequences + +### Positive + +- **Satisfies all four product constraints.** Per-profile keys enable the + divorced-parents case; hard revoke enables the revocation requirement; the + X25519 envelope keeps the server untrusted. +- **Profiles become first-class subjects of care** — owners, shares, pets, + graduation all fall out naturally. +- **Server stays a blind store.** No new backend crypto; still no `aes`/crypto + crates in `Cargo.toml`. +- **Composition with existing recovery.** The account DEK is still recovered + via the existing password/recovery wrapped-DEK flow; profile DEKs are wrapped + to the account DEK, so recovering the account recovers all profiles. + +### Negative / costs + +- **Adds a key tier.** Three levels instead of one. Complexity in the client + crypto module (`crypto/keys.ts` will grow X25519 + wrap-to-recipient logic). +- **Migration.** Today all data is under one account DEK. Splitting into + per-profile DEKs requires reading, decrypting, re-encrypting, and re-uploading + every document. **There is no real user data yet** (per + `zero-knowledge-encryption.md`), so this is cheap **now** and expensive + later — strong argument for doing the re-key before launch. +- **Hard revocation is expensive.** Re-keying a profile is O(profile data + size). Mitigation: soft revoke by default, hard revoke only when the owner + explicitly requires it (e.g. graduation, suspected compromise). +- **Recipient must have an account** (constraint 2). No magic-link sharing in + this design — deferred to the physician-PDF feature. + +### Security notes + +- **Ephemeral keys per share** prevent cross-share correlation and give + forward secrecy within a share's lifetime (re-keying rotates the DEK). +- **ECDH + AES-GCM** is the Web Crypto idiom; X25519 keys are 32 bytes, shares + are small. +- **Public keys are not authenticated by the server.** The owner must trust + that `GET /users/:id/public-key` returns the right key. Since the server is + untrusted, this is an accepted risk: a malicious server could swap the key + and force a re-share, but cannot decrypt. ❓ Decide whether to add a key + fingerprint the recipient verifies out-of-band. + +## Open questions (❓) — resolved 2026-07-18 + +1. **Key hierarchy depth.** ✅ **Decided: 3-tier** (account DEK → profile DEK → + data). Rationale: account DEK is recovered via the existing wrapped-DEK + recovery flow, so password change only re-wraps the account DEK (O(1)), + not every profile DEK. Profile DEKs are re-wrapped only on profile-level + events (share/revoke/rekey), which are rare. + +2. **Public-key trust.** ✅ **Decided: accept key-swap as DoS-only for now.** + A malicious server can swap a recipient's public key and force a failed + share (DoS) but cannot decrypt. **Future enhancement (not blocking):** add + a mechanism for out-of-band pubkey verification. Candidate approaches to + evaluate when we get there: + - **Key fingerprint / safety number.** Display a short hash of a user's + pubkey that two parties can compare out-of-band (cf. Signal safety + numbers). Cheap, requires user action. + - **Pubkey in recovery phrase / account export.** Derive or include the + pubkey fingerprint in something the user already verifies. + - **Web-of-trust / TOFU.** First-seen pubkey is pinned client-side; a change + triggers a user-visible warning. + These are additive — none changes the core envelope design, so they can + ship later without a migration. + +3. **Share record schema.** ✅ **Decided: `profile_shares` collection, schema + as proposed, permissions included.** Fields: + `{profileId, recipientUserId, ephemeralPubKey, wrappedDek, iv, permissions, + expiresAt, active, createdAt}`. `permissions` is a list (e.g. + `["read"]`, `["read","write"]`, `["read","write","admin"]`); the server + enforces write/admin server-side by checking the share record (the owner + always implicitly has admin via the owner share). See §"Permissions and + the admin-share question" below for the semantics of `admin`. + +4. **Migration.** ✅ **Decided: no migration — wipe the database.** There is + no real user data, and the re-key cost is unjustified. Phase A therefore + includes a clean-cutover step rather than a per-document migration. (This + also removes any legacy single-DEK documents that would otherwise need + special-casing.) + +5. **Existing `Share` model fate.** ✅ **Decided: remove entirely.** + `backend/src/models/share.rs`, the `/api/shares` routes, and the + `permissions/check` endpoint are deleted; the new `profile_shares` + collection and `/api/profiles/:id/shares` endpoints replace them. The + future per-resource physician-share feature will be built from scratch on + its own model when prioritized (it's a different access pattern — one-way + document dump, not ongoing profile access). + +## Phasing (proposal) + +- **Phase A — key tiers without sharing.** Introduce per-profile DEKs and the + account X25519 keypair; migrate existing data; no sharing endpoints yet. + Unblocks multi-profile-within-account (the parent/child single-login case). +- **Phase B — profile sharing.** The `POST/GET/DELETE /profiles/:id/shares` + endpoints and soft revoke. +- **Phase C — hard revoke / re-key.** The `/profiles/:id/rekey` endpoint and + owner-driven DEK rotation. +- **Phase D — graduation / ownership transfer.** Owner-share swap UI + endpoint. + +Each phase is independently shippable and independently testable. + +--- + +## References + +- Issue: [#3](https://gitea.soliverez.com.ar/alvaro/normogen/issues/3) +- Predecessor ADR: [`zero-knowledge-encryption.md`](./zero-knowledge-encryption.md) +- Current client crypto: `web/normogen-web/src/crypto/keys.ts`, `cipher.ts` +- Profile model: `backend/src/models/profile.rs` +- (Incompatible) current share model: `backend/src/models/share.rs` +- Web Crypto API: X25519 via `generateKey({name:"ECDH", namedCurve:"X25519"})`, + `deriveBits` for ECDH, `wrapKey`/`unwrapKey` or manual AES-GCM for the envelope. diff --git a/docs/product/ENCRYPTION_UPDATE_SUMMARY.md b/docs/archive/ENCRYPTION_UPDATE_SUMMARY.md similarity index 85% rename from docs/product/ENCRYPTION_UPDATE_SUMMARY.md rename to docs/archive/ENCRYPTION_UPDATE_SUMMARY.md index 2d745ea..68df3f4 100644 --- a/docs/product/ENCRYPTION_UPDATE_SUMMARY.md +++ b/docs/archive/ENCRYPTION_UPDATE_SUMMARY.md @@ -1,5 +1,13 @@ # Encryption.md Update Summary +> **ARCHIVED 2026-07-18.** This was a changelog note for a 2026-03-09 rewrite of +> `docs/product/encryption.md` that itself became stale (it describes ZK +> encryption as "planned" when it is in fact implemented).

Encryption Service Design +- Medication data blob — name, dosage, frequency, route, notes, etc. (the whole + record packed into one `encrypted_data` blob) +- Appointment data blob — title, provider, date/time, etc. +- Profile display name -```rust -use aes_gcm::{ - aead::{Aead, AeadCore, KeyInit, OsRng}, - Aes256Gcm, Nonce, -}; -use rand::RngCore; +### Plaintext (server-visible, queryable) -pub struct EncryptionService { - cipher: Aes256Gcm, -} +- IDs: `medicationId`, `appointmentId`, `userId`, `profileId` +- Medication `active` flag (for `GET /api/medications?active=true`) +- Appointment `status` +- `doseSchedule` (so the server can compute adherence from logged doses without + decrypting the medication record) +- Timestamps -impl EncryptionService { - /// Create new encryption service with key - pub fn new(key: &[u8; 32]) -> Self { - let cipher = Aes256Gcm::new(key.into()); - Self { cipher } - } +### Wire shape - /// Encrypt data - pub fn encrypt(&self, plaintext: &[u8]) -> Result, Error> { - let nonce = Aes256Gcm::generate_nonce(&mut OsRng); - let ciphertext = self.cipher.encrypt(&nonce, plaintext) - .map_err(|e| Error::Encryption(e.to_string()))?; - - // Return nonce + ciphertext - let mut result = nonce.to_vec(); - result.extend_from_slice(&ciphertext); - Ok(result) - } - - /// Decrypt data - pub fn decrypt(&self, data: &[u8]) -> Result, Error> { - if data.len() < 12 { - return Err(Error::Decryption("Invalid data length".to_string())); - } - - let (nonce, ciphertext) = data.split_at(12); - let nonce = Nonce::from_slice(nonce); - - self.cipher.decrypt(nonce, ciphertext) - .map_err(|e| Error::Decryption(e.to_string())) - } - - /// Derive key from password using PBKDF2 - pub fn derive_key_from_password( - password: &str, - salt: &[u8; 32], - ) -> [u8; 32] { - use pbkdf2::pbkdf2_hmac; - use sha2::Sha256; - - let mut key = [0u8; 32]; - pbkdf2_hmac::( - password.as_bytes(), - salt, - 100_000, // iterations - &mut key, - ); - key - } -} +``` +EncryptedField { data: base64, iv: base64, auth_tag: base64 } ``` -#### 2. Encrypted Health Data Model +For AES-256-GCM via Web Crypto the 12-byte IV is generated randomly per +encryption; the auth tag is appended to the ciphertext by `subtle.encrypt` and +validated on decrypt. -```rust -use serde::{Deserialize, Serialize}; -use mongodb::bson::Uuid; - -#[derive(Debug, Serialize, Deserialize)] -pub struct EncryptedHealthData { - pub id: Uuid, - pub user_id: Uuid, - pub data_type: String, // "medication", "lab_result", "stat" - - // Encrypted fields - pub encrypted_data: Vec, - pub nonce: Vec, // 12 bytes for AES-256-GCM - - // Searchable (deterministically encrypted) - pub encrypted_name_searchable: Vec, - - pub created_at: i64, - pub updated_at: i64, -} - -#[derive(Debug, Serialize, Deserialize)] -pub struct HealthData { - pub id: Uuid, - pub user_id: Uuid, - pub data_type: String, - pub name: String, - pub value: serde_json::Value, - pub created_at: i64, - pub updated_at: i64, -} -``` - -#### 3. Deterministic Encryption for Searchable Fields - -```rust -use aes_gcm::{ - aead::{Aead, KeyInit}, - Aes256Gcm, Nonce, -}; - -pub struct DeterministicEncryption { - cipher: Aes256Gcm, -} - -impl DeterministicEncryption { - /// Create deterministic encryption from key - /// Note: Uses same nonce for same input (less secure, but searchable) - pub fn new(key: &[u8; 32]) -> Self { - let cipher = Aes256Gcm::new(key.into()); - Self { cipher } - } - - /// Generate nonce from input data (deterministic) - fn generate_nonce_from_data(data: &[u8]) -> [u8; 12] { - use sha2::{Sha256, Digest}; - let hash = Sha256::digest(data); - let mut nonce = [0u8; 12]; - nonce.copy_from_slice(&hash[..12]); - nonce - } - - /// Encrypt deterministically (same input = same output) - pub fn encrypt(&self, data: &[u8]) -> Result, Error> { - let nonce_bytes = Self::generate_nonce_from_data(data); - let nonce = Nonce::from_slice(&nonce_bytes); - - self.cipher.encrypt(nonce, data) - .map_err(|e| Error::Encryption(e.to_string())) - } -} -``` +> Reference: `web/normogen-web/src/crypto/cipher.ts`, `backend/src/models/medication.rs` (`EncryptedFieldWire`). --- -## Key Management Strategy +## 5. In-memory key lifecycle (the ZK trade-off) -### Environment Variables +The DEK lives only in browser memory for the authenticated session. It is +**not persisted** to `localStorage`, `sessionStorage`, or a cookie. -```bash -# backend/.env -JWT_SECRET=your-256-bit-secret-key-here -MASTER_ENCRYPTION_KEY=your-256-bit-encryption-key-here -SHARE_LINK_MASTER_KEY=your-256-bit-share-key-here -``` +Consequence: **a page reload requires re-entering the password** to re-derive +the key (the "unlock" screen). This is intentional. Convenience features that +would weaken this (e.g. "remember me" that persists the DEK) are out of scope +unless separately designed. -### Key Derivation - -```rust -use sha2::{Sha256, Digest}; - -pub struct KeyManager { - master_key: [u8; 32], -} - -impl KeyManager { - pub fn new(master_key: [u8; 32]) -> Self { - Self { master_key } - } - - /// Derive unique key per user - pub fn derive_user_key(&self, user_id: &str) -> [u8; 32] { - let mut hasher = Sha256::new(); - hasher.update(format!("{}:{}", hex::encode(self.master_key), user_id)); - hasher.finalize().into() - } - - /// Derive key for specific document - pub fn derive_document_key(&self, user_id: &str, doc_id: &str) -> [u8; 32] { - let mut hasher = Sha256::new(); - hasher.update(format!( - "{}:{}:{}", - hex::encode(self.master_key), - user_id, - doc_id - )); - hasher.finalize().into() - } -} -``` +On logout / tab close, the key is cleared via `clearEncKey()`. --- -## Shareable Links with Embedded Passwords +## 6. What is NOT yet solved (see issues) -### Architecture Overview +### Multi-person / family / caregiver sharing — unsolved -``` -1. User has encrypted data in MongoDB -2. Creates a public share with a password -3. Generates a shareable link with encrypted password -4. External user clicks link → password extracted → data decrypted -``` +Sharing a medication with a spouse or caregiver requires the **recipient** to +be able to decrypt it, but everything is encrypted under the **owner's** DEK. +There is currently no key-distribution mechanism (no asymmetric envelope, no +re-wrapping to a recipient key). The `Share` model and `/api/shares` routes +exist but cannot actually grant decryption access to another user. -### Implementation Design +This is a design problem, not a bug, and it blocks the family/caregiver +personas. See **[issue #3](https://gitea.soliverez.com.ar/alvaro/normogen/issues/3)**. -```rust -use rand::RngCore; +### Multi-profile within one account — partial -#[derive(Debug, Serialize, Deserialize)] -pub struct ShareableLink { - pub share_id: String, - pub encrypted_password: String, // Embedded in URL - pub expires_at: Option, - pub max_access_count: Option, -} +`profileId` is plaintext and queryable, so medications can be tagged to +different people under one account.

Low priority until there's a reason. --- -## Password Recovery in Zero-Knowledge Systems +## 7. Backend security (complementary, server-side) -### Recovery with Zero-Knowledge Phrases +These are the server-side defenses that sit alongside (not instead of) the +client-side ZK encryption.

Each account now gets an X25519 keypair at registration: the public half stored plaintext, the private half wrapped under the account DEK and stored as opaque ciphertext. The keypair is generated client-side; the backend adds no crypto deps and stores everything verbatim, preserving the zero-knowledge contract. This change only introduces the keypair and threads it through the auth flows — it is not consumed yet. It unblocks Phase B (profile sharing) without touching the data model or the ~11 frontend encrypt call sites, which is Phase A2 (per-profile DEKs). Backend: - User model: identity_public_key, identity_private_key_wrapped{,_iv} (all Option, backward compatible). - RegisterRequest/AuthResponse carry the 3 fields; register + login echo them. No changes to change_password/recover (DEK value is unchanged across both, so the wrapped private key is too). - 2 new integration tests: round-trip through register/login, and optional-fields backward compat. Frontend: - crypto/keys.ts: generateIdentityKeyPair, wrapIdentityPrivateKey, unwrapIdentityPrivateKey + in-memory identity store mirroring the DEK. - types/api.ts: AuthTokens + RegisterRequest extended (removes an existing `as any` cast). - useStore register/login/logout + UnlockPage unwrap the private key alongside the DEK. - 3 new crypto tests (X25519 lifecycle, wrong-DEK rejection, distinct shared secrets); skip gracefully where the runtime lacks X25519. Backend: cargo test + clippy green. Frontend: npm test + tsc green.

All health data is now encrypted under the active profile's DEK, not the account-wide DEK. The account DEK wraps each profile DEK; the server stores only opaque wrapped blobs. Per the ADR: DB wipe, no migration (no real user data). This unblocks Phase B (sharing) — there is now a per-profile key to wrap to a recipient's X25519 public key. Backend: - Profile model: owner_account_id, kind (human/pet), relationship, wrapped_profile_dek + iv. ProfileRepository gains find_all_by_owner, find_by_profile_id_owned, update_profile, delete_profile — all ownership-scoped. - Profile handlers: GET/POST /api/profiles, GET/PUT/DELETE /api/profiles/:id. Removed /api/profiles/me. Renamed users.rs get_profile/update_profile (the /api/users/me handlers) to get_account/update_account to resolve a name collision. - Register accepts default_profile_* fields and auto-creates the self profile when the client provides a wrapped profile DEK. - HealthStatistic + Appointment gain profile_id and ?profile_id= filtering (health stats previously had no profile binding). - New profile_tests.rs: multi-profile CRUD + ownership isolation + register-with-default-profile. Fixed the zk health-stat test to send the now-required profile_id. Frontend: - crypto/keys.ts: generateProfileDek, wrapProfileDek, unwrapProfileDek + in-memory per-profile DEK store with an active-profile concept. - useProfileStore rewritten: holds profiles[], activeProfileId; loadProfiles unwraps each profile DEK; create/update/delete. All 11 encrypt/decrypt sites switched from getEncKey() to getActiveProfileDek(). load actions pass ?profile_id= so only the active profile's rows come back. - ProfileEditor rewritten for the new store (edit active profile, create/delete). New ProfileSwitcher in the Dashboard AppBar. - MedicationManager / AppointmentsManager use the active profile id instead of the hardcoded profile_. - 2 new crypto tests for per-profile DEK isolation; updated store + component tests for the active-profile-DEK model. Verification: backend cargo build/clippy/fmt green, tests compile (integration tests run in CI — Mongo is fixed there). Frontend tsc clean, 30/30 tests pass. Closes nothing yet (Phase B/C/D remain).

All three callers (login, change_password, recover_password) already match on Ok(true)/Ok(false)/Err and expect Ok(false) for a mismatch; the function just wasn't honoring that contract. Map Error::Password -> Ok(false) and propagate only genuine failures as Err. This was a latent bug: CI's auth tests never ran before because the Mongo service container couldn't schedule (port collision, fixed in #8). Now that CI runs them for real, login_with_wrong_password_is_rejected exposed it.

The server stays a blind store: sharing uses an X25519 envelope — the owner wraps the profile DEK to the recipient's identity public key via ECDH (fresh ephemeral key per share), the recipient unwraps it with their identity private key. Backend: - models/profile_share.rs: ProfileShare + ProfileShareRepository (find_for_recipient, find_for_profile, find_active [checks active + expiry], delete, upsert). Indexed on (profileId, recipientUserId) and recipientUserId. - handlers/profile_share.rs: POST/GET /profiles/:id/shares, DELETE /profiles/:id/shares/:recipient, GET /profiles/shared-with-me, GET /users/public-key (public), and authorize_profile_read — the share-gate that admits owner OR active-share recipient. - The share-gate is wired into list/get for medications, appointments, and health stats: when profile_id is specified, resolve the owner via the gate and query as them. Data repos stay ownership-scoped. - Removed the legacy Share system (ADR Open Q5): models/{share, permission}.rs, handlers/{shares,permissions}.rs, middleware/ permission.rs (dead), the shares collection field + methods in mongodb_impl.rs, the shares index, and the 5 /api/shares + /api/permissions routes. - share_tests.rs: full owner→recipient→revoke flow, ownership isolation, share-to-self/nonexistent/keyless rejections, expired share treated as absent. Frontend: - crypto/keys.ts: wrapProfileDekToRecipient / unwrapProfileDekFromShare (ECDH envelope, ephemeral key per share). - useProfileStore: loadSharedWithMe (unwrap each share's DEK with the identity private key), shareProfile, revokeShare, loadProfileShares. Shared profiles merge into the list with is_shared=true. - ProfileSwitcher: shows shared profiles with a 'shared' chip. - ProfileSharing (new) + ProfileEditor: owner UI to add a recipient by email and revoke; shared profiles render read-only with owner info. - ECDH round-trip test (owner wraps, recipient unwraps, stranger can't). Verification: backend cargo build/clippy (-D warnings)/fmt clean, tests compile (integration tests run in CI — Mongo is fixed there). Frontend tsc clean, 31/31 tests pass. ⚠️ Backend integration tests not run locally (no Mongo/Docker in this sandbox); CI will run them — I'll fix any failures immediately.

The query string was never formed, so the handler got an empty email. Fix: put ?email=... in the URI directly (URL-encoding the '@'). 2. public_key_lookup_404s_for_unknown_or_keyless_user — same root cause. 3. owner_shares_recipient_reads_owner_revokes — asserted the recipient's write would return 201 or 403, but create_medication returns 200 OK (Axum's default for Ok(Json(...))), and the write currently succeeds because the create handler doesn't check ownership (issue #12). The write is attributed to the recipient, not the owner, so the owner's data is still untouched — which is what the test really wants to prove.

CI caught this: zk_integration_tests::medication_stored_as_ciphertext_not_plaintext creates a medication with profile_id="default" (no Profile doc) and the new get_medication gate returned 404. Fix: in each list/get data handler, check direct ownership (user_id == claims.sub, or has own data for the profile) FIRST, and only fall through to the share-gate if the caller isn't the direct owner. This preserves the original ownership model AND adds share- recipient access, without breaking items whose profile_id isn't a real Profile document. The share-only path (recipient reading shared data they don't own) still goes through the gate as before. --- backend/src/handlers/appointments.rs | 27 ++++++++++++++----- backend/src/handlers/health_stats.rs | 30 ++++++++++++++++----- backend/src/handlers/medications.rs | 39 ++++++++++++++++++++++------ 3 files changed, 74 insertions(+), 22 deletions(-) diff --git a/backend/src/handlers/appointments.rs b/backend/src/handlers/appointments.rs index b4e3244..7939fc4 100644 --- a/backend/src/handlers/appointments.rs +++ b/backend/src/handlers/appointments.rs @@ -69,12 +69,22 @@ pub async fn list_appointments( let database = state.db.get_database(); let repo = AppointmentRepository::new(database.collection("appointments")); - // Share-gate: if a profile_id is specified, resolve the owner (admits the - // owner or an active share recipient) and query as them.

Same gap on log_dose (could skew another's adherence stats) and get_adherence (leaked dose history). Fix: each affected handler now looks up the item first and confirms user_id == claims.sub before mutating/returning. Mismatches return 404 (not 403) to avoid leaking the existence of other users' records. Recipients of shared profiles remain read-only per the ADR — writes stay owner-only. Covered handlers: - update_medication, delete_medication, log_dose, get_adherence - update_appointment, delete_appointment health_stats update/delete were already checking user_id == claims.sub (unaffected). New ownership_tests.rs: cross-user update/delete/log-dose/adherence all 404; the legitimate owner can still do all of the above. Verification: cargo build/clippy (-D warnings)/fmt clean; existing tests unaffected (they operate as the same user that created the data).

charset=UTF-8 Content-Transfer-Encoding: 8bit backend/src/auth/claims.rs was orphaned dead code: auth/mod.rs never declared 'mod claims', so the file wasn't compiled into the crate at all. It defined two structs: - AccessClaims — referenced nowhere; a latent trap (carried family_id/permissions fields that suggested enforcement that doesn't exist). - RefreshClaims — a duplicate of the LIVE RefreshClaims in jwt.rs, which is what JwtService actually uses. Deleted the file. Updated the JWT ADR to mark the open item done and note the removal historically. Build/clippy/fmt clean (the file wasn't compiled anyway).

From bf5aeedbc2cb522e92056c83cfa3698c1313b8ed Mon Sep 17 00:00:00 2001 From: goose Date: Sun, 19 Jul 2026 15:15:39 -0300 Subject: [PATCH 10/11] feat: hard revoke / re-key (Phase C, #3) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit An owner can now rotate a profile's DEK — generating a fresh key, re-encrypting all the profile's data under it (client-side), and re-wrapping to the owner share + kept recipients. A revoked recipient's cached old DEK stops working, closing the soft-revoke window the ADR requires for graduation / suspected compromise. The server stays a blind store: it sees opaque old→new ciphertext blobs flow through, never the DEK or plaintext. No backend crypto. Backend: - ProfileRepository::update_wrapped_dek — rotate the owner share (account-wrapped profile DEK), owner-scoped. - ProfileShareRepository::find_active_for_profile + delete_for_profile_excluding — list current recipients and hard-delete omitted ones. - POST /api/profiles/:id/rekey: validates each submitted envelope against existing active shares (no smuggling new recipients in via rekey), rotates the owner share, upserts recipient envelopes with fresh ephemeral ECDH keys, hard-deletes omitted recipients. - rekey_tests.rs: rotation, hard-revoke-from-recipient-view, no-share rejection, non-owner rejection, revoke-all. Frontend: - useProfileStore.rekeyProfile: fetches all profile data, re-encrypts each row under a new DEK (resume-safe — rows already on the new DEK are skipped), builds fresh ECDH envelopes per kept recipient, commits via POST /rekey, swaps the in-memory DEK. - ProfileSharing: 'Rotate encryption key (hard revoke)' action with a strong confirmation dialog explaining the cost and the resume-safe retry. Best-effort + resumable retry (per design decision); no server-side write lock. Verification: backend cargo build/clippy (-D warnings)/fmt clean, tests compile (integration tests run in CI — Mongo is fixed there). Frontend tsc clean, 31/31 tests pass. ⚠️ Backend integration tests not run locally (no Mongo in this sandbox); CI will run them — I'll fix any failures. Admin-initiated rekey (ADR §5c reserves the permission) is out of scope — handler is owner-only until admin shares are creatable in Phase D.

Fix: echo the request values (exactly what was stored) in the response instead of reading them back. Unambiguous and avoids the ReturnDocument::After plumbing. The write itself was always correct (the stored value was v2) — only the response was stale, which is why the other rekey tests (which check state via fresh reads, not the response body) passed.
