- App-layer AES-256-GCM crypto helper (src/utils/crypto.js)
- Nextcloud tokens encrypted at rest; transparent migration on next use
- Audio backups encrypted at rest (version byte 0x01 envelope); legacy
rows still decrypt as-is until overwritten
- argon2id password hashing via src/utils/passwords.js with bcrypt
fallback; bcrypt hashes rehashed to argon2id on next successful login.
argon2 package is optional — server keeps running with bcrypt only
until npm install adds the native dep
- PHI redactor for audit log details (src/utils/redact.js) — strips SSN,
phone, email, DoB, long IDs; caps at 500 chars; detects note bodies
- DOMPurify (cdnjs, SRI-pinned) replaces custom regex sanitizer in
Learning Hub content rendering
- SRI integrity hashes added for Font Awesome CSS and Chart.js
- Magic-byte file-type verification on document uploads
(src/utils/fileType.js)
- Generic 500 error responses via src/utils/errors.js applied to
nextcloud and audioBackups; full detail still logged server-side
- DATA_ENCRYPTION_KEY env documented in .env.example
Deploy: requires rebuild of the container image to pick up the new
files and `npm install` (adds argon2). Existing users keep working
because bcrypt stays available and crypto helpers pass through
plaintext when the key is not yet set in dev.
Loki logs now include:
- User agent string (browser/device identification)
- Session ID (ties actions to specific login session)
- Status field (success/failure)
New logging:
- encounter_load: logged when user opens a saved encounter (with label)
- copy_to_clipboard: logged when user copies note content (PHI access)
- Client event endpoint: POST /api/logs/client-event (auth required)
Encounter save/delete/load all include the encounter label for
patient identification in audit trail.
HIPAA audit trail now covers: who, what, when, from where, which
device, which session, what patient data, success/failure.
