- 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.
