#🎯 Key Findings

#Current System

Profiles stored in:
✓ MongoDB (development/localhost)
✓ localStorage (production)

Security:
✗ NO ENCRYPTION
✗ AWS keys visible in DevTools
✗ Database URLs exposed
✗ Plaintext JSON storage

#Proposed Solution

With Adapters:
✓ LocalEncryptedAdapter (IndexedDB + AES-256-GCM)
✓ DatabaseAdapter (MongoDB + optional encryption)
✓ SyncAdapter (automatic conflict resolution)

Security:
✓ AES-256-GCM encryption (military-grade)
✓ PBKDF2 key derivation (100k+ iterations)
✓ No plaintext credentials
✓ Works offline with automatic sync

#🎯 4 Decisions Needed From You

Answer these 4 questions to start implementation:

#Decision 1: Encryption Key

How should encryption keys be created?

A) Automatic (browser fingerprint)
B) User passphrase
C) HYBRID (auto + allow override) ⭐

#Decision 2: Server Encryption

Should server also encrypt?

A) No (client-side only)
B) Yes (end-to-end encryption) ⭐
C) Decide later

#Decision 3: Sync Frequency

How often to sync profiles?

A) Manual only
B) Automatic (every 30s)
C) HYBRID (auto + manual) ⭐

#Decision 4: Conflicts

When profile changes both places, which wins?

A) Server always
B) Local always
C) Merge by date ⭐
D) Manual UI choice

⭐ = Recommended choices

✅ Automatic sync (across devices)
✅ Conflict resolution (automatic or manual)
✅ Passphrase protection (optional)

#For Developers

✅ Adapter pattern (easy to extend)
✅ Clean architecture (separation of concerns)
✅ No breaking changes (API stays same)
✅ Full test coverage (templates provided)
✅ Security best practices (built-in)

#For Security

✅ AES-256-GCM (military-grade encryption)
✅ PBKDF2 key derivation (proven standard)
✅ No plaintext credentials (all encrypted)
✅ Auth tags (tampering detection)
✅ Security audit checklist (provided)

✅ Zero downtime migration (profiles auto-convert)

#🔐 Security Highlights

#Encryption

Algorithm: AES-256-GCM
Key Size: 256 bits (military-grade)
Authenticated: Yes (auth tags)
Mode: Galois/Counter Mode (proven)

#Key Derivation

Algorithm: PBKDF2-SHA256
Base: Passphrase or browser fingerprint
Iterations: 100,000+
Salt: 32 bytes random per user
Key Storage: NOT persisted (regenerated each session)

#Data Protection

At Rest: Encrypted in IndexedDB/localStorage
In Transit: HTTPS (same as current)
At Server: Optional server-side encryption
Authentication: Auth tag prevents tampering

#❓ FAQ

Q: When should we start?
A: Once you answer the 4 decisions, we can start Phase 1 immediately.

Q: How long will it take?
A: 2-3 weeks total (1-2 developers, including testing).

Q: Will it break existing profiles?
A: No - migration script handles automatic conversion.

Q: Can users still export profiles?
A: Yes - encrypted export feature will be added.

Q: Is it secure?
A: Yes - AES-256-GCM with PBKDF2 (military-grade).

Q: What about IE11?
A: Not supported by default (requires polyfills).

Q: Performance impact?
A: Minimal - encryption adds ~10-50ms per profile.

Q: Will API change?
A: No - endpoints unchanged (encryption is transparent).
