I built a zero-knowledge security
Sushil C
I built a zero-knowledge security vault with Python, Flutter & AWS 🔐.This was a unique personal project!
Built a password vault from scratch.
Meet SecureFlow — a cross-platform security system for passwords, 2FA and sensitive documents.
AES-256-GCM.
HKDF-SHA256.
Encrypted S3 sync.
Biometrics + NFC.
TOTP.
The challenge? Making desktop and mobile cryptographically compatible while minimizing plaintext exposure.
From encryption to cloud sync to my shot at anomaly detection, this turned into a full security-focused product.
What security feature would you add?
