Secure. Offline. Zero-Knowledge.
CryptVault is a military-grade text encryption tool designed for absolute privacy. It runs entirely on your device using the Web Crypto API. No servers. No cloud. No tracking.
CryptVault is built on the principle that privacy is a human right.
- Offline First: The code executes locally in your browser or on your Android device.
- Audit Ready: Open-source architecture allows for full transparency.
- Standards Compliant: Utilizes native AES-256-GCM and PBKDF2 key derivation (250,000 iterations).
| Protocol | Security Level | Use Case |
|---|---|---|
| AES-GCM | HIGH (Recommended) | Authenticated encryption. Detects tampering. |
| AES-CBC | HIGH | Standard block cipher chaining. Robust compatibility. |
| AES-CTR | MEDIUM | Counter mode. High speed for large datasets. |
| Triple Layer | MAXIMUM | Base64 encoding wrapped in AES-GCM wrapped in Base64. |
| Simple | LOW | Deterministic. Identical input yields identical output. |
CryptVault is 100% free, open-source, and ad-free. If you value privacy tools, consider supporting the continued development.
