Encrypt anything. Quantum-resistant.
AES-256-GCM with a memory-hard PBKDF2-SHA256 (600k iterations) key. Symmetric AES-256 keeps ~128-bit strength even against a quantum adversary. Your passphrase and text are processed in memory only — never stored, never logged.

How it protects you
- Your passphrase is stretched with PBKDF2-SHA256 (600k iterations), then used as an AES-256-GCM key.
- Every ciphertext is authenticated — if a single byte is altered, decryption refuses (no silent tampering).
- Zero-knowledge: the server never stores your text or passphrase, and the operation is never logged.
- Symmetric AES-256 is the pragmatic post-quantum choice: Grover's algorithm only halves the key strength, leaving ~128-bit security.
