What encryption algorithm is used?
▼
AES-256-GCM — the gold standard for symmetric encryption. Keys are derived from your password using PBKDF2 with 100,000 iterations.
Is my password sent to any server?
▼
Absolutely not. Everything happens in your browser via the Web Crypto API. Your password and text never leave your device.
What if I forget my password?
▼
There is no password recovery. The encryption is real — without the exact password, the text cannot be decrypted.
Can I share encrypted text safely?
▼
Yes, copy the encrypted output and share it through any channel. Only someone with the password can decrypt it.
