FAQ
Completely free, no registration required. Perform AES encryption and decryption directly in your browser — all operations run locally with no usage limits.
It uses AES-GCM mode with PBKDF2 key derivation to generate a 256-bit key from your password, meeting modern encryption security standards. Each encryption generates a random IV for security.
No. All encryption and decryption runs locally in your browser. Neither the password nor ciphertext is sent to any server. Keep your password safe — it cannot be recovered if lost.
AES-GCM provides both encryption and integrity verification (authenticated encryption), detecting if ciphertext has been tampered with. AES-CBC only provides encryption without integrity verification. GCM is more secure and preferred for modern applications.
