💡 How it works

Key Derivation

Your password is stretched into a cryptographic key using PBKDF2 with 100,000 iterations and SHA-256. A random 16-byte salt is generated each time.

AES-GCM

Galois/Counter Mode provides authenticated encryption. Any modification to the ciphertext will be detected during decryption. A random 12-byte IV is used per encryption.

Output Format

The base64 output encodes: salt[16] + IV[12] + ciphertext. Share this string + the password to allow decryption on this page.
