Encryption Toolkit

Encryption/decryption uses AES-256-GCM with a PBKDF2-derived key, entirely in your browser via the Web Crypto API. Your passphrase and plaintext are never sent to our servers — and there's no way to recover data if you lose the passphrase, since we never see it.

Enter a passphrase and plaintext, then click Encrypt.

Enter a passphrase and ciphertext, then click Decrypt.
