Text Encryptor & Decryptor (AES)

AES-256-GCM text encryption

Runs locally using Web Crypto, PBKDF2-SHA256 (600,000 iterations), a random 16-byte salt and 12-byte nonce. Keep the complete output and passphrase; there is no recovery service.

An encrypted message is only as safe as its passphrase and the device handling it. Decryption rejects modified data and incorrect passphrases. Legacy XOR output is not compatible. Do not paste secrets into the separate AI assistant.
