Common questions

Answers about Ascon Encryption

What key and nonce does this Ascon operation require?

The operation requires a 16-byte key and a 16-byte nonce. Choose the correct representation for each field before checking its length. A nonce is separate from the secret key.

Where is the Ascon authentication tag?

Encryption returns ciphertext with the authentication tag attached. Decryption expects that combined input and the same Associated Data. Changing the key, nonce, data, or tag can cause authentication failure.

Can I reuse one nonce for different Ascon messages?

Use a different nonce for each new encryption under the same key. The tool accepts your supplied nonce; completion does not check your previous usage. Keep the nonce and associated-data convention with the ciphertext.
