Function sodiumoxide::crypto::aead::chacha20poly1305_ietf::seal_detached

pub fn seal_detached(m: &mut [u8], ad: Option<&[u8]>, n: &Nonce, k: &Key) -> Tag

seal_detached() encrypts and authenticates a message m together with optional plaintext data ad using a secret key k and a nonce n. m is encrypted in place, so after this function returns it will contain the ciphertext. The detached authentication tag is returned by value.
