Trait Implementations

impl Aead for TweakAead

fn encrypt( &self, key: &AeadKey, nonce: &Nonce, plaintext: &[u8], associated_data: Option<&[u8]>, ) -> Result<Vec<u8>>

Encrypt data

fn decrypt( &self, key: &AeadKey, nonce: &Nonce, ciphertext: &[u8], associated_data: Option<&[u8]>, ) -> Result<Vec<u8>>
