Implementations

impl AeadImpl

pub fn from_header_and_key( header: &HeaderV1, session_key: &[u8], ) -> Result<Self, CryptoError>

Construct AEAD implementation from header.cipher and derived session key.

pub fn seal( &self, nonce_12: &[u8], aad: &[u8], plaintext: &[u8], ) -> Result<Vec<u8>, CryptoError>

AEAD seal (encrypt) plaintext with nonce and AAD.

pub fn open( &self, nonce_12: &[u8], aad: &[u8], ciphertext_and_tag: &[u8], ) -> Result<Vec<u8>, CryptoError>

AEAD open (decrypt) ciphertext with nonce and AAD.

pub fn seal_in_place( &self, nonce_12: &[u8], aad: &[u8], buf: &mut (dyn Buffer + 'static), ) -> Result<(), CryptoError>

AEAD seal (encrypt) plaintext in place with nonce and AAD. The buffer must have enough capacity for plaintext + tag.

pub fn open_in_place( &self, nonce_12: &[u8], aad: &[u8], buf: &mut (dyn Buffer + 'static), ) -> Result<(), CryptoError>

AEAD open (decrypt) ciphertext in place with nonce and AAD. The buffer must contain ciphertext+tag, will be replaced with plaintext.
