Struct AegisCipher 

pub struct AegisCipher(/* private fields */);

AEGIS-256X2 cipher bound to a single (key, nonce) pair.

All operations consume self, making it a compile-time error to reuse the same (key, nonce) pair across two different calls.

See the module documentation for performance guidance and trade-offs versus ChaCha20Poly1305Cipher.

Implementations

impl AegisCipher

pub fn new(key: &[u8; 32], nonce: &[u8; 32]) -> Self

Initialises the cipher. The AEGIS key schedule runs here.

pub fn encrypt( self, aad: &[u8], plaintext: &[u8], ciphertext: &mut [u8], ) -> Result<(), Error>

Encrypts plaintext and writes ciphertext || tag into ciphertext. ciphertext must be at least plaintext.len() + TAG_LEN bytes long.

pub fn decrypt( self, aad: &[u8], ciphertext: &[u8], plaintext: &mut [u8], ) -> Result<(), Error>

Decrypts and verifies ciphertext, writing plaintext into plaintext.

ciphertext must end with a TAG_LEN-byte tag; plaintext must be at least ciphertext.len() - TAG_LEN bytes long.

On tag failure, plaintext is zeroed before returning Err.

Trait Implementations

impl Drop for AegisCipher

fn drop(&mut self)

Executes the destructor for this type.
