Trait for symmetric encryption ciphers.

Implementors provide authenticated encryption with associated data (AEAD).

Required Methods

fn encrypt( &self, plaintext: &[u8], associated_data: Option<&[u8]>, ) -> CryptoResult<Vec<u8>>

Encrypt plaintext with optional associated data.

Returns the ciphertext with embedded nonce and authentication tag.

fn decrypt( &self, ciphertext: &[u8], associated_data: Option<&[u8]>, ) -> CryptoResult<Vec<u8>>

Decrypt ciphertext with optional associated data.

The ciphertext must include the nonce and authentication tag.

fn algorithm(&self) -> &'static str

Get the cipher algorithm name.

fn key_size(&self) -> usize

Get the key size in bytes.

fn nonce_size(&self) -> usize

Get the nonce size in bytes.

fn tag_size(&self) -> usize

Get the authentication tag size in bytes.
