}

An authenticated cipher with associated data.

Required Associated Constants

const KEY_LEN: usize

Key length in bytes.

const NONCE_LEN: usize

Nonce length in bytes.

const TAG_LEN: usize

Authentication tag length in bytes.

Required Methods

fn new(key: &[u8]) -> Result<Self>

where Self: Sized,

Bind a key to a cipher instance.

fn seal_detached( &self, nonce: &[u8], aad: &[u8], in_out: &mut [u8], tag: &mut [u8], ) -> Result<()>

Encrypt in_out in place and write the tag to tag.

fn open_detached( &self, nonce: &[u8], aad: &[u8], in_out: &mut [u8], tag: &[u8], ) -> Result<()>

Verify tag and decrypt in_out in place.

On failure in_out is zeroized before returning, so a caller that ignores the error cannot expose unauthenticated plaintext.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
