AES-256 CCM driver.

Required Associated Types

type Context: Send + Sync + Clone

Opaque storage for the implementation’s key schedule.

Required Methods

fn init(key: &[u8; 32]) -> Self::Context

Initialize with a 256-bit key.

fn encrypt( ctx: &Self::Context, nonce: &[u8], aad: &[u8], buffer: InOutBuf<'_, '_, u8>, tag: &mut [u8], ) -> Result<(), Error>

Encrypt buffer and produce the authentication tag.

The tag length is the length of the tag slice. Nonce and tag lengths not allowed by the spec return Error::InvalidInput.

fn decrypt( ctx: &Self::Context, nonce: &[u8], aad: &[u8], buffer: InOutBuf<'_, '_, u8>, tag: &[u8], ) -> Result<(), Error>

Verify the authentication tag and decrypt buffer.

The tag length is the length of the tag slice. Nonce and tag lengths not allowed by the spec return Error::InvalidInput. The tag is verified in constant time; on mismatch this returns Error::InvalidSignature and the buffer contents are unspecified.

Dyn Compatibility

This trait is not dyn compatible.

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