}Expand description
Block cipher mode of operation.
Block modes govern how a block cipher processes data spanning multiple blocks.
Required Methods§
sourcefn block_size(&self) -> usize
fn block_size(&self) -> usize
Block size of the underlying cipher in bytes.
sourcefn encrypt(&mut self, iv: &mut [u8], dst: &mut [u8], src: &[u8]) -> Result<()>
fn encrypt(&mut self, iv: &mut [u8], dst: &mut [u8], src: &[u8]) -> Result<()>
Encrypt a single block src using the initialization vector
iv to a ciphertext block dst.
Both iv and dst are updated. The buffer iv, dst and
src are expected to be at least as large as the block size
of the underlying cipher.
sourcefn decrypt(&mut self, iv: &mut [u8], dst: &mut [u8], src: &[u8]) -> Result<()>
fn decrypt(&mut self, iv: &mut [u8], dst: &mut [u8], src: &[u8]) -> Result<()>
Decrypt a single ciphertext block src using the
initialization vector iv to a plaintext block dst.
Both iv and dst are updated. The buffer iv, dst and
src are expected to be at least as large as the block size
of the underlying cipher.
