Expand description

Block cipher mode of operation.

Block modes govern how a block cipher processes data spanning multiple blocks.

Required methods

Block size of the underlying cipher in bytes.

Encrypt a single block src using the initialization vector iv to a ciphertext block dst.

Both iv and dstare updated. The bufferiv, dstandsrc` are expected to be at least as large as the block size of the underlying cipher.

Decrypt a single ciphertext block src using the initialization vector iv to a plaintext block dst.

Both iv and dstare updated. The bufferiv, dstandsrc` are expected to be at least as large as the block size of the underlying cipher.
