Detailed Description

Cryptographic block cipher.

Todo
Change encode(), decode() interfaces to allow passing the current block, because block selection with Bytes::select() is to expensive.

Constructor & Destructor Documentation

◆ BlockCipher() [1/2]

BlockCipher ( )
default

Create a null block cipher.

◆ BlockCipher() [2/2]

BlockCipher ( State * newState)
explicitprotected

Initialize with newState.

Member Function Documentation

◆ blockSize()

int blockSize ( ) const

Block size in bytes (required for encode() and decode())

◆ encode()

void encode ( const Bytes & p,
Out< Bytes > c )

Encipher plaintext block p into ciphertext block c.

Note
Both the plaintext block and the ciphertext block must have the proper block size.

◆ decode()

void decode ( const Bytes & c,
Out< Bytes > p )

Decipher ciphertext block c into plaintext block p.

Note
Both the plaintext block and the ciphertext block must have the proper block size.
