Block Cipher Base Class
interface BlockCipher: botan.algo_base.sym_algo.SymmetricAlgorithm;
This class represents a block cipher object.
abstract const size_t blockSize();
- Returns
- block size of this algorithm
abstract const @property size_t parallelism();
- Returns
- native parallelism of this cipher in blocks
final const size_t parallelBytes();
- Returns
- prefererred parallelism of this cipher in bytes
final void encrypt(const(ubyte)* input, ubyte* output);
- Parameters
const(ubyte)* input The plaintext block to be encrypted as a ubyte array. ubyte* output The ubyte array designated to hold the encrypted block. - Notes:
- Both arguments must be of length blockSize().
Encrypt a block.
final void decrypt(const(ubyte)* input, ubyte* output);
- Parameters
const(ubyte)* input The ciphertext block to be decypted as a ubyte array. ubyte* output The ubyte array designated to hold the decrypted block. - Notes:
- Both parameters must be of length blockSize().
Decrypt a block.
final void encrypt(ubyte* block);
- Parameters
ubyte* block the plaintext block to be encrypted - Notes:
