#include <cryptlib.h>
Inheritance diagram for BlockTransformation:
Classes derived from BlockTransformation are block ciphers in ECB mode (for example the DES::Encryption class), which are stateless, and they can make assumptions about the memory alignment of their inputs and outputs. These classes should not be used directly, but only in combination with a mode class (see CipherModeDocumentation in modes.h).
