Block Cipher

A block cipher is a deterministic algorithm operating on fixed-length groups of bits called blocks. Crypto++ includes the following block ciphers:


For ECB and CBC mode, data must be processed in multiples of the block size.

Alternatively, the mode object can be wrapped StreamTransformationFilter for use as a Filter object. StreamTransformationFilter will take care of buffering data into blocks as required.
