Overview#
In cryptography, a Block Cipher is a deterministic algorithm operating on fixed-length groups of bits, called Block, with an unvarying transformation that is specified by a Symmetric Key.Block Cipher are important Cryptographic Primitive components in the design of many cryptographic protocols, and are widely used to implement encryption of bulk data.
Block cipher mode of operation#
There are several different Block cipher mode of operation that are used.Block Cipher operate on large blocks of digits with a fixed, unvarying transformation. This distinction is not always clear-cut: in some modes of operation, a Block Cipher primitive is used in such a way that it acts effectively as a Stream Cipher.
