Description: DES uses a 56-bit key and an additional 8-bit parity bit, resulting in the largest 64-bit packet size. This is an iterative block cipher, using the technology known as the Feistel, which will encrypt the text block half. The use of sub-key pair, half of which application circulatory function, and then the output with the other half to " exclusive or" operator followed by the exchange of the two and a half, this process will continue, but in the end a cycle of non-exchange. DES uses 16 cycles.
