Web(“XOR” means “if one or the other, but not both.”) The XOR operation is reversible, such that if the encrypted information is run through the XOR comparison process again, the original text is revealed. Encryption … WebThe first reason is that DES was the first modern symmetric cipher. The second reason is that the general structure, often called a Feistel function or Feistel cipher, is still used in many modern algorithms. DES is a block cipher, which divides the plain text into 64-bit blocks and encrypts each block. The basic concept is as follows:
