In cryptography, ciphertext or cyphertext is the result of encryption performed on plaintext using an algorithm, called a cipher. Ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it. 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: how many units is in 1 ml
