WebApr 12, 2024 · Using a data encryption algorithm, data encryption translates data from its raw, plain text form (plaintext data) — which is easily readable by anyone who accesses it — to a complex form or code (ciphertext) that's unreadable and unusable unless the user has a decryption key or password that will "decrypt" the data by translating it back to ... 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:
