DES Algorithm Module

Data Encryption Standard (DES) Algorithm

The Data Encryption Standard (DES) is a symmetric-key block cipher published by the National Institute of Standards and Technology (NIST). DES is an implementation of a Feistel Cipher. It uses 16 round Feistel structure. The block size is 64-bit. Though, key length is 64-bit, DES has an effective key length of 56 bits, since 8 of the 64 bits of the key are not used by the encryption algorithm (function as check bits only).

Example Code

key = "12345678"
text = "Hello wo11"
print("Ciphered: ", encrypt(key, text))
print("Deciphered: ", decrypt(key, encrypt(key, text)))

Output

Ciphered:  #####
Deciphered:  Hello wo11
