The DES algorithm is a fixed-width encryption algorithm. Therefore, the input message is first padded to make sure that it will completely fit in “n” number of 64-bit blocks.

The Data Encryption Standard (DES) was a widespread symmetric key block cipher algorithm. It was the most popular used cryptographic scheme. DES's security was a highly contentious and controversial ...

To address issues in security & the threat posed to the DES algorithm by brute force cracking, as well as the low efficiency of the 3DES algorithm, I propose extending the length of the DES ...
