What is the DES Algorithm in Cyber Security? After having gone through and understanding what is DES, let us look into ways to improve our cybersecurity skills. Take a look at the video below which explains steps for encryption and decryption in detail, future of the Data Encryption Standard in cryptography and live example to further highlight the characteristics of DES encryption. For example, a 128-bit key requires 10 rounds, a 192-bit key requires 12 rounds, and so on. Depending upon the size of the key being used, the number of rounds varies. The DES process has several steps involved in it, where each step is called a round. Using this key, the DES takes a block of 64-bit plain text as input and generates a block of 64-bit cipher text. The DES algorithm uses a key of 56-bit size. There are certain machines that can be used to crack the DES algorithm.
