"DES stands for Data Encryption Standard. It is a symmetric-key block cipher algorithm used to encrypt and decrypt data. It is developed by the IBM team in early 1970. It accepts the plaintext in 64-bit blocks and changes it into the ciphertext that uses the 64-bit keys to encrypt the data. The algorithm uses … See more The algorithm performs 16 rounds of encryption and for each round, a unique key is generated. Before moving to the steps, it is important to know that in plaintext the bits are labeled from 1 to 64 where 1 is the most … See more The algorithm includes the following steps: 1. The algorithm takes the 64-bit plain text as input. 2. The text is parsed into a function called the Initial Permutation (IP) function. 3. The initial permutation (IP) function breaks the … See more There are the following five modes of operation that can be chosen: 1. ECB (Electronic Codebook):Each 64-bit block is encrypted and decrypted independently. 2. CBC (Cipher Block Chaining):In block chaining, each block … See more For decryption of the ciphertext, we use the same algorithm but in reverse order (step 4) of 16 round keys. For better understanding of the algorithm, let's see modes of operation for the DES algorithm. See more " - Des java program
