WebMar 14, 2024 · DES Decryption − It is an extremely complex encryption scheme and thus the decryption using DES can employ an ultimately different approach. The similar algorithm is used for encryption in DES also works for decryption. The values of the multiple tables and the operations as well as their sequence are so carefully selected that the … WebJul 29, 2024 · DES works by encrypting groups of 64 message bits, which is the same as 16 hexadecimal numbers. To do the encryption, DES uses “keys” where are also apparently 16 hexadecimal numbers long, or apparently 64 bits long. However, every 8th key bit is ignored in the DES algorithm, so that the effective key size is 56 bits. ...
