WebJan 3, 2024 · DES is a complex algorithm that works by dividing an input text into smaller 64-bit blocks. Each block then goes through an initial permutation, and the result of the initial permutation is further divided into two parts called LPT and RPT. These two parts then go through the Feistel function for 16 rounds. WebThe basic difference between DES and AES is that the block in DES is divided into two halves before further processing whereas, in AES entire block is processed to obtain ciphertext.
