WebEncrypt the plaintext blocks using single DES with key K 1. Now decrypt the output of step 1 using single DES with key K 2. Finally, encrypt the output of step 2 using single DES with key K 3. The output of step 3 is the ciphertext. Decryption of a ciphertext is a … WebNov 11, 2024 · Although DES has a 64-bit block and key size, the key only provides 56 bits of protection in practise. Because of the short key length of DES, 3DES was created as a more secure alternative.The DES algorithm is executed three times with three keys in 3DES; nevertheless, it is only deemed secure if three distinct keys are utilised.
