WebJul 4, 2024 · As we know the Data encryption standard (DES) uses 56 bit key to encrypt any plain text which can be easily be cracked by using modern technologies. To prevent this from happening double DES and triple DES were introduced which are much more secured than the original DES because it uses 112 and 168 bit keys respectively. 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.
