Des And 3des Вђ“ Azmath Direct

While 3DES fixed the security issues of its predecessor, it introduced a new problem: performance. Because it runs the DES algorithm three times, it is significantly slower than more modern ciphers. Furthermore, its 64-bit block size eventually became a liability against certain types of cryptanalysis (such as "Sweet32" attacks).

To address the vulnerabilities of DES without completely discarding its proven architecture, the industry introduced Triple DES (3DES). Instead of creating a new algorithm from scratch, 3DES applies the DES cipher three times to each data block. It typically uses three 56-bit keys (K1, K2, and K3) in an encrypt-decrypt-encrypt (EDE) sequence. DES and 3DES – AZMATH

Despite its architectural brilliance, DES had a fundamental flaw: its key length. A 56-bit key offers 2562 to the 56th power While 3DES fixed the security issues of its
