Des And 3des May 2026

Developed in the 1970s, DES was the global standard for decades before its 56-bit key became vulnerable to modern brute-force attacks.

Each of the 16 rounds involves expansion, XOR with a subkey, substitution (via S-boxes), and permutation. DES and 3DES

The inverse of the initial permutation to produce the final ciphertext. 2. Triple DES (3DES) Developed in the 1970s, DES was the global

3DES was introduced to extend the life of DES by applying the algorithm three times to each data block, significantly increasing the effective key length to combat brute-force attacks. Developed in the 1970s

Uses a Feistel network consisting of 16 rounds of processing.
