Des And 3des -

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

This guide covers the and its more secure successor, Triple DES (3DES) . Both are symmetric-key block ciphers that encrypt data in 64-bit blocks. 1. Data Encryption Standard (DES) DES and 3DES

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, DES was the global
