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 standard for decades before its 56-bit key became vulnerable to modern brute-force attacks. DES and 3DES

Uses a Feistel network consisting of 16 rounds of processing. 3DES was introduced to extend the life of

Rearranges the 64 bits of the input block. DES and 3DES
