possible combinations. While this seemed insurmountable in the 1970s, the rapid advancement of computing power—often referred to as Moore’s Law—eventually made DES vulnerable to brute-force attacks. By the late 1990s, specialized hardware could crack a DES key in less than a day, rendering it obsolete for high-security applications.

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

The Evolution of Block Ciphers: From DES to 3DES In the realm of cryptography, the Data Encryption Standard (DES) and its successor, Triple DES (3DES), represent a pivotal chapter in the history of data security. Originally designed to protect sensitive but unclassified information, these algorithms laid the groundwork for modern encryption protocols. possible combinations
