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)
Uses a Feistel network consisting of 16 rounds of processing. DES and 3DES
The inverse of the initial permutation to produce the final ciphertext. 2. Triple DES (3DES) This guide covers the and its more secure
56-bit effective key length (plus 8 parity bits for a total of 64 bits). Block Size: 64 bits. Process Steps: 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.
