What Is DES Encryption?

DES (Data Encryption Standard) is a symmetric-key encryption algorithm used to secure digital data. It uses a 56-bit key to encrypt 64-bit data blocks through substitutions and permutations.

Although now less secure due to modern computing power, DES laid the foundation for advanced encryption standards. It is still useful for learning and supporting legacy systems.
