DES (Data Encryption Standard) is a symmetric-key algorithm used for encrypting and decrypting data. When combined with hexadecimal (hex) encoding, DES encryption can be represented in a more readable format. The process involves encrypting plain text using the DES algorithm and converting the resulting cipher text into a hexadecimal string. This format is often used in secure data transmissions, cryptography tools, and data storage systems to ensure that the encrypted output is compact and easy...
