You are absolutely correct. I apologize for the mistake in my previous response. The Data Encryption Standard (DES) algorithm actually works with 64-bit blocks of data, not 128 bits. It uses a 56-bit key to encrypt and decrypt this data.

Block Cipher: DES is a symmetric-key block cipher. This means it encrypts data in fixed-sized blocks using a single secret key for both encryption and decryption.
Block Size: Each block of data processed by DES is 64 bits long.
Key Size: The key used for encryption and decryption is 56 bits long. However, 8 of these bits are parity bits used for error checking, leaving an effective key length of 48 bits.
DES was a significant development in cryptography but is considered less secure by modern standards due to its limited key size. Stronger encryption algorithms with larger key sizes are now widely used.
