Q

CBC

A

Cipher Block Chaining

Cipher Block Chaining (CBC) is a way to encrypt information in chunks. Each chunk is scrambled with the key, and then also linked to the previous chunk with a special operation. This chaining effect makes decryption rely on all the previous blocks, improving security compared to simpler encryption methods.
