Cybersecurity Defense and Offense: Symmetric Encryption

Symmetric encryption can be divided into block ciphers and stream ciphers. Block ciphers typically use a fixed size as the basic unit for processing, while stream ciphers use a single unit element (a letter or a bit) as the basic processing unit. Of course, when the block length is equal to the unit length, a … Read more
