Cryptography Questions Medium
A cryptographic algorithm is a set of mathematical rules and procedures used to encrypt and decrypt data. It is designed to ensure the confidentiality, integrity, and authenticity of information by transforming plaintext into ciphertext and vice versa. Cryptographic algorithms employ various techniques such as substitution, transposition, and mathematical operations to scramble the original data in a way that can only be reversed with the correct key or password. These algorithms are essential in modern cryptography for securing sensitive information, protecting communication channels, and verifying the identity of users.
