WebApr 6, 2024 · Cryptography The oldest method of ensuring the security and privacy of data transmitted via networks is cryptography. The information is scrambled (or encrypted) to make it incomprehensible or difficult to understand, and only the authorized user can decode it (or decrypt it). WebOne method of cryptography is symmetric cryptography (also known as secret key cryptography or private key cryptography ). Symmetric cryptography is best suited for bulk encryption because it is much faster than asymmetric cryptography. With symmetric cryptography: • Both parties share the same key (which is kept secret).
