WebApr 11, 2024 · Symmetric ciphers are the opposite of asymmetric ciphers, like those used in public-key cryptography. These ciphers use asymmetric algorithms which use one key to encrypt data and a different key to decrypt ciphers. Typically, those two keys are called public and private keys, as is the case with RSA encryption. WebMar 10, 2024 · In cryptography, the most commonly used type of entropy is Shannon entropy, which was created by Claude Shannon, the father of information theory.
