WebMay 19, 2024 · The RSA digital signature algorithm is a type of asymmetric cryptography. It’s asymmetric because it uses two separate keys: a Public Key and a Private Key. The Public Key is given to everyone, whereas the Private Key is kept private, as the name implies. Example of Asymmetric cryptography : WebRSA (Rivest–Shamir–Adleman) is an algorithm used by modern computers to encrypt and decrypt messages. It is an asymmetric cryptographic algorithm.Asymmetric means that there are two different keys.This is also called public key cryptography, because one of the keys can be given to anyone.The other key must be kept private.
