Web5 Popular Asymmetric Encryption Example descriptions 1. Rivest Shamir Adleman (RSA) RSA is a widely used asymmetric encryption example used to encrypt data sent over insecure networks. Ron Rivest, Adi Shamir, and Leonard Adleman first described the RSA algorithm in 1977, thus the acronym RSA. WebJul 19, 2024 · A hybrid cryptosystem consists of both an asymmetric algorithm for key establishment and a symmetric cipher. You are correct in that you establish a symmetric key, and yes, that can be done by encrypting it with a public key. Note that that public key needs to be trusted. Otherwise an adversary could supplant it with his own public key.
