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. Webthe cryptosystem is fully aware of the public key and any algorithms that may be used as part of the cryptosystem; the only piece of information that is denied to the attacker is the private key. Typically, asymmetric cryptosystems are based on the computation of large numerical values and are a lot slower than their symmetric
