"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. " - First practical asymmetric cryptosystem
