# what are the principal ingredients of a public key cryptosystem

Principal ingredients of a public-key cryptosystem are quite easy: You have two *different* keys (public and private). Public-key cryptography, or asymmetric cryptography, is a cryptographic system that uses pairs of keys: public keys, which may be disseminated widely, and private keys, which are known only to the owner.The generation of such keys depends on cryptographic algorithms based on mathematical problems to produce one-way functions.Effective security only requires keeping the private key … Plaintext, encryption algorithm, public and private keys, siphertext, decryption alorithm.
