Symmetric Cryptosystem A cryptosystem that uses the same key to encrypt and decrypt information Asymmetric Cryptosystem.The reason this is guaranteed to work is the linearity of modulus, i.e., that the linear combination of the remainders equals the remainder of the linear combination.So far, we have seen the creation of secure communication after secret parameters (keys) have been securely exchanged, but the problem of exchanging the parameters over a public channel remains.Six years after its creation, the MH cryptosystem was broken with an attack by A. Shamir. There were several more attempts to revive MH, many of which also failed.An example that is actually utilized in the RSA cryptosystem is multiplying big primes versus factoring the resulting product without already knowing the factors.This demo lets you send and receive secret messages using two kinds of encryption.
