Cryptography is an art of information security, whose fundamental objective is the security of the message which is being transferred through an insecure medium between two parties i.e. sender and the receiver. There are two Cryptosystem: private and public key cryptosystem. This paper is about the overview of the two public key cryptography systems RSA and ElGamal Cryptosystem. RSA uses the base of Integer Factorization while ELGamal Cryptosystem uses the base of Discrete Logarithm Problem
