RSA
The best known of the two-key cryptosystems developed in the mid-1980s is the Rivest-Shamir-Adleman (RSA) cryptoalgorithm, which was first published in April, 1977. Since that time, the algorithm has been employed in the most widely-used Internet electronic communications encryption program, Pretty Good Privacy (PGP). It is also employed in both the Netscape Navigator and Microsoft Explorer web browsing programs in their implementations of the Secure Sockets Layer (SSL), and by Mastercard and VISA in the Secure Electronic Transactions (SET) protocol for credit card transactions.
