WebApr 12, 2024 · The DES (data encryption standard) is one of the original symmetric encryption algorithms, developed by IBM in 1977. Originally, it was developed for and used by U.S. government agencies to protect sensitive, unclassified data. This encryption method was included in Transport Layer Security (TLS) versions 1.0 and 1.1. WebThe RSA algorithm uses prime numbers to generate the public and private keys. The following are the steps involved in RSA Encryption: Choose two prime numbers, p and q. Calculate n = p * q. Calculate the totient of n, phi = (p-1) * (q-1). Choose an integer e (1 < e < phi) that is co-prime with phi (i.e., gcd (e, phi) = 1).
