RSA is considered an asymmetric algorithm due to its use of a pair of keys. Its name is derived from the surnames of the three mathematicians ( Rivest, Shamir, and Adleman) who invented it. It also happens to be the very first asymmetric encryption algorithm. RSA is the most popular and widely used asymmetric encryption algorithm available to the public. In this article, we put our focus on the RSA algorithm. There exist various cryptographic algorithms for doing data encryption such as the DES (Data Encryption Standard), 3DES (Triple Data Encryption Standard), AES (Advanced Encryption Standard), RC4, and RSA (Rivest, Shamir, and Adleman) encryption among others. It is a data security practice for protecting sensitive information from being read by unauthorized parties.Īn encrypted data will appear scrambled and meaningless to anyone who tries to view read it and must be decrypted to be read and make sense. What is VPN, Private Network for Anonymity & Data Security What is encryption?Įncryption is the process of securing data by encoding it mathematically into an unreadable format known as ciphertext.
