WebRSA algorithm (Rivest-Shamir-Adleman): RSA is a cryptosystem for public-key encryption , and is widely used for securing sensitive data, particularly when being sent over an insecure network such as the Internet . WebCryptographic communication and authentication Paul Krzyzanowski Introduction to cryptography We will refer to a message that is readable, or not encrypted, as plaintext, cleartext and denote it with the symbol M. The process of disguising a message to hide its substance is called encryption. We will represent this operation as E(M). Webthe cipher algorithm works on a fixed-size block of data. For example, if the block size is eight, eight bytes of plaintext are encrypted at a time. Normally, the user's interface to the encrypt/decrypt operation handles data longer than the block size by repeatedly calling the low-level cipher function.
