WebJan 12, 2024 · During the 16th century, Vigenere designed a cipher that was supposedly the first cipher which used an encryption key. In one of his ciphers, the encryption key was repeated multiple times spanning the entire message, and then the cipher text was produced by adding the message character with the key character modulo 26.

WebRSA algorithm follows a block cipher encryption technique, in which the plaintext and the cipher are integers between 0 and n – 1 for some n. A typical size for n is 1024 bits, or 309 decimal digits. That is, n is less than to1024.RSA algorithm has three major steps. 1. Key generation 2. Encryption 3. Decryption Algorithm 1.
