Webb17 dec. 2016 · A cryptographic system uses two dissimilar keys - a public key known to all and a private key known only to the receiver of the message. Encryption of the data uses public key while decryption uses both public and private keys. So in this method all parties need a key pair for conversing with any other interactive parties. RSA is a generally … WebbThis is also referred to as Tic-Tac-Toe Cipher, and is fairly simple substitution cipher. The letters of the alphabet are replaced by fragments of a geometrical grid.
