- Cryptography is the study of protecting information. A cipher is a pair of algorithms ―the first algorithm encrypts a message and the second algorithm decrypts the message. In most cases, a unique key is also required to encode or decode plaintext. The Caesar cipher is one of the simplest and most widely known ciphers. It is named after Julius Caesar who allegedly used it to protect important military directives. Every letter in the plaintext is replaced by a letter N positions down the alphabet. For example, if N = 3, then a => d and b => e. While the idea is remarkably simple, it appeared to work in Ancient Rome. Most people there couldn't read, and those who could simply assumed it was a foreign language. Write a program that implements the Caesar cipher. You program will get from standard input the key N, followed by a line of plaintext. . . The key N should be any integer between 0 and 26 inclusive. If this isn't the case, print an error message and quit. Any numbers or…To verify a signature on a message from Alice, Bob uses Alice's public key Alice's private key his private key his public keyCryptography: Using the Euclidean Algorithm find the greatest common divisor (gcd) of the following: a) 155 37 b) 1114978 23456 c) 110010105 750
