WebVarious PARI/GP commands will be introduced that can help us to perform basic number theoretic operations such as greatest common divisor and Euler’s phi function. We then introduce the RSA cryptosystem and use PARI/GP’s built-in commands to encrypt and decrypt data via the RSA algorithm. WebThe cipher's primary weakness comes from the fact that if the cryptanalyst can discover (by means of frequency analysis, brute force, guessing or otherwise) the plaintext of two ciphertext characters then the key can be obtained by solving a simultaneous equation.
