WebAug 27, 2024 · Public key cryptography is both a powerful and useful form of cryptography that allows anyone to send an encrypted message to another individual. The basic idea is that an individual who wants to send a private message must first encrypt the message with the receiver's public key. 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.

A naive method of finding a modular inverse for A (mod C) is: step 1. Calculate A * B mod C for B values 0 through C-1. step 2. The modular inverse of A mod C is the B value that makes A * B mod C = 1. Note that the term B mod C can only have an integer value 0 through C-1, so testing larger values for B is redundant. lamparas ovalamp
