Cryptography in JavaScript

Overview

This module is being developed as a part of Cryptography with elements of algebra course. It includes implementation of basic and advanced algorithms, including cryptographic algorithms.

Module 1

Module 1 includes basic algorithms:

• addBinary: school addition algorithm,
• multiplyBinary: division with remainder algorithm,
• divideBinary: school multiplication algorithm,

and advanced algorithms:

• findInverse: finding an inverse modulo n,
• fastPower: fast power algorithm,
• isSquare: algorithm which checks whether an element is a square modulo p,
• squarePrime: algorithm which finds a square root of a square modulo p,
• fermat: algorithm which checks the primality using Fermat's test.
