Calculate powmod

A very simple library to calculate powmod from difference form of integer

Installation

npm install powmod

Usage

number

let x = 2, n = 3, g = 10
let r = powmod(g, x, n)

string

let x = '2', n = '3', g = '10'
let r = powmod(g, x, n)

bytearray

let x = [2], n = [3], g = [10]
let r = powmod(g, x, n)

big integer

let x = new BigInteger("2", 10), n = new BigInteger("3", 10), g = new BigInteger("10", 10)
let r = powmod(g, x, n)

mix data type

let x = new BigInteger("2", 10), n = "3", g = [10]
let r = powmod(g, x, n)

Test

npm test
