Deno Random Prime Numbers

Description

Generate random prime numbers with a desired bit-length and an optional number of tests.

Usage

Generate a Random Prime Number

randomPrime(bitlength, tests)

Where:

randomPrime() returns a bigint.
bitlength is a number.
tests is an optional number with a default value of 10.

Example:

import { randomPrime } from "https://deno.land/x/random_prime/mod.ts";

// Generate a random 1024-bit prime number with 10 primality tests
var prime: bigint = randomPrime(1024)

// Generate a random 2048-bit prime number with 20 primality tests
var prime: bigint = randomPrime(2048, 20)

Test if a BigInt is a Prime Number with Miller-Rabin

isProbablePrime(candidate, tests)

Where:

isProbablePrime() returns a boolean.
candidate is a bigint.
tests is an optional number with a default value of 10.

Example:

import { isProbablePrime } from "https://deno.land/x/random_prime/mod.ts";

// Have a number to test for primality
const candidate: bigint = 167n;

// Check if candidate is a probable prime with 10 primality tests
isProbablePrime(candidate) ? console.log("probable prime") : console.log("composite");
