Arbitrary precision modular arithmetic, cryptographically secure random numbers and strong probable prime generation/testing.
It relies on the native JS implementation of (BigInt). It can be used by any Web Browser or webview supporting BigInt and with Node.js (>=10.4.0). The bundles can be imported directly by the browser or in Angular projects, React apps, Node.js, etc.
Secure random numbers are generated using the native crypto implementation of the browsers (Web Cryptography API) or Node.js Crypto. Strong probable prime generation and testing use Miller-Rabin primality tests and are automatically sped up using parallel workers both in browsers and Node.js.
The operations supported on BigInts are not constant time. BigInt can be therefore unsuitable for use in cryptography. Many platforms provide native support for cryptography, such as Web Cryptography API or Node.js Crypto.
bigint-crypto-utils
can be imported to your project with npm
:
1npm install bigint-crypto-utils
Then either require (Node.js CJS):
1const bigintCryptoUtils = require('bigint-crypto-utils')
or import (JavaScript ES module):
1import * as bigintCryptoUtils from 'bigint-crypto-utils'
The appropriate version for browser or node is automatically exported.
bigint-crypto-utils
uses ES2020 BigInt, so take into account that:
- If you experience issues using webpack/babel to create your production bundles, you may edit the supported browsers list and leave only supported browsers and versions. The browsers list is usually located in your project's
package.json
or the.browserslistrc
file.- In order to use
bigint-crypto-utils
with TypeScript you need to settarget
, andlib
andmodule
if in use, toES2020
in your project'stsconfig.json
.
You can also download the IIFE bundle, the ESM bundle or the UMD bundle and manually add it to your project, or, if you have already installed bigint-crypto-utils
in your project, just get the bundles from node_modules/bigint-crypto-utils/dist/bundles/
.
An example of usage could be (complete examples can be found in the examples directory):
1/* A BigInt with value 666 can be declared calling the bigint constructor as 2BigInt('666') or with the shorter 666n. 3Notice that you can also pass a number to the constructor, e.g. BigInt(666). 4However, it is not recommended since values over 2**53 - 1 won't be safe but 5no warning will be raised. 6*/ 7const a = BigInt('5') 8const b = BigInt('2') 9const n = 19n 10 11console.log(bigintCryptoUtils.modPow(a, b, n)) // prints 6 12 13console.log(bigintCryptoUtils.modInv(2n, 5n)) // prints 3 14 15console.log(bigintCryptoUtils.modInv(BigInt('3'), BigInt('5'))) // prints 2 16 17console.log(bigintCryptoUtils.randBetween(2n ** 256n)) // prints a cryptographically secure random number between 1 and 2**256 (both included). 18 19async function primeTesting (): void { 20 // Let us print out a probable prime of 2048 bits 21 console.log(await bigintCryptoUtils.prime(2048)) 22 23 // Testing if number is a probable prime (Miller-Rabin) 24 const number = 27n 25 const isPrime = await bigintCryptoUtils.isProbablyPrime(number) 26 if (isPrime === true) { 27 console.log(`${number} is prime`) 28 } else { 29 console.log(`${number} is composite`) 30 } 31} 32 33primeTesting() 34
