CRC

The library for calculating Cyclic Redundancy Check (CRC) for browser-side. The calculation is table-based. Tables are dynamically generated once per each CRC function.

This library is an adaptation and simplification of polycrc for use it on browser-side. CRC mathematics is checked with pycrc. It seems to be no other module in npm registry wich possible to use with Angular framework.

Even though this library was designed for browser-side it also keeps the possibility to use on nodejs-side.

Installation

npm install @dikman/crc

API

function crc24(str: string): Converter;

function crc32(str: string): Converter;

interface Converter {
  public toHEX(prefix: string = '0x'): string;
  public asNumber(): number;
}

Usage

Calculate a CRC32

import { crc32 } from '@dikman/crc';

const checksum = crc32('hello');

console.log(checksum.toHEX());
// "0x3610A686"

console.log(checksum.asNumber());
// 907060870

Calculate a CRC24

import { crc24 } from '@dikman/crc';

const checksum = crc24('hello');

console.log(checksum.toHEX());
// "0x47F58A"

console.log(checksum.asNumber());
// 4715914
