Install

bun add @knownasrazi/checksum
npm install @knownasrazi/checksum

Usage

import { crc32, crc32Hex, sha256, md5, fileChecksum } from "@knownasrazi/checksum";

crc32("hello"); // number
crc32Hex("hello"); // "3610a686"
await sha256("abc"); // "ba7816bf8f01cfea414140de5dae2223b00361a39617..."
await md5("hello"); // "5d41402abc4b2a76b9719d911017c592"
const { crc32: c, sha256: s } = await fileChecksum(Bun.file("package.json"));
