What is sumchecker?

The sumchecker npm package is used to verify the integrity of files by checking their checksums against known values. This is particularly useful for ensuring that files have not been tampered with or corrupted during download or transfer.

What are sumchecker's main functionalities?

Checksum Verification

This feature allows you to verify the checksums of multiple files against a checksum file. The code sample demonstrates how to use the sumchecker package to verify the integrity of 'file1.zip' and 'file2.zip' using SHA-256 checksums listed in 'checksums.txt'.

const sumchecker = require('sumchecker');
const path = require('path');

const checksumFile = 'checksums.txt';
const baseDir = path.join(__dirname, 'downloads');
const files = ['file1.zip', 'file2.zip'];

sumchecker('sha256', checksumFile, baseDir, files)
  .then(() => {
    console.log('All files verified successfully');
  })
  .catch((err) => {
    console.error('Checksum verification failed', err);
  });
