file-hasher

Node.js library for generating file hashes.

Installing

npm:

npm install file-hasher

yarn:

yarn add file-hasher

API

hashFile(path: string, callback: function, algorithm?: string, encoding?: string)

Asynchronously get the hash of the file at path. If no algorithm is specified, md5 shall be used as default. If no encoding is specified, 'hex' is used.

Examples

Usage with default settings (md5, hex)

const hashFile = require('file-hasher')

hashFile('index.js', (error, output) => {
  if (error) {
    throw error;
  }

  console.log(`hash is: ${output}`);
});

// hash is: 5be057751697d46af6d5fa2065a4b16c
});

Usage with specific hash algorithm and encoding

const hashFile = require('file-hasher')

hashFile('index.js', (error, output) => {
  if (error) {
    throw error;
  }

  console.log(`md5 hash with base64 encoding is: ${output}`);
}, 'sha256', 'base64');

// md5 hash with base64 encoding is: NUMulsRU7WYPv/hLS6ws7LZVMx53z5SnGhiB7bZ93qM=
