Introduction

A MD5 implementation for TypeScript

Can handle Unicode strings
Supports incremental hashing
Works with Files and Blobs

This library also includes tools for:

Hashing a file or blob
A webworker for performing hashing
A webworker handler for requesting files or blobs to be hashed
- promise based
- files or blobs are queued for processing on the webworker

Based on work by

Usage

Install

Install the node module with npm install ts-md5

Basic Hashing

Import the class
- import {Md5} from 'ts-md5';
Hash some things
- Md5.hashStr('blah blah blah') => hex:string
- Md5.hashStr('blah blah blah', true) => raw:Int32Array(4)
- Md5.hashAsciiStr('blah blah blah') => hex:string
- Md5.hashAsciiStr('blah blah blah', true) => raw:Int32Array(4)

For more complex uses:


md5 = new Md5();

// Append incrementally your file or other input
// Methods are chainable
md5.appendStr('somestring')
    .appendAsciiStr('a different string')
    .appendByteArray(blob);

// Generate the MD5 hex string
md5.end();

Hashing a File

NOTE:: You have to make sure ts-md5/dist/md5_worker.js is made available in your build so it can be accessed directly by a browser It should always remain as a seperate file.


import {ParallelHasher} from 'ts-md5';

let hasher = new ParallelHasher('/path/to/ts-md5/dist/md5_worker.js');
hasher.hash(fileBlob).then(function(result) {
   console.log('md5 of fileBlob is', result);
});
