Package Exports

js-sha1
js-sha1/src/sha1.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (js-sha1) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Installation

You can also install js-sha1 by using Bower.

bower install js-sha1

For node.js, you can use this command to install:

npm install js-sha1

Notice

NIST formally deprecated use of SHA-1 in 2011 and disallowed its use for digital signatures in 2013, and declared that it should be phased out by 2030. However, SHA-1 is still secure for HMAC. wiki

Usage

You could use like this:

sha1('Message to hash');
var hash = sha1.create();
hash.update('Message to hash');
hash.hex();

// HMAC
sha1.hmac('key', 'Message to hash');

var hash = sha1.hmac.create('key');
hash.update('Message to hash');
hash.hex();

Node.js

If you use node.js, you should require the module first:

var sha1 = require('js-sha1');

TypeScript

If you use TypeScript, you can import like this:

import { sha1 } from 'js-sha1';

RequireJS

It supports AMD:

require(['your/path/sha1.js'], function(sha1) {
// ...
});

Example

sha1(''); // da39a3ee5e6b4b0d3255bfef95601890afd80709
sha1('The quick brown fox jumps over the lazy dog'); // 2fd4e1c67a2d28fced849ee1bb76e7391b93eb12
sha1('The quick brown fox jumps over the lazy dog.'); // 408d94384216f890ff7a0c3528e8bed1e0b01621

// It also supports UTF-8 encoding
sha1('中文'); // 7be2d2d20c106eee0836c9bc2b939890a78e8fb3

// It also supports byte `Array`, `Uint8Array`, `ArrayBuffer`
sha1([]); // da39a3ee5e6b4b0d3255bfef95601890afd80709
sha1(new Uint8Array([])); // da39a3ee5e6b4b0d3255bfef95601890afd80709

// Different output
sha1(''); // da39a3ee5e6b4b0d3255bfef95601890afd80709
sha1.hex(''); // da39a3ee5e6b4b0d3255bfef95601890afd80709
sha1.array(''); // [218, 57, 163, 238, 94, 107, 75, 13, 50, 85, 191, 239, 149, 96, 24, 144, 175, 216, 7, 9]
sha1.digest(''); // [218, 57, 163, 238, 94, 107, 75, 13, 50, 85, 191, 239, 149, 96, 24, 144, 175, 216, 7, 9]
sha1.arrayBuffer(''); // ArrayBuffer

// HMAC
sha1.hmac.hex('key', 'Message to hash');
sha1.hmac.array('key', 'Message to hash');
// ...
