# sha1-uint8array
[](https://github.com/kawanet/sha1-uint8array/actions/)
[](https://www.npmjs.com/package/sha1-uint8array)
[](https://cdn.jsdelivr.net/npm/sha1-uint8array/dist/sha1-uint8array.min.js)
Fast SHA-1 digest hash based on Uint8Array, pure JavaScript.
## SYNOPSIS
```js
import {createHash} from "sha1-uint8array";
const text = "";
const hex = createHash().update(text).digest("hex");
// => "da39a3ee5e6b4b0d3255bfef95601890afd80709"
const data = new Uint8Array(0);
const hash = createHash().update(data).digest();
// =>
```
See TypeScript declaration
[sha1-uint8array.d.ts](https://github.com/kawanet/sha1-uint8array/blob/main/types/sha1-uint8array.d.ts)
for detail.
## COMMONJS
Both ES Modules and CommonJS supported.
```js
const {createHash} = require("sha1-uint8array");
```
## COMPATIBILITY
It has a better compatibility with Node.js's `crypto` module in its smaller footprint.

The W3C standard `crypto.subtle.digest()` API has a different interface which
[returns](https://github.com/microsoft/TypeScript/blob/master/lib/lib.dom.d.ts)
`Promise`.
## SPEED
It runs well both on Node.js and browsers.
Node.js's native `crypto` module definitely runs faster than any others on Node.js, though.
|module|version|node.js V14|Chrome 87|Safari 14|
|---|---|---|---|---|
|[crypto](https://nodejs.org/api/crypto.html)|-|69ms 👍|N/A|N/A|
|[sha1-uint8array](http://github.com/kawanet/sha1-uint8array)|0.10.0|251ms|352ms 👍|202ms 👍|

The benchmark above shows milliseconds for 20,000 times of
SHA-1 `hex` hash digest generation for approx 1KB string as input.
It is tested on macOS 10.15.7 Intel Core i7 3.2GHz.
You could run the benchmark as below.
```sh
git clone https://github.com/kawanet/sha1-uint8array.git
cd sha1-uint8array
npm install
npm run build
# run the benchmark on Node.js
REPEAT=10000 ./node_modules/.bin/mocha test/99.benchmark.js
# run tests and the benchmark on browser
make -C browser
open browser/test.html
```
## WEB BROWSERS
- The minified build of the library is also available for Web browsers via
[jsDelivr CDN](https://www.jsdelivr.com/package/npm/sha1-uint8array).
- https://cdn.jsdelivr.net/npm/sha1-uint8array/dist/sha1-uint8array.min.js
- Live Demo https://kawanet.github.io/sha1-uint8array/
```html
const text = "";
const hex = SHA1.createHash().update(text).digest("hex");
// => "da39a3ee5e6b4b0d3255bfef95601890afd80709"
const data = new Uint8Array(0);
const hash = SHA1.createHash().update(data).digest();
// => <Uint8Array da 39 a3 ee 5e 6b 4b 0d 32 55 bf ef 95 60 18 90 af d8 07 09>
```
## BROWSERIFY
It works great with
[browserify](https://www.npmjs.com/package/browserify)
via `browser` property of `package.json` of your app if you needs
`crypto.createHash("sha1").update(data).digest("hex");` syntax only.
```json
{
"browser": {
"crypto": "sha1-uint8array/dist/sha1-uint8array.min.js"
},
"devDependencies": {
"browserify": "^17.0.0",
"sha1-uint8array": "^0.10.0"
}
}
```
It costs only less than 3KB, whereas `browserify`'s default `crypto` polyfill
costs more than 300KB huge even after minified.
```js
// On Node.js, this loads Node.js's native crypto module which is faster.
// On browsers, this uses sha1-uint8array.min.js which is small and fast.
const crypto = require("crypto");
const hash = crypto.createHash("sha1").update("").digest("hex");
// => "da39a3ee5e6b4b0d3255bfef95601890afd80709"
```
