# md5-hex [](https://travis-ci.org/sindresorhus/md5-hex)
> Create a MD5 hash with hex encoding
*Please don't use MD5 hashes for anything sensitive!*
Checkout [`hasha`](https://github.com/sindresorhus/hasha) if you need something more flexible.
## Install
```
$ npm install --save md5-hex
```
## Usage
```js
var fs = require('fs');
var md5Hex = require('md5-hex');
var buffer = fs.readFileSync('unicorn.png');
md5Hex(buffer);
//=> '1abcb33beeb811dca15f0ac3e47b88d9'
```
## API
### md5Hex(input)
#### input
Type: `buffer`, `string`
Prefer buffers as they're faster to hash, but strings can be useful for small things.
