+> Hashing made simple. Get the hash of a buffer/string/stream/file.
+
+[![Build Status](https://travis-ci.org/sindresorhus/hasha.svg?branch=master)](https://travis-ci.org/sindresorhus/hasha)
+
+Convenience wrapper around the core [`crypto` Hash class](https://nodejs.org/api/crypto.html#crypto_crypto_createhash_algorithm) with simpler API and better defaults.
+
+
+## Install
+
+```
+$ npm install --save hasha
+```
+
+
+## Usage
+
+```js
+var hasha = require('hasha');
+
+hasha('unicorn');
+//=> 'e233b19aabc7d5e53826fb734d1222f1f0444c3a3fc67ff4af370a66e7cadd2cb24009f1bc86f0bed12ca5fcb226145ad10fc5f650f6ef0959f8aadc5a594b27'
+```
+
+```js
+var hasha = require('hasha');
+
+// hash the process input and output the hash sum
+process.stdin.pipe(hasha.stream()).pipe(process.stdout);
+```
+
+```js
+var hasha = require('hasha');
+
+// get the MD5 hash of an image
+hasha.fromFile('unicorn.png', {algorithm: 'md5'}).then(function (hash) {
+	console.log(hash);
+	//=> '1abcb33beeb811dca15f0ac3e47b88d9'
+});
+```
+
+
+## API
+
+See the Node.js [`crypto` docs](https://nodejs.org/api/crypto.html#crypto_crypto_createhash_algorithm) for more about hashing.
+
+### hasha(input, [options])
+
+Returns a hash.
+
+#### input
+
+Type: `buffer`, `string`, `array` of `string`|`buffer`
+
+Buffer you want to hash.
+
+While strings are supported you should prefer buffers as they're faster to hash. Though if you already have a string you should not convert it to a buffer.
+
+Pass an array instead of concatenating strings and/or buffers. The output is the same, but arrays do not incur the overhead of concatenation.
+
+#### options
+
+##### encoding
+
+Type: `string`  
+Default: `hex`  
+Values: `hex`, `base64`, `buffer`, `binary`
+
+Encoding of the returned hash.
+
+##### algorithm
+
+Type: `string`  
+Default: `sha512`  
+Values: `md5`, `sha1`, `sha256`, `sha512`, etc *([platform dependent](https://nodejs.org/api/crypto.html#crypto_crypto_createhash_algorithm))*
+
+*The `md5` algorithm is good for [file revving](https://github.com/sindresorhus/rev-hash), but you should never use `md5` or `sha1` for anything sensitive. [They're insecure.](http://googleonlinesecurity.blogspot.no/2014/09/gradually-sunsetting-sha-1.html)*
+
+### hasha.stream([options])
+
+Returns a [hash transform stream](https://nodejs.org/api/crypto.html#crypto_class_hash).
+
+### hasha.fromStream(stream, [options])
+
+Returns a promise that resolves to a hash.
+
+### hasha.fromFile(filepath, [options])
+
+Returns a promise that resolves to a hash.
+
+### hasha.fromFileSync(filepath, [options])
+
+Returns a hash.
