Installation
------------

[](#installation)

Through [composer](http://getcomposer.org):

```
$ composer require bantu/stream-filter-hash
```

Usage
-----

[](#usage)

Use `HashFilter::appendToWriteStream($stream, $params)` to calculate a checksum of everything written to `$stream`. The `$params` argument has to be an array specifying the hash algorithm to use via the `algo` array key (e.g. `md5` or `sha256`). Furthermore `$params` either needs to be passed a callback via the `callback` array key or an output stream using the `stream` array key.

### Example using Stream

[](#example-using-stream)

Create an `output.txt.sha256` file containing a checksum of everything you write to `output.txt`.

```
require 'vendor/autoload.php';
$dest = fopen('output.txt', 'w+b');
$hash = fopen('output.txt.md5', 'w+b');
\bantu\StreamFilter\Hash\HashFilter::appendToWriteStream($dest, array(
    'algo' => 'sha256', 'stream' => $hash,
));
fwrite($dest, 'The quick brown fox jumps over the lazy dog');
fclose($dest);
fclose($hash);
```
