On the fly hash calculator for ReactPHP streams
To install via Composer, use the command below, it will automatically detect the latest version and bind it with ^.
composer require wyrihaximus/react-stream-hash
Writable stream:
$algo = 'sha512'; // Change to any desired algo from hash_algos()
$streamToHash = new ThroughStream();
// Constructor accepts a third $key argument in case you want a HMAC hash
$stream = new WritableStreamHash($streamToHash, $algo);
$stream->on('hash', function ($hash, $algo) {
// Do with what you need the hash for
});
$stream->on('hash_raw', function ($hash, $algo) {
// Do with what you need the raw hash for
});
// Write to the stream
$stream->write('foo');
$stream->end('bar');Readable stream:
$algo = 'sha512'; // Change to any desired algo from hash_algos()
$streamToHash = new ThroughStream();
// Constructor accepts a third $key argument in case you want a HMAC hash
$stream = new ReadableStreamHash($streamToHash, $algo);
$stream->on('hash', function ($hash, $algo) {
// Do with what you need the hash for
});
$stream->on('hash_raw', function ($hash, $algo) {
// Do with what you need the raw hash for
});
// The readable emits data when written to
$streamToHash->write('foo');
$streamToHash->end('bar');Please see CONTRIBUTING for details.
