Utilize stream filters to verify the content of stream.
For example an md5 verification:
class MD5 extends \php_user_filter { private $context; public function onCreate() { $this->context = hash_init('md5'); return true; } public function onClose() { $hash = hash_final($this->context); if (false === hash_equals($this->params, $hash)) { throw new VerificationException('The stream integrity cannot be verified'); } return true; } public function filter($in, $out, &$consumed, $closing) { while ($bucket = stream_bucket_make_writeable($in)) { hash_update($this->context, $bucket->data); $consumed += $bucket->datalen; stream_bucket_append($out, $bucket); } return PSFS_PASS_ON; } }
This would be useful when downloading files (PHARs for example, when a hash is likely available)
