PharData::setSignatureAlgorithm — Set the signature algorithm for a phar and apply it

Description

public function PharData::setSignatureAlgorithm(int $algo, ?string $privateKey = null): void

Note: This method requires the php.ini setting phar.readonly to be set to 0 in order to work for Phar objects. Otherwise, a PharException will be thrown.

Set the signature algorithm for a phar and apply it. The signature algorithm must be one of Phar::MD5, Phar::SHA1, Phar::SHA256, Phar::SHA512, or Phar::OPENSSL.

Parameters

algo

One of Phar::MD5, Phar::SHA1, Phar::SHA256, Phar::SHA512, or Phar::OPENSSL

Return Values

As a note, the docs don't show the (optional) second parameter nor mention the existence of the Phar::OPENSSL class constant also available for use with this method.

To sign a phar with OpenSSL, for example...

<?php

$phar = new Phar('somephar.phar');
// ... add your files and such
$phar->setSignatureAlgorithm(Phar::OPENSSL, file_get_contents('private_key_here.pem'));
// ... do whatever else you want afterwards here ...
?>

Hope this proves useful to someone.
