Phar stubs and signatures

Hi, Is there any reason why we can't use Phar::setSignatureAlgorithm() after Phar::setStub()? https://github.com/defuse/php-encryption/pull/139 PHP Fatal error: Uncaught exception 'PharException' with message 'unable to copy stub of old phar to new phar "/var/www/defuse/php-encryption/dist/defuse-crypto.phar"' in /var/www/defuse/php-encryption/other/build_phar.php:37 Stack trace: #0 /var/www/defuse/php-encryption/other/build_phar.php(37): Phar->setSignatureAlgorithm(16, '-----BEGIN PRIV...') #1 {main} thrown in /var/www/defuse/php-encryption/other/build_phar.php on line 37 If there's a reason this shouldn't allowed, could the documentation please be updated to reflect this decision? If this is a bug, it's breaking our ability to publish signed a .phar for defuse/php-encryption (And if I somehow overlooked something, please let me know.)
