PHP openssl_sign stops any scripts

I'm having problems with openssl. To better identify the problem, I did two things; I reduced the code to one test page (which I received from php.net). And after the problem persisted, I uploaded the tat code to the server. The server worked as expected, so the problem should be in my setup !? I found someone who experienced the same problem, but his code was different and the solution did not work for me ( Google Analytics V3 Application Services and APIs: Error 101 (net :: ERR_CONNECTION_RESET) ).

This is the code:

<?php $data = "Beeeeer is really good.. hic..."; // You can get a simple private/public key pair using: // openssl genrsa 512 >private_key.txt // openssl rsa -pubout <private_key.txt >public_key.txt // IMPORTANT: The key pair below is provided for testing only. // For security reasons you must get a new key pair // for production use, obviously. $private_key = <<<EOD -----BEGIN RSA PRIVATE KEY----- MIIBOgIBAAJBANDiE2+Xi/WnO+s120NiiJhNyIButVu6zxqlVzz0wy2j4kQVUC4Z RZD80IY+4wIiX2YxKBZKGnd2TtPkcJ/ljkUCAwEAAQJAL151ZeMKHEU2c1qdRKS9 sTxCcc2pVwoAGVzRccNX16tfmCf8FjxuM3WmLdsPxYoHrwb1LFNxiNk1MXrxjH3R 6QIhAPB7edmcjH4bhMaJBztcbNE1VRCEi/bisAwiPPMq9/2nAiEA3lyc5+f6DEIJ h1y6BWkdVULDSM+jpi1XiV/DevxuijMCIQCAEPGqHsF+4v7Jj+3HAgh9PU6otj2n Y79nJtCYmvhoHwIgNDePaS4inApN7omp7WdXyhPZhBmulnGDYvEoGJN66d0CIHra I2SvDkQ5CmrzkW5qPaE2oO7BSqAhRZxiYpZFb5CI -----END RSA PRIVATE KEY----- EOD; $public_key = <<<EOD -----BEGIN PUBLIC KEY----- MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBANDiE2+Xi/WnO+s120NiiJhNyIButVu6 zxqlVzz0wy2j4kQVUC4ZRZD80IY+4wIiX2YxKBZKGnd2TtPkcJ/ljkUCAwEAAQ== -----END PUBLIC KEY----- EOD; $binary_signature = ""; // At least with PHP 5.2.2 / OpenSSL 0.9.8b (Fedora 7) // there seems to be no need to call openssl_get_privatekey or similar. // Just pass the key as defined above openssl_sign($data, $binary_signature, $private_key, "sha1"); // Check signature $ok = openssl_verify($data, $binary_signature, $public_key, "sha1"); echo "check #1: "; if ($ok == 1) { echo "signature ok (as it should be)\n"; } elseif ($ok == 0) { echo "bad (there something wrong)\n"; } else { echo "ugly, error checking signature\n"; } $ok = openssl_verify('tampered'.$data, $binary_signature, $public_key, "sha1"); echo "check #2: "; if ($ok == 1) { echo "ERROR: Data has been tampered, but signature is still valid!
