I have a PHP program that uses OpenSSL to do RSA decryption that works when I run it on my remote Linux (Ubuntu) webserver, but fails when I run it under Windows (launched from PHPstorm, using PHP's built-in web server).
I generated the private key using OpenSSL under Windows:
openssl genrsa -out private.pem 2048
Here's the PHP code that works under Linux, but fails under Windows:
$req = "R6lnBb8Hhu5YEmVvdJKUEzckq5afHGFauRca3q6+NuPf1Jrx0+5WtCFj+uFrCBkQtu7sqCoZ+nIh
" .
"oLqn5GHn6rLAI03kiB3USrV232LKiamzepk1mHxaMQ+q+um95XETnuCrDfH+ufTsErNo2IjhAGjF
" .
"6SxQxA00+HpMBtu/lSKCz2x67rG3g4zdhnUXRsBlO3T0iX8S0loudklc34Phfa/4EqR14Vcb0Z7b
" .
"Z1UdLxYJEhW32Rnk4iXZV0ChpkiNdSTOH+GfRJpKR0VwdbfuBGDtV8ktzxiNsNFaA/n4XNKPB2LU
" .
"9CCyi+s6zYbXvayxFTcVPVMxM0zBOfa45j9nYw==";
$cryptext = base64_decode($req);
$path = 'file:///' . __DIR__ . DIRECTORY_SEPARATOR . 'private.pem';
// file_exists($path) confirmed to return true when run on both platforms.
$res = openssl_pkey_get_private($path);
openssl_pkey_export($res, $privatekey);
echo "
Private Key:$privatekey
<HR>
";
openssl_private_decrypt($cryptext, $decrypted, $privatekey);
echo("$req
<HR>
");
echo("$decrypted");
(correct) Output when run on LINUX server:
file exists
<hr>

I'm pretty sure this is primarily due to Windows-specific funkiness that goes beyond 0x0D 0x0A newlines vs 0x0A newlines... as an experiment, I converted the .pem file to use Windows-style newlines, but it still failed under Windows.
