WAMP is unable to generate private key when using OpenSSL

I am working on OpenSSL in Windows 8.1, Wamp Apache Version: 2.4.9 PHP Version: 5.5.12. And I ended up with the following error:

enter image description here

My PHP code is given below. WAMP is unable to generate private key. 

$privateKey = openssl_pkey_new(array(
    'private_key_bits' => 384,      // Size of Key.
    'private_key_type' => OPENSSL_KEYTYPE_RSA,
));

openssl_pkey_export($privateKey, $privKey, null, ['config' =>   'C:/wamp/bin/apache/apache2.4.9/conf/openssl.cnf']);
$a_key = openssl_pkey_get_details($privateKey);

file_put_contents('keys/'.$username.'_public.key', $a_key['key']);
file_put_contents('keys/'.$username.'_private.key', $privKey);
openssl_free_key($privateKey);

Can anyone please help me in running OpenSSL in Windows. Thanks in advance.

I had similiar problem and I figured out, that WAMPserver do not have default CA installed. How to fix it:

Also make sure that OPENSSL_CONF environmental variable is set to c:\wamp\bin\apache\apache2.4.9\conf\openssl.cnf

Your question isn't much specific but I can say that you're calling openssl_pkey_export with wrong fourth argument. It should be array with config key instead of just string. config key is needed also for openssl_pkey_new. 

<?php

$privateKey = openssl_pkey_new([
    'private_key_bits' => 384,
    'private_key_type' => OPENSSL_KEYTYPE_RSA,
    'config' => 'C:/wamp/bin/apache/apache2.4.9/conf/openssl.cnf'
]);

openssl_pkey_export($privateKey, $privKey, null, [
    'config' => 'C:/wamp/bin/apache/apache2.4.9/conf/openssl.cnf'
]);

$a_key = openssl_pkey_get_details($privateKey);

var_dump($privKey); // Just to test output

file_put_contents('keys/'.$username.'_public.key', $a_key['key']);
file_put_contents('keys/'.$username.'_private.key', $privKey);

openssl_free_key($privateKey);

Hope that's help
