PHP OpenSSL extension not working while installing TYPO3 CMS 7.4.0

Question

While installing TYPO3 CMS 7.4.0 I get the message:

PHP OpenSSL extension not working Something went wrong while trying to create a new private key for testing. Please check the integration of the PHP OpenSSL extension and if it is installed correctly.

Win 8.1 x64; PHP Version 5.6.12 VC11 x86 Thread Safe; Apache 2.4.16 VC11 Win32

I've read about similar issues and done everything recommended, but the problem is still here.

What I've done is:

• uncommented in php.ini extension=php_openssl.dll
• checked in phpinfo() that openssl is enabled: https://i.stack.imgur.com/yf7CF.png
• added an environment variable "OPENSSL_CONF" with values: https://i.stack.imgur.com/ZBtCB.png

• set path to 'openssl.exe':

  • set $TYPO3_CONF_VARS['SYS']['binSetup'] in
    ...\typo3\sysext\core\Configuration\DefaultConfiguration.php to 'openssl=C:\Apache24\bin\openssl.exe'

• appended C:\Apache24\bin\ to the environment variable PATH

• restarted apache/rebooted PC.

And nothing helped.

1. What else would you recommend to check?
2. How to execute the function openssl_pkey_new() using cmd and check if there's a problem with openssl?

EDIT:

1. I've carefully read openssl.installation manual from official php site (sry, am not able to post more than 2 links due to lack of reputation here ^^) and nothing helped

2. When I run this script: error_reporting(E_ALL);$test = openssl_pkey_new();echo $test;

I get a blank page in my browser (while 'display_errors = On' and 'display_startup_errors = On' in php.ini)

3. Installed XAMPP.

In the shell on XAMPP control panel, openssl command gives

WARNING: can't open config file: C:/xampp/apache/bin/openssl.cnf OpenSSL>

While openssl.cnf is located in C:/xampp/apache/conf/openssl.cnf And in PHP Variables there's _SERVER["OPENSSL_CONF"] C:/xampp/apache/conf/openssl.cnf

In the CMD openssl command gives

C:\WINDOWS\system32>openssl WARNING: can't open config file: D:\tmp\openssl-1.0.1p\vc11\x86/openssl.cnf OpenSSL>

4. Both libeay32.dll and ssleay32.dll are of version 1.0.1.16 and are the same in apache/bin and /php

5. There's SetEnv OPENSSL_CONF "C:/xampp/apache/conf/openssl.cnf" in httpd-xampp.conf

Answer 1

1. Please try all optiones mentioned here: http://php.net/manual/en/openssl.installation.php

2. You can use php -a to open a php shell and run the mentioned command. Or you can write yourself a minimalistic php file and run that from your browser:

   <?php
   error_reporting(E_ALL);
   $test = openssl_pkey_new();
   echo $test;
