When I run the test script I've pasted in the "test script" section of this bug 
report, I get the warnings shown under "actual result" of this bug report.

I'm running this code on Windows Servef 2008 R2. I have tried running this exact 
same code under both PHP 5.4.3 and PHP 5.3.13.

(However, the code works just fine on Mac OS X 10.7.4, using PHP version 5.3.10.)

Test script:

$privateKey = openssl_pkey_new(array(
  'private_key_bits' => 1024,
  'private_key_type' => OPENSSL_KEYTYPE_RSA,

openssl_pkey_export_to_file($privateKey, 'private_key', "somepassword");

$keyDetails = openssl_pkey_get_details($privateKey);
file_put_contents('public_key', $keyDetails['key']);


Expected result:
I expect two files to get output, one with a private key and another with a 
public key. In fact, this is exactly what happens on Mac OS X (as described in 
the "description" section of this bug report). On Windows, it's for some reasons 
not working, as described in the "actual result" section of this bug report.

Actual result:
When I run the script on the command prompt (using "cd <path to script>" and "
<path to php>\php.exe <path to script>\script.php"), I get the following output:

PHP Warning:  openssl_pkey_export_to_file(): cannot get key from parameter 1 in 
C:\Users\Administrator\Documents\script.php on line 8
PHP Warning:  openssl_pkey_get_details() expects parameter 1 to be resource, 
boolean given in C:\Users\Administrator\Documents\script.php on line 11

What ends up happening is that only one EMPTY file 'public_key' gets created.

Is the directory writeable by PHP? (Not familiar with Windows environments)

What happens if you do this?

$privateKey = openssl_pkey_new(array(
  'private_key_bits' => 1024,
  'private_key_type' => OPENSSL_KEYTYPE_RSA,


if(openssl_pkey_export_to_file($privateKey, 'private_key', "somepassword")) {
  $keyDetails = openssl_pkey_get_details($privateKey);
  file_put_contents('public_key', $keyDetails['key']);
} else {

Your script gives me the following output:

PHP Warning:  openssl_pkey_export_to_file(): cannot get key from parameter 1 in 
C:\Users\Administrator\Documents\script.php on line 10

The problem, therefore, appears to be in the key generation function. It's the 
var_dump call that is outputting


Interestingly, the same var_dump outputs the following on Mac OS X:

resource(4) of type (OpenSSL key)

So it's working fine on Mac OS X, but not on Windows. Any ideas why?

I fixed this "problem" by setting up the environmental variables as described 

I have marked this non-bug as closed, Thanks for your help, and sorry for wasting 
your time.
