[TYPO3-english] rsaauth problem in xampp

[J. Bakshi (জ বকসী)]

Dear list,

A Window related typo3 issue. I have migrated a typo3 4.6.4 site on a XP box running xampp.
The FE is working well. But at BE I get the following error 

`````
No OpenSSL backend could be obtained for rsaauth.

``````

Though at php.ini I have 

`````
extension=php_openssl.dll

` ` ` 

and through phpinfo I can confirm openssl is active.


Also tried with 

````
$TYPO3_CONF_VARS['BE']['loginSecurityLevel'] = 'normal';
`````

but the same error

Could anyone kindly suggest how to fix it ?

Thanks
