I am writing the authorization process for a program that's built on top of open social. The library that I am using is Oauth library. The certificate has been tested on other machines where it worked perfectly, though the exact same certificate does not work in my computer.
After I trace the error, the problem comes from this function: (inside oauth.php line:207)
$publickeyid = openssl_get_publickey($cert);
note : $cert is RSA Certificate
This function returns NULL on my computer, while it actually works (return valid value) when tested from the other computer. How can I fix this?
Does this have something to do with my Apache or local machine configuration? My php.ini and httpd.conf seem to be the same as the other machine also. I have been working on this things for several hours, and can't find any related solution in the Internet as well.
