I installed the latest WAMP (from wampserver.com) today on my Windows 7 computer.
I have enabled SSL in PHP > PHP Extensions > php_openssl
Wampserver with apache 2.4.4 released with wrong openssl files. All the things to do is: download and install the 1.0.1e openssl from here: http://slproweb.com/products/Win32OpenSSL.html
Then find these files in the installed directory:
bin\openssl.cfg
bin\libeay32.dll
bin\ssleay32.dll
bin\openssl.exe
Stop the apache server. at first, save a BACKUP of them. Then overright these files in your apache directory:
conf\openssl.cnf->rename the cfg here
bin\libeay32.dll
bin\ssleay32.dll
bin\openssl.exe
Restart the server. Solved.
