Quick steps to configure SSL encryption on a WAMP server

There are a number of guides for this on the web, all of varying accuracy. These are the minimal steps I followed to get it working for development on a stock WAMP server installation:

1. Enable ssl_module in the Apache module list
2. Create the self-signed certificate keys as per Section 3 of http://tud.at/programm/apache-ssl-win32-howto.php3:

   cd c:\path\to\wamp\bin\apache\Apache2.2.11\conf
    
   # Set a PEM passphrase of 4 characters or more.  You can leave the challenge password blank.
   openssl req -config openssl.cnf -new -out my-server.csr
    
   # Set the "Common Name" to localhost, accepting the rest of the defaults.
   openssl rsa -in privkey.pem -out my-server.key
    
   openssl x509 -in my-server.csr -out my-server.cert -req -signkey my-server.key -days 365

3. In your conf/extra/httpd-vhosts.conf, add this:

   ### SSL
   # see http://www.modssl.org/docs/2.8/ssl_reference.html for more info
    
   # change this from "sem" to avoid startup errors
   SSLMutex default
    
   SSLRandomSeed startup builtin
   SSLSessionCache none
    
   Listen 443
   <VirtualHost *:443>
   ErrorLog logs/ssl.log
   LogLevel info
   # You can later change "info" to "warn" if everything is OK
    
   SSLEngine On
   SSLCertificateFile conf/my-server.cert
   SSLCertificateKeyFile conf/my-server.key
    
   # copy the <Directory> information from the appropriate HTTP virtual host
   DocumentRoot "C:/path/to/docroot"
   <Directory />
       ...
   </Directory>
   </VirtualHost>

4. Restart Apache.

That should do it, then just navigate to http://localhost:443. You’ll get browser warnings complaining that the certificate is self-signed and thus probably bogus, but it will work otherwise.
