This is assuming you've used IIS to generate your CSR, sent it in, received your CRT file and imported the CRT file into IIS's Server Certificate manager. As far as I know, and have Googled, IIS is about the only way a server admin can easily create a CSR on Windows, so that is what I am going to assume you've used.
- Install the SSL version of UnrealIRCD.
- Export your certificate from the IIS Server Certificates icon in IIS. Using certmgr.msc will NOT work. We will assume you saved the file as server.pfx from here on.
- Copy the server.pfx file to your Unreal3.2 directory.
- Open up a command prompt, then navigate to your Unreal3.2 directory.
- Export the public key by running openssl.exe pkcs12 -in server.pfx -clcerts -nokeys -out server.cert.pem It will ask for an import password. This is the password you entered when you exported the pfx. If successful, you should get a "MAC verified OK" response.
- Export the private key by running openssl.exe pkcs12 -in server.pfx -nocerts -out temp.pem It will ask for the import password, then it will ask you to enter and verify a PEM passphrase. This will create an encrypted PEM file, which Unreal cannot use, so we have one more step.
- Export an unencrypted PEM from the previous file by running openssl rsa -in temp.pem -out server.key.pem This will ask for the PEM passphrase entered in the last step. If successful, it will export an unencrypted private key file.
