How To: Export SSL Certificate from Linux to Windows IIS

I just had to figure this out by myself because the title of this thread returned no relevant results in Google. This is the quick and dirty. Hope you can follow along.

Step 1: pem file
You will need to log into your linux box and create a .pem file that contains your private key and your certificate hash. Your private key is usually in a .key file and your certificate is usually in a .crt file. Just paste the content of your key and certificate files into the same file (in that order, separated by a line break) and save it as "whatever.pem".

Step 2: p12 file
The p12 file is what IIS wants. To create it, use the following command in linux:

openssl pkcs12 -export -in whatever.pem -out whatever.p12 "Whatever Certificate"

You'll be asked to provide a password for the file. Remember it for the next step. After you've done this, transfer whatever.p12 to your windows server (FTP, anyone?).

Step 3: Import the p12 file in IIS
Go to the properties of your website in IIS, then into the Directory Security tab. Click on "Server Certificate" and select the "Import" option. When it asks you to find the file, make sure to change the scope to "All files" to find the p12. When you select the file, you'll be asked to enter the password you selected in step 2. Et voila! Successfully transferred SSL Certificate from Linux to Windows.

Don't forget to install a valid CA Root Certificate while you're at it. You can actually find a tutorial for that online though.
