Convert SSL Certificate .crt to PEM in any OS that runs WinRAR

Most likely your certificate authority will send you your SSL certificate in a zip file containing one or more files with the file extension .crt. If you just downloaded the certificate unzipped then you will have to put into an archive using a utility like WinRAR. I wont go into archiving here, you can find plenty of information on the web for that. Once you have your certificate(s) in an archive, open the archive to view the enclosed files with WinRAR. Once you can see the certificate right click on it and select ‘view file’ from the context menu. The file will open allowing you to view the PEM output.
