Hello, You need to verify the files and check how they look like. A good guide to do this is this one http://how2ssl.com/articles/working_with_pem_files/ . .cert and .key are not actual formats, but might actually contain the cert and the key in PEM format. The main giveaway is that they should contain the header. If you will use the file for HAProxy, then you need the certificate and key in the same file. So you would do something like this: $ cat mycertificate.cert mykey.key > cert-and-key.pem And the resulting file is something you could use for your HAProxy instance. But again, it all depends on what you will use it for.
