The .cer file can be either PEM or DER format depending on what options are used. If it looks like a text file with a line like -----BEGIN CERTIFICATE----- its PEM. If its a binary file it DER. You can check that with: openssl x509 -in users.cer -text -noout [-inform DER] That wont help you much because the request to "use users.cer" is pretty meaningless. If they want you to use it as a client certificate then you can't because you don't have the private key. If it is a CA certificate then you can add it to your trusted root CAs. The output of the above command may give a hint as to what they want you to do. Steve. -- Dr Stephen N. Henson.
