I'd also suggest looking at the file contents. If it looks like base64 data of the form: -----BEGIN XXX----- <base64 stuff> -----END XXX----- Where XXX is some string such as "RSA PRIVATE KEY" then it is probably PEM format. If the file looks like binary data then try: openssl asn1parse -inform DER -in key.dat if you get errors then it may be some proprietary format and you are out of luck. Otherwise you might want to try the pkcs8 or pkcs12 utilities on it. If you can generate a test key you could send that as an attachment to see if anyone recognizes the format.
