Importing certificates as keys

[Ph. Marek]

Hello everybody,

I have a (possibly) stupid question.

If I have a certificate (eg. for use with SSL), which has also dataEncryption 
and keyEncryption as keyusages defined, is there a ways to import that key 
into gpg?
With openssl I can get the values by using a command like
	openssl rsa -text -in privkey.pem
which dumps my the information, eg.
	Private-Key: (512 bit)

I expect that this information should be more than enough to specify the key 
for gpg.

I believe I read something a long time ago about specifying the various values 
for generating a key - I just don't remember where and which product 
(openssl, gpg, or something else).

Nevertheless -. is there a way to import the pem- or pkcs12-file or some other 
information (text dump above) to use my key in gpg?

This would be easier than giving all users another key, which they would have 
to have with them. If it could just get generated from the certificate or 
possibly used directly ...


Thank you for all answers!
