Hi, how are you?

I bought a new machine and I need to import my old secret keys, from the old

In the old machine, I was using the same version of GnuPG (1.0.6), in Red Hat

How can I do this?

I neet it for decrypt old emails and sign the new mails using the same old signature.

I just import one of my two signatures with the command:

$ gpg --import file.asc

But I can't sign files or encrypt with it.

Anyone can help me?

Thank you.
