Yes, you can gnerate a new key pair with the same user ID email, the key server will accept it. Do not forget to generate a revocation certificate and to store in a safe place. You might want to indicate in the comment of the new key that the previous key (key ID) is not usable, if yoi plan to upload the new public key to a key server

Bad news yes. But well, nobody's dead.
It's even quite funny in fact, thinking about how often I repeat to
everybody that they need to make backup of everything.

This key is the only thing I loose, I will juste made another one.

And no, I don't have the revocation certificate :(
But I think it's not too bad, because nobody had access to this private
key. I just loose it...

Small and last question, If I make a new key, with the same email
inside, will I be able to send it on servers ? (because they already got
the old one...)

Thanks a lot for your time.


I'm afraid these are not the same key :(

The former key is a 4096-bit RSA key. The latter key is a 1024-bit DSA
key with a 4096-bit ElGamal subkey bound to it.

Also, the former key has an X.509 certificate assoiated with it, while
the latter keys are bound to your identity via OpenPGP certification.
While it's possible to have both X.509 certificates and OpenPGP
certificates from the same key (we're doing it for TLS servers in the
monkeysphere project), it's not common. And in your case, it's not what
you've done anyway, since these are clearly different keys because of
their different keylengths and algorithms.

If you have no way of recovering your old ~/.gnupg/secring.gpg, you have
most likely lost control of your old key.  In that case, i recommend
publishing the revocation certificate you created when you made your key
(hoping that you have such an old revocation certificate for 1F03B55A
stored someplace accessible to you).

Sorry to be the bearer of bad news,
