Hi all,

In July when I've created my Master Key, I didn't use --expert option
and now my master key is Cert and Sign and got 2 subkey for encryption
(+1 revoke).

It's work well except that for, he use my first
encryption key and I can't decrypt it with my Smartcard.

So I thinking what is the best to do next:
- Delete my useless first subkey encryption from my keyring and send
update to key server.
- Recreate a new master key with only cert role and create all my subkey
(S E A) and copy it to my Smart Card.

What your advice on it ?? Nobody have sign my key and I can rencrypt my
