UIDs are not stored on the smartcard, so it does not matter.

Understandable. If I understand correctly, you used GnuPG to encrypt the file
that unlocks your netbook? In that case, the *uid commands should be safe,
because they do not influence decryption of files. To be on the safe side, keep
a copy of your key as it is now, and after you changed the e-mail address, try
to decrypt some file. If that works, it should also decrypt the file that
unlocks your netbook.

It is wise to keep a copy of your key as it is now around just in case, anyway.
If you do something wrong, you can take the backup and start over.


I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
You can send me encrypted mail if you want some privacy.
