1. In your gpg.conf, you can specify a "digest-algo SHA256" which will set your default signature algorithm. The preferences in your key are used by others to determine which algorithms to use when sending messages to you. Not the other way around.
2. Your key ID will be a number (e.g. CD55 18C7) not your name. If the name you indicate matches more than one key, the first is assumed. The only way to exactly specify a key is by its (relativetly) unique key ID. I'm not sure if this answers your question. Here is another answer to your question with a different interpretation: If you have a key with multiple UID's and you want to change your primary UID, select the UID using "UID #" and then use the "primary" command from within the "--edit-key" menu. -- PGP Fingerprint: C54A C9DD 84AD C6FC D343 67C4 5195 D63A CD55 18C7 On Friday, June 22, 2007, at 08:47AM, "Andrew Berg" <[EMAIL PROTECTED]> wrote: >-----BEGIN PGP SIGNED MESSAGE----- >Hash: RIPEMD160 > >1.
