Seahorse should automatically recognize the key if it's in the ~/.gnupg directory. If not, I suppose you could try using the command line

Hmm. I use Enigmail with Thunderbird all the time, and I am on 64 bit Lucid (I am assuming the versions in the repos are 64 bit).
What app is best to use for the management of GPG keys in 10.04, I would use enigmail but it is not compatible with the latest 64bit thunderbird in the repos and therefore have to use evolution.
