gpg: how to add a public key into keyring for gnome/evolution

[Dario Lesca]

Hi, how to add (into keyring?) a public key for verify mail signature
into Gnome/evolution ?

KDE have 'kgpg', what is the utility for Gnome?

I have install gnome-keyring-manager but I have not found a function for
do that.

Thanks
