Yes, you are using a key *pair* in PGP that wasn't created in PGP. So PGP assumes that it is not trustworthy. You can do several things: 1) This is what I would do: Open the properties of the (GnuPG) key in PGP and activate "Implicit trust". That should make the key valid and automatically set its "Trust" value to maximum. "Implicit trust" is activated automatically for every key pair you generate in PGP, but not for imported keys. 2) Or you could also: Sign your (GnuPG created) key with another private key which belongs to you and which you trust fully (preferably one that was reated in PGP). Again, this will validate your (GnuPG) key and you can manually adjust the "Trust" value to whatever you wish. -- Regards, Lars ____________________________________________________________
