Looking at your key, if you are expecting to encrypt messages to your friend, 
it would be best for you both to sign each other's keys. GnuPG will complain 
if you ask it to encrypt to an untrusted key and you can't build that trust 
until you get your key signed with his and his with yours. This keysigning is 
different to signing email or encrypting messages - there's plenty of 
documentation on keysigning at and

Try using 'gpg --list-sigs' on some of the keys already in your keyring - 
including those imported to verify signed emails on this list - to see how 
these key signatures show up. Make sure you read about keysigning before 
jumping in - e.g. please don't sign any key without personally verifying it. 
You should be able to verify your friend's key by contacting him by 
phone/post to verify the fingerprint of his key. 'gpg --fingerprint'. Other 
keys can be verified at Linux User Group meetings, OpenPGP meetings, 
exhibitions or other events.
