GNUPG HOW-TO


Run the following from a linux based operating system (e.g. debian) and accept the defaults.
Note, it may take some time to generate the random information. 

gpg --gen-key

To see all the keys - yours and your friends etc.: 

gpg --list-keys

Example of above: 

/home/you/.gnupg/pubring.gpg
----------------------------
pub 1024D/32j38dk2 2001-06-20 you <you@your-address.com>
sub 1024g/289sklj3 2001-06-20 [expires: 2002-11-14]


All the public keys you know are stored in the file:
~/.gnupg/pubring.gpg
pub = Public Key
Public Key ID (UID) = 32j38dk2

To send your key (public) to a person: 

-o is for a file name (steve)
-a is for an ascii file
gpg --export -o steve -a UID

To import a key manually from someone: 

gpg --import filename

Upload Public Key to key server: 

gpg --send-keys --keyserver wwwkeys.pgp.net UID


To edit keys - Typically used for signing keys
(cant change name or comment, only password and expiry)
UID = See example above 

gpg --edit-key UID

To Search for Keys:
(This Will also allow you to download and include the person) 

gpg --search-key --keyserver wwwkeys.pgp.net stephen burke

To Create a gpg fingerprint so you can PRINT out your Key fingerprint:
This allows you to take away to a "Key Signing Party" and sign other keys verifying the person's identity using two forms of id. 

gpg --fingerprint

Add User ID

Adding in a User ID: 

gpg --edit-key UID
uid n  //Toggles selection of user id with index n. Use 0 to deselect all. 
list

See the * beside the Current User id. After current ID is selected type: 

primary

That should be it. Upload keys with command above.
