View source for GPG:Export

Once you have a GnuPG key pair, you will most likely want to export your public key. 

 $ gpg --list-keys
 pub   1024D/7482556C 2004-08-26 [expired: 2005-08-26]
 uid   Yasholomew Yashinski (When you send mail, do you use a postcard or envelope?)  <yashy@mail.yashy.com>

I can see here my key that I want to export, so I would do

 $ gpg --export 7482556C -a -o yashy.asc

Where -a means ascii encoded, and -o is what you want the output file to be called. Now I can upload yashy.asc to my favourite public [[keyserver]] or send to my friend(s) that want to to communicate with.
