From the command line:
Run gpg --list-keys 'your name'
to list the keys you currently have (replacing your name
with the name you have while setting up):
$ gpg --list-keys muru
/home/muru/.gnupg/pubring.gpg
--------------------------------
pub 2048R/AD0CC9B4 2015-07-15
uid muru
sub 2048R/450DAD90 2015-07-15
Note the fingerprint of the key you want to export. The fingerprint of my public key is AD0CC9B4
. To export it, I'll do gpg --export
(-a
is for ASCII armour, so that the key is in the usual base64-encoded form):
$ gpg -a --export AD0CC9B4

You can redirect the output to a file:
gpg -a --export AD0CC9B4 > my-pubkey.asc
Then my-pubkey.asc
should contain your ASCII-armoured public key.
The corresponding private key can be exported with:
gpg -a --export-secret-keys AD0CC9B4
The output of this command will begin with
-----BEGIN PGP PRIVATE KEY BLOCK-----
