Install the GNU Privacy Guard package in Debian as gnupg.
This is the GNU implementation of the OpenPGP.
To automatically check signatures from a keyserver add the name of a
keyserver to /home/kayon/.gnupg/gpg.conf file. For example
you may like to add the following, although it might be best to stick
with the Debian defaults:
keyserver wwwkeys.au.pgp.net
|
This replaces the command line option --keyserver wwwkeys.au.pgp.net.
To create a gpg key:
$ gpg --gen-key

We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.

To put your public key on to one of the public key servers (so others
can access it) you can do:
$ gpg --send-key --keyserver pgp.earth.li 5A829E4A
gpg: success sending to `pgp.earth.li' (status=200)
|
You can check the key was received with:
$ gpg --recv-key --keyserver pgp.earth.li 5A829E4A
gpg: key 5A829E4A: "Kayon Toga <[email protected]>" not changed
gpg: Total number processed: 1
gpg: unchanged: 1
|
The key is also now at other servers without any extra effort:
$ gpg --recv-key --keyserver wwwkeys.pgp.net 5A829E4A
gpg: key 5A829E4A: "Kayon Toga <[email protected]>" not changed
gpg: Total number processed: 1
