Hi Francesco,

Welcome! No need to apologize! We're all pretty friendly here. :)

Excellent.

You can add "--armor" (or "--armour", I had no idea that GnuPG
supported the British spelling of the word. Interesting!) to
essentially any command that involves data being output. For
consistency I will use the spelling without the "u", but both are
equivalent.

For example, if you created a key with the KeyID of "KEYID", you could
export the public key for it to the terminal using "gpg --export
--armor KEYID".

If you wish to export the public key to a text file which you can then
include in an email, post on the web, etc., you could use "gpg
--export --armor KEYID > filename.txt" where 'filename' is whatever
you wish the file to be called.

The armor feature is indeed quite useful, but it comes at a slight
cost: armored files/messages are slightly larger than their unarmored,
binary counterparts.
