Create a new gpg key
--------------------

.. code::

   gpg --default-new-key-algo rsa4096 --gen-key


For me, it looked like:

.. code::

   gpg (GnuPG) 2.2.4; Copyright (C) 2017 Free Software Foundation, Inc.
   This is free software: you are free to change and redistribute it.
   There is NO WARRANTY, to the extent permitted by law.
   
   Note: Use "gpg --full-generate-key" for a full featured key generation dialog.
   
   GnuPG needs to construct a user ID to identify your key.
   
   Real name: Ahmad Nazir Raja
   Email address: ahmadnazir@gmail.com
   You selected this USER-ID:
       "Ahmad Nazir Raja <ahmadnazir@gmail.com>"
   
   Change (N)ame, (E)mail, or (O)kay/(Q)uit? O
   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.
   gpg: key E28E7DA5BE1BAEBF marked as ultimately trusted
   gpg: directory '~/.gnupg/openpgp-revocs.d' created
   gpg: revocation certificate stored as '~/.gnupg/openpgp-revocs.d/1F7BFED782E9E540432E3F48E28E7DA5BE1BAEBF.rev'
   public and secret key created and signed.
   
   Note that this key cannot be used for encryption.  You may want to use
   the command "--edit-key" to generate a subkey for this purpose.
   pub   rsa4096 2019-10-01 [SC] [expires: 2021-09-30]

How to upload it?

List all the keys:

.. code::

   gpg -K --keyid-format long --with-colons --with-fingerprint

Export the one that is called fpr (no idea what that means):

.. code::

   gpg --export -a 1F7BFED782E9E540432E3F48E28E7DA5BE1BAEBF

I uploaded my key in firebase. I couldn't use the command `gpg --keyserver certserver.pgp.com --send-key E28E7DA5BE1BAEBF`
