1. create a key (choose RSA with 4096):

gpg --full-generate-key

2. share the public key with:

gpg --armor --export > public-key.asc

3. upload to some keyservers, such as ubuntu or MIT:

gpg --send-keys --keyserver keyserver.ubuntu.com KEYID
gpg --keyserver hkp://pgp.mit.edu --send-key KEYID

4. backup the private key:

gpg --export-secret-keys --armor KEYID > priv.asc

5. list your keys:

gpg --list-keys
gpg --list-secret-keys

6. clean up if needed:

gpg --delete-secret-key KEYID
gpg --delete-key KEYID

7. finally, you should upload your key into official servers such as ubuntu or mit.
