# Generate a new pgp key: (better to use gpg2 instead of gpg in all below commands) | |

# maybe you need some random work in your OS to generate a key. so run this command: `find ./* /home/username -type d | xargs grep some_random_string > /dev/null` | |
# check current keys: | |
gpg --list-secret-keys --keyid-format LONG | |
# See your gpg public key: | |
gpg --armor --export YOUR_KEY_ID | |
# YOUR_KEY_ID is the hash in front of `sec` in previous command. (for example sec 4096R/234FAA343232333 => key id is: 234FAA343232333) |
