## Create Key
Generate a new private/public key pair using ECC. It is a modern
standard that provides strong security and works well for radio use
due to smaller key sizes.
1. Create a primary key for signing using ECC. Replace FIRSTNAME,
LASTNAME, and EMAIL (keep the < and > characters).
gpg --quick-generate-key "FIRSTNAME LASTNAME <EMAIL>" ed25519 sign 0
2. List your keys and identify the fingerprint of your new key.
gpg --list-keys
3. Generate an encryption subkey. Replace FINGERPRINT.
gpg --quick-add-key FINGERPRINT cv25519 encrypt 0
4. List your keys again. You should now see a subkey that is suitable
for encryption (`[E]`).
gpg --list-keys
