------------------------

to import a public key:
gpg --import public.key
This adds the public key in the file "public.key" to your public key ring.

to import a private key:
gpg --allow-secret-key-import --import private.key
This adds the private key in the file "private.key" to your private key ring. There's a note (*) at the bottom explaining why you may want to do this.

to delete a public key (from your public key ring):
gpg --delete-key "User Name"This removes the public key from your public key ring.
NOTE! If there is a private key on your private key ring associated with this public key, you will get an error! You must delete your private key for this key pair from your private key ring first.

to delete an private key (a key on your private key ring):
gpg --delete-secret-key "User Name"This deletes the secret key from your secret key ring.

To list the keys in your public key ring:
gpg --list-keys

To list the keys in your secret key ring:
gpg --list-secret-keys

To generate a short list of numbers that you can use via an alternative method to verify a public key, use:
gpg --fingerprint > fingerprintThis creates the file fingerprint with your fingerprint info.
