How to list the keys in your public 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 > fingerprint.
Where do I put the private key in GPG?
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. 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!
How to encrypt a file with a public key?
Encryption/decryption commands. To encrypt a plaintext file with the recipient’s public key: gpg -e -r recipient_userid textfile. To sign a plaintext file with your secret key: gpg -s textfile. To sign a plaintext file with your secret key and have the output readable to people without running GPG first: gpg –clearsign textfile.
How to decrypt data in GPG with multiple secret keys?
To decrypt data, use: gpg -d mydata.tar.gpg If you have multiple secret keys, it’ll choose the correct one, or output an error if the correct one doesn’t exist. You’ll be prompted to enter your passphrase. Afterwards there will exist the file “mydata.tar”, and the encrypted “original,” mydata.tar.gpg.
