title: Getting PGP private key
body: <p>I would like to know how data encryption and decryption works in PGP. As part of encryption, "gpg --gen-key" is used to generate the keys, And I got a public key, however I am not sure how to get private key. does it store in a specific location? is there any command to generate? I don't have any clue.</p>
