  3. GPG Encrypt a File in Windows. As part of a recent project I needed to encrypt a file with GPG using a public key provided by a client before transferring it over to them. This seemed to be surprisingly badly documented (though this blog did come in handy) so I figured I'd document it as well as possible for future re-use
  4. GnuPG does not support encrypting to a recipient specified by a key file. The key must be imported in advance, and the recipient defined with either his mail address or key ID. I'd recommend to use a cleaner approach as expected by GnuPG and hard-code either the key's fingerprint, or a user ID given by that key and import it as usual

Likewise, GPG can do the same for files. If you wish to encrypt a file for someone else, you would use his or her public key to encrypt the file. However, if you wished to keep your own files. GPG (Gnu Privacy Guard) is an Open source implementation of Open PGP (Pretty Good Privacy) asymmetric encryption protocol. It generates a key pair of Public and Private keys to encrypt and decrypt your files. Public keys are generally used to encrypt file and they cannot decrypt. On the other hand, Private keys can only decrypt encrypted files
