What is the difference between PGP and GPG?
gpg vs pgp and OpenPGP OpenPGP is the IETF-approved standard that defines encryption technology that uses processes that are interoperable with PGP. pgp is Symantec’s proprietary encryption solution. gpg adheres to the OpenPGP standard and provides an interface that allows users to easily encrypt their files.
How do I find someone’s public key?

What is GPG secret key?
GnuPG is a tool for secure communication. … GnuPG uses public-key cryptography so that users may communicate securely. In a public-key system, each user has a pair of keys consisting of a private key and a public key. A user’s private key is kept secret; it need never be revealed.
