PGP stands for Pretty Good Privacy, and OpenPGP is standard RFC 4880. PGP is a convenient suite for encrypting text, files, directories, and disks. All the principles are the same as discussed in the previous section with SSL and TLS key/certificates. The encrypting, signing, and verification are all the same. Go provides an OpenPGP package.
