Pretty Good Privacy (PGP) provides data encryption and decryption for communication data such as texts, emails, directories, and files. It uses a algorithmic combination of hashing, data compression, symmetric-key cryptography, and public-key cryptography to sign, encrypt, and decrypt messages using a combination of private and public cryptographic keys.

This tutorial provides step-by-step instructions on how to generate private and public PGP keys using the key generator tool GPG4Win. You can use any key generator tool to create, decrypt, and encrypt messages; however, the GPG4Win application is free and easy to install.
