GNU Privacy Guard

GNU Privacy Guard (GPG) is a free software tool that helps protect your digital communications and files. It uses encryption, a process that encodes information so only authorized people can access it. GPG employs a system called public-key cryptography, where you have a pair of keys: a public key (shared with others) for encrypting messages and a private key (kept secret) for decrypting them. This ensures your messages stay confidential and authentic, preventing unauthorized access or tampering. GPG is widely used for securing emails, files, and verifying digital signatures, making digital communication safer and more trustworthy.
