GPG stands for GNU Privacy Guard.
GNU Privacy Guard (GPG) is a free software implementation of the OpenPGP standard. It's often used for encrypting and signing data and communications, ensuring privacy and verifying the authenticity of messages. Essentially, it allows you to:
- Encrypt: Scramble data so that only the intended recipient can read it.
- Sign: Attach a digital signature to a message, verifying that it comes from you and hasn't been tampered with.
GPG is an independent implementation of Pretty Good Privacy (PGP) but based on open standards. It provides a command-line interface, and various tools and graphical front-ends are available for easier use. It's a crucial tool for anyone concerned about data security and privacy in the digital age.
