GnuPG2

GnuPG2 (Gnu Privacy Guard version 2) is a free software tool that helps you keep digital communication secure. It allows you to encrypt your emails and files so only authorized recipients can read them, and to sign messages to prove they really came from you. It uses complex cryptographic methods to protect your data’s privacy and authenticity. GnuPG2 works with a system called Public Key Infrastructure, where you have a pair of keys—one public, shared with others, and one private, kept secret. This ensures your information remains confidential and verifiable in digital exchanges.
