gnupg@1.4 for Mac

GnuPG is a set of encryption and signing tools that implement the OpenPGP standard, commonly referred to as GPG. It is mainly used to protect the privacy of email, verify the origin of files, and generate and verify digital signatures for data such as software packages. For users who need to handle sensitive information and want to ensure that communications cannot be read or tampered with by third parties, it provides a mature and reliable encryption solution. Because it is used via the command line, it is better suited to users with some technical background who are willing to complete key management, file encryption and decryption, and signature verification through terminal operations, and it is relatively common among developers, system administrators, and security enthusiasts.
