It is also possible to add a cryptographic digital signature to a message, so the message integrity and sender can be verified, if a particular correspondence relied upon has not been corrupted. They must always be exchanged carefully to prevent identity spoofing by corrupting public key ↔ 'owner' identity correspondences. The resulting public keys can be exchanged with other users in a variety of ways, such as Internet keyservers. GPG encrypts messages using asymmetric keypairs individually generated by GPG users. Cross compilation is not a trivial exercise, at least in part because security provisions vary with operating system and adapting to them is often tricky, but high quality compilers should routinely produce executables which will interoperate correctly with other GPG implementations.
GNU PRIVACY GUARD DEVELOPERS FOR MAC OS
For Mac OS X, there is a free port called MacGPG which has been adapted to use the OS X user interface and its native class definitions.

GPG can also be compiled for other platforms like Mac OS X and Windows. Note that, because the plugin mechanism is not part of GPG itself and not specified by the Open PGP standard, and because neither the GPG nor Open PGP developers were involved in their development, it is possible that GPG's security benefits could be compromised or even lost as a result of using such auxiliaries. A plugin known as Enigmail allows GPG to be integrated with Mozilla and Thunderbird, which works on Microsoft Windows as well as Linux and other operating systems.
For GNOME, there is a graphical GPG front-end called Seahorse. It is frequently included in free operating systems, such as FreeBSD, OpenBSD, and NetBSD and nearly all distributions of GNU/Linux.Īlthough the basic GPG program has a command line interface, there exist various front-ends that provide it with a graphical user interface for example, it has been integrated into KMail and Evolution, the graphical email clients found in the most popular Linux desktops KDE and GNOME. GPG is stable, production-quality software. The current stable version is 1.4.1, and the last development version (with S/MIME support) is 1.9.15. See both PGP and OpenPGP for more information. The German Federal Ministry of Economics and Technology has funded the documentation and the port to Microsoft Windows in 2000.īecause GPG is an OpenPGP standard compliant system, the history of OpenPGP is of importance. Version 1.0.0 was released on September 7th, 1999. GPG was initially developed by Werner Koch.
