GnuPG or GPG
is the Gnu Privacy Guard: High Strength Encryption (1024 bit) for your System. THIS Set of Tools allows you to encrypt and sign your data and communication SECURELY
GnuPG itself is a command line tool without any graphical stuff. It is the real crypto engine which can be used directly from a command prompt, from shell scripts or by other programs. Therefore it can be considered as a backend for other applications.
However, even when used on the command line it provides all functionality needed - this includes an interactive menu system. The set of commands of this tool will always be a superset of those provided by any frontends.
- Full replacement of PGP.
- Does not use any patented algorithms.
- GPLed, written from scratch.
- Can be used as a filter program.
- Full OpenPGP implementation (see RFC4880 at RFC Editor ).
- Better functionality than PGP and some security enhancements over PGP 2.
- Decrypts and verifies PGP 5, 6 and 7 messages.
- Supports ElGamal, DSA, RSA, AES, 3DES, Blowfish, Twofish, CAST5, MD5, SHA-1, RIPE-MD-160 and TIGER.
- Easy implementation of new algorithms using extension modules.
- The User ID is forced to be in a standard format.
- Supports key and signature expiration dates.
- English, Danish, Dutch, Esperanto, Estonian, French, German, Japanese, Italian, Polish, Portuguese (Brazilian), Portuguese (Portuguese), Russian, Spanish, Swedish and Turkish language support.
- Online help system.
- Optional anonymous message receivers.
- Integrated support for HKP keyservers (wwwkeys.pgp.net).
- Clears signed patch files which can still be processed by patch.
- and many more things....
GnuPG works fine on GNU/Linux with x86, alpha, mips, sparc64, m68k or powerpc CPUs. (x86 is the primary development system, the other CPUs are only checked from time to time.)
It compiles okay on GNU/Hurd but because Mach has no random device, it should not be used for real work. Work is underway to add an random device.
FreeBSD with x86 CPU works fine.
There are pre-compiled packages for OpenBSD on: alpha amd64 arm hppa i386 m68k m88k powerpc sparc sparc64 vax. We're certain it works fine in i386, and suppose that on the others too.
NetBSD works fine (x86 CPU?).
Windows 95/98/NT/2000/ME/XP with x86 CPU works fine (you need a special setup to build it).
PocketConsole - a Windows NT-like console for the Pocket PC - is supported.
MacOS X is also supported; please see http://macgpg.sourceforge.net/ for detailed information.
