GnuPG works very well on almost all 32 and 64 bit platforms.

It works fine on GNU/Linux with amd64, x86, alpha, mips, sparc64, armhf, arm64, m68k, or PowerPC CPUs. (amd64 is the primary development system, the other CPUs are only checked from time to time.)

64 bit versions of Windows 10 and 11 are very well supported.

MacOS X is also supported; please see gpgtools.org for detailed information.

OpenBSD, FreeBSD, NetBSD, AIX, and Solaris are fully supported.

The information in this section is considered outdated!

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.

A port of GnuPG to VMS is available at http://antinode.info/dec/sw/gnupg.html.

GnuPG compiles and runs on many more systems, but due to the lack of a well tested entropy source, it should be used with some caution. We have positive reports on these systems:

• BSDI v4.0.1 with i386
• HPUX v9.x, v10.x and v11.0 with HPPA CPU
• IRIX v6.3 with MIPS R10000 CPU
• MP-RAS v3.02
• OSF1 V4.0 with Alpha CPU
• OS/2 version 2
• SCO UnixWare/7.1.0
• SunOS on Sparc and x86
• USL Unixware v1.1.2
