GnuPG for VMS - A Public-Key Encryption/Decryption Utility

Excerpt from the GnuPG Web Page:

GnuPG is a complete and free implementation of the OpenPGP standard as defined by RFC4880 (also known as PGP). GnuPG allows to encrypt and sign your data and communication, features a versatile key management system as well as access modules for all kinds of public key directories. GnuPG, also known as GPG, is a command line tool with features for easy integration with other applications. A wealth of frontend applications and libraries are available.

GnuPG 1.4.23 VMS-Ready Kits

• VMS port notes (as included in the source-only and complete kits, below). This document describes the changes required to build GnuPG version 1.4.23 on VMS.

  /ftp/gnupg/gnupg-1_4_23a_vms/vms_notes.txt

• Source-only kit (about 6MB) including:
  • Source (original and modified).

  /ftp/gnupg/gnupg-1_4_23a_vms/gnupg-1_4_23a_src.zip

• Complete kit (about 19MB), including:
  • Source (original and modified).
  • Alpha objects and executables (built on VMS V8.4 with HP C V7.3-010).
  • IA64 objects and executables (built on VMS V8.4 with HP C V7.3-020).
  • VAX objects and executables (built on VMS V7.3 with Compaq C V6.4-005).

  /ftp/gnupg/gnupg-1_4_23a_vms/gnupg-1_4_23a_vms.zip

Note that support for extended file names on ODS5 file systems depends on relatively recent C RTL features, as found in VMS V7.3-2 or VMS V7.3-1 with VMS731_ACRTL V3.0.

The Zip archive for the complete kit was created using the Zip "-V" option to preserve the VMS file attributes, but the source files in these Zip archives should be usable on a non-VMS system.

Additional Notes for the GnuPG 1.4.23 Kits Above

• Few problems have been reported, but this product has not been well tested. Some caution would be prudent.

• user's default directory (SYS$LOGIN) does not exist. This should be corrected in a future release.

• Except for the mlock() code and some file size determination code, this work is generally independent of the previous HP-supplied GnuPG 1.4.7/1.2.4/1.2.3 kits. Among other things, this means that the VMS-specific "entropy gathering" code here is different, and may be better or worse than the older, HP-supplied code. (The code here, [.cipher]rndvms.c, spawns DCL commands, and processes the output, roughly like the non-/dev/random UNIX code in [.cipher]rndunix.c. This should make it easier to modify, if more suitable DCL commands can be found.) If the quality of the entropy gathered by this code is suspected of being insufficient, it should be possible to generate keys on a different host system type where this would not be a problem, and to import those keys into the keyrings on the VMS system.
