I have written a patch for John the Ripper http://www.openwall.com/john/ to allow cracking OpenVMS (Vax and Alpha) passwords. The patch is based on code from Shawn Clifford, Davide Casale and Mario Ambrogetti.
The sources are in http://jl.gailly.net/security/john-VMS-patch.tar.gz A README file is at http://gailly.net/security/john-VMS-readme.html or in ascii at http://jl.gailly.net/security/README.VMS This patch has been tested on x86 only and does not work yet on big endian systems. It uses asm code for speed but a portable C version is included as well. The asm version checks about 150,000 passwords per second on a 1 GHz system. Password cracking is much easier on OpenVMS than on other systems since passwords are not case sensitive and limited to alphanumeric, '$' and '_' only. Jean-loup Gailly http://gailly.net/security/
