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.
