MP5 on VAX

Willem Grooters — Fri, 10 Oct 2008 06:38:10 GMT

I'm looking for a program to caclculate a MP5 checksum - on VAX, VMS 7.1 CHECKSUM is considered insufficient.

Too bad you're not looking for something to run under VMS/VAX 7.3 - the older version 1.1B of HP SSL is available for that version, and can generate MD5 checksums.

HP SSL:
http://h71000.www7.hp.com/openvms/products/ssl/ssl.html

Generating MD5 checksums with OpenSSL:
http://64.223.189.234/node/992

That last page also points to an MD5 tool for VMS/VAX:
http://mvb.saic.com/freeware/freewarev80/md5/

but that version is probably also built for 7.3.

HTH,
Martin

Not sure if it can help, but here is the source code:

VAX image runs out-of-the-box on both 7.2 and 7.1.

Many of the core tools included on the OpenVMS Freeware distributions were very deliberately built using old OpenVMS VAX releases; OpenVMS VAX V5.5-2 was a pretty common build platform for these tools, and builds for a few key tools go back even further than that IIRC.

(I should scrounge up a V5.5-2 release kit for some stuff I'm working on now. But I digress.)

The following topic has some details on MD5, on building MD5 source code (from the RFC) specifically for OpenVMS VAX (there's a C compiler optimizer bug lurking here) and some general details on recent weaknesses identified in MD5:
