Thanks for the
advice. It is difficult to convince customers that dont want to believe that
their multi billion Rand systems are vulnerable and need to be
replaced.
South African
enterprises are very conservative and need hard evidence, especially when the
people holding the purse strings know nothing about crypto. It needs to be
proved to them that their system can be cracked (by actually cracking their
system).
Thanks
anyway

Subject: RE: Breaking single
DES
I don't think this is the appropriate list for discussing this topic
specifically. There are algorithms for optimizing DES breaking in
parallel across large register sets (like MMX for example), but I'm not sure
anyone has translated those into ready to run software. Crypto++ doesn't
have that level of optimization as it just isn't a focus of the
library.
If you have a customer who doesn't think DES is weak, even after reading the
literature out there, then maybe you should just start to berate their
intelligence. From the sounds of it, it may be your only avenue left.
(half J).

Subject: Breaking single DES
I work
for a company in South Africa which develops security solutions for the
financial (Banks, Mastercard, Visa etc.) and pre-payment(Cell -phone
payment etc.) industries. We are having significant difficluties in persuading
various clients that single DES based systems are not secure. While I could go
and buy a DES cracking machine (for under $1000) I was hoping that someone
would be able to enlighten me on any any PC based single DES cracking software
(distributed cracking software is great!). If anyone could help I would really
appreciate it.
