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.
