Re: Attack on DES paper and CRACK

I want to thank everyone that helped me on these.

I got it 'locally' over at Mich State U.  Our security manager was so
pleased with the information in it, that he intends in including the whole
piece as an addendum to a security review paper for the auditors and senior
management (rather than just referencing it).

It was quite an eye opener for him, particularly the appendix on the chip
desire for the DES search chip. :)

I got CRACKERJACK, and once I did, I did not give it to the original
requester, rather to our security people for a tool for them.  Too
dangerous, I can't trust that person to restrict who gets it.

However, I was told:

But the response on ftp.uu.net is terrible.  I have not found these.  Can
anyone point me to another source of these?
