Re: A89: Re: Re: PR Hit -- Those bastards




There is a company in virgina I think it's mentioned on the rsa.com page
that has the worlds largest collection of supercomputers. The 64 bit rsa
competition had been going on for two years nationwide with the web
site support (As in. Everyone on earth who d/l's it works together noone
repeats the same key) and  it was not cracked. This company hooked
up their computers and cracked it in 17 minutes. If we could ask them to
put a little effort into it their computers are problebly updated by now
they
are afterall million dollar sgi's. I think their network pulls several
dousen
TFlops. They could problebly get it in under a day.
