RIVYERA from SciEngines
The clever engineers at SciEngines now have an off-the-shelf computer, the RIVYERA S3-5000, that will crack DES in roughly one day. In the unlikely event that you're a hacker who needs to recover DES keys, this is definitely how you'll want to do it. A RIVYERA is roughly 20 times more cost-effective than the EFF's dot-com era DES Cracker.
These RIVYERA machines use 128 Xilinx XC3S5000 FPGAs to get the ability to test 292 billion DES keys per second. That's very impressive. I haven't been involved in building computers for a while, but unless things have changed a lot, it's probably still pretty much like Tracy Kidder describes in The Soul of a New Machine, although I have to wonder if engineers still quit their jobs from the stress of making faster computers, leaving behind only a note that says "I'm going to a commune in Vermont and will deal with no unit of time shorter than a season."
In any case, I'd love to hear the engineers at SciEngines tell the story of how the RIVYERA came to be.
To put things in perspective, however, even at the rate that a RIVYERA S3-5000 can crack DES, cracking a 3DES key will take essentially forever – roughly 200 trillion years. So I doubt that we'll see anything capable of cracking a 3DES key any time soon.
