Finding MD5 Collisions With Chinese Lottery

Stanislav Shalunov writes "Jean-Luc Cooke posted a Usenet article describing a distributed webpage-based effort (Chinese Lottery) to find a collision in the MD5 function. All you need to do to participate in the effort is visit the URL that loads the code. The author comments: 'What is interesting about this approach - when we reach final release stage - is that any website that adds this small snippet of code to their pages will have their visitors working on the problem for the duration of their visit to the site'."

From the link:

You run an Applet, it reports to us the search results. Distributed computing without installing anything...and without people knowing you're stealing their idle CPU time. ;)

I don't know about you but I wouldn't lean out the window with the fact that I'm stealing from others.

Idle CPU time might be unused but I still want to know what my box is doing and why.

I wonder if the good slashdot people would be willing to make this into a slashbox ?

While I completely agree with your sentiment about being upfront... I don't agree with calling it "stealing".

Who clicked on the link?

Who has Java enabled on their browser?

Who has cookies enabled on their browser?

It isn't like he is doing anything "tricky" or using some "bug" to pull this off. The page doesn't "trap" you. It doesn't eat your CPU and make it impossible to quit the app or go to another page. And, for me, it didn't crash anything.

I *really* don't understand how this can even remotely be considered stealing. Every single item is being used *as*designed* both by the web author and you.

The way I see it... someone jumped in a pool... and now they are bitching about your clothes being wet?
