Hashclash

[Heyoka]

Hello everyone!

I think everybody has been waiting for this project update.
Our server has caught up now with almost all results and I have updated the collisions page.
There are still some results in progress and they will be finished soon.
However, we will not continue with our birthday search since we feel we are ready for stage 2.

We have chosen one of the useful collisions with 8 remaining bitdifferences.
And in stage 2 we will cancel these 8 bitdifferences one by one, so that we will end with no differences and thus a full MD5 collision!!
For each of those bitdifferences we will have to go through the following two steps:


    * Creating a differential path:
      this is a precise description of how differences should pass through MD5 such that one bitdifference will be cancelled;
    * Finding a matching message block:
      find a real message block that satisfies this differential path.



Step 1 is something that is far easier to control on a simple cluster, and we are almost finished with this step for our first bitdifference.
For step 2 we really can use your help!

We will need some time to finish step 1 and start step 2. But until then there are plenty of other BOINC projects for which you can crunch while you wait. BOINC is very well capable of doing work for more than one project.
So there is no need to wait or to disconnect from HashClash.
Your help is really appreciated here!

As a final note I want to add that I always try to quickly respond to questions etc., however I am really busy with finishing my studies and writing my thesis. Project HashClash was part of my thesis and I will continue HashClash between everything else.
