I have seen this puzzle in the past, and if no one have solved It in the past 4 years I don't think It have an easy solution, or from my point of view doesn't even worth to try It. But if you believe that you can find the solution with brute force then good luck, the prizes is good but the solution is complex.

I really would love to see some one solving It, let's see who is the lucky user who get the full prize.

I am still working on it.
And by that I mean still trying to brute force the words I posted above, ofc.  

But yes, would be glad to have some more info on this.
