Official Best64 Challenge Thread

[frekvent]

I have experienced the same issue as described phish (but the original post seems to be deleted). I tried to simplify rules by doing some simple substitutions:

• sXY@Y -> @X@Y
  
• iNX@X -> @X
  
• ^X@X -> @X
  
• $X@X -> @X
  

But somehow this makes the rules less effective. For example, take the rules i42@2 and @2. They should be identical but they're not. When I test them separately against the phpbb hashes, i42@2 gives me 7520 hits but @2 gives me only 264.

Oh and thanks to atom for compiling the new best64.rule! I have tested it against some random hashes with some random wordlists and got some very good results! I did spot a minor simplification you could do. It turns out that "}}D1{" can be simplified to a single "]".

Anyway thanks a lot! It is truly amazing how much the original rules could be improved upon!
