(newbie here) I try to analyze amateur cryptosystem and wondering, if it's possible to reduce it as reduce a very long boolean expression? What tool can I try to use?

I just want to know, if it's reducible, because if it would be possible to reduce it significally, that would be a very optimistic sign. Is impossibility of reducibility is a measure of good cryptosystem? –  Dennis Yurichev May 15 '12 at 5:47
    
Sorry, it is not really clear what you are asking. Do you search a tool for reducing boolean expressions? Do you search a solver? (See our algebraic-attack tag for some questions about this.) Feel free to edit this question to be more clear, and then flag is for moderator attention, and we can reopen it. –  Paŭlo Ebermann May 16 '12 at 22:50

A known plaintext attack on a cryptosystem can often be expressed in the formalism of boolean satisfiability, then if the cryptosystem is weak solved using a solver program such as these ones.
