Re: RSA over Rubiks Cube
This problably wouldn't be to cool a thing to do. A fella named Douglas Hopstader(?) wrote a book called Meta-Mathematics (same guy who wrote The Golden Knot). In this book he developed (or showed, forget who should get credit) an algorithm to solve Rubiks cube from any beginning state. It makes for interesting reading, but kills any attempt to use the cube as a cipher machine.

His name is Douglas Hofstader and the book is called "metamagical themas". He also wrote "Godel, Escher, Bach". -- Chris Kuethe <ckuethe@gpu.srv.ualberta.ca> LPGV Electronics and Controls <c100305@wolfcreek.cs.ualberta.ca> http://www.ualberta.ca/~ckuethe/ RSA in 2 lines of PERL lives at http://www.dcs.ex.ac.uk/~aba/rsa/ print pack"C*",split/\D+/,`echo "16iII*o\U@{$/=$z;[(pop,pop,unpack"H*",<> )]}\EsMsKsN0[lN*1lK[d2%Sa2/d0<X+d*lMLa^*lN%0]dsXx++lMlN/dsM0<J]dsJxp"|dc`
