Re: Question about Blowfish


You might want to look up so-called "nothing up my sleve numbers"..

In Blowfish, initially the P-array and four S-boxes are the hexadecimal
digits of pi (discarding the initial 3).

Instead of pi, could the hexadecimal digits of any irrational number
(e.g. the base of natural logarithms, the square roots of 2 or 3), be
used in the P-array and the four S-boxes? Or is there some internal
design quality that would make Blowfish a weaker algorithm unless pi is
used?

Thank-you for any information for this extraneous question.
