Revolution has a base converter function baseConvert().  It takes a 
numeral (string of bits or digits or whatever) in a base an puts it 
into a 32-bit value.  It then takes that 32-bit value and converts that 
to a numeral in the second base.  You can get a negative number as a 
result if the msb of the 32-bit value is 1 so there is some indication 
that the 32-bit value is signed, but I don't think that is consistent.

Which reminds me.  Are you supposed to have all those signed numbers in 
Blowfish?

Well, fortunately there are no bit-shifts in Blowfish, just figuring 
out how to think 4 chars and 32-bit numbers.
