Hal, I liked your description of Brans Cash. I'd like to turn your description into psudo-code or Perl whichever comes first and you are more comfortable with reviewing. Anyone lese interested in developing a bit of perl as an example of Brands cash in action? -Rick

Anyone lese interested in developing a bit of perl as an >example of Brands cash in action? Unfortunately, I don't think perl is suitable, as it has no facilities for multiprecision arithmetic. I was talking to Henry Strickland at Crypto and he is working on a package that would use the scripting language tcl (which is a little similar to perl) and could do this stuff. Alternatively you could use a public-domain package like gmp or perhaps the pgptools library created by Pr0duct Cypher. That last one has MD5 hash built in so it would have everything you need. For that you would have to program in C or perhaps C++ though. Hal

There is some multiprecision arithmetic in perl, but it's implemented as user-level functions, not as a builtin feature. Look at the bigint.pl, bigrat.pl and bigfloat.pl packages supplied with perl4. --apb (Alan Barrett)
