Hi. Anybody know where I can pick up the source to dc? What about arbitrary precision math routines? What about RSA cyphering routines? I received a reply saying that I should get APML (arbitrary precision math library). I checked several locations, but was unable to find it. Anybody got an idea where I can find any of this? Thanks, Ralph gilgalad@dip.eecs.umich.edu gilgalad@zip.eecs.umich.edu gilgalad@caen.engin.umich.edu Ralph_Seguin@ub.cc.umich.edu gilgalad@sparky.eecs.umich.edu USER6TUN@UMICHUB.BITNET Ralph Seguin | In order to get infinitely many monkeys to type 565 South Zeeb Rd. | something that actually makes sense, you need to Ann Arbor, MI 48103 | have infinitely many monkey editors as well.

Last time you posted this query, I pointed out that bc was developed by AT&T, and is covered by AT&T's license agreements. Guess what -- the same is true for dc. I also pointed out that RSA is covered by a U.S. patent. At any rate, if you're looking for just the multiple precision arithmetic stuff, the following was posted to sci.crypt (to which I referred you) a couple of weeks ago: Kevin Coombes's "arith", ftp.math.lsa.umich.edu: pub/kevin/arith.tar.Z Henri Cohen's "pari", math.ucla.edu: pub/pari J Vuillemin et al's "bignum", email to librarian@decprl.dec.com Pari is copyrighted, but freely redistributable unmodified and in its entirety.
