Zebedee would not have been possible without the use of a large amount of freely-available software to do all the really hard stuff. I gratefully acknowledge the contributions made by the authors of the following software packages: Zebedee uses the "Blowfish" encryption algorithm devised by Bruce Schneier.

Julian Seward, Cambridge, UK. jseward@acm.org bzip2/libbzip2 version 1.0 of 21 March 2000 By default Zebedee is built using an aribtrary precision integer arithmetic library derived from the sources to mirrordir-0.10.49 which in turn derived this from the Python sources. The copyright is as follows: huge-number.c: arbitrary precision integer library from Python sources. This has nothing to do with cryptography.

This file was taken from the Python source for `long' type integers. I have changed it to compile independently of the Python source, and added the optimisation that GNU C can use 31 bit digits instead of Python's 15 bit.
