Crypt::Blowfish_PP
|
|
==================
|
|
|
|
Blowfish is a published algorithm written by Bruce Schneier
|
|
(http://www.counterpane.com/). Unlike IDEA or DES etc. there are no patent
|
|
implications in using this algorithm.
|
|
|
|
It uses anywhere between a 64 bit and a 448 bit key. The transform itself is
|
|
fast and operates on a 64 bit block, and most of the calculation time is in
|
|
initialising the context with the key data.
|
|
|
|
The _PP name comes from the fact that this implementation is Pure Perl, and
|
|
will not have any compatibility problems.
|
|
|
|
I have not included any sort of multiblock structure in this implementation
|
|
(I might do in future), so to be useful you will probably need something
|
|
like Crypt::CBC. (v1.01 fixes the compatibility issues with Crypt::CBC)
|
|
|
|
This passes the test vectors on http://www.counterpane.com/vectors.txt
|
|
|
|
To install, untar the module
|
|
|
|
do the standard:
|
|
$ perl Makefile.PL
|
|
$ make
|
|
$ make test
|
|
# make install
|
|
|
|
This implementation is entirely object oriented, and entirely written in Perl.

PLEASE NOTE UPDATED EMAIL ADDRESS: mbm@colondot.net, as the other may stop
|
|
working at some point soon.
