Blowfish is a published algorithm written by Bruce Schneier
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.
