Minimalist implementation of the Blowfish algorithm in
pure Python -- slow, but useful for understanding the
algorithm, learning Python, crypto concepts -- no
warranties or guarentees of any kind. Not suitable
for governmental or commerical purposes.
First shared on the web: November 27, 2000
Last modified: Jun 17, 2001: streamlined by adding
un/hexlify from binascii, eliminated
unnecessary base conversions
Modified: Dec 8, 2000 (added file i/o)
Uses some syntax conventions unique to Python 2.0 but
these are easily removed for older versions of Python
