Wrapper for the Blowfish encryption algorithm
=============================================

  Rev 0.11: Fixes Feb 2003, by Uwe Koloska
  Rev 0.10: Initial release


This package defines a "blowfish" command which can be called in 2 ways:

    set coded [blowfish encode plain key]
    	# encrypt data with key

    set plain [blowfish decode coded key]
    	# decrypt data with key

Data is treated as binary, meaning that all input and output is going to
be converted and treated as byte arrays in Tcl.

An idea: if you need solid encryption in your own application, store the
key in C, and have CriTcl compile it - this makes it harder to extract.
