Hi.

  I've been trying to use a Blowfish Java implementation by Markus Hahn
( http://www-hze.rz.fht-esslingen.de/~tis5maha/software.html ) to
encrypt a small amount of data (less than 256 bytes) whith a 80 bit
secret key.
  The communication is made from a Applet to a Servlet using simmetric
encryptation.
  The info that I am trying to encrypt has a valid time of about two
monthes and it is _not_ too sesitive.

Problem:

  Even devius stealth methods are quite simple do declassify the applet
and gain access to the secret key or function to generate key see
http://www.awesome.com/declass.html (it's free!) for details.

 Does anyone has some clue on how to defeat this ?

Thanks,
Victor.
