[Gambas-user] Need to have blowfish en- and decryption

[Daniel Oxley]

I tried about 4 or 5 times in the end to rewrite this in Gambas.  Each time
I gave up and just binned the lot.  Maths was never my strong point!
You are right that it would be easier to just dump this code and write a new
version from scratch.

You can get a break down of how it works from Bruce Schneier's website.  Who
knows, maybe he would even be interested in helping....???  He once said
that the more languages his algorithm is translated into the better.

I think the best reason to use Twofish is that it is unpatented and open.
You know exactly how it works.  AFAIK, it has not been cracked (yet?)
either.

Hey Daniel:

I have had a hard time of making out the vb source code for twofish...  
(head reels from all the math formulas I've seen from reading up on 
it...)... 

 From what I've been able to decipher myself...  It'd be just as easy to 
write our own from scratch, unless there is some particular reason to 
use twofish...

Let me know what you think!
