If the "Secret Transformation" is badly chosen, it may destroy _all_ of
it ;-)
See Knuth's "super-random" generator I cited earlier.

That's the biggest hole I found in you dude. That shows you've no idea
AT ALL about the software and yet you argue like you've been using the
product for ages - resulting to confusions, senseless reasons, and a
merry go round discussion. I can't blame Vanessa if she feels that the
discussion is going nowhere let alone a waste of time as most people
in here are applying their treasured principles to a wrong item.

- To be honest with you lads, Nobody is forcing you to use the
unbreakable Infinite One-Time Pad but judging it without even using it
is undoubtedly WRONG! It's unbelievable! If you don't want to use it
because you're scared of trojan, spywares, etc. and you believe that
it's not worth a try then you have NO RIGHT to call it a BS, simply
get your a*se out of it and if you do want to call it a BS, you should
know its A-Z, use it,and produce a credible reason. People should be
careful in giving verdicts to a PARTICULAR item specially in a public
forum like this. If the name One Time Pad is the issue well, this
software is not the legendary One Time Pad, its the INFINITE One Time
Pad produced in 2009 using the latest technology!

I explained how GnuPG works in 3 simple paragraphs without having to ask
you to download and try it out. If you can't do the same with IOTP, then
that's a clear sign of a ill-devised cryptographic software.

This thread as been the telephonic equivalent of:

john - "look at these nice TalkThing2000 that you can connect with a
wire to a central and talk with other people. You just mark their number
and you listen on the listening thing. This is the best thing since
sliced bread! The company the sells them say they are great!"

sci.crypt - "err... did you ear about cell phones?"

john - "cell phones are a thing of the past. you need to recharge them
in order for them to work! you must get in sync with the latest advances"

sci.crypt - "you can carry cell phones with you, and you can't carry
local line phones"

john - "dude, how can you say bad things about TalkThing2000 without
even trying them out?"

sci.crypt - "err... ok, I give up.... :("

- That's a very nice example dude, I like it - funny that... however,
it is so simple enought to match the complex situation we're in that's
the reason why confusion is all around us at the moment and the
discussion is just goin' nowhere. In engineering works, you don't stay
in the office all the time, you need to go out, get into the machines/
equipment, make thorough examination to produce accurate data. There
are things that written description (+imagination) is not just enough
to thoroughly understand them (esp. processes) yet you can easily
understand them (processes) when you actually see them in action.

Let me put this another way: _you_ say that IOTP is very secure. To be
able to say something like that _you_ must know exactly how it works.

If you don't know how it works, you can not argue that it is secure. If
you do know, then you can explain to us why it is secure without us
having to go and try it out.
