Excuse me, but this post was about your perception that passwords were

stored on a system and your idea to obfuscate them to "solve" this

"problem".

Not necessarily so but the popular idea that they are stored is wrong

and programs that are so shallow to do so should be condemned. It's

nice to know agree but amongst the unwashed masses, their brains are

still in "park."

All it shows is that you do not understand properly implemented modern

cryptography which *does not* store a password but a non reversible hash

function and this makes your "problem" non-existent and your "solution"

to the problem totally useless.

To this you claimed that the hash function would give away the size of

the password, which also shows you do not understand cryptographic hash

functions, which normally put out a fixed sized hash. So, all the rest

you are now producing is worthless stuff to fix problems that only exist

in your mind caused by your lack of any understanding of cryptography.

Again, ignorance is predominate. Another means of doing something

useful should be considered and it is an aside that I also suggest

that nothing need be stored in most uses.
