Have a look at the thread "hash function Shahaha". The OP, Rade,

proposed a hash function and described it by posting a short C

program. That description was immediately understandable and Rade is

getting some valuable feedback including examples of breaks in his

hash.

You do not post any short C programs. You post a great deal of

imprecise verbiage. If you want us to understand vector cryptography

then post a short C program. C++, Java or, in a pinch, Pascal/Delphi

will do as well.

You already understand Vector cryptography. Your job is to transfer

that understanding to us. You can best do this with a short C program

which will allow us to a) input a plaintext and a key giving the

cyphertext and b) input the cyphertext and the same key giving the

original plaintext back again. Use Rade's hash program as an example

if you want. His method obviously worked. Yours has not. I am sure

you are intelligent enough to learn from his example.

Unless your'e interested in Vector Cryptography for intellectual

reasons you should give it a miss and instead go for the "Spanning"

cryptography that I am promoting also. This cryptography is almost

embarrassing in its simplicity and is technically more efficient

(smaller ciphertext) than the other. It is very suitable for writing

in any of the languages that you are already proficient in. Spanning

cryptoraphy laughs at mathematics which appeals to me a lot. - the

algorithm is self evident from the download in this case also - I

can't do much more to facilitate readers than I have - I only deal in

unbreakable cryptography so either one of these is ok - Good luck with

whatever you decide - adacrypt
