Welcome
This presentation of displacement cryptography here is intended to show the condensed results of the development work that has been ongoing on a companion site called, http://www.adacrypt.com for about ten years in a more concise form.

That site will continue to coexist independently under that same name in future also.


The Ada-95 programs on offer here as downloads are not claimed to be a fine piece of software engineering – I leave that to other experts.


I can stand over the mathematics and the cryptography however that comprise these ciphers and have no compunction in saying that this side of what you see is perfect.


The reader is asked to see this presentation of displacement ciphers as a more expanded ‘academic’ version of what the eventual minimalised work cipher will be.


Should this cryptography be adopted by some big operator I would expected a complete re-write of the program sourcecode in a form that would be more to their liking than mine I expect but that is how the real world has to be.


I can be contacted by any reader on: austin.obyrne@hotmail.com
