From: Austin Obyrne Injection-Date: Sun, 30 Nov 2014 12:10:26 +0000 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Xref: news.eternal-september.org comp.lang.ada:23793 Date: 2014-11-30T04:10:26-08:00 List-Id: I have been experimenting in the last few days with a new version of some v= ector cryptography that I invented some years ago. The particular cipher computer program I am referring to is written in Ada-= 95 for MS Windows XP Vista 7 & 8 (*runs on hand held tablets MS Surface Pro= 2 & 3) My normal test programs that I use as test/tutorials are named PlainTextFil= e_1.dat increasing in sizes 9,100, 500,1000,2000,4000,10000, 30000 where th= e size of the file is that number of ASCII plaintext characters for encrypt= ion in that test file. For good measure I decided to add another file of 50000 characters in this = new version under test but where to find a ready-made suitable test file of= that size was my problem - keying in a file from scratch was just too time= - consuming. I looked around and found I had a file of Ada-95 source code= in my computer and decided to use that. I want to report what happened next in case it might be useful to programme= rs of Ada. The file of 49471 Ada sourcecode characters encrypted and decrypted perfect= ly which I knew it would anyway so I decided next I would test the fidelity= (a privately coined word that I think is apt but is not normal crypto jarg= on just for your info) of the entire experiment in cryptology by test-runni= ng the decrypted source code as (message-text now) in my Ada-Gide editor - = it compiled and ran perfectly without any editing and immediately encrypted= some test programs itself. =20 I am very pleased with this result for obvious reasons - compiling first ti= me round in an Ada compiler must be the most stringent test of unadulterate= d transport imaginable. The reason I am posting this article is to make these points :- *1) Programmers of any language may remotely post their stuff verbatim to o= thers with impunity using Ada as the carrier. *2) Cryptographers may use Ada to send encrypted ciphers to others verbatim= and know that they will work - there is no more secure method of secure tr= ansport and they will only need to periodically update the keys (which may = be public or encrypted as preferred, periodically) the initial delivery of = the mutual database must be made in a one-off secure courier delivery of co= urse. I hope it is in order for me to post a crypto article here bearing in mind = that you guys are in a programming language usenet. The host cipher is on offer to all. Regards to all, Adacrypt.
