My experience of Ada runs to developing the sourcecode of these ciphers into a design proof of a working program only in each case - I am not interested in the Ada-95 programming language per se for any other reason - in theory at least, programs written in earlier compilers should run in the current updated revised Ada - 2005 programming language also but without testing that theory I prefer not to take any chance on it backfiring - also the Gnat 311.p compiler is one that came with the text book I used may years ago and I became kind of attached to it. - I reason that if any body is interested in developing this cryptography any further it would not be expecting too much for that person to test out my Ada-95 programs in the new environment of Ada-2005 and tweak the sourcecode if needs be to suit the new compiler should it need some user asistance. Note: The earlier version of Ada i.e. Ada-95 does not have built-in means of doing vector algebra like the crossproduct etc and the user was sensibly expected to use longhand methods on the operands which I agree with and prefer but there was such an outcry for built in packages that would do the operations of vector methods as packages on call as sourcecode from users that it was included when the language was updated in the Ada-2005 revised compiler. For all round safety and simplicity's sake therefore I decided to include a compiler in the download rather than refer people to a source where it could be found - also I think that version i.e. Gnat 311.p is no longer available now as far as I know. - I am willing to cooperate with you if you are on the level - adacrypt If you are on the level about evaluating these ciphers then please note that there are three versions to each cipher - Mark_0 is a long fully expanded tutorial/diagnostic version that is meant to be useful in displaying all of the interanl workings of the program in question - the throughput rate is not meaningful. Mark_1 and Mark_2 are identical and are devoid of any display of how they work which of course is exactly the same as Mark_0, the time taken as the encryption or decryption rate is then meaningful in tests. The onboard test files are named according to the number of characters (nominally) that they contain e.g PlainTextFile_1.dat contains only 1 character (Capital P), PlainTextFile_9.dat contains 9 characters (the word 'milestone') The design focus is on the cryptostrength of these ciphers on the basis that once theoretically unbreakable strength is realised in the algorithm then the rest (whatever it may be ) is either computer science or management orientated and is achievable more easily by well known methods. Vector cryptography is very elegant but the scalar cipher on the table with it has the same theoretically unbreakable crypto strength but is much, much more efficient - this is being made available also later as a download to interested parties.

GNU/Linux distributions will often have compilers for C, C++ and suitable things (whatever you want to call them) for executing Python, Perl, Awk, etc. (Java's a slightly special case in that often the GNU java compiler will be installed but usually one wants the Oracle (formerly Sun) implementations.) Not for the Ada language, though---there's no technical difficulty, it's just that almost nobody wants it so it's not appropriate to install it by default. |
