Ada and cryptography

Ada and cryptography

[Tuomas P]

Hi all!

Is (can?) Ada being used in cryptographic applications? If it is,
could someone point me out to webpages that have cryptographic code in
Ada?

I have been reading Markus Kuhn's article on Ada95 ("Information for
New Ada95 Programmers") and I have the impression that Ada might do
well in that area (too!).

Thanks for your time.

The LMD/KP encryption key generation, protection and maintenence system 
that the US armed forces use was written in Ada. You can't exactly 
download its sources over the web though. :-)

I believe there are litterally thousands of these systems being used 
"out in the field" (more likely, in the mountains) right now.

You can find some at

I could not find the original article so I'm responding to this one

Ada is in fact very well-suited for cryptograph, especially symetric, 
crypto, as most of the data types and operators needed can be defined or
are buldt in. For public-key crypto, bignumber libraries are missing,
but so are they doing in C, wich is considerd the "standard" language of 
cryptography.

I have implemented the serpent algorithm in Ada myself:

ftp://ftp.ii.uib.no/pub/ada/serpent.tar.gz

Otherwise, the links to some of the crypto code I have used earlier seems
to be dead, which is sad.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going
to land, and it could be dangerous sitting under them as they fly
overhead. (from RFC 1925)

Yes, it is.  Read http://www.sparkada.com/downloads/ieeesw.pdf for
an example.

Yes it can. I'm trying to implement some cryptographic algorithms in
Ada95 and you can see that work in:

http://sourceforge.net/projects/adacf

I'm afraid I couldn't dedicate enough time to complete the work. What
you can find there is an implementation of some of the most important
cryptographic hash (message digest) algorithms (MD2, MD4, MD5, SHA-1,
RIPEMD-128, RIPEMD-160, TIGER, and HAVAL) and the test vectors for
these algorithms.

I'm currently working on a multiprecission natural number arithmetic
package, cryptographic pseudorandom number generators (BBS) and some
of the most important symmetric key ciphers (DES, 3-Way, Blowfish, and
others). If you want the source code I could send you but be aware
that is not production quality code (at least not yet).

I was unable to get code from that link. The following might do better:

ftp://ftp.ii.uib.no/pub/ada/serpent.tar.gz
