Free cryptographic library for Ada?

Free cryptographic library for Ada?

[Peter C. Chapin]

Hello!

I am designing a security sensitive application and I would like to use 
Ada to develop it. This is something of a hobby project so it is very 
low budget. In my application I need to make secure hashes and digital 
signatures along with the necessary key management that implies. I'm 
looking for a free (GPL or similar license) crypto library written 
entirely in Ada. I don't particularly want to link to a C library since 
part of the point of using Ada in this case is specifically to avoid C.

Does such a library exist? I've been prowling around on the 'net but so 
far the projects I've turned up are very incomplete and inactive 
looking.

TIA

Peter

I have a blowfish implementation that I created from the reference
implementation and documents.
There is also an MD5 package out there (with some small bugs) that I have
fixed.

So, I guess the short answer is I don't know of a full library..But if you
are interested in a partially
tested blowfish and MD5 package let me know.

Okay, thanks for the information. The real sticking point for me appears 
to be digital signatures.

Cristoph Grein also has an MD5, and so do I since I was unaware of
either Cristoph Grein's or your efforts until I had completed :-)

I got stuck in version skew hell for a while.  I needed to update to 
GNAT 3.15p to compile one of the libraries I wanted to use.  In the 
process I discovered a lot of my common tools needed to be modified for 
newer versions of various tools and libraries.  I am about through with 
all that and may actually get back to slinging new code soon.  (Well I 
want to put up a web page first, and put a lot of my other stuff on it 
now that I have it updated...)

I don't know if you can use this, but you can have a look at serpent:

There's an Ada implementation of the Solitaire algorithm at

It's quite old but I've been using its SHA1 and Tiger implementation 
without any problem. It has other digital signatures as well:

Yes, I found ACF as well. It does have hash functions, but digital 
signatures also require public key cryptography (or its moral 
equivalent). Unless I'm missing something significant, it doesn't look 
to me like ACF supports such things.

Is ACF dead, BTW? It looks like it has the potential of being a nice 
project. Should it prove necessary for me to implement digital 
signatures myself I might be interested in contributing the result to 
the open source community and ACF seems like one option for that. I 
wrote to the administrator of the project, but so far I have not gotten 
a reply.

Ah, my bad, I had interpreted digital signatures as digital 
fingerprints. No, I don't think that ACF have anything else that hashing 
calculations.

I wrote him some months ago. He took some time to answer (a couple of 
weeks?) but he is out there, somewhere, at least.

For digital signatures, I developed a framework and implementations of :
MD5, SHA-1, HAVAL etc. I also started on a framework for implementing
multiple cipher algorithms but only got rc6 done. I will be happy to share
it. you may email me @ r.srinivasan[nospam]@cox.net
