I would like to offer my SHA-1, SHA-2 HMAC and AES files to OpenG to add to the MD5 library (I suppose we need to rename that palette).

You can find these functions currently in the LAVA Code Repository.
The code is currently in 2010, but I can backsave to 2009.

Hey Ton, having these functions in OpenG sounds like a great idea.

Sweet!

Kudos!

Does anybody have a good name for such a functionset?

OpenG Cryptography Library

Vargas has Crypto-G, other names I can think of are Encryption or Security.
But I think Cryptography is best.

[mje]

Cryptography is nice, but also implies some levels if security that are used when handling data passed to the methods which most definitely can't be satisfied in G code. I'd say encryption or even simply hashing is a more honest description.

Maybe some more could be added aswell. I say
- AES, http://www.soslabvie...library-labview
- HillCipher, available also somewhere on the web
- CeasarCipher (easy)
- Blowfish

-edit- oh and the output of the md5 and SHA VI's have to be the same in my opinion. I believe the VI's of Ton have 3 different output formats.

Christian Loew implemented it for Reference Design for Adding Licensing to LabVIEW Real-Time Applications (I have used the code for a licensing requirement - its really good) and he also has it available here.

Question what exactly needs to be done before the code gets reviewed for OpenG? I guess that the diagrams need some cleaning up. But anything else?

I have already discussed this offline with Ton.
After some minor changes that Ton wants to make the package will be submitted for review by OpenG.
So the ball is already rolling...

[Ton Plomp]

One of the things that needs to be done is have good unit -test VIs.

The current set I have is created by the NIST and is very thourough. Currently all the functions pass these, however I need make that a single-test routine (running about 5-10 minutes).

As I already posted somewhere here (on AES implementation in native LabView), I created AES encrypt/decrypt VIs and they are ready to be downloaded at http://vigods.com/to...curity/aes.html (and to be used absolutely for free ).
