We just finished writing a document on LabVIEW Cryptography. It's a detailed paper on how encryption works, and how to use LabVIEW tools to do secure communications through cryptography. This represents the state of things today. We'll update this next year when we add encryption to more of the native LabVIEW communication tools.
In the paper we reference a great tool from LVS - the Encryption Compendium for LabVIEW. If you are trying to lock down your data, this tool is worth checking out. I appreciate their help in reviewing the cryptography paper for accuracy before we finalized it.
I'm working with our web team to publish this on our main site, but I wanted to give this group an early preview. Let me know if you have feedback!
