Hi Marten and Bas,

Thanks for these replies, and good to know I can expect it to be fairly 

I think I might try using the jsonwebtoken npm library - 
https://www.npmjs.com/package/jsonwebtoken.  I know I could put it 
together with the lower-level Omnis workers, but this seems like the 
ideal time to bite the bullet and get into node.js with Omnis.

It's the 3rd part which encodes the hash which allows you to verify the data came from a known source as only the source and destination have the secret key.
