Re: [Secdispatch] [dispatch] Plain text JSON digital signatures

Hi Brian,

Yes, there are are lot of people and organizations that are looking for a solution like this. There are several that I know of that are already looking to adopt this or something similar in production. I also know Anders has been doing a lot of work in the financial sector using this for payment processing. What people need to realize is that plain text signatures and plain text JSON is a fundamental requirement. The proof of concept code I have written so far shows that this works, and works really well. 

It is great to hear that you would support this work, either through a PS or via the ISE. Please let us know if you have any feedback on the ID. 

Thanks
Bret

There was a lot of opposition to the idea previously, so it may be that ISE is all we can get, but I would be willing to work towards PS, either in a new, short lived work group or as part of another work group.

By combining the detached mode of JWS with the JSON Canonicalization Scheme (JCS), JWS/CT enables JSON objects to remain in the JSON format after being signed (aka "Clear Text" signing).  In addition to supporting a consistent data format, this arrangement also simplifies documentation, debugging, and logging.  The ability to embed signed JSON objects in other JSON objects, makes the use of counter-signatures straightforward.

This ID provides a solution using existing IETF RFCs to make this work. Further, this work looks to be adopted by many groups and organizations from financial services, threat intelligence, and incident response.

Ultimately there is a lot of work that could be done in this space to meet the needs of the market. We would be happy with releasing these IDs for ISE publication, or for creating a working group to move them forward. It is just important to note that the market is in desperate need of these solutions. If you want to take it for a spin, there is a JWS/CT playground at: https://mobilepki.org/jws-ct <https://mobilepki.org/jws-ct>
