CTT is implemented as part of C2PA 2.1 by a number of commercial 
implementations from Microsoft, Google and Truepic.  The only open source one 
that I am aware of at this time is from the CAI 
(https://github.com/contentauth/c2pa-rs).

We are also modifying our TimeStamp Manifest (ala ETSI AdES document 
timestamps) to also use the CTT approach.

C2PA may also have code, but we should check that with Leonard (CC'd).
