Embedding timestamp token provided by trusted Time Stamping Authority (TSA) to PDF
I have a requirement from client where I need to embed a timestamp token provided by trusted Time Stamping Authority (TSA). The use case is as follows.
1. User logs in to Pega and click on a button
2. Pega generates PDF using the data within Pega
3. PDF needs to be timestamped by trusted TSA
4. User downloads the PDF from Pega
Any suggested TSA which has been integrated with Pega before? If there is, is there any OOTB rule which can accommodate this requirement?
Any suggestions and comments are appreciated!
