RFC 3161 Protocol compliant external Timestamp on PDF Document

Hello everyone,

Is there a plug-in, or an option in Appian, to implement a RFC 3161 Protocol compliant external Time Stamp, when applying a Digital Signature to a PDF document?

The Timestamp should be embedded in the PDF document itself.

There should be a possibility to choose the Hash algorithm which can be one of the following:

  • SHA1
  • SHA256
  • SHA512
  • MD5

Any help is appreciated.
