Hey!
E-sign creates an authentication for the file. Once the PDF is signed, if anyone tries to edit the file, they will lose their signature. For Data Reports, which seems to be their main focus, it is probably an over engineering, but it can be applied to any other type of document that we want to make sure it's legit.

Thank you for elaborating on your use case with E-sign!

I'll pass this information for internal reviewing and see whether it is a possible fit for implementation or not (and how we can best support it).

We appreciate your interest in Hybiscus!
