Description

After signing a PDF file, Adobe Reader show an icon on top of the document with the following text: "Signed and all signatures are valid".
I would like to certify the file and obtain the following icon text message :
"Certified by xxx certificate issued by xxx".

In my opinion this improvement will come with an explicit support for certification signatures :
NOT_CERTIFIED (Approval signature)
CERTIFIED_NO_CHANGES_ALLOWED (Author signature, no changes allowed)
CERTIFIED_FORM_FILLING (Author signature, form filling allowed)
CERTIFIED_FORM_FILLING_AND_ANNOTATIONS (Author signature, form filling and annotations allowed)
