Get E-Mail-Address from DigitalSignature-Information

Hello,

i have several SignatureFields in my PDF (every field marked as required).

If everybody who needs to sign this document has signed ... i want to do this:

• A Button should appear in the PDF ... named "Notify" ... should not be that problem
• By hitting this "notify"-Button a script should write an email to a specific email (which is not static ... and can change ... depends on the initiator of the PDF)
  • the email-address should come from the digital signature in a specific SignatureField (for example "SignaturInitiatorField")

Is this possible via JavaScript?

• The extraction of an email-address from the SignaturField/DigitalSignatur
  • This information is integrated in the certificate
    • Subject Name
      • email=XXX@YYY.com

And if it is possible ... how can i do this?

Regards
