I have a few questions using Adobe Default Security when verifying a signature.
I've created my own signing plugin which works well. When I verify my signature it states that it is a valid signature, that the document has not been altered and that the certificate is valid. When I remove my plugin and verify the signature with the Adobe Default Security it states that the signature is invalid and that the document has been altered or corrupted. When I use the DocSign sample plugin to verify my signature it states the the signature is unknown and that the integrety has not yet been verified.
My question are:
As this can't be debugged without a copy of your plugin, files, etc. - you will need to open up a formal support ticket for this with our Developer Support.
