Verifying digital signatures in portfolio

[harish5E5A]

Hi,
I am having pdf collection which has multiple pdf files in it. Each pdf has digital signature. So I am wondering is there any way to verify all signatures when opening the collection.
Thanks in advance.

Hi Harish

Hope you are doing well and sorry for the trouble. As described you want to automatically verify the digital signatures in the PDF portfolio.

To automatically validate all signatures in a PDF when you open the document, select Verify Signatures When The Document Is Opened. This option is selected by default.

Go to Edit (Win), Adobe Acrobat (Mac) > Preferences > Signatures > Click 'More' under Verification and then elect Verify Signatures When The Document Is Opened.

For more information about validating signatures please check the help page https://helpx.adobe.com/acrobat/using/validating-digital-signatures.html
