Certification termination error: "SigValue is 536 bytes larger than expected."

[Pyramide2003]

Certification of the PDF with Acrobat Reader is not possible. An error message is displayed at the end of the signature process. "SigValue is 536 bytes larger than expected."

See the screenshot.

I couldn't find the cause. It used to work. The reader's repair procedure was also unsuccessful.

The Secommerce SecSigner 7.15 with a licensed Acrobat Reader DC plug-in is used. Clean installed. Win 10 Professional

Can someone from the community kindly give me some advice? Thank you.

Hi there

Hope you are doing well and and sorry for the trouble.

- Is this a behavior with a particular PDF file or with all the PDFs? Please try with a different PDF file and check.

- What is the version of the Adobe Acrobat Reader DC you are using? To check the version go to Help > About Acrobat and make sure you have the latest version 21.05.20058 installed and reboot the computer once. Go to Help > Check for Updates.

As repairing the installation doesn't work, please try to reset the Acrobat preferences as described in the help page https://community.adobe.com/t5/acrobat/how-to-reset-acrobat-preference-settings-to-default/td-p/4792...

If it still doesn't work please create a new test user profile with full admin rights in Windows or enable the root account in Mac and try using the application there and check.

Regards

Amal
