Description

Signing with:

• pdfbox-app-3.0.0-20210804.050614-2786.jar causes the invalid signature.
• pdfbox-app-2.0.24.jar causes a valid signature.

By full scanned document I mean that the document is full of images.

The attachment "unsigned.pdf" is the first file that I couldn't sign.

The attachment "file.pdf" is the second file that I couldn't sign also. 

The attachment "file_signed.pdf" is the result of signing "file.pdf". With Adobe Reader you can check that the signature is invalid.

Maybe it is related to having tables and images in the document.
