This example uses PDF Document API to validate signatures and generate validation reports.

PDF Document API – Validate Document Signatures

The following sample project uses the DevExpress PDF Document API to generate signature validation reports.

To test, simply click Browse to load the desired PDF file. If the file contains signatures, the table will display signature information as pictured below.

Implementation Details

The GetSignatureInfo method retrieves all signatures contained in the PDF file. Each signature from this list is then passed as the GenerateInfoList method parameter. This method retrieves signature name, signer’s name, and certificate information to generate the information list. The VerifySignature method verifies signature validity. The generated list is displayed in a DxGrid table.
