Digital Signature not valid

Divinus · March 4, 2020, 12:40pm

Hello,

I have a problem with digitally signing an Excel file using Cells for Java 18.4.
Regardless of what I export, Excel complains about a changed content after opening file.

With this message I send a ZIP file with a test case and the corresponding Test Certificate including CA and screenshots of Excel.

aspose-cells-signature-test.zip (1.2 MB)

Thanks for your help.

@Divinus,
Thank you for your query.

I have tried the scenario using latest version Aspose.Cells for Java 20.2 but could not observe any issue as the output file opens fine in MS Excel. Could you please try it with the latest version and share the feedback?
