Hi,


Is there currently a way to verify if an excel document’s macros are digitally signed?

Thanks,

Hi,


Please see the document:
http://www.aspose.com/docs/display/cellsnet/Assign+and+Validate+Digital+Signatures

I am afraid, we only support to assign or validate digital signatures for Excel workbook or files. We do not support to verify if an Excel file’s macro/vba codes is digitally signed. In fact Aspose.Cells does not support to access, create, manipulate or even execute macros in the workbook, it only supports to retain the macros/vba codes (if your template file has it already) and save as the file with it.

Thank you.

@pilotdave413,

We are pleased to announce that latest Aspose.Cells for .NET version (you may get the latest version here) supports to digitally sign vba code project/macros with certificate, it also supports to check if digital signature for vba code is valid. Please use the following APIs:

VbaProject.Sign(DigitalSignature digitalSignature)
VbaProject.IsValidSigned

See the documents with example code for your complete reference.
Digitally Sign a VBA Code Project with Certificate
Check if Digital Signature of VBA Code is Valid

Moreover, Aspose.Cells now supports to access, create and manipulate macros/vba code in the workbook although it does not support executing macros yet.

We also recommend you download our featured demos to test variety of different features.
