how to create a digital signature in excel

Digital signature apps are also available for iOS and Android.

By the way, some web apps, including CoSign, can sign and verify Word and Excel documents, in addition to the usual PDF files.

For browser access, you need a web app that supports signing and verification.

My company, CoSign, has mature SharePoint Server and SharePoint Online digital signing products. The software is often integrated into an ECM system such as SharePoint.

On a server, you can sign and verify PDF, Word, and Excel documents by using software/hardware from different vendors.Note that signing requires a signing infrastructure that supports the local APIs that the apps use: CAPI / CAPI NG On a PC, Microsoft Word and Excel have native features for digitally signing Word/Excel documents and for verifying signatures on signed documents.So can Nitro Pro, Bluebeam Revu, Foxit Phantom, and other PDF software. On a PC, Adobe Reader (or Acrobat) can verify the digital signatures on a PDF file.This can be done at people's workstations, on a server, via a browser, mobile app, etc.

This standard is harmonized with the Digital Signatures section of the PDF specification, the NIST digital signatures standard, etc.Īssuming the above, the answer about verifying the signed documents is that there are many software apps that can verify standard digital signatures. I think that the question is about standard digital signatures, eg for PDFs the most real-world, harmonized document is PAdES.

Standard digital signatures or 'digital signature'? In response to the original question and the comments from sk1 to another answer:
