Need your help: I have a web application (back - .NetCore; front - Angular).

How to sign an Excel file generated on the server using an EDS on a client? It's required that, as a result, the user can receive the signed document and the digital signature is visible inside when he open the .xls file. In addition, using a separate button, I need to be able to save the document in PDF with a visible signature that contained the full name, date and time Documents NOT signed with EDS in .xls and .pdf formats are created on the server. But how to embed a digital signature in them on the client?

Since your question has tags angular and asp.net-core, I assume that you are talking about web application and by client, you mean web browser. If that is the case, you require Browser Extension on browser. If you are talking about thick client application, you require equivalent agent on client.

For modern browsers as client, please refer to Accessing ePass2003 Auto token through browser. This applies equally to EDS on USB token or Smartcard or in Windows Local Certificate Store.
