How It Works
  1. Click the signature button in the toolbar to initiate the signing process
  2. The app requests an authentication token from the DWS API with signing permissions
  3. The Web SDK generates a document hash and sends it to the DWS API for signing
  4. The DWS API signs the document hash using its secure signing service
  5. The signature is returned and applied to the document in the viewer, maintaining end-to-end document privacy

This sample demonstrates digital signature integration with Nutrient DWS API. Requires NUTRIENT_API_KEY environment variable to be configured

Note: Signature validation requires CA certificate configuration. For production use with full validation, contact Nutrient support for certificate setup.
