High assurance signatures for your employees

The Entrust Remote Signing Service is a cloud-based turnkey solution that integrates with web and desktop applications that support digital signatures. It enables employees to securely generate identity-verified signatures on documents without the burden of managing digital certificates and signing keys locally.

What is a digital signature?

A digital signature is a special type of electronic signature based on widely recognized PKI technology, which uses digital certificates and signing keys. Digital signing not only authenticates the signature by embedding the identity of the signer, but also helps prevent and flag document tampering.

Entrust can provide globally trusted certificates for digital signing, as well as European eIDAS Qualified Certificates to generate eIDAS Qualified Employee Signatures via the Entrust Remote Signing Service.

Once your account is set up and your employees are onboarded, they can start connecting the Entrust Remote Signing Service to their compatible web or desktop application.

When an employee triggers the signing process from the application, the Remote Signing Service is called to generate a "detached" digital signature from a hash value* that is calculated and sent by the application. This detached signature is then embedded back into the document by the application.

The diagram below illustrates a typical integration of the Remote Signing Service. It does not include the optional timestamping and OCSP flows.

*A hash value is a fixed-length series of digits representing the content of your document. The Entrust Remote Signing Service never receives the content of your documents, which makes it a fast and secure signing process.


The Entrust Remote Signing Service has a native integration with the following applications:

  • Adobe Acrobat Sign
  • Entrust Workflow Signing Service
  • Let’s Sign by SwissSign

You can test the integration of our service with your custom environment, provided it supports the Remote Signing Protocol defined by the Cloud Signature Consortium (CSC).

We are currently working on new integrations. If you'd like to see your signing application listed here, contact us.
