Virtual CSP

Remote Signing From Windows Desktop applications

Remote Signing From Windows Desktop applications

Ascertia’s Virtual CSP (Cryptographic Service Provider) is a lightweight plug-in for the Microsoft Windows operating systems which allows documents, emails and other data formats to be signed remotely (i.e. server-based signatures).

Virtual CSP removes the need for deploying smart cards or USB Tokens to end-users. The user’s signing keys and certificates are instead managed centrally within the ADSS Server. The user can remotely sign documents from any Microsoft Windows based application without changing that application’s native user experience.

Virtual CSP therefore helps reduce costs and ensures a more user-friendly approach to signing documents from Windows applications.

FEATURES & BENEFITS

Sign documents within your business applications

Users can sign any document or file directly within their Windows-based desktop applications without the need to upload to a hosted service. In addition, the application file format is retained after the signing process. This means no automatic conversion to PDF or other formats. Virtual CSP works with Microsoft Office applications such as Word, Excel, Outlook and also third-party applications such as Adobe Acrobat Professional or custom desktop apps.

Manage your remote certificates

Virtual CSP is a plugin for the Microsoft Windows operating system. It hooks into the Windows CNG layer and is responsible for requesting remote signatures on behalf of the user.

Signing keys protection

The access to the user’s remote signing key is protected through our Signature Activation Protocol (SAP) which ensures strong user authentication and authorisation. This is two factor based approach using the Ascertia Go>Sign Mobile app which is available for iOS and Android.

Virtual CSP supports following authentication options to perform signing:

No authentication (immediate signing)
Password authentication
2-factor authentication and authorisation using the Ascertia Go>Sign Mobile app
