Virtual CSP

Sign documents using your remote keys

Sign documents using your remote keys

Virtual CSP is a custom provider for Microsoft Windows Cryptographic Service Providers (CSPs), which allows you to sign documents using your remote keys. It removes the need for local hardware such as smart cards and USB Tokens, but without changing the user experience. The signing keys and certificates are managed centrally at the server side (ADSS Server).

FEATURES & BENEFITS

Sign documents within your business applications

Users can sign any document/file directly within their business 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.

Manage your remote certificates

Virtual CSP is in fact a Windows plugin for Microsoft Cryptographic Service Provider to manage your remote certificates. This plugin hooks into the Windows CSP module and pushes your server held digital certificates into your Windows Keystore for signing documents and other data from different desktop applications.

Signing keys protection

The access to the signing keys is protected by remote authorisation that is done via Ascertia Go>Sign Mobile app available for iOS and Android. Signing can be performed using any CAPI or CNG aware application. These can be off-the-shelf Microsoft Office applications or any 3rd party application like Adobe Acrobat Professional or custom desktop apps.

Authentication options

Virtual CSP supports four authentication options to perform signing:

No Authentication
Password Authentication
Remote Authorisation using Ascertia Go>Sign Mobile app
Password and Remote Authorisation using Ascertia Go>Sign Mobile app
