PKI tokens provide secure storage for digital certificates and private keys. They allow public-key cryptography and digital signatures to be leveraged securely, without risk of leaking the private key information. Although there is tremendous interest in the use of remote (central) signing, there are still a large number of users needing to sign using keys and certificates held locally on smart cards, USB tokens, Virtual CSP keys/certificates held centrally and of course local software key stores. To enable web applications to be able to sign using these keys and certificates, Ascertia has a middleware product called ADSS Go>Sign Desktop. ADSS Server Go>Sign Service communicates with Go>Sign Desktop using JavaScript and supports any modern HTML5 browser. By default, ADSS Go>Sign Desktop application accepts connections from any application.


ADSS Go>Sign Service empowers business applications to perform document signing on user’s machines using the credentials held either locally by the user or on the server.


In the ADSS Web RA, Go>Sign Service is used for certificate generation and the users can issue certificates and securely store the user’s private key on smart cards and USB tokens.
