Xact Web Portal: WebCrypto migration



19 March 2018

the new WebCrypto login module will be available for Clearstream Banking1 Xact Web Portal customers. This new module is offered in parallel to the existing Java Applet based login. The WebCrypto login module offers the same level of security as the Java Applet, and does not require additional software to be installed on the customer’s PC.

Note: Customers also using VestimaPRIME must not migrate to the WebCrypto login, nor must customers using SmartCard authentification.

The following browsers support WebCrypto:

  • Internet Explorer 11
  • Firefox ESR 52
  • Google Chrome

To start using the WebCrypto login, you must migrate your current Xact Web Portal Java Applet user certificates to WebCrypto certificates as described the attached migration guide.

As the new login process is considerably faster and easier to use Clearstream Banking recommends that all customers plan and execute the migration of their Xact Web Portal user certificates at the earliest opportunity.

Further information

Additional information will be available on the WebCrypto support page from 19 March 2018. Please run the “Browser Prerequisite Checklist” to ensure that your web browser fully supports WebCrypto.

For further information, please contact the Connectivity Helpdesk or your Relationship Officer.
