Last Nowina Nexu Not Detected on the DSS-Demonstrations Web Site

[IPConvergence]

Hello,

on our project, we are trying to use the dss-demonstrations to sign a digest with CAdES, JAdES signature.

dss-demonstrations site installation is running find and web site is running also.

Problem happens when we go on the page "sign a digest" section, at the bottom we have the following message: "NexU not detected or not started !".

We have installed the Nowina Nexu software coming from the page "https://nowina.lu/solutions/java-less-browser-signing-nexu/"

When it is installed, I use the Nowina Demo "https://lab.nowina.solutions/nexu-demo/" and it works perfectly to sign a pdf with my Belgium eID card and an USB Reader. It works perfectly on a MAC (with Chrome) and on a Windows PC.

Problems happens when I use the dss-demonstrations app:

• With Mac PC and Chrome browser, my USB reader is not detected, so it seems that your app is not integrating well with the Nexu driver app. "NexU not detected or not started !". But with Nowina demo app, it works perfectly.
• With Windows PC, USB Reader is detected, but when I select signing with Cades of a digest, signing process start and then in the middle of the process it stop with error .

So we are unable to sign any digest with your des-demonstrations App. (same behaviour if we use the https://ec.europa.eu/cefdigital/DSS/webapp-demo/sign-a-digest)

How can we solve that issue?

Hello,

The DSS demonstration hosted by CEF relies on the community open-source version of NexU: https://github.com/nowina-solutions/nexu

The ready-to use bundle can be downloaded directly here: https://github.com/nowina-solutions/nexu/releases/download/nexu-1.22/nexu-bundle-1.22.zip

The Pro version of NexU provided on the Nowina website is a test version intended to be used exclusively on the Nowina Lab to try the software.

Hope this helps,

Kind regards,

Jean-Emmanuel
