As shown in the figure below:

Step 3: Click "Browse files..." Button, and select "HTML files and web resources" in the lower right corner of the select file interface.

Step 5: Click the "start" button in the encryption interface to encrypt the above three files.

After encryption, we need to replace the encrypted file (please make sure to backup the source file before replacement!) , replace first index.html and meeting.html. Then replace the index.js.

5. To access the encrypted zoom web client SDK page:

Finally, we use the Xvast browser to access the http://localhost:9999, enter the username and password to obtain the license in the login window. (default username: testuser, password: 123456).

After you log in and obtain the license, you will visit the join Zoom conference page.

Of course, you can also modify the style of the index.html source file. Please re-encrypt and replace the file after modification.

The following picture is the modified join meeting page effect, or you can cancel the join meeting page, you can integrate it with your website, automatically obtain the user's username and join the meeting, please refer to: How to use Zoom Web Client SDK Integrate with your website?

After entering the meeting number and meeting password, click the Join button to join the meeting.
The effects of the meeting are as follows:

It is recommended that the conference presenter use the Zoom desktop client to start the conference.

After you test that everything is working properly, please upload the Zoom Web Client SDK code to your server for deployment. You can also make Zoom Meeting on your website through deep modification.

Encryption security instructions: DRM-X 4.0 only encrypts the Zoom Web SDK web pages, so users must use Xvast to access Zoom meetings, so it supports DRM-X 4.0 Prevent Screen Recording, Watermark and other functions. However, DRM-X 4.0 does not encrypt the video data transmitted by the video conference, and the security of the video conference is the responsibility of Zoom.
