How to get encrypted m3u8 key from this website?

[hoangdu]

Hi all,
Perhaps this is one of the most difficult site to get the key of m3u8 stream at this moment. Can you please try to decrypt the key from it? You can connect to this Vietnamese website with free vpngate or your prefer vpn service that you have. You don't need subscription to watch some free contents. Here is one of them:

When I track the license from the stream and I got not 16 bytes key but an encrypted key. As you can see this is the response of the key from server for this channel: Here is license server request

https://license.sigmadrm.com/license/verify/sigma?keyId=71d15eef-03bb-4282-8178-5257f8c2d73d&assetId=vtv4_v2_SD&uuid=cf20e92d-5869-4d47-ac9f-1248ab44f6e5

and here is the response of the key

Still same keyId but each time response of the license from server is different.

Yes, of course. This is how public key encryption works.

Yes, of course. This is how public key encryption works.

That's the reason I want to ask if someone are able to decrypt it? Seem that this js

https://cdnwebonplay.gviet.vn/public/drm/v2/sigma_drm_2.0.4.js

is responsible for decryption process. But I am not good at js.
