A TV series from nowe.com

[CrymanChen]

Hi, folks. I saw a TV series from nowe.com. It is a website from Hong Kong SAR, China where you can enjoy plenty of dramas.
Unfortunately the series in this post needs premium account, and it may be inappropriate to ask my friend to put his account and passwords online...
So maybe I'll show some screenshots to you.

It is mpd-dash and I searched ".mpd", found a mpd file in the following picture:

and the content of the mpd file is as below:

I gained some experience that dealing with mpd-dash videos, I need some information to decrypt.
so I checked the mpd file, found the highest resolution is 1080p (good resolution).
and in the "ContentProtection" area
I found the code below:

<ContentProtection schemeIdUri="urn:uuid:9a04f079-9840-4286-ab92-e65be0885f95"><mspr:pro xmlns:mspr="urn:microsoft:playready">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</mspr:pro></ContentProtection>

I've learned that the crucial part is here, so I tried to decrypt these meaningless characters in base64.

here is what I got:


[Attachment 64515 - Click to enlarge]

the result is

`   V <WRMHEADER xmlns="http://schemas.microsoft.com/DRM/2007/03/PlayReadyHeader" version="4.0.0.0"><DATA><PROTECTINFO><KEYLEN>16</KEYLEN><ALGID>AESCTR</ALGID></PROTECTINFO><KID>4f+vhItifjG16xfWNfOu1A==</KID><CHECKSUM>GW1/SebhrDI=</CHECKSUM><LA_URL>https://profficialsite.keydelivery.mediaservices.windows.net/PlayReady/</LA_URL><CUSTOMATTRIBUTES><IIS_DRM_VERSION>8.0.1611.1001</IIS_DRM_VERSION></CUSTOMATTRIBUTES></DATA></WRMHEADER>

and here I'm confused.

It seemed that there isn't pssh value, nor there is the internet url of the license.

'Cause maybe when you've got both the pssh value and the license file, you can get the key to decrypt, right?

now what should I do? I'm stuck here, just like I don't know how to solve a difficult math quiz.

I'd appreciate it if any mogul could teach me about this point, because learning how to get the source video is so interesting. (No malice, just wondering how it works)

Thaaaaaanks~

oh, another point.
if there is something in my post that is forbidden, please just tell me.
I sincerely and humbly accept all accusations and criticisms.

[LZAA]

Url?

[jack_666]

of all the info you posted, this is the most important piece

<KID>4f+vhItifjG16xfWNfOu1A==</KID>

use that to get your pssh, which is

AAAANHBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAABQIARIQhK//4WKLMX616xfWNfOu1A==

Now you need the license URL and the curl of the lic url call

[[ss]vegeta]

I sincerely and humbly accept all accusations

You are the reason for Depp's and Heard's divorce.

[CrymanChen]

Url?

Sure.
the URL of the video is: https://www.nowe.com/watch/202101181269896/%E6%A8%A1%E7%AF%84%E5%88%91%E8%AD%A6-%E7%AC%AC4%E9%9B%86

Thanks. And it seems to be hard to find the exact place of the license, in that there're so many files in the dev tool

Thanks. And it seems to be hard to find the exact place of the license, in that there're so many files in the dev tool

thats why you need to filter the requests on the network tab - "method:POST" is a good start, it should reduce the number of requests drastically (or filter for "license", "wv", "cenc", "widevine", etc)

id also try this pssh if the other one doesnt work

AAAAMnBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAABISEOH/r4SLYn4xtesX1jXzrtQ=

Nowe uses json format in the license request too, so you'll need a py script to get keys, not just getwvkeys.cc

If that didnt happen we couldnt enjoy all the clips of Depp in the court case

OMG... So it is never an easy thing to decrypt... Anyway, thank you~

Sorry to trouble you, Jack. I have another question.

I'm wondering how you convert the kid value to pssh value.

Is this base64-encoded or something else? It would be very kind of you if you could tell me how to do it.

kid to pssh can be done with axinom tools pssh box generator....put your kid and necessary details here

Thank you so much.
