How do I decrypt a .ts file for which I have the encryption key ?

[ng.newbie]

I have downloaded a video, but I need to decrypt it.

The video is .ts file and the key is binary content within a file.

Is there any way I can decrypt this ?

I tried ffmpeg but the key needs to be an ASCII string that you supply via command line.

Any other tool I can use ? Or some other way via ffmpeg ?

I am attaching the key just in case. Please note its a binary file which I had to mark as txt to upload.

I am getting the following error with N_m3u8DL-RE:

I am only able to download till 25-26 % before it errors out.

Is there any way I can download the all the ts files and then decrypt ?

There seems to be a tracking URL being called periodically on the browser hence it might stopping the download of the video after a point.

But the good news is whatever I am able to download is successfully decrypted. Hence the decryption key and process is valid.

My mistake, I was running BurpSuite in the background to intercept the requests. It was corrupting them somehow.

Once I disabled BurpSuite everything worked like a charm, N-m3u8DL-RE didn't even need the key param. It downloaded everything seamlessly.

Thanks again.

I may be wrong but I don't think that's your real key. Can you provide link to the original video?

[lomero]

this isn't key
aes key is 32 character, alphanumeric, without - symbol. also real key is in hex value

Hi, I do not have the link, I have a video player that I am assuming decrypts these videos and I can play these videos only in the video player, How can I find the encryptian key?

Name of the video player software? Can any video player play it? VLC wasn't working.

Edit: if you didn't get these videos from a link, then where did you get them from? Or is the source link no longer available.
