Hi,
I'm trying to find a hex key for mp4 decrypt. The below link uses sample-aes
The link for the video is: https://www.virginmediatelevision.ie/player/show/1784/0/0/Darklands
I've gotten the m3u8 link and downloaded the encrypted ts files and can merge them. I'm going through the responses in the link but can't find the kid.
I was able to get some of the base64 cert but I don't think I needed that. I've tried using the authorization_data and converting to hex but it's not giving me a 128 bit key in hex.
I think I'm close but can't get the final bit.
Is the below relevant ?
Code:{"authorization_data":{"pmajluaTE6kttAQ_vnVjd2zIPZP3w9-T":{"authorized":true,"code":"0","message":"authorized","request_timestamp":"1571904832","retry":1576800000,"synd_rule_failures":null,"require_mid_stream_check":false,"require_heartbeat":false,"restrict_devices":false,"is_cmaf":false,"streams":[{"delivery_type":"hls","url":{"format":"encoded","data":"aHR0cHM6Ly9wbGF5ZXIub295YWxhLmNvbS9obHMvcHJveHkvcG1hamx1YVRFNmt0dEFRX3ZuVmpkMnpJUFpQM3c5LVQvXy5tM3U4P3NvdXJjZT1odHRwcyUzQSUyRiUyRnNlY3VyZS1jZi1jLm9veWFsYS5jb20lMkZwbWFqbHVhVEU2a3R0QVFfdm5WamQyeklQWlAzdzktVCUyRjElMkZmcF90cyUyRm1hc3Rlci5tM3U4"},"drm":{"fairplay":{"la_url":"https://player.ooyala.com/sas/fps/9xYzYyOknvGbEMCwNxWolOAUrbjB/key","certificate_url":"https://player.ooyala.com/sas/fps/9xYzYyOknvGbEMCwNxWolOAUrbjB/certificate?auth_token=cjRFZjc2YStweEJqMTJDVlpheDJtQjZiSmNUM2VkVmxQQlVRWVloY1NBVE54VncrWHFsU1BaMlY0bGIwCkpsdnEvZ2hSYnRsYlF0Ym02ampPc2ZhYVBtZ2YvT211T09xT2Vwd0szem9vdXVDYWpEdkU1QXByS0lIUwpDM2lWcDlBWTlKSkR1M2k5elJCSlUwOG9hSXVuVlBVY2N2czJZamhoYXc2ME1ndkU4b24wQjhad3NZdFcKL2QzVXV6cXJsYnVHQmpBenA3NFB6Q0EySHhibDQ0UjRUa0VSNWJUYWZCRGlud01va05oSWpSVFdIejNmCllOQkgyQndiRWd2VFcxcUgK"}}},{"delivery_type":"dash","url":{"format":"encoded","data":"aHR0cHM6Ly9zZWN1cmUtY2YtYy5vb3lhbGEuY29tL3BtYWpsdWFURTZrdHRBUV92blZqZDJ6SVBaUDN3OS1ULzEvZGFzaC8xLm1wZA=="},"drm":{"playready":{},"widevine":{"la_url":"https://player.ooyala.com/sas/drm2/9xYzYyOknvGbEMCwNxWolOAUrbjB/pmajluaTE6kttAQ_vnVjd2zIPZP3w9-T/widevine_modular/ooyala?auth_token=cjRFZjc2YStweEJqMTJDVlpheDJtQjZiSmNUM2VkVmxQQlVRWVloY1NBVE54VncrWHFsU1BaMlY0bGIwCkpsdnEvZ2hSYnRsYlF0Ym02ampPc2ZhYVBtZ2YvT211T09xT2Vwd0szem9vdXVDYWpEdkU1QXByS0lIUwpDM2lWcDlBWTlKSkR1M2k5elJCSlUwOG9hSXVuVlBVY2N2czJZamhoYXc2ME1ndkU4b24wQjhad3NZdFcKL2QzVXV6cXJsYnVHQmpBenA3NFB6Q0EySHhibDQ0UjRUa0VSNWJUYWZCRGlud01va05oSWpSVFdIejNmCllOQkgyQndiRWd2VFcxcUgK"}}},{"delivery_type":"smooth","url":{"format":"encoded","data":"aHR0cDovL3NoLWMub295YWxhLmNvbS9wbWFqbHVhVEU2a3R0QVFfdm5WamQyeklQWlAzdzktVC8xLmlzbS9NYW5pZmVzdA=="}}]}},"user_info":{"ip_address":"","domain":"","request_timestamp":"","device":"","language":"en-US","country":"","timezone":"","continent":"","region":"","state":"","city":"","latitude":"","longitude":""},"debug_data":{"server_latency":"18.206305999999998","request_id":"5224ef115f9c974e2a7ae76072a2e500","user_info":{"request_timestamp":""},"provider_enabled_ssl":true,"provider_not_use_cookies":false},"auth_token":"cjRFZjc2YStweEJqMTJDVlpheDJtQjZiSmNUM2VkVmxQQlVRWVloY1NBVE54VncrWHFsU1BaMlY0bGIwCkpsdnEvZ2hSYnRsYlF0Ym02ampPc2ZhYVBtZ2YvT211T09xT2Vwd0szem9vdXVDYWpEdkU1QXByS0lIUwpDM2lWcDlBWTlKSkR1M2k5elJCSlUwOG9hSXVuVlBVY2N2czJZamhoYXc2ME1ndkU4b24wQjhad3NZdFcKL2QzVXV6cXJsYnVHQmpBenA3NFB6Q0EySHhibDQ0UjRUa0VSNWJUYWZCRGlud01va05oSWpSVFdIejNmCllOQkgyQndiRWd2VFcxcUgK","auth_token_expires":1571991232,"signature":"bv6L0NXRMaRiNV53X5j26IjRYIASJ/UbjxgONxY8sOY="}

So I've gone through the mpd file.
Streamlinked the mpd to get the encrypted Mp4 file.
I've then gotten the pssh box decoded and the below header gives a kid but when base64 decoded and expressed as hex won't decrypt the file.
Code:<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>diefjtGbRVKc3JCT8OMM+Q==</KID> <LA_URL>https://player.ooyala.com/sas/drm2/9xYzYyOknvGbEMCwNxWolOAUrbjB/hlZzJvaTE6J2_InG5VWOxk7yQHf_tvSm/playready_cenc/ooyala/version/1</LA_URL> </DATA> </WRMHEADER>
