Izindaba zisanda kukhishwa ukuthi I-Google icele iGitHub ukuthi ivimbe amakhosombe angu-135 endaweni yesikhulumi, eyi ihlobene ngokufaka ikhodi ukuchaza okhiye bokususa ukubhala okuqukethwe okuvikelwe kwe-Widevine I-CDM (Imodyuli Yokubhala Ngokuqukethwe) ivinjiwe ngaphansi kwe-US Digital Millennium Copyright Act (DMCA).
Leli qiniso limangaza abaningi njengoba iGoogle ibikade iyisu lokungabi nolaka. ezindabeni zobunikazi bokusungula, kepha ngo-2018, isiqubulo esithi "Ungabi mubi" sasuswa eMithethweni Yokuziphatha.
Ingidi yaqalwa ngokumelene nezinqolobane eziqukethe ukhiye wangasese we-RSA ekhishwe kwi-CDM kaWidevine ngenxa yegebe ezindleleni zokuvikela ezisetshenziswe kule module.
Inqolobane eminingi imfoloko ye-plugin ye-Chrome i-widevine-l3-decryptor, ekuvumela ukuthi ufinyelele kokuqukethwe okusakazwa ngesiteshi sokuxhumana esivikelwe i-DRM.
Le plugin yabhalelwa ukukhombisa ukuthi indlela yokuvikela i-DRM yeWidevine ingadlulwa kanjani ngokuvimba izingcingo ze-API ezibetheliwe zeMedia (EME) API nokubuyisa konke okhiye bokubethela okuqukethwe abadlulisiwe.
Indawo yokugcina ithi ikhodi iyindlela yokubonisa indlela yokuhlasela futhi isatshalaliswa ngezinjongo zokufundisa kuphela (i-plugin ayikubhalisi ukubhala okuqukethwe, inquma kuphela ukhiye, kepha ukhiye otholiwe ungasetshenziselwa ukubhala ngemfihlo kusetshenziswa i-ffmpeg utility, kucacisa ukhiye otholwe ekuqaleni ku-"-decryption_key").
I-Google idala futhi isabalalise i-Widevine's Content Decryption Module (CDM), enelayisense yokusetshenziswa kuziphequluli eziningi, kufaka phakathi i-Google Chrome, iMicrosoft Edge, iMozilla Firefox, ne-Opera. I-CDM kaWidevine isetshenziswa ngokubambisana neseva yelayisense yakwaWidevine ukusabalalisa ividiyo ye-DRM nokuqukethwe komsindo kwi-Intanethi futhi isetshenziswa abahlinzeki bokuqukethwe okubandakanya iDisney +, iNetflix, i-Amazon Prime Video, i-YouTube, iHulu nabanye, ukuvimbela ubugebengu. wokuqukethwe evikelwe yi-copyright.
I-Google LLC ingumnikazi welungelo lobunikazi ku-Widevine CDM futhi ilinikeza amalayisense kwabanye ukuthi bayisebenzise ngaphandle kokuguqulwa noma ukwabiwa kabusha ngaphansi kwemigomo ye-Widevine Master License Agreement.
Ukwephulwa kweSigaba 1201 se-Digital Millennium Copyright Act (DMCA) kucashunwe njengezizathu zokukhiya, futhi i-plugin uqobo ihlatshwe umkhosi njengethuluzi elenzelwe ukwephula imigomo yokusetshenziswa kokuqukethwe okunelayisense futhi kudlula izindlela zokuvikela ze-DRM.
Phakathi kokwephulwa komthetho, ukuba khona kwamafayela nakho kukhulunyiwe endaweni yokugcina izinto ephula ilungelo lobunikazi le-Google.
Ikakhulu, ifayela le-licence_protcol.proto kanye ne-Widevine Modular DRM Security Integration Guide kanye nemibhalo yokubuka konke ye-Widevine DRM Architecture. Ngokuphawulekile, ilayisense_protcol.proto yifayela eliyisihloko le-libprotobuf elinencazelo yesakhiwo se-Widevine protocol, okusho ukuthi, i-Google iphikisana eduze nokucabanga kwe-Oracle kuhlasela i-Android.
Okwalabo abangazi ngobuchwepheshe Umvini omkhulu, kufanele bazi ukuthi lokhu ithuthukiswa yiGoogle futhi isetshenziswa kakhulu ku-Chrome nakuzinhlelo ezahlukahlukene (imvamisa i-Linux) ukwazi ukubonisa okuqukethwe okuvikelwe yi-copyright ku-Netflix, Disney, Amazon Video, BBC, HBO, Facebook, Hulu, Spotify nezinye izinsiza eziningi.
Kunikezwa imodyuli ye-CDM wegama elifanayo ukucacisa okuqukethwe, okusetshenziswa ku-Chrome, Edge, Firefox naku-Opera, kanye nasemikhiqizweni evela kwa-Samsung, Intel, Sony kanye ne-LG.
Ngonyaka odlule, izinga lokuphepha elibuthakathaka, iWidevine L3, laqhekeka, lasetshenziswa ngokuphelele kwisoftware, futhi lisetshenziselwa ukusabalalisa okuqukethwe ngaphansi kwe-1080p.
Kuvele ukuthi ukuqaliswa kwe-algorithm yokubethela i-Whitebox AES-128 kungenzeka ukuthi kuhlaselwe i-Differential Failure Analysis (DFA), okuvumela ukufinyelela kukhiye wokubethela.
Okokugcina, uma unentshisekelo yokwazi okwengeziwe ngayo mayelana nesicelo esenziwe i-Google ku-GitHub, ungabheka imininingwane Kulesi sixhumanisi esilandelayo.
