Iindaba zakhutshwa kutshanje ukuba UGoogle ucele iGitHub ukuba ivimbe iindawo zokugcina eziyi-135 eqongeni, ezi enxulumene ngokubandakanya ikhowudi ukuchaza izitshixo ukucacisa umxholo okhuselweyo ngeWidevine I-CDM (iModyuli yoShicilelo lwesiqulatho) ivalwe phantsi kwe-US Digital Millennium Copyright Act (DMCA).
Le nyani iyabothusa abaninzi kuba uGoogle wayeqhele ukuba liqhinga elingenabundlobongela. kwimicimbi yepropathi yengqondo, kodwa kwi-2018, isiqubulo esithi "Musa ukuba bubi" sasuswa kwiKhowudi yokuZiphatha.
Ibhloko yaqalwa ngokuchasene noovimba abanesitshixo sabucala saseRSA ekhutshwe kwi-Widevine CDM ngenxa yesikhewu kwiindlela zokukhusela eziphunyezwe kule modyuli.
Uninzi lweendawo zokugcina ziifolokhwe zeplagi yeChrome i-widevine-l3-decryptor, ekuvumela ukuba ufikelele kumxholo othunyelwe ngejelo lonxibelelwano elikhuselweyo nge-DRM.
Le plugin yabhalelwa ukubonisa indlela yokhuseleko lwe-DRM ye-Widevine enokuthi igqithwe ngokuthintela iminxeba ukuya kwi-API ye-Encrypted Media Extensions (EME) kwaye kufunyanwa kwakhona onke amaqhosha oguqulelo oluntsonkothileyo agqithisiweyo.
Indawo yokugcina iphawula ukuba ikhowudi yimbonakaliso yendlela yokuhlasela kwaye isasazwe ngeenjongo zemfundo kuphela (iplagi ayifihli umxholo, imisela kuphela isitshixo, kodwa isitshixo esifunyenweyo singasetyenziselwa ukuguqulelwa kwentsonkotha kusetyenziswa into eluncedo yeffmpeg, ichaza isitshixo esifunyenweyo ekuqaliseni kwi "-decryption_key").
UGoogle udala kwaye asasaze iWidevine Content Decryption Module (CDM), enelayisensi yokusetyenziswa kwiibrowsers ezininzi, kuquka uGoogle Chrome, Microsoft Edge, Mozilla Firefox, kunye neOpera. I-Widevine CDM isetyenziswe ngokubambisana neSeva yeLayisensi ye-Widevine ukusabalalisa umxholo we-DRM we-audio kunye nevidiyo kwi-Intanethi kwaye isetyenziswe ngababoneleli bomxholo kuquka i-Disney +, i-Netflix, i-Amazon Prime Video, i-YouTube, i-Hulu kunye nabanye, ukuthintela ukukhwabanisa. yomxholo okhuselwe yi-copyright.
I-Google LLC ingumnini welungelo lokushicilela kwi-Widevine CDM kwaye liyigunyazisa kwabanye ukuba bayisebenzise ngaphandle kokuguqulwa okanye ukusasazwa kwakhona phantsi kwemiqathango yeSivumelwano seLayisensi eMastazi eWidevine.
Ukunyhashwa kweCandelo le-1201 loMthetho weMillennium Copyright Act (DMCA) lukhankanywe njengezizathu zokuvalwa, kwaye iplagin ngokwayo ifakwe iflegi njengesixhobo esenziwe ngokukodwa ukophula imiqathango yokusetyenziswa komxholo onelayisensi kwaye unqande iindlela zokukhusela i-DRM.
Phakathi kokuphulwa, ubukho beefayile kwindawo yokugcina izinto oko kwaphula i-copyright kaGoogle.
Ngokukodwa, ifayile yelayisensi_protcol.proto kunye neWidevine Modular DRM ukuHlanganisela isiKhokelo kunye namaxwebhu e-Widevine DRM Architecture Overview. Kufuneka kuqatshelwe ukuba ilayisensi_protcol.proto yifayile yeheader ye-libprotobuf enenkcazo yesakhiwo seprotocol ye-Widevine, oko kukuthi, i-Google ixoxa ngokusondeleyo kwi-Oracle yokuqiqa ihlasela i-Android.
Kwabo bangayazi itekhnoloji Widevine, Kuya kufuneka bayazi ukuba le nto Iphuhliswa nguGoogle kwaye isetyenziswa ikakhulu kwiChrome nakwiinkqubo ezahlukeneyo (ngokuqhelekileyo kwiLinux) ukukwazi ukubonisa umxholo onelungelo lokushicilela kwiNetflix, Disney, Amazon Video, BBC, HBO, Facebook, Hulu, Spotify kunye nezinye iinkonzo ezininzi.
Imodyuli yeCDM inikezelwe yegama elifanayo ukucacisa umxholo, osetyenziswa kwiChrome, Edge, Firefox kunye ne-Opera, kunye neemveliso ezivela kwi-Samsung, Intel, Sony kunye ne-LG.
Kunyaka ophelileyo, inqanaba elibuthathaka kakhulu lokhuseleko, iWidevine L3, yaqhekeka, yaphunyezwa ngokupheleleyo kwisoftware, kwaye ngokuqhelekileyo isetyenziselwa ukusabalalisa umxholo ongaphantsi kwe-1080p.
Kwavela ukuba i-Whitebox AES-128 i-encryption algorithm yokuphunyezwa iyakwazi ukuhlaselwa kwe-faultal fault analysis (DFA), evumela ukufikelela kwisitshixo se-encryption.
Gqibela, ukuba unomdla wokwazi ngakumbi ngayo Malunga nesicelo esenziwe nguGoogle kwiGitHub, unokujongana neenkcukacha Kule khonkco ilandelayo.
