Kae-kae ka 2014, lithakong tsa sefate sa mohloli oa BSD 3, ke fumane faele e nang le li-password tsa bahlabani bohle ba kang Dennis Ritchie, Ken Thompson, Brian W. Kernighan, Steve Bourne le Bill Joy.
Algorithm e sebelisitsoeng bakeng sa li-hashes tsena e ne e le DES-based - e tsebahala e fokola (mme e na le password ea bolelele ba litlhaku tse 8). Kahoo ke ne ke nahana hore ho tla ba bonolo ho qhekella li-password tsena bakeng sa monate.
Re nka li-bruters tse tloaelehileng и .
Ka potlako ke ile ka hlakola li-password tse ngata, tseo bongata ba tsona li neng li fokola haholo (ho khahlisang ke hore bwk o sebelisitse password. /.,/.,, - ho bonolo ho e ngola ho keyboard ea QWERTY).
Empa password ea Ken e ne e sa hlake. Esita le patlisiso e feletseng ea litlhaku tse nyenyane le linomoro (matsatsi a 'maloa ka 2014) ha ea ka ea hlahisa liphello. Kaha algorithm e entsoe ke Ken Thompson le Robert Morris, ke ne ke ipotsa hore na taba e kholo ke efe. Ke ile ka boela ka hlokomela hore, ha ho bapisoa le merero e meng ea password hashing joaloka NTLM, crypt(3) e lieha ho senya (mohlomong e fokotsehile haholo).
A tota o ne a dirisa ditlhaka tse dikgolo kana ditlhaka tse di kgethegileng? (7-bit e tletseng matla a sehlōhō e tla nka lilemo tse fetang tse peli ho GPU ea morao-rao).
Mathoasong a Mphalane sehlooho sena lethathamong la mangolo , le ke le ho soaba hore ebe ha a khone ho hlakola phasewete ea Ken.
