Ifayile encryption

OluNgabonakaliyo Ifayile ikuvumela ukuba wongeze enye umaleko wokhuseleko, kanjalo anike isiqinisekiso ukuba ifayile iya efundwayo kuphela umdali wayo. Ukuba into ziya kuvulwa nguye nawuphi na umsebenzisi, nokuba inkululeko ngamalungelo ophatho, ngoko screen engabhalwanga okanye iseti engamampunge zabalinganiswa kuya kuvela phambi kwakhe. Ngamanye amazwi, i data zombhalo ayikwazi ukufunda, ngaphandle kokuba sisebenza inkqubo phantsi-akhawunti yakho. Cinga imicimbi enxulumene banzi.

Ukubethela iifayile kunye neencwadi ezinenkcukacha yindlela elula kakhulu ekukhuseleni ulwazi oluyimfihlo. Kodwa ukuba data ingafihlwanga kwaye wayifihla iya kugcinwa kwi idiskhi, oko kunokubangela iziphumo engalindelekanga.

Kuba abasebenzisi Windows 7, kukho isixhobo esisodwa, leyo kuthiwa uNgqamaniso lwendawo. Esi sicelo ihambisa lonke ulwazi ukusuka disk ukuya kwenye ifayile enkulu, umnxeba apho kwixesha elizayo iyafana nje virtual hard disk. Ukuba uye umqhubi kwenkqubo yokusebenza iifayile yoguqulelo, i-encryption khowudi yasiwa kumbhalo nkqubo lwenzeka kwi ngasemva, oko kukuthi, nina ukuqonda. Inzuzo enkulu lwenkqubo BitLocker kukuba inika ufihlo lwefayile (kunye nenkqubo ngokunjalo), yaye oku kwenza kube nzima ukuzivula igama, kwakunye imvume yokungena inkqubo esuka ngaphandle. Ukuba ukubethela yonke drive, akukho mfuneko yokuba yeekhowudi iifayile ngamnye.

Disk ukubethela kuyimfuneko ukuvula iphepha "lwendawo yeDiskhi yeBitLocker" kule nkqubo - ukuba ibekwe kwi panel yolawulo. Ukuba umyalezo kubonakala kuwe ukuba TPM alafunyanwa, ngoko ufuna ukukhangela ukuba icomputer yakho ngenxa efanelekileyo update BIOS exhasa TPM.

TPM i chip ukwakweli motherboard apho BitLocker iqhosha elizinyelisiweyo, nto leyo evumela ikhompyutha ukwenza kokuqala ukusuka diski zombhalo. Ukuba BIOS akaxhasi TPM, esiqhelekileyo USB-drive kakhulu unako ukukhonza chip. Umsebenzisi akufuneki uphawu kuphela ifayile njengebanjelwe ukuba encryption, kwaye inkqubo yokusebenza iza kwenza ukusebenza encryption khowudi yasiwa kumbhalo kwisiqalo xa kukho indalo, okanye ukujonga ifayile. Ngamanye amaxesha le hlobo izimanga ufihlo ukuba ayihambisani ukhuseleko esiphezulu.

Ukubethela iifayile umsebenzi we inkqubo lwefayile NTFS, leyo kwezinye iindlela zefayile nje ayifumaneki. Ithi ukopishe le fayile obubhalwe ukuya drive USB okanye CD-ROM akayi uguqulwa, ekubeni ezi zixhobo musa ukuxhasa le nkqubo lwefayile.

Ifayili ufihlo: ulandelelwano lweentshukumo

Xa sithetha nge-Windows 7, apha kukho ulandelelwano olulula kakhulu kwaye ubhalo yezenzo yomsebenzisi, ngokusivumela ukuba afumane iziphumo ezinqwenelekayo.

Okokuqala kufuneka kulungiswe-nqakraza kwi iifayile eneqikili efunekayo kwi Windows Explorer, uze ukhethe ukusuka iipropati into umxholo menu. Kwi "General" tab, khetha i "resp". Emveni kwezi zazo kwi window evulayo, kufuneka ubeke uphawu "imixholo anini ukukhusela data". Emva u- "OK" zonke utshintsho uzakuthatha isiphumo.

Njengoko kwakunye naliphi na inyathelo, oku kuthetha iindlela ufihlo ethile. Kule meko sithetha ngayo indlela kwinkqubo yokufumana iifayile yoguqulelo. Ngokuba izinto ezinjalo akulungile ukusebenzisa iqhosha zokufihlakeleyoComment, kwakunye nezinye iindlela eziliqela.

ufihlo olungundoqo yi algorithm apho iqhosha yaziwa kuphela umthumeli umamkeli. Encryption twatsa usebenzisa ukuba ngemfihlo kwaye ukungafihli isitshixo efanayo. Encryption yezi kukusebenzisa i isitshixo uluntu ukuba ngemfihlo kwaye zivaliwe - for kubhalo.
