Ukulayisha kubonakala kukhonzile: qhathanisa ama-hash kuzo zombili iziphetho

Abamukeli abangakwazi ukuvula ifayela elilayishiwe bavame ukuzwa ukuthi i-VPN ililimazile. Lokho kuwumbono nje, hhayi ukubona, futhi kuyahlolwa. Ngaphambi kokuthinta umhubhe, thola ukuthi into egcinwe manje endaweni ekuyiwa kuyo ihlukile yini entweni obekufanele ithunyelwe. Konke okunye kulandela leyo mpendulo.

Qala ngamabhayithi obekuhlosiwe, hhayi ngesikhalo

Khetha ifayela elingenabungozi eliphindisa inkinga, noma ifayela langempela uma inqubomgomo ivuma ukuthi liphume endaweni yomthombo. Bhala phansi izinto ezimbili ngaphambi kokudlulisa: usayizi oqondile ngamabhayithi kanye ne-hash yokuqukethwe yesimanje. Amagama amafayela, izimpawu zesikhathi kanye nokubuka kuqala kuyi-metadata, futhi akukho kukho okukhomba okuqukethwe.

Bala i-hash nge-algorithm engasetshenziswa yiziphetho zombili, futhi bhala ukuthi isiphi osisebenzisile. Ukuqhathanisa phakathi kwe-SHA-256 ne-MD5 akulona ukuqhathanisa, futhi nokuqhathanisa phakathi kwamafayela amabili ahlukene avumelana ngegama ngengozi nakho akulona ukuqhathanisa.

PS> Get-FileHash -LiteralPath "C:\uploads\report.csv" -Algorithm SHA256
Hash                                                        Path
----                                                        ----
9F2C...                                                      C:\uploads\report.csv

Isithenjwa se-Get-FileHash sakwa-Microsoft ibhala phansi umyalo kanye nepharamitha ye-algorithm yawo, okuyiyona ngxenye abantu abayeqayo lapho ukuqhathanisa kuveza ukungafani okungenanjongo.

I-hash eyodwa esigabeni ngasinye, i-algorithm efanayo

Manje bala i-algorithm efanayo entweni egciniwe lapho igcina khona, ngendlela evunyelwe hhayi ngekhophi edlule kwenye ithuluzi. Ukugcina ifayela elitholiwe endaweni yakho nokwenza i-hash yaleyo khophi kunezela isinyathelo ongakahloli.

Uma insizakalo iveza eyayo inani lobuqotho, yithathe njengokubona okuhlukile. Isamba sokuhlola esibikwa umhlinzeki singakutshela ukuthi umhlinzeki ucabanga ukuthi ugcine ini, futhi lokho akusona isitatimende esifanayo nalokho okuthunyelwe iklayenti lakho.

Imiphumela emithathu ingenzeka, futhi ikhomba izinhlangothi ezahlukene. Ama-hash alinganayo asho ukuthi amabhayithi afike engashintshile. Ama-hash ahlukene anokuguqulwa okwaziwayo asho ukuthi insizakalo idale into entsha ngamabomu. Ama-hash ahlukene ngaphandle kokuguqulwa asho ukuthi okuthile phakathi kwamaphoyinti amabili kushintshe okuqukethwe, futhi isinyathelo esilandelayo ukuthola umngcele wokuqala lapho lokho kwenzeka khona.

Hlukanisa ukwehluleka kokudlulisa nokuguqulwa

Ukulayisha okuyingxenye nokulayisha okukhonzile kubonakala kufana kusiphequluli samafayela futhi kuyiziphambeko ezahlukene. Hlola ukuthi ukudlulisa kuqedile yini: ilogi yohlelo ekhombisa isicelo esinqanyuliwe, ifayela eligciniwe elinosayizi oyisiqalo somthombo, noma into empeleni eyikhasi lephutha eligcinwe ngaphansi kwesandiso obekulindelekile, konke kukhombisa ukudlulisa okungaphelele hhayi amabhayithi ashintshiwe.

Ukuguqulwa kungenye incazelo evamile. Insizakalo ecindezela kabusha izithombe, ebhala kabusha iziphetho zemigqa ye-CSV noma eguqula idokhumenti izokhiqiza ngokusemthethweni i-hash ehlukile kowomthombo, futhi lokho akukona ukukhonza. Qhathanisa isigaba esithi siyikhophi ethembekile, hhayi ifomethi yokwethulwa yokugcina.

Ukubambezeleka nokulahleka kungokwesigaba sesithathu. Kungabangela iklayenti ukuthi liphelelwe isikhathi, lizame futhi noma lilahle ithemba, futhi akukho kulokho okusho ukuthi amabhayithi amukelwe iseva ashintshwa ngasese. Bheka umphumela wokudlulisa ngaphambi kokuthi unikeze umhubhe icala.

Zama indlela yesibili ngaphandle kokushintsha konke

Uma ama-hash ehluke ngempela futhi kungekho kuguqulwa, phinda ifayela elifanayo, iklayenti, iphrothokholi nendawo ekuyiwa kuyo ngendlela enye esekelwayo, njengenethiwekhi yasendaweni esikhundleni se-VPN. Shintsha uhlobo olulodwa. Ukushintsha iklayenti, iphoyinti lokugcina nethuluzi ngesikhathi esisodwa kukunika umphumela ongakwazi ukuwunikeza.

Gcina ukuqhathanisa kuyikho okwethembekile kuzo zombili izinhlangothi. I-hash ikutshela ukuthi amaphoyinti amabili awavumelani noma ayavumelana ngokuqukethwe; ayikutsheli ukuthi yiluphi uhlangothi oluthembekile, ngakho gcina inani obekulindelekile nokuqinisekisa ngaphakathi kwemodeli yokwethemba osethembile ngayo ngempela.

Qedela ngumusho othile kwithikithi: ukudlulisa kwama ngaphambi kwesikhathi, uhlelo lwashintsha into, isitoreji sayishintsha, noma amabhayithi ayavumelana futhi ukuwafunda ukwehluleka. Ngakunye kwalokho kunomnikazi ohlukile, futhi akukho kulokho okuyi-VPN ngokuzenzakalela.
