Kungani Amakhodi e-TOTP Ehluleka Lapho Iwashi Ledivayisi Liphambuka

Amakhodi asetshenziswa kanye angase abe nokulunga okuphelele ocingweni lwakho futhi iseva iwalahle ngalo kwalowo mzuzu. Izinhlangothi zombili zibala umsebenzi ofanayo kusuka emfihlweni owabiwe kanye nesinyathelo sesikhathi samanje, ngakho ukungavumelani ngesikhathi kudala ukungavumelani ngekhodi. Lokho kwenza ukuphambuka kwewashi kube yiphutha elibalulekile kwezokuphepha hhayi nje ukuphazamiseka.

Amawashi amabili abalulekile lapha, futhi ukulungisa owubonakalayo ingxenye abantu abayenza kuqala. Lowo ovame ukudinga ukunakwa ngomunye.

Ikhodi ingumsebenzi wesikhathi, hhayi iphasiwedi

I-TOTP ithatha imfihlo eyabiwe kanye nesibali esithathwe esikhathini samanje, idlulisa kokubili ku-hash enokhiye futhi inciphisa umphumela ube uchungechunge olufushane lwedesimali, njengoba kucacisiwe ku- RFC 6238. Isibali siqhubekela phambili esinyathelweni ngasinye sesikhathi, ngokuvamile imizuzwana engamashumi amathathu, ngakho imfihlo efanayo ikhiqiza inani elisha lapho isinyathelo sishintsha. Isiqinisekisi sibala kabusha inani elilindelekile lesinyathelo samanje futhi siqhathanise, okudinga imfihlo efanayo kanye nombono ofanayo wamanje. Iphasiwedi ihlala isetshenziswa kabusha kuze kube ishintshiwe, kuyilapho leli nani liphelelwa yisikhathi emngceleni isekheli elingakwazi ukuwubona.

Yingakho ikhodi eyodwa isebenza futhi elandelayo yehluleka ngemizuzwana embalwa kamuva. Lokhu futhi kuchaza ukuthi kungani ukukopisha ikhodi kumlayezo wengxoxo kuwumkhuba ongathembekile kangaka.

Amawashi amabili kufanele avumelane, hhayi elilodwa

Impahla yokubhalisa iyinto yokuqala eyabiwe, futhi isikhathi siyinto yesibili. Uma imfihlo ilungile kuyilapho amawashi ehluka ngaphezu kwewindi elivunyelwe, inani ngalinye elikhiqiziwe liwela esinyathelweni esingalungile futhi liyenqatshwa. Uma amawashi evumelana kuyilapho imfihlo ingalungile, inani ngalinye liyenqatshwa futhi, futhi kokubili ukwehluleka kubonakala kufana kusukela kusikrini sokungena. Ukuhlukanisa kusho ukuhlola umbhalo we-akhawunti kanye nesikhathi ngokwahlukana, ngalolo hlelo.

Iwashi lesiqinisekisi lifanele ukuhlolwa okufanayo njengelwedivayisi. Iseva umthombo wayo wesikhathi owephukile inqaba amakhodi alungile awo wonke abasebenzisi ngesikhathi esisodwa, futhi imibiko izochaza ukuphazamiseka okungazelelwe hhayi ukuphambuka. Leli phethini lifanele laziwe, ngoba ukulungiswa kwalo kuseva hhayi kumafoni ayikhulu.

Kubiza ini ukwandisa iwindi

Ukuqaliswa kungase kwamukele ikhodi esinyathelweni esiseduze ukuze kumunce umehluko omncane, futhi lokho kubekezelela kuyisinqumo somklamo, hhayi ukulungisa kwamahhala. Isinyathelo ngasinye esengeziwe siphindaphinda inani lamavelu avumelekile nganoma yisiphi isikhathi, okuyiyo kanye into ethandwa umhlaseli oqagelayo. Umthetho wokulwa nokuphindaphinda ubalulekile ngesizathu esifanayo, ngoba ikhodi eyamukelwa kabili iyikhodi evuzile ngendlela ewusizo. Umphathi owandisa iwindi ukuze athulise izikhalazo ushintsha impahla yangempela ngokuthuthuka kwangaphandle.

Ukulungisa iwashi ukulungisa, kuyilapho ukwandisa iwindi kuyisithambisi. Okokuqala kususa imbangela futhi okwesibili kuyifihla.

Hlola amawashi womabili ngaphambi kokuzama futhi

Funda isikhathi kudivayisi nakuseva, futhi qhathanisa ukwehluka esikhundleni sezikhathi zendawo ezibonisiwe. Imiyalo engezansi ikhombisa isimo sokuvumelanisa kanye nomzuzu we-UTC ongahluziwe kumphathi noma kuseva ye-Linux. Yisebenzise emaphethelweni womabili ngaphambi kokushintsha noma yisiphi isilungiselelo sokuqinisekisa.

Ukwehluka okukalwa ngemizuzwana akunangozi, okukalwa ngamaminithi kuchaza ukwenqatshwa, futhi uhlelo olungabiki noma yimuphi umthombo wokuvumelanisa luyisifakiswa sakho kokubili. Qhathanisa izigxivizo zesikhathi ze-UTC ezimbili ngqo, ngoba isikhathi sendawo sihlanganisa isifunda sesikhathi i-algorithm engakaze isibone. Uma ukwehluka kukuncane futhi amakhodi asehluleka, yeka ukulungisa amawashi bese uhlola umbhalo wokubhalisa esikhundleni salokho. Imizamo ephindaphindiwe yokumelana ne-akhawunti evaliwe yenza kube nzima ukubona iphutha lokuqala.

Rekhoda isikhathi sokwenqatshwa, ukwehluka kanye nombhalo wephutha, futhi ushiye imfihlo eyabiwe ngaphandle kwalokho. Ukusekelwa kungasebenza ngezinto ezintathu zokuqala futhi akufanele neze kubone eyesine.
