Kune avo vasinganzwisise, ikozvino ndinokupai muenzaniso.
Ndinokusuma John. Pakati pevanoda kuchengetedzeka ndiyo imwe yenzvimbo dzakanakisa dzekutanga kana iwe uchitanga munyika ye ethicla kubiridzira. John inowirirana zvinoshamisa neshamwari yedu crunch. Uye chaizvo anotora rondedzero yaanopihwa iye otanga kuyedza musanganiswa kusvikira awana kiyi inogadzirisa password yaari kutsvaga.
Crunch jenareta yemasanganiswa. izvi zvinoreva kuti iwe unogona kutaurira crunch kuti iwe unoda password ine mavara matanhatu, iine ekumusoro uye epazasi mavara mavara uye crunch inotanga kuyedza imwe neumwe ... chimwe chinhu senge:

Inonakidza kwazvo, asi kubva pakuona kwangu kurwisa kwechisimba kurwisa kuri kushaya basa, uye kugadzirwa kwemaphassword akadai se "ElQuijoteDeLaMancha1" hairatidzike semhinduro inoshanda futi, izvi imhaka yekuti neinjiniya diki inokwanisika kuwana maPassword e rudzi urwu, rwakakura chete nekutsvaga zvepamusoro munhu uye iye achazotizarurira, kungave mumasocial network, kune vaanozivana navo kana kubasa, chikamu chehunhu hwevanhu.
Mukuona kwangu, mhinduro yakanakisa ndeye kushandisa password maneja, nekuti zvakachengeteka kushandisa password ine manhamba zana pane iyo ine manhamba makumi maviri, pamusoro pezvo, pane mukana wekuti sezvo tenzi password ichingozivikanwa, hazvigoneke kuburitsa kunyangwe kumadokero mapassword akagadzirwa nekuti haazivikanwe.
Iyi ndiyo password yangu maneja, yakavhurwa sosi uye nekuteedzera keyboard, haina hutachiona kuma keyloger.

Zvakanaka, handizvinyepere kupa mhinduro isina njodzi zvachose (ndichiyeuka kuti hapana chinhu zana chisingapindike) mumazwi 100 chete 🙂 (Ini handidi kunyora zvinopfuura izvozvo kunze kwekunge zvichinyatso kudikanwa) asi sekutaura kwako izvozvo 1500 irinani kupfuura makumi maviri, tsime makumi maviri zvirinani kupfuura 100 well uye, sezvatakambotaura pakutanga, chisina kusimba chinongedzo ndiye murume, saka ndipo panotariswa nguva dzose.
