Nyob rau hauv tas li ntawd, cov passwords tseem ceeb heev koj xav tau ib txoj kev ruaj ntseg khaws passwords. bcryptjs cia koj hash koj cov passwords txhais tau tias nws hloov koj tus password rau ib txoj hlua random.
Hauv qhov no, Saltrounds yog dab tsi?
Bcrypt yog ib qho kev hloov pauv lo lus zais hashing muaj nuj nqi: dhau sijhawm, cov lej suav tuaj yeem nce ntxiv kom qeeb qeeb, yog li nws tseem tiv taus qhov kev tshawb nrhiav brute-force tawm tsam txawm tias muaj zog suav ntxiv.
Tsis tas li ntawd, ntsev Bcrypt yog dab tsi? (Kawm yuav ua li cas thiab thaum twg thiaj li tshem tawm cov lus qhia no) Hauv cryptography, a ntsev yog cov ntaub ntawv random uas yog siv los ua ib qho kev tawm tswv yim ntxiv rau ib qho kev ua haujlwm uas hashes cov ntaub ntawv, tus password lossis passphrase. Ntsev yog siv los tiv thaiv tus password hauv kev cia.
Tom qab ntawd, lo lus nug yog, Bcrypt piv ua haujlwm li cas?
Cov ntsev yog muab tso rau hauv lub hash (raws li cov ntawv dawb). Cov piv muaj nuj nqi tsuas yog rub cov ntsev tawm ntawm lub hash thiab tom qab ntawd siv nws los hash tus password thiab ua qhov kev sib piv.
Bcrypt puas tuaj yeem decrypted?
Koj ua tsis tau decryption hash khaws cia los ntawm bcrypt . Hashing zoo li hlawv ib daim ntawv. Koj ua tau hloov daim ntawv rau tshauv los ntawm kev hlawv nws tab sis koj tsis tuaj yeem thim rov qab.

Dab tsi yog tus sawv cev heuristic Dab tsi yog qhov muaj heuristic?
Qhov muaj heuristic yog ib txoj kev puas siab puas ntsws uas pab peb txiav txim siab raws li nws yooj yim npaum li cas los coj ib yam dab tsi rau hauv siab. Tus neeg sawv cev heuristic yog ib txoj kev puas siab puas ntsws uas pab peb txiav txim siab los ntawm kev sib piv cov ntaub ntawv rau peb cov qauv kev puas hlwb
Daim ntawv teev kev sib pauv yog dab tsi thiab nws txoj haujlwm yog dab tsi?
Daim ntawv teev kev lag luam yog cov ntaub ntawv sib txuas ntawm txhua qhov kev hloov pauv hauv cov ntaub ntawv thaum cov ntaub ntawv tiag tiag muaj nyob rau hauv cov ntaub ntawv sib cais. Daim ntawv teev kev lag luam muaj cov ntaub ntawv txaus los tshem tawm tag nrho cov kev hloov pauv tau ua rau cov ntaub ntawv cov ntaub ntawv ua ib feem ntawm ib qho kev sib pauv
