Thaum kawg, hashing yog daim ntawv ntawm kev ruaj ntseg cryptographic uas txawv ntawm kev nkag mus. Whereas encryption yog ob kauj ruam txheej txheem siv thawj zaug encrypt thiab tom qab ntawd decrypt cov lus, hashing condenses ib cov lus rau hauv ib qho irreversible taag-ntev tus nqi, los yog hash.
Puas hashing encryption?
Hashing yog txheej txheem kev encryption ib-txoj kev xws li tus nqi hash tsis tuaj yeem thim rov qab kom tau txais cov ntawv qub qub. Hashing yog siv hauv encryption kom ruaj ntseg cov ntaub ntawv sib koom ntawm ob tog. Cov passwords tau hloov pauv mus rau qhov muaj nuj nqis hash kom txawm tias muaj kev nyab xeeb txhaum cai tshwm sim, PINs nyob ruaj khov.
Puas yog encryption thiab hashing tib yam?
Kev nkag mus yog ob txoj haujlwm; dab tsi yog encrypted tuaj yeem decrypted nrog tus yuam sij kom raug. Hashing, txawm li cas los xij, yog ib txoj hauv kev ua haujlwm uas sib sau cov ntawv dawb los tsim cov lus tshwj xeeb digest. Nrog rau kev tsim cov algorithm kom zoo, tsis muaj txoj hauv kev los thim rov qab cov txheej txheem hashing los qhia tus password qub.
Puas hashing ib daim ntawv ntawm cryptography?
Hashing yog txheej txheem ntawm cryptography uas hloov txhua hom ntaub ntawv rau hauv ib txoj hlua tshwj xeeb ntawm cov ntawvIb qho ntawm cov ntaub ntawv tuaj yeem hashed, txawm nws loj lossis hom. Hauv ib txwm hashing, tsis hais cov ntaub ntawv loj npaum li cas, hom, lossis ntev, qhov hash uas cov ntaub ntawv tsim tawm yog qhov ntev tib yam.
Vim li cas hashing tsis suav tias yog txoj kev encryption tiag tiag?
Hash lub luag haujlwm raug suav tias yog hom kev encryption ib-txoj kev vim cov yuam sij tsis sib koom thiab cov ntaub ntawv xav tau los thim rov qab encryption tsis muaj nyob hauv cov zis.
