Hashed data maps tus thawj hlua ntawm cov cim rau cov ntaub ntawv ntawm qhov ntev. Ib qho algorithm tsim cov ntaub ntawv hashed, uas tiv thaiv kev ruaj ntseg ntawm cov ntawv qub.
Tus nqi txhais li cas?
A tus nqi hash yog tus lej tus nqi ntawm qhov ntev ruaj khov uas txheeb xyuas cov ntaub ntawv. Hash qhov tseem ceeb sawv cev rau cov ntaub ntawv loj npaum li cov lej me me, yog li lawv siv nrog cov kos npe digital. … Cov txiaj ntsig Hash kuj tseem muaj txiaj ntsig rau kev txheeb xyuas qhov tseeb ntawm cov ntaub ntawv xa mus los ntawm cov channel tsis ruaj ntseg.
Dab tsi yog hashed neeg cov ntaub ntawv?
Hashing yog hom kev ruaj ntseg cryptographic uas hloov cov ntaub ntawv hauv koj cov neeg siv khoom rau hauv randomized code. … Cov txheej txheem tsis tuaj yeem thim rov qab.
Yuav ua li cas nrog piv txwv?
Hashing yog cov ntaub ntawv tseem ceeb tsim los daws qhov teeb meem ntawm kev nrhiav tau zoo thiab khaws cov ntaub ntawv hauv ib qho array. Piv txwv li, yog tias koj muaj cov npe ntawm 20000 tus lej, thiab koj tau muab tus lej los tshawb hauv cov npe ntawd- koj yuav luam theej txhua tus lej hauv daim ntawv kom txog thaum koj pom qhov sib tw.
Nyob ntsev thiab hashing yog dab tsi?
