Hash ua haujlwm tsis tuaj yeem thim rov qab feem ntau MD5 yog 128-ntsis hash, thiab yog li nws qhia cov hlua, tsis hais ntev npaum li cas, rau hauv 128 ntsis. Pom tseeb yog tias koj khiav txhua txoj hlua ntev, hais tias, 129 khoom, qee qhov ntawm lawv yuav tsum tau hash rau tib tus nqi. … Tsis yog txhua tus hash ntawm ib txoj hlua luv luv tuaj yeem thim rov qab li no.

Yuav ua li cas hash tuaj yeem txiav tawm thiab thim rov qab?

Tsis yog, lawv tsis tuaj yeem decrypted Cov haujlwm no tsis thim rov qab. Tsis muaj kev txiav txim siab algorithm uas ntsuas tus nqi qub rau qhov tshwj xeeb hash. Txawm li cas los xij, yog tias koj siv tus lej zais zais hash ruaj ntseg hashing ces koj tseem tuaj yeem pom tias tus nqi qub yog dab tsi.

Koj puas tuaj yeem thim rov qab SHA256 hash?

SHA256 yog lub luag haujlwm hashing, tsis yog kev ua haujlwm encryption. Qhov thib ob, txij li SHA256 tsis yog kev ua haujlwm encryption, nws tsis tuaj yeem decrypted. Qhov koj txhais tau yog tej zaum thim rov qab. Nyob rau hauv tas li ntawd, SHA256 tsis tuaj yeem thim rov qab vim nws yog ib txoj haujlwm.

Puas hash encryption thim rov qab?

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 lub algorithm tsim kom raug, tsis muaj txoj hauv kev los thim rov qab cov txheej txheem hashing los qhia tus password qub
