Yuav ua li cas decrypt tus hash? Lub hauv paus ntsiab lus ntawm hashing tsis yog yuav tsum tau thim rov qab, tsis muaj decryption algorithm, yog vim li cas nws yog siv los khaws cov passwords: nws yog khaws cia encrypted thiab tsis unhashable. … Tib txoj kev los decrypt ib tug hash yog kom paub cov input data.
Tus hash puas tuaj yeem thim rov qab?
Hash ua haujlwm tsis yog rov 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, 129 khoom, qee qhov ntawm lawv yuav tsum tau hash rau tib tus nqi.
Tus nqi hash puas tuaj yeem decrypted?
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.
Yuav puas tau tawg?
Hashes tuaj yeem tawg tau siv brute forcing Qhov no txhais tau tias koj sim hashing txhua qhov kev tawm tswv yim kom txog thaum koj pom ib qho uas tsim cov khoom tsim nyog. Txhawm rau kom tsis txhob muaj qhov hash muaj nuj nqi siv rau lo lus zais cia lossis qhov tseem ceeb derivation yuav tsum txhob txwm maj mam qeeb (yog li ntawd qhov kev sim ntau ntawm cov tswv yim siv sijhawm ntev heev).
Tus hash puas tuaj yeem decrypted kom rov qab tau cov ntaub ntawv qub?
Cryptographic hashes (MD5, thiab lwm yam …) yog ib txoj hauv kev thiab koj tsis tuaj yeem rov qab mus rau cov lus qub nrogtsuas yog qhov digest tshwj tsis yog koj muaj qee cov ntaub ntawv hais txog tus thawj lus, thiab lwm yam uas koj yuav tsum tsis txhob. Decryption (ncaj qha tau cov ntawv dawb los ntawm tus nqi hashed, hauv txoj kev algorithmic), tsis yog.
