Kev txhais ntawm MD5 thiab nws cov keeb kwm thiab raug mob
MD5 (technically hu ua MD5 Message-Digest Algorithm ) yog ib qho kev ua hauj lwm cryptographic hash uas nws lub hom phiaj tseem ceeb kom paub tseeb tias cov ntaub ntawv tau hloov kho.
Tsis yog pom zoo tias qhov ob ntawm cov ntaub ntawv yog zoo tib yam los ntawm kev muab cov ntaub ntawv raw, MD5 ua qhov no los ntawm kev tsim checksum ntawm ob qho tib si, thiab mam li muab cov checksums los xyuas tias lawv yog tib yam.
MD5 muaj qee yam flaws, yog li nws tsis yog pab rau kev siv encryption advanced, tab sis nws zoo kawg nkaus tau siv nws rau cov ntaub ntawv txheem cov ntaub ntawv.
Siv ib qho MD5 Checker los yog MD5 Generator
Microsoft File Checksum Integrity Verifier (FCIV) yog ib qho dawb lub tshuab xam zauv uas tsim tau MD5 checksum los ntawm cov ntaub ntawv tseeb thiab tsis yog cov ntawv nyeem xwb. Saib Xyuas Kev Tshawb Fawb Cov Ntaub Ntawv Hauv Lub Xeev nrog FCIV kom paub siv qhov kev pab cuam no.
Ib qho yooj yim uas tau txais MD5 hash ntawm ib txoj hlua ntawm cov tsiaj ntawv, zauv, thiab cov cim yog nrog Miracle Salad MD5 Hash Generator cuab yeej. Muaj coob tus nyob ua ke, zoo li MD5 Hash Generator, PasswordsGenerator, thiab OnlineMD5.
Thaum siv tib lub hash algorithm, tib yam kev tshwm sim tau tsim. Qhov no txhais tau hais tias koj tuaj yeem siv ib lub laij leb MD5 kom tau MD5 checksum ntawm qee cov ntawv nyeem thiab tom qab siv lub sib txawv MD5 lub laij leb kom tau tib lub ntsiab lus. Qhov no yuav rov qab ua dua txhua lub cuab tam uas ua rau muaj kev checksum raws li MD5 muaj nuj nqi.
Keeb Kwm & Amp; Txoj Haujlwm ntawm MD5
MD5 tau tsim los ntawm Ronald Rivest, tab sis nws tsuas yog nws ib qho ntawm nws peb algorithms.
Thawj hash muaj nuj nqi nws tsim tau MD2 nyob rau hauv 1989, uas tau ua rau 8-ntsis computers. Txawm hais tias MD2 tseem siv, nws tsis yog rau cov kev siv uas yuav tsum tau muaj kev ruaj ntseg siab, txij li nws tau qhia tias nws muaj kev ywj pheej rau ntau yam kev tawm tsam.
MD2 tau hloov los ntawm MD4 nyob rau xyoo 1990. MD4 tau ua rau cov tshuab 32-ntsis thiab tau ceev nrawm dua MD2, tab sis kuj pom tias muaj qhov tsis muaj zog thiab tam sim no xav tias tsis siv dhau los ntawm Internet Engineering Task Force .
MD5 raug tso tawm nyob rau hauv 1992 thiab tseem ua rau cov cav tov 32-ntsis. MD5 tsis yoo sai li MD4, tiam sis nws pom tias yuav muaj kev ruaj ntseg ntau dua MDX cov kev siv yav dhau los.
Txawm tias MD5 muaj kev ruaj ntseg dua MD2 thiab MD4, lwm yam kev ua hauj lwm cryptographic hash, xws li SHA-1 , tau raug pom zoo raws li lwm txoj hauv kev, vim tias MD5 tau pom tias muaj kev ruaj ntseg tsis zoo.
Carnegie Mellon University Software Engineering Engineering muaj qhov no hais txog MD5: "Cov tsim tawm software, Cov Thawj Coj Tsav Xwm, cov tswv hauv lub website, thiab cov neeg siv yuav tsum tsis txhob siv lub MD5 algorithm hauv txhua lub peev xwm. siv ntxiv. "
Xyoo 2008, MD6 tau pom zoo rau Lub Chaw Haujlwm Saib Xyuas Kev Kawm Txuj Ci Tebchaws thiab Technology ua lwm txoj haujlwm rau SHA-3. Koj tuaj yeem nyeem ntxiv txog cov tswv yim no .
Xav paub ntxiv txog MD5 Hash
MD5 hashes yog 128-tshooj ntawm qhov ntev thiab feem ntau pom tshwm hauv lawv 32 tus lej kawg hexadecimal nqi sib npaug. Qhov no yeej muaj tseeb txawm loj npaum li cas los yog tsawg dua cov ntaub ntawv lossis cov ntawv nyeem.
Ib qho piv txwv ntawm qhov no yog qhov value hex 120EA8A25E5D487BF68B5F7096440019 , uas txhais cov ntawv txhais lus dawb yog "Qhov no yog kev sim." Muab ntau cov ntawv nyeem kom nyeem "Qhov no yog ib qho kev sim qhia tias qhov ntev ntawm cov ntawv tsis tseem ceeb." txhais mus rau ib qho txawv ntawm tus nqi tab sis nrog tib lub xov tooj ntawm cov cim: 6c16fcac44da359e1c3d81f19181735b .
Qhov tseeb, txawm tias ib txoj hlua nrog pes tsawg lub cim muaj nqi ntawm d41d8cd98f00b204e9800998ecf8427e , thiab siv ib lub sij hawm ua tus nqi 5058f1af8388633f609cadb75a75dc9d .
MD5 checksums yog ua kom tsis yog-ntxeev siab, txhais tau hais tias koj tsis tuaj yeem saib xyuas cov checksum thiab taw qhia cov ntaub ntawv uas tau muab ntaus thawj. Nrog rau cov uas tau hais, muaj ntau MD5 "decrypters" uas tau tshaj tawm tias muaj peev xwm decrypt tus nqi MD5, tiam sis qhov tseeb tshwm sim yog tias lawv tsim cov checksum rau ntau qhov tseem ceeb thiab ces cia koj saib koj cov checksum hauv lawv cov database kom pom tias lawv muaj ib qho kev ua si uas tuaj yeem qhia koj cov ntaub ntawv qub.
MD5Decrypt thiab MD5 Decrypter yog ob qho cuab yeej pub dawb hauv internet uas tuaj yeem ua tau qhov no tiam sis lawv tsuas ua haujlwm rau cov lus thiab cov nqe lus.
Saib Dab Tsi Yog Checksum? rau ntau cov piv txwv ntawm MD5 checksum thiab qee txoj hauv kev los ua kom muaj ib qho MD5 hash ntawm cov ntaub ntawv.
