MD5 (tshwj xeeb hu ua MD5 Message-Digest Algorithm) yog cryptographic hash muaj nuj nqi uas nws lub hom phiaj tseem ceeb yog los xyuas kom meej tias cov ntaub ntawv tsis raug hloov pauv.
Siv tsis lees paub ob pawg ntawm cov ntaub ntawv zoo ib yam los ntawm kev sib piv cov ntaub ntawv nyoos, MD5 ua qhov no los ntawm kev tsim cov ntawv txheeb xyuas ntawm ob pawg thiab tom qab ntawd sib piv cov checksums kom paub tseeb tias lawv zoo ib yam.
MD5 muaj qee qhov tsis zoo, yog li nws tsis muaj txiaj ntsig rau kev siv encryption siab heev, tab sis nws zoo kawg nkaus siv nws rau cov ntaub ntawv pov thawj tus qauv.
Siv MD5 Checker lossis MD5 Generator
Microsoft File Checksum Integrity Verifier (FCIV) yog ib lub tshuab xam zauv pub dawb uas tuaj yeem tsim MD5 checksum los ntawm cov ntaub ntawv tiag tiag thiab tsis yog ntawv xwb. Saib peb tsab xov xwm hais txog yuav ua li cas txheeb xyuas cov ntaub ntawv ncaj ncees hauv Windows nrog FCIV kom kawm paub siv cov kab lus hais kom ua li cas.
Ib txoj hauv kev yooj yim kom tau txais MD5 hash ntawm ib txoj hlua ntawm cov ntawv, cov lej, thiab cov cim yog nrog Miracle Salad MD5 Hash Generator cov cuab yeej. Ntau lwm tus kuj tseem muaj, xws li MD5 Hash Generator, PasswordsGenerator, thiab OnlineMD5.
Thaum siv tib lub hash algorithm, tib cov txiaj ntsig tau tsim. Qhov no txhais tau tias koj tuaj yeem siv ib lub tshuab xam zauv MD5 kom tau txais MD5 checksum ntawm qee cov ntawv nyeem thiab tom qab ntawd siv lub tshuab xam zauv MD5 sib txawv kom tau txais cov txiaj ntsig zoo ib yam. Qhov no tuaj yeem rov ua dua nrog txhua lub cuab yeej uas tsim cov tshev nyiaj raws li qhov kev ua haujlwm hash.
History and Vulnerabilities of MD5
MD5 tau tsim los ntawm Ronald Rivest, tab sis nws tsuas yog ib qho ntawm nws peb lub tswv yim.
thawj hash muaj nuj nqi nws tsim yog MD2 hauv 1989, uas tau tsim rau 8-ntsis computers. Txawm hais tias nws tseem siv tau, MD2 tsis yog rau cov ntawv thov uas xav tau kev ruaj ntseg siab, vim nws tau pom tias muaj kev cuam tshuam rau ntau yam kev tawm tsam.
MD2 ces tau hloov los ntawm MD4 hauv xyoo 1990. MD4 tau tsim rau 32-ntsis tshuab thiab tau nrawm dua MD2, tab sis kuj tau pom tias muaj qhov tsis muaj zog thiab tam sim no suav tias tsis siv los ntawm Internet Engineering Task Force.
MD5 tau tso tawm xyoo 1992 thiab tseem tau tsim rau 32-ntsis tshuab. Nws tsis yog nrawm li MD4 tab sis nws tau pom tias muaj kev nyab xeeb dua li qhov kev siv MDx yav dhau los.
Txawm hais tias MD5 muaj kev nyab xeeb dua li MD2 thiab MD4, lwm yam kev ua haujlwm cryptographic hash, zoo li SHA-1, tau raug pom zoo ua lwm txoj hauv kev, txij li MD5 kuj tau pom tias muaj qhov tsis zoo ntawm kev ruaj ntseg.
Carnegie Mellon University Software Engineering lub koom haum muaj qhov no hais txog MD5:
Software developers, Certification Authority, website tswv, thiab cov neeg siv yuav tsum tsis txhob siv MD5 algorithm nyob rau hauv txhua lub peev xwm. Raws li kev tshawb fawb yav dhau los tau pom, nws yuav tsum raug suav tias yog cryptographically tawg thiab tsis tsim nyog rau kev siv ntxiv.
MD6 tau raug qhia rau National Institute of Standards and Technology ua lwm txoj rau SHA-3. Koj tuaj yeem nyeem ntxiv txog qhov kev thov no ntawm no.
Xav paub ntxiv ntawm MD5 Hash
MD5 hashes yog 128-ntsis ntev thiab feem ntau pom nyob rau hauv lawv 32-tus lej hexadecimal tus nqi sib npaug. Qhov no muaj tseeb txawm tias cov ntaub ntawv loj lossis me me npaum li cas.
Nov yog ib qho piv txwv:
- Plain text: Nov yog kev xeem.
- Hex tus nqi: 120EA8A25E5D487BF68B5F7096440019
Thaum cov ntawv sau ntxiv, tus hash txhais ua qhov sib txawv tag nrho tab sis nrog cov cim tib yam:
- Plain text: Nov yog ib qhov kev sim qhia seb qhov ntev ntawm cov ntawv tsis muaj teeb meem.
- Hex tus nqi: 6c16fcac44da359e1c3d81f19181735b
Qhov tseeb, txawm tias ib txoj hlua nrog xoom cim muaj tus nqi hex ntawm d41d8cd98f00b204e9800998ecf8427e, thiab siv txawm tias ib lub sijhawm ua rau tus nqi no: 5058f1af8388633f609d7db.

MD5 checksums yog tsim los tsis yog thim rov qab, txhais tau tias koj tsis tuaj yeem saib daim tshev thiab txheeb xyuas cov ntaub ntawv sau thawj zaug.
Piv txwv, txawm a= 0cc175b9c0f1b6a831c399e269772661 thiab p=83878c91171338902e0fe0fb97a8c47a , sib txuas ob qho los ua ap ua kom sib txawv thiab tsis sib xws: 62c428533830d84fd8bc77tf2c428533830d84fd8bc77 los qhia ib tsab ntawv.
Nrog qhov tau hais, muaj ntau MD5 "decrypters" uas tau tshaj tawm tias muaj peev xwm decrypt tus nqi MD5.
Txawm li cas los xij, qhov tshwm sim tiag tiag nrog tus decryptor, lossis "MD5 rov qab hloov pauv," yog tias lawv tsim cov checksum rau ntau qhov txiaj ntsig thiab tom qab ntawd cia koj saib koj cov checksum hauv lawv cov ntaub ntawv los saib seb lawv puas muaj qhov sib tw. tuaj yeem qhia koj cov ntaub ntawv qub.
MD5Decrypt yog cov cuab yeej online dawb uas ua haujlwm raws li MD5 rov qab saib, tab sis nws tsuas yog ua haujlwm rau cov lus thiab kab lus.
Saib Checksum yog dab tsi? rau cov piv txwv ntxiv thiab qee txoj hauv kev pub dawb los tsim tus nqi MD5 hash los ntawm cov ntaub ntawv.
