MD5 ndi chiyani?

MD5 imayimira "Message Digest 5" ndi njira yachinsinsi yopangidwa ndi Pulofesa Ron Rivest mu 1991. Chifukwa cha MD5, imapanga mawu anjira imodzi polemba zolemba zilizonse zautali uliwonse kukhala chala cha 128-bit. Chifukwa cha njirayi, mawu achinsinsi sangathe kusindikizidwa ndipo chitetezo cha deta yobisika chikuwonjezeka kwambiri. Ngakhale kutalika kwa data kumatha kulowetsedwa mu MD5, zotsatira zake ndi kutulutsa kwa 128 bits.

Kugawa deta mu magawo 512-bit, MD5 imabwereza ntchito yomweyo pa chipika chilichonse. Chifukwa chake, zomwe zidalowetsedwa ziyenera kukhala 512 bits ndi ma multiples ake. Ngati sichoncho, palibe vuto, MD5 imamaliza ntchitoyi yokha. MD5 imapereka mawu achinsinsi a manambala 32. Kukula kwa deta yomwe yalowetsedwa sikofunikira. Kaya ndi manambala 5 kapena manambala 25, kutulutsa kwa manambala 32 kumapezeka.

Jenereta ya algorithm ya MD5 ndiyothandiza posunga mawu achinsinsi, manambala a kirediti kadi, ndi zina zambiri masiku odziwika bwino m'malo osungira monga MySQL. Ndi chida chothandiza pa intaneti makamaka kwa PHP, ASP opanga mapulogalamu ndi opanga omwe amagwiritsa ntchito nkhokwe monga MySQL, SQL, MariaDB, Postgress. Kuyika chingwe chomwecho pogwiritsa ntchito MD5 algorithm nthawi zonse kumabweretsa zotsatira zofanana za 128-bit algorithm. Ma algorithms a MD5 nthawi zambiri amagwiritsidwa ntchito ndi zingwe zing'onozing'ono posunga mawu achinsinsi, manambala a kirediti kadi kapena zidziwitso zina m'madatabase monga MySQL yotchuka. Chida ichi chimapereka njira yachangu komanso yosavuta yosinthira ma aligorivimu a MD5 kuchokera pachingwe chosavuta mpaka zilembo 256 zazitali.

Ma algorithms a MD5 amagwiritsidwanso ntchito kutsimikizira kukhulupirika kwa mafayilo. Chifukwa ma aligorivimu a MD5 algorithm nthawi zonse amatulutsa zotulutsa zomwezo kuti alowemo, ogwiritsa ntchito amatha kufananiza mtengo wa algorithm ya fayiloyo ndi mtengo wa algorithm yomwe fayiloyo wapanga kumene kuti awone ngati ili bwino komanso yosasinthidwa. Algorithm ya MD5 sichinsinsi. Chidindo chokha cha zomwe mwapatsidwa. Komabe, iyi ndi njira imodzi yokha ndipo chifukwa chake ndizosatheka kutembenuza mainjiniya ma algorithm a MD5 kuti mupeze chingwe choyambirira.

Kodi MD5 checksum imawerengedwa bwanji?

Ngati mukudziwa cheke cha fayilo yoyambirira ndipo mukufuna kuyang'ana pa kompyuta yanu, mutha kuchita izi mosavuta. M'mitundu yonse ya Windows, macOS, ndi Linux, mutha kugwiritsa ntchito zida zomangira kuti mupange macheke. Palibe chifukwa choyika zida zina zilizonse.

Pa Windows, lamulo la PowerShell Get-FileHash limawerengera cheke cha fayilo. Kuti mugwiritse ntchito, choyamba tsegulani PowerShell. Kuti muchite izi, mu Windows 10, dinani kumanja pa batani loyambira ndikusankha "Windows PowerShell". Lembani njira ya fayilo yomwe mukufuna kuwerengera mtengo wa checksum. Kapena, kuti zinthu zikhale zosavuta, kokerani ndikugwetsa fayilo kuchokera pawindo la File Explorer pawindo la PowerShell kuti mudzaze njira ya fayilo. Dinani Enter kuti muthamangitse lamulolo ndipo muwona SHA-256 hash ya fayilo. Kutengera kukula kwa fayilo komanso liwiro la kusungirako kompyuta yanu, njirayi ingatenge masekondi angapo. Ngati checksum ikufanana, mafayilo ali ofanana. Ngati sichoncho, pali vuto. Pankhaniyi, mwina fayiloyo ndi yachinyengo kapena mukufanizira mafayilo awiri osiyana.
