Fayilo ya hash kapena checksum ndi yochepa yapadera yowerengedwa kuchokera pa mafayilo omwe ali nawo ndipo kawirikawiri amagwiritsidwa ntchito kuti ayang'ane umphumphu ndi kusagwirizana (machesi) a mafayilo pakutha, makamaka ponena za mafayilo akuluakulu (mafano a machitidwe ndi zina zotero) zomwe zingathe kumasulidwa ndi zolakwika kapena pali kukayikira kuti fayilo yatsatiridwa ndi maluso.
Malo otsatsa nthawi zambiri amakhala ndi checksum yowerengeka pogwiritsa ntchito MD5, SHA256 ndi zina zowonjezereka, kukulolani kutsimikizira fayilo lololedwa ndi fayilo yomwe imayikidwa ndi womanga. Mapulogalamu apamwamba angagwiritsidwe ntchito powerenga checksums ya mafayilo, koma pali njira yochitira izi pogwiritsira ntchito zida zowonjezera Windows 10, 8 ndi Windows 7 (zimafuna PowerShell 4.0 kapena apamwamba) - pogwiritsira ntchito PowerShell kapena mzere wa lamulo, womwe udzawonetsedwa m'mawu ake.
Kupeza checksum ya fayilo pogwiritsa ntchito Mawindo
Choyamba muyenera kuyamba Windows PowerShell: njira yophweka ndiyo kugwiritsa ntchito kufufuza mu barabu a Windows 10 kapena Windows 7 Yambani mndandanda wa izi.
Lamulo lowerengera laha la fayilo ku PowerShell - Pezani-filehash, ndikugwiritsa ntchito kuti muwerenge checksum, ndikwanira kuti mulowemo ndi magawo otsatirawa (mwachitsanzo, hayi yawerengedwa kwa ISO chithunzi cha Windows 10 kuchokera ku fayilo ya VM pa galimoto C):
Pezani FichiHash C: VM Win10_1607_Russian_x64.iso | Mndandanda wa Mndandanda
Pogwiritsira ntchito lamulo mu mawonekedwe awa, hayi imawerengedwa pogwiritsa ntchito SHA256 ndondomeko, koma zina zothandizira zimathandizidwa, zomwe zingagwiritsidwe ntchito -Algorithm parameter, mwachitsanzo, kuwerengera MD5 checksum, lamulo lidzawoneka ngati chitsanzo chomwe chili pansipa
Pezani Faili C: VM Win10_1607_Russian_x64.iso -Algorithm MD5 | Mndandanda wa Mndandanda
Zotsatira zotsatirazi zimathandizidwa pa zowonongeka zowonongeka mu Windows PowerShell
- SHA256 (zosasintha)
- MD5
- SHA1
- SHA384
- SHA512
- MACTripleDES
- RIPEMD160
Mndandanda wa tsatanetsatane wa mawu omveka a lamulo la Get-FileHash umapezeka pa webusaitiyi //technet.microsoft.com/en-us/library/dn520872(v=wps.650).aspx
Kupeza fayilo payeyumu ya malamulo ndi CertUtil
Pa Windows, muli CertUtil yokhazikika yogwiritsira ntchito zizindikiro, zomwe, mwa zina, zingathe kuwerengetsa checksum ya mafayilo pogwiritsa ntchito machitidwe:
- MD2, MD4, MD5
- SHA1, SHA256, SHA384, SHA512
Kuti mugwiritse ntchito, mungothamanga mzere wa mawindo a Windows 10, 8 kapena Windows 7 ndi kuika lamulo mu fomu ili:
certutil -hashfile path_to_file algorithm
Chitsanzo chotsitsira MD5 hash kwa fayilo ikuwonetsedwa mu skrini pansipa.
Zowonjezereka: ngati mukusowa mapulogalamu apakati pazomwe mukuwerengera mafayilo mu Windows, mukhoza kumvetsera SlavaSoft HashCalc.
Ngati mukufuna kuwerenga checksum mu Windows XP kapena mu Windows 7 popanda PowerShell 4 (ndikutha kuikha), mungagwiritse ntchito mauthenga amtundu wa malamulo a Microsoft File Checksum Integrity Verifier omwe angathe kupezeka pa webusaitiyi //www.microsoft.com/en -us / download / details.aspx? id = 11533 (mawonekedwe a lamulo kuti agwiritse ntchito: fciv.exe file_path - Zotsatira zidzakhala MD5. Mukhozanso kuwerengetsa SHA1 hasi: fciv.exe -sha1 path_to_file)
