Cov ntaub ntawv hash lossis checksum yog luv nqi txawv ntawm cov ntaub ntawv thiab feem ntau yog siv los xyuas qhov ncaj ncees thiab kev sib nkag siab ntawm cov ntaub ntawv thaum lub sij hawm download, tshwj xeeb tshaj yog thaum nws los txog rau cov ntaub ntawv loj (system dluab thiab cov zoo li) uas tuaj yeem raug xa tawm nrog cov muaj ntau lub sijhawm uas cov ntaub ntawv tau hloov los ntawm malware.
Download tau qhov chaw feem ntau muaj kev checksum siv MD5, SHA256 thiab lwm yam algorithms, uas koj mus xyuas cov ntaub ntawv downloaded nrog cov ntaub ntawv uploaded ntawm tus tsim tawm. Cov kev pabcuam thib peb tuaj yeem siv los xyuas cov checksums ntawm cov ntaub ntawv, tab sis nws muaj ib txoj hauv kev los ua qhov kev siv qhov rai 10, 8 thiab Windows 7 (yuav tsum PowerShell 4.0 lossis siab dua) - siv PowerShell lossis kab lus, uas yuav qhia tawm hauv cov lus qhia.
Tau txais cov checksum ntawm cov ntaub ntawv siv lub qhov rais
Ua ntej koj yuav tsum pib PowerShell qhov rais: qhov yooj yim tshaj yog siv qhov kev tshawb fawb hauv lub khoos phis tawj 10 lossis Windows 7 Start zaub mov rau qhov no.
Lo lus txib los laij cov hash rau ib daim ntawv hauv PowerShell - Tau-ntawvhash, thiab siv nws los laij cov checksum, nws txaus rau nws nkag mus nrog cov lus hauv qab no (hauv qhov piv txwv, tus hash yog xam rau daim duab ISO ntawm 10 lub VM nplaub tshev ntawm C):
Tau-FileHash C: VM Win10_1607_Russian_x64.iso | Hom Ntawv-Sau
Thaum siv cov lus txib hauv daim ntawv no, lub hash yog xam siv SHA256 algorithm, tab sis lwm cov kev xaiv yog txhawb, uas yuav tau teem siv lub -Algorithm parameter, piv txwv li, los xam MD5 checksum, qhov hais kom ua yuav zoo li hauv qhov piv txwv hauv qab
Tau-FileHash C: VM Win10_1607_Russian_x64.iso -Algorithm MD5 | Hom Ntawv-Sau
Cov nram qab no qhov tseem ceeb yog kev txhawb rau kev checksum xam kev algorithms nyob rau hauv Windows PowerShell
- SHA256 (vim)
- MD5
- SHA1
- SHA384
- SHA512
- MACTRipleDES
- RIPEMD160
Ib cov ncauj lus qhia tseeb ntawm cov syntax rau cov lus hais ntawm Get-FileHash kuj muaj nyob rau hauv lub website ntawm //technet.microsoft.com/en-us/library/dn520872(v=wps.650).aspx
Tau txais ib daim ntawv hash ntawm qhov hais kom ua kab nrog CertUtil
Rau ntawm Qhov rai, yog ib qho chaw ua haujlwm hauv CertUtil rau kev ua hauj lwm nrog cov ntawv pov thawj, uas, ntawm lwm yam, muaj peev xwm xam cov checksum ntawm cov ntaub ntawv siv algorithms:
- MD2, MD4, MD5
- SHA1, SHA256, SHA384, SHA512
Siv lub fais fab, cia li khiav ntawm Windows 10, 8 los yog Windows 7 hais kom ua kab thiab nkag mus rau kev hais kom ua raws li cov hauv qab no:
certutil -hashfile path_to_file algorithm
Ib qho piv txwv ntawm kev tau txais ib qho MD5 hash rau ib daim ntawv qhia muaj nyob rau hauv lub screenshot hauv qab no.
Ntxiv: nyob rau hauv cov ntaub ntawv koj xav tau cov kev pabcuam thib peb rau xam xyuas cov ntawv sau hauv qhov rais, koj tuaj yeem mloog Payment rau SlavaSoft HashCalc.
Yog tias koj xav los xam cov checksum hauv Windows XP lossis hauv Windows 7 tsis muaj PowerShell 4 (thiab lub peev xwm los nruab nws), koj siv tau Microsoft Ntaub Ntawv Checksum Integrity Verifier hais kom ua hluav taws xob muaj nyob rau hauv lub website www.microsoft.com/en -us / download / details.aspx? id = 11533 (hom ntawm cov lus txib kom siv lub fais fab: fciv.exe file_path - Qhov tshwm sim yuav yog MD5. Koj tuaj yeem xam tau cov SHA1 hash: fciv.exe -sha1 path_to_file)
