Peb txhua tus tau siv los xa cov ntaub ntawv hauv Is Taws Nem lossis lwm lub network hauv zos. Feem ntau, cov ntaub ntawv zoo li no raug xa mus rau hauv lub network hauv daim ntawv ntawm cov khoom. Feem ntau, thaum tons ntawm cov ntaub ntawv raug xa mus rau hauv lub network, nws yog qhov raug rau cov ntaub ntawv poob vim muaj teeb meem network lossis txawm tias muaj kev tawm tsam phem. Lub checksum yog siv los xyuas kom meej tias cov ntaub ntawv tau txais tsis raug mob thiab tsis muaj kev ua yuam kev thiab poob. Checksum ua tus ntiv tes lossis tus cim tshwj xeeb rau cov ntaub ntawv.
Txhawm rau nkag siab qhov no zoo dua, xav txog qhov no: Kuv xa koj lub pob tawb ntawm txiv apples ntawm qee tus neeg xa khoom. Tam sim no, txij li tus neeg sawv cev xa khoom yog tus thib peb, peb tsis tuaj yeem tso siab rau nws qhov tseeb nkaus. Yog li ntawd kom nws tsis txhob noj txiv apples ntawm nws txoj kev thiab tias koj tau txais tag nrho cov txiv apples, kuv hu koj thiab qhia rau koj tias kuv tau xa koj 20 apples. Thaum tau txais lub pob tawb, koj suav cov txiv apples thiab xyuas seb nws puas yog 20.
Qhov suav ntawm txiv apples yog qhov checksum ua rau koj cov ntaub ntawv. Yog tias koj tau xa cov ntaub ntawv loj heev hauv lub network (thib neeg thib peb) lossis koj tau rub tawm ib qho los ntawm Is Taws Nem thiab koj xav kom paub tseeb tias cov ntaub ntawv tau raug xa los yog tau txais lawm, koj siv lub checksum algorithm ntawm koj cov ntaub ntawv uas tab tom ua. xa thiab sib txuas lus tus nqi rau tus txais. Thaum tau txais cov ntaub ntawv, tus txais yuav siv tib lub algorithm thiab phim tus nqi tau nrog qhov koj tau xa. Yog tias tus nqi sib tw, cov ntaub ntawv tau raug xa mus kom raug thiab tsis muaj ntaub ntawv ploj lawm. Tab sis yog tias tus nqi sib txawv, tus txais yuav tam sim paub tias qee cov ntaub ntawv tau ploj lawm lossis cov ntaub ntawv tau raug cuam tshuam nrog hauv lub network. Txij li thaum cov ntaub ntawv tej zaum yuav rhiab heev thiab tseem ceeb rau peb, nws yog ib qho tseem ceeb uas yuav tau xyuas tej yam yuam kev uas yuav tshwm sim thaum kis tau tus mob. Yog li, ib qho checksum tseem ceeb heev los tswj cov ntaub ntawv tseeb thiab kev ncaj ncees. Txawm tias qhov kev hloov me me ntawm cov ntaub ntawv ua rau muaj kev hloov pauv loj hauv daim tshev nyiaj. Cov txheej txheem zoo li TCP / IP uas tswj hwm txoj cai sib txuas lus hauv internet kuj tseem siv cov checksum kom paub tseeb tias cov ntaub ntawv raug xa mus tas li.
Lub checksum yog ib qho algorithm uas siv cryptographic hash muaj nuj nqi. Qhov algorithm no yog siv los ntawm ib daim ntawm cov ntaub ntawv lossis cov ntaub ntawv ua ntej xa thiab tom qab tau txais nws hauv lub network. Tej zaum koj yuav tau pom tias nws tau muab ib sab ntawm qhov txuas rub tawm kom thaum koj rub tawm cov ntaub ntawv, koj tuaj yeem suav cov checksum ntawm koj tus kheej lub computer thiab phim nws nrog tus nqi muab. Nco ntsoov tias qhov ntev ntawm daim tshev nyiaj tsis nyob ntawm qhov loj ntawm cov ntaub ntawv tab sis ntawm cov algorithm siv. Feem ntau cov checksum algorithms siv yog MD5 (Message Digest algorithm 5), SHA1 (Secure Hashing Algorithm 1), SHA-256 thiab SHA-512. Cov algorithms no tsim 128-ntsis, 160-ntsis, 256-ntsis thiab 512-ntsis hash qhov tseem ceeb. SHA-256 thiab SHA-512 yog qhov tsis ntev los no thiab muaj zog dua SHA-1 thiab MD5, uas nyob rau qee qhov tsis tshua muaj tsim cov txiaj ntsig zoo tib yam rau ob cov ntaub ntawv sib txawv. Qhov no compromised lub validity ntawm cov algorithms. Cov txheej txheem tshiab yog cov pov thawj yuam kev thiab txhim khu kev qha. Hashing algorithm tsuas yog hloov cov ntaub ntawv mus rau nws qhov sib npaug binary thiab tom qab ntawd nqa qee qhov haujlwm yooj yim xws li THIAB, LOSSIS, XOR, thiab lwm yam ntawm nws thiab thaum kawg rho tawm tus nqi hex ntawm kev suav.

Checksum yog dab tsi? Thiab Yuav Ua Li Cas Sau Cov Ntawv Pov Thawj
Txoj Kev 1: xam Checksums siv PowerShell
1.Siv cov kev tshawb fawb ntawm pib cov ntawv qhia zaub mov ntawm Windows 10 thiab ntaus PowerShell thiab nias rau ' Windows PowerShell ' ntawm lis.
2.Xwb, koj tuaj yeem nyem rau ntawm qhov pib thiab xaiv ' Windows PowerShell ' los ntawm cov ntawv qhia zaub mov.
3.In Windows PowerShell, khiav cov lus txib hauv qab no:
|_+_|4.Cov lus ceeb toom yuav tso tawm SHA-256 hash tus nqi los ntawm lub neej ntawd.
5.Rau lwm cov algorithms, koj tuaj yeem siv:
|_+_|Tam sim no koj tuaj yeem phim tus nqi tau nrog tus nqi muab.
