Checksum Piv txwv, Siv Cov Ntaub Ntawv, thiab Cov Tshuab
Ib qho kev checksum yog qhov tshwm sim ntawm khiav ib qho algorithm, hu ua cryptographic hash muaj nuj nqi , nyob rau ib daim ntawm cov ntaub ntawv, feem ntau yog ib cov ntaub ntawv . Sib piv cov checksum uas koj tsim los ntawm koj cov ntaub ntawv ntawm cov ntaub ntawv, nrog rau ib qho los ntawm qhov chaw ntawm cov ntaub ntawv, pab xyuas kom koj daim ntawv luam ntawm cov ntaub ntawv yog qhov tseeb thiab yuam kev dawb.
Ib qho kev checksum kuj qee zaum hu ua hash sum thiab tsawg dua ib qho nuj nqis ntawm hash , hash code , los yog tsuas yog ib tug hash .
Ib qho piv txwv Checksum yooj yim
Lub tswv yim ntawm kev checksum los yog ib qho kev ua hauj lwm cryptographic hash yuav zoo li nyuab thiab tsis tau tsim nyog rau kev siv zog, tab sis peb xav convince koj txwv tsis pub! Checksums yeej tsis yog qhov nyuaj to taub los yog tsim tau.
Cia peb pib nrog ib tug piv txwv yooj yim, vam tias pom tau tias lub zog ntawm checksums los ua pov thawj tias ib yam dab tsi tau hloov. Lub MD5 checksum rau kab lus nram qab no yog ib txoj hlua ntev ntawm cov cim uas sawv cev rau kab ntawv ntawd.
Qhov no yog kev sim. 120EA8A25E5D487BF68B5F7096440019Rau peb lub hom phiaj ntawm no, lawv yeej tseem zoo sib npaug. Txawm li cas los xij, ua ib qho kev hloov me ntsis, zoo li tshem tawm tsuas yog lub sij hawm, yuav tsim cov checksum sib txawv kiag li:
Qhov no yog ib qho kev xeem CE114E4501D2F4E2DCEA3E17B546F339Raws li koj tau pom, txawm tias tus minuscule hloov nyob rau hauv cov ntaub ntawv yuav tsim ib qho sib txawv checksum vastly, ua nws heev tias ib tug tsis zoo li lwm.
Checksum Siv Case
Peb hais tias koj download tau ib qho kev hloov tshiab, zoo li ib qhov kev pabcuam , mus rau ib qho kev pabcuam koj siv txhua hnub, zoo li cov duab editor. Qhov no yog zaum ua ntaub ntawv loj heev, kev siv ob peb feeb los yog ntau dua mus download tau.
Thaum twg downloaded, ua li cas koj paub tias cov ntaub ntawv downloaded zoo? Yuav ua li cas yog tias ob peb qho khoom poob thaum lub download thiab cov ntaub ntawv koj muaj nyob rau hauv koj lub computer tam sim no tsis yog raws nraim li cas npaj? Thov kev hloov tshiab rau qhov kev zov me nyuam uas tsis yog raws nraim li tus tsim tawm tsim nws yog qhov yuav ua rau koj muaj teeb meem loj.
Qhov no yog qhov sib piv checksums tuaj yeem ua rau koj lub siab nyob ntawm yooj yim. Yog tias lub website koj downloaded cov ntaub ntawv los ntawm kev muab cov ntaub ntawv checksum nrog rau hauv cov ntaub ntawv yuav tsum downloaded, koj tuaj yeem siv cov checksum calculator (saib Checksum Calculators hauv qab) los tsim ib checksum los ntawm koj cov ntaub ntawv downloaded.
Piv txwv, hais lub website muaj tus checksum MD5: 5a828ca5302b19ae8c7a66149f3e1e98 rau cov ntaub ntawv koj downloaded. Koj mam li siv koj tus checksum lub laij lej los tsim cov checksum uas siv tib qhov kev ua haujlwm cryptographic hash, MD5 nyob rau hauv qhov ua piv txwv, rau hauv cov ntaub ntawv ntawm koj lub computer. Ua tus checksums match? Yawm suab! Koj tuaj yeem ntseeg siab tias ob daim ntawv sib txawv.
Ua cov checksums tsis phim? Qhov no txhais tau tias txhua yam ntawm qhov tseeb hais tias ib tug neeg tau hloov lub download nrog tej yam siab phem tsis muaj koj paub txog, vim li cas ho tsis txaus ntshai li ntawd koj qhib thiab hloov cov ntaub ntawv, lossis kev sib txuas ntawm lub network tau ncua thiab cov ntaub ntawv tsis tas thaij. Sim downloading cov ntaub ntawv dua thiab mam li tsim ib qho tshiab checksum rau ntawm cov ntaub ntawv tshiab thiab piv dua.
Checksums yog ib qho tseem ceeb rau kev tshawb xyuas tias cov ntaub ntawv koj downloaded ntawm qhov chaw uas tsis yog thawj qhov chaw, qhov tseeb, siv tau cov ntaub ntawv thiab tsis tau hloov, maliciously los yog lwm yam, los ntawm tus thawj. Cia li sib txawv ntawm qhov hash koj tsim nrog rau ib qho muaj los ntawm cov ntaub ntawv qhov chaw.
Checksum Tshuab xam zauv
Checksum calculators yog cov cuab yeej siv los txheeb cov checksums. Muaj ntau cov checksum calculators tawm muaj, txhua tus txhawb ntau txheej cryptographic hash functions.
Ib qho great dawb checksum tswvyim yog Microsoft Ntaub Ntawv Checksum Integrity Verifier, hu ua fciv luv luv. Fciv txhawb cov MD5 thiab SHA-1 cryptographic hash functions tab sis cov no yog nyob deb tshaj plaws tam sim no.
Saib Xyuas Yuav Ua Li Cas thiaj Txheeb Xyuas Daim Ntawv Nplij Nyug Rau Hauv Qhov Ncauj nrog FCIV rau kev nyeem tiav. Microsoft File Checksum Integrity Verifier yog ib qhov kev pab cuam kab- kev siv, tiam sis nws yooj yim heev rau siv.
Ib qho zoo tshaj plaws dawb checksum tswvyim rau lub qhov rais yog IgorWare Hasher, thiab nws yog li portable li koj tsis muaj rau nruab dab tsi. Yog tias koj tsis nyiam nrog cov cuab yeej siv kab-kev, qhov kev qhia no yog qhov kev xaiv zoo dua. Nws txhawb MD5 thiab SHA-1, zoo li CRC32. Koj siv tau IgorWare Hasher los nrhiav cov checksum ntawm cov ntawv nyeem thiab cov ntaub ntawv.
JDigest yog qhib checksum tshuab xam zauv uas ua hauj lwm hauv Windows, thiab MacOS thiab Linux.
Ceebtoom: Vim tsis yog txhua tus checksum calculators txhawb txhua qhov kev ua haujlwm tau cryptographic, nco ntsoov tias txhua tus checksum calculator koj xaiv los pab txhawb qhov kev ua haujlwm uas tau ua tus checksum uas nrog cov ntaub ntawv koj downloading.
