Tonse timakonda kutumiza deta pa intaneti kapena maukonde ena am'deralo. Nthawi zambiri, deta yotere imasamutsidwa pa intaneti ngati ma bits. Nthawi zambiri, matani a data akatumizidwa pa netiweki, amatha kutayika chifukwa cha vuto la netiweki kapena kuwukira koyipa. Checksum imagwiritsidwa ntchito kuwonetsetsa kuti zomwe zalandilidwa sizikuvulazidwa komanso zopanda zolakwika ndi zotayika. Checksum imagwira ntchito ngati chala kapena chizindikiritso chapadera cha data.
Kuti mumvetse bwino izi, ganizirani izi: Ndikukutumizirani dengu la maapulo kudzera mwa woperekera katundu. Tsopano, popeza wothandizira ndi gulu lachitatu, sitingathe kudalira kutsimikizika kwake kwathunthu. Chotero kuti nditsimikizire kuti sanadye maapulo ali m’njira ndi kuti mulandire maapulo onse, ndikukuitanani ndikukuuzani kuti ndakutumizirani maapulo 20. Mukalandira dengu, mumawerengera maapulo ndikuwona ngati ndi 20.
Kuwerengera kwa maapulo ndizomwe checksum imachita pafayilo yanu. Ngati mwatumiza fayilo yayikulu kwambiri pa netiweki (chipani chachitatu) kapena mwatsitsa kuchokera pa intaneti ndipo mukufuna kuonetsetsa kuti fayiloyo yatumizidwa kapena kulandilidwa bwino, mumagwiritsa ntchito algorithm ya chequesum pafayilo yanu yomwe ikugwiritsidwa ntchito. anatumiza ndi kufotokoza mtengo kwa wolandira. Mukalandira fayilo, wolandila adzagwiritsa ntchito algorithm yomweyi ndikufananiza mtengo womwe mwapeza ndi zomwe mwatumiza. Ngati zikhalidwe zikugwirizana, fayilo yatumizidwa molondola ndipo palibe deta yomwe yatayika. Koma ngati zikhalidwe zili zosiyana, wolandirayo adzadziwa nthawi yomweyo kuti deta ina yatayika kapena fayilo yasokonezedwa pa intaneti. Popeza deta ikhoza kukhala yovuta kwambiri komanso yofunikira kwa ife, ndikofunikira kuyang'ana cholakwika chilichonse chomwe chingakhale chinachitika potumiza. Chifukwa chake, cheke ndi yofunika kwambiri kuti musunge zowona komanso kukhulupirika kwa data. Ngakhale kusintha kochepa kwambiri kwa deta kumayambitsa kusintha kwakukulu mu checksum. Ma protocol monga TCP/IP omwe amalamulira malamulo olankhulirana pa intaneti amagwiritsanso ntchito cheke kuti atsimikizire kuti nthawi zonse zolondola zimaperekedwa.
Checksum kwenikweni ndi algorithm yomwe imagwiritsa ntchito cryptographic hash. Algorithm iyi imagwiritsidwa ntchito pachidutswa cha data kapena fayilo musanatumize komanso mutayilandira pamaneti. Mutha kuwona kuti imaperekedwa pambali pa ulalo wotsitsa kuti mukatsitsa fayiloyo, mutha kuwerengera cheke pakompyuta yanu ndikuyifananiza ndi mtengo womwe mwapatsidwa. Dziwani kuti kutalika kwa checksum sikudalira kukula kwa deta koma pa algorithm yogwiritsidwa ntchito. Ma algorithms omwe amagwiritsidwa ntchito kwambiri ndi MD5 (Message Digest algorithm 5), SHA1 (Secure Hashing Algorithm 1), SHA-256 ndi SHA-512. Ma algorithms awa amapanga 128-bit, 160-bit, 256 -bit ndi 512-bit hashi motsatana. SHA-256 ndi SHA-512 ndi zaposachedwa kwambiri komanso zamphamvu kuposa SHA-1 ndi MD5, zomwe nthawi zina zimatulutsa macheke omwewo pamafayilo awiri osiyanasiyana. Izi zinasokoneza kutsimikizika kwa ma aligorivimu amenewo. Njira zatsopano ndi umboni wolakwika komanso wodalirika. Ma aligorivimu a Hashing amasintha zambiri kuti zikhale zofanana ndi zomwe zili mu binary kenako ndikuchita zina zofunika monga AND, OR, XOR, ndi zina zotero.

Checksum ndi chiyani? Ndipo Momwe Mungawerengere Ma Checksum
Njira 1: Kuwerengera Checksums pogwiritsa ntchito PowerShell
1.Gwiritsani ntchito kusaka koyambira pa Windows 10 ndikulemba PowerShell ndipo dinani ' Windows PowerShell ' kuchokera pamndandanda.
2.Alternatively, mutha dinani pomwepa poyambira ndikusankha ' Windows PowerShell ' kuchokera ku menyu.
3.Mu Windows PowerShell, yendetsani lamulo ili:
|_+_|4.Chidziwitso chidzawonetsedwa Mtengo wa SHA-256 mwachisawawa.
5.Pa ma aligorivimu ena, mutha kugwiritsa ntchito:
|_+_|Tsopano mutha kufananiza mtengo womwe mwapeza ndi mtengo womwe mwapatsidwa.
Njira 2: Werengetsani Checksum pogwiritsa ntchito Online Checksum Calculator
Pali zowerengera zambiri zapaintaneti ngati 'onlinemd5.com'. Tsambali litha kugwiritsidwa ntchito kuwerengera macheke a MD5, SHA1 ndi SHA-256 pafayilo iliyonse ngakhale palemba lililonse.
1. Dinani pa ' Sankhani wapamwamba ' batani ndikutsegula fayilo yomwe mukufuna.
2.Alternatively, kuukoka ndi kusiya wapamwamba wanu anapatsidwa bokosi.
3.Sankhani yanu algorithm yomwe mukufuna ndikupeza cheke chofunikira.
