Imizekelo yeTycksum, Sebenzisa iimeko, kunye ne-Calculators
I-checksum yiphumo lokusebenzisa i-algorithm, ebizwa ngokuthi umsebenzi we- cryptographic hash , kwinqanaba leenkcukacha, ngokuqhelekileyo ifayile enye. Ukuthelekisa i-checksum oyenzayo ukusuka kwinguqulo yakho yefayili, kunye nomnye onikezelwe ngumthombo wefayili, inceda ukuqinisekisa ukuba ikopi yakho yefayili yinyani kunye nephutha.
I-checksum ikwabizwa ngamanye amaxesha isisithsi se- hash kwaye kaninzi iphinda ixabiso le- hash, ikhowudi ye-hash okanye i- hash nje .
Umzekelo woLuhlu olulula
Ingcamango yechungechunge okanye umsebenzi we-cryptographic hash ibonakala ngathi iyinkimbinkimbi kwaye ayinakukufanelekela umzamo, kodwa sifuna ukukuqinisekisa! Iicandelo lee-checksums azikho nzima ukuqonda okanye ukudala.
Masiqale ngomzekelo olula, sinethemba lokubonisa amandla amakhredithi ukubonisa ukuba into ishintshile. I-checksum ye-MD5 yale binzana ibinombambo omude wabalinganiswa abamele eso sigwebo.
Olu luvavanyo. 120EA8A25E5D487BF68B5F7096440019Ngeenjongo zethu apha, ngokulinganayo zilingana. Nangona kunjalo, yenza utshintsho oluncinane, njengokususa ixesha elifanelekileyo, liya kuvelisa i-checksum ehlukileyo ngokupheleleyo:
Olu luvavanyo CE114E4501D2F4E2DCEA3E17B546F339Njengoko ubona, nokuba utshintsho oluncinci kwifayili luza kuvelisa i-checksum ehlukileyo, okwenza kucace ukuba umntu akafani nomnye.
I-Checksum Sebenzisa I-Case
Makhe ukukhuphela ukuhlaziywa okukhulu, njengepakethi yesevisi , kwiprogram oyisebenzisayo imihla ngemihla, njengomhleli wemifanekiso. Oku mhlawumbi ifayile enkulu, ithatha imizuzu emininzi okanye ngaphezulu ukukhuphela.
Emva kokukhutshelwa, uyayazi njani ukuba ifayile ilandwe ngokufanelekileyo? Kuthekani ukuba iimbalwa ezimbalwa zahlaselwa ngexesha lokukhuphela kunye nefayili onayo kwiikhomputha yakho ngoku ayikho into ekujoliswe kuyo? Ukusebenzisa ukuhlaziywa kwiprogram engekona indlela umthuthukisi oyidalile ngayo ekunokubangela iingxaki ezinkulu.
Yilapho ukuthelekisa iitshekishekisi kunokubeka ingqondo yakho lula. Ukucinga ukuba i-website uyikhuphele ifayile ukusuka ekunikezeni idatha ye-checksum kunye nefayili ekufuneka ilandwe, ungasebenzisa i-checksum calculator (bona i- Checksum Calculators engezansi ) ukuvelisa i-checksum kwifayili yakho ekhutshwe.
Ngokomzekelo, yithi lewebhu inikezela i-checksum MD5: 5a828ca5302b19ae8c7a66149f3e1e98 kwifayile oyilandileyo . Emva koko usebenzisa i-checksum yakho yokubala i-checksum ukuvelisa i-checksum usebenzisa umsebenzi ofanayo we-cryptographic hash, i-MD5 kule mzekelo, kwifayile kwikhompyuter yakho. Ngaba iitshekishegi ziyafana? Kakhulu! Unokuqiniseka ukuba ezi fayile zifana.
Ngaba iitshekethi azifani? Oku kunokuthetha nantoni na into yokuba umntu uthathe indawo yokukhuphela kunye nento enobungozi ngaphandle kokuba uyazi, ngenxa yesono esincinane njengokuba uvula kwaye utshintshe ifayile, okanye uxhumano lwenethiwekhi luphazamisekile kwaye ifayile ayizange iqede ukukhuphela. Zama ukulanda ifayile kwakhona uze wenze i-checksum entsha kwifayili entsha uze uqhathele kwakhona.
Iifowuni nazo zinceda ekuqinisekiseni ukuba ifayile oyilandileyo ukusuka kwenye indawo ngaphandle kwendalo yokuqala, eqinisweni, ifayile echanekileyo kwaye ayitshintshiwe, ngokungafanelekanga okanye ngenye indlela, evela kwimoqobo. Qhathanisa i-hash oyidalayo kunye nekhoyo evela kumthombo wefayili.
Checksum Calculators
I-Checksum calculators zixhobo ezisetyenziselwa ukulinganisa iitshekisi. Kukho ezininzi zokuhlola i-checksum apho, nganye isekela isethi eyahlukileyo yemisebenzi ye-hasptographic hash.
Enye ye-free checksum calculator yi-Microsoft File Checksum Integrity Verifier, ebizwa ngokuba yi- fciv efutshane. I-Fciv isekela kuphela imisebenzi ye- MD5 ne- SHA-1 ye- heptographic hash kodwa yona yinto eyaziwayo kakhulu ngoku.
Jonga indlela yokuqinisekisa ubungqina beFayile kwi-Windows kunye ne-FCIV ye-tutorial epheleleyo. I-Microsoft File Checksum Integrity Verifier yinkqubo yomyalelo-myalelo kodwa kulula ukuyisebenzisa.
Enye i-checksum yokubala yamahhala ye-Windows i-Hasor ye-IgorWare, kwaye iphathekayo ngokupheleleyo kwaye akudingeki ukuba ufake enye into. Ukuba awuhlali ukhululekile kunye nezixhobo zomgca-myalelo, le nkqubo mhlawumbi iyona nto ingcono. Ixhasa i-MD5 kunye neSHA-1, kunye ne-CRC32. Ungasebenzisa iHasWare Hasher ukufumana i-checksum yombhalo kunye neefayile.
I-JDigest ngumthombo wokuhlola ovulekileyo osebenza kwiWindows kunye nakwi-macOS kunye ne-Linux.
Qaphela: kuba kungekhona yonke i-checksum calculators inkxaso yonke imisebenzi ye-hasptographic hash, qiniseka ukuba nayiphi i-checksum calculator oyisebenzisayo isekela umsebenzi we-hash ovelise i-checksum ehamba nefayili oyilanda.
