Ukukhangela izibalo hashe: ntoni na?

kubasebenzisi abaninzi computer ekuhambeni kwexesha, xa kwabazana kufutshane, ibuza malunga hashe-izibalo. Zibizwa ngokuba checksum. Yintoni na? Into oyifunayo? Indlela kubalwa ezi zixa-mali efanayo?

definition

Checksum kuthiwa ixabiso elithile, ebalwayo idatha esebenzisa ubuchule ezizodwa. izibalo hashi Injongo - ekuhloleni ingqibelelo data ngexesha yokosulela. Ubuchule zixhaphakileyo ukubala - MD5, CRC32 kunye SHA-1. Checksums inokusetyenziswa ukuthelekisa iiseti data kwi non-ukulingana, njengokuba kufanelekile, ngokuba ekufumanekeni iintsholongwane kwikhompyutha yakho.

Ukuthandwa ukusetyenziswa kwale ndlela kuvela kwinyaniso yokuba uvavanyo kulula ukuba uziphumeze izixhobo yedijithali, ukusebenza kunye binary inkqubo yokubala. It ihlaziya ngaphandle ingxaki kwaye olukhulu ekufumaneni iimpazamo ukuba zibangelwa yi ubukho ingxolo emendweni data.

Ubuchule sokuhlola

I algorithm MD5 ke kuphela kusetyenziswa ukuqinisekisa ukuthembeka kwedatha, kodwa inika ithuba lokuba bafumane into ebonakalisayo ngokwanelisayo ethembekileyo, leyo isoloko isetyenziswa kwimeko apho efanayo afumaneka kwi iifayili kwikhompyutha. Ngoko ke, akukho luthelekiso imixholo, kunye nezibalo lwabo hashe.

CRC32 algorithm kusetyenziswa kwiinkqubo kumphati. Imela njenge "ikhowudi komsebenzi elibujikele".

SHA-1 algorithm ifumene isicelo ukuqinisekiswa engqibelelweni data, ezo zilayishwe ngokusebenzisa inkqubo BitTorrent.

umzekelo

Ngokomzekelo, omnye umsebenzisi ufuna ukufaka inkqubo okanye umdlalo yokusebenza kwi-PC yakho. It quality umfanekiso kwaye ufuna ukuqinisekisa ukuba isidima ifayile ukuze kwaye nto transfer ilahlekileyo. Indlela elula yokwenza oku - ukuthelekisa a asa le fayile ukulandwa, kwaye iimali ezinikezelwa ngumbhali. Ukuba ngaxeshanye, umfanekiso ayiqulathanga iimpazamo. Kaloku, ukuba asa sum of iifayile ezahlukeneyo, kuyimfuneko ukuba yokumpompa kwakhona, ngenxa yokuba kwakukho ukusilela.

Le nkqubo iyevakala ngumlinganiselo othintelo nxamnye umsebenzi engachanekanga kubambelela. Running kuyo, unokuqiniseka ukuba ukufakelwa kwenkqubo esebenzayo, iinkqubo okanye imidlalo ziya kuba zezichanekileyo.

Ezi zinto zilandelayo ziya ukuchaza into eluncedo, uhlangabezana njani nale ukubala kunye nokuqinisekisa checksums.

Inkqubo HashTab khangela asa sum

Le nkampani i plugin ihlanganise kwinkqubo yokusebenza kwaye lisetyenziswa kumaxesha anzima. It zingakotshwa ngekhompyutha kweli ziko lewebhu esemthethweni ngokupheleleyo ngaphandle kwentlawulo ngohlobo kwifayile ufakelo. Ukufakela inkqubo ibonakala kakhulu.

Emva ukubeka iimpawu ifayile nganye iya kunika i tab esitsha ezongezelelweyo yokubala checksum. Ngokungagqibekanga, ziya kubalwa kwi ubuchule ezininzi zintathu zicaciswe apha ngentla.

Indlela ukukhangela asa mali? Ukwenza oku kwi "Thelekisa 'endle ukufaka isixa eboniswe ngumbhali. Ukuba ifayile elayishelwe ezantsi ivavanywe ukunyaniseka, a maki eluhlaza ngempumelelo. Kungenjalo, umsebenzisi uya kubona umnqamlezo obomvu. Kulo mzekelo, kucetyiswa ukulayisha ifayile kwakhona.

Useto kwi "iifayile sum asa" isithuba uyakwazi ukutshintsha xa unqakraza kumba efanelekileyo. Vula ifestile zoKhetho, apho kunokwenzeka ukuseta checksums ukubonisa ezinqwenelekayo zokuqinisekisa novavanyo. Ukuze ube yonke into ecacileyo, kucetyiswa ukuba uX ibhokisi ekuvumela ukuba ubonise checksums asezantsi abasebenzisi kwamagama.

Ngoko ke, lo msebenzi kulula kakhulu nale program. Ekubeni Sinokude abasebenzisi bangenamava ukuqonda.

Inkqubo Checker MD5 File

Le nkampani kwakhona kweli ziko esemthethweni, kodwa oko akuthethi ukuba ufakelo. Thina nje kufuneka kokuyisebenzisa. Isebenzisa igama elifanayo lokuqinisekisa algorithm. Xa ukulanda wefayile ofuna ukukhuphela kwibhodi eqhotyoshwayo asa sum of the original uze uyifake endle yokungqinisisa. Inyathelo elilandelayo - khetha ifayile umsebenzisi anqwenela ukuvavanya ukuba ingqibelelo. Emva ngokunqakraza kwiqhosha "Khangela" uya kufumana umyalezo osisiphumo apho uya kuxelelwa ukuba ngaba checksum yefayili okanye ifayile ulimele akukho umdlalo womdlalo.

Elinye ithuba kukuba ukubala eluncedo i-MD5 udibaniso nayiphi na ifayile kwi khompyutha yakho.

isiphelo

Ngoko ke, oko ingqalelo elithi "checksum". Kwaya kwacaca ukuba kwakutheni ukuze isetyenziselwe. Kuba umsebenzisi-avareji oku kulula ukhetho ukukhangela ingqibelelo ifayile kunye nokuthotyelwa yokuqala. ezibalulekile iluncedo sele ichaziwe zokubala nokuthelekisa phantsi izibalo hashe. I wokuqala uyakwazi ukuthelekisa izixa ezahlukeneyo, kwaye algorithm yesibini omnye kuphela, kodwa oko akuthethi ukuba ufakelo, nto leyo ibaluleke kakhulu yokungabikho amalungelo umlawuli.

Ukuba uza ukufaka indlela yokusebenza, okanye nayiphi na enye imveliso software, qiniseka ukuba ukujonga izibalo asa Kucetyiswa emva kokuba uyilayishe ezantsi zonke iifayile ufakelo. Oku kuya konga ixesha elininzi ixesha, okona kubaluleke kakhulu, imizwa.
