Vachiongorora hashi inopfupikisa: chii?

Vakawanda vanoshandisa makombiyuta pamusoro nguva, musi pedyo waunoziva, kubvunza hashi-inopfupikisa. Vanodanwa checksum. Chii? Zvaunoda? Sei akaverenga mari chete izvi?

tsananguro

Checksum anonzi vamwe kukosha, iro rinowanikwa nokuda Data achishandisa anokosha algorithms. Chinangwa hashi inopfupikisa - vachiongorora kuvimbika mashoko panguva hutachiwana. Rakajairika algorithms kuti kukarukureta - MD5, CRC32 uye naBhaasha-1. Checksums inogona kushandiswa enzanisa anoita mashoko pamusoro asiri yokuenzana, kushanda, nokuti kuziva miedzo mavhairasi pakombiyuta yako.

The kukurumbira wokushandiswa nzira iyi anowana kubva ndechokuti bvunzo zviri nyore kushandisa mu digitaalinen zvokushandisa, kushanda pamwe binary ezvinhu kukarukureta. It inoongorora pasina dambudziko uye iguru kuwana zvikanganiso kuti zvinokonzerwa pamberi ruzha iri date pamakwara.

Algorithms kuongorora

The MD5 algorithm haisi chete kushandiswa ritsigire kuvimbika data, asi anopa mukana kuwana zvakanaka yakavimbika identifier, iro rinowanzoshandiswa zviitiko apo chete zvinowanikwa pamusoro kombiyuta mafaira. Saka, hapana kuenzanisa zviri, uye avo hashi inopfupikisa.

CRC32 algorithm rinoshandiswa archiving mapurogiramu. It inomira se "cyclic redundancy bumbiro".

NaBhaasha-1 algorithm awana chikumbiro ari ongororo pamusoro date kuvimbika, izvo vakaremerwa pachishandiswa BitTorrent chirongwa.

muenzaniso

Somuenzaniso, mukomana aishandisa anoda kuisa uchishandisa mamiriro kana mutambo pamusoro PC yenyu. It Downloads mufananidzo uye anoda kuti tive nechokwadi chokuti kuvimbika faira kuitira uye kuchinjwa hapana akarasika. Nyore nzira yokuita izvi - kuenzanisa munhu hashi pakati paIndaneti faira, uye mari inopiwa nemunyori. Kana ivo zvinopindirana, mufananidzo harina zvikanganiso. Zvakanaka, kana hashi Verengai mafaira zvakasiyana, zvakakodzera kupomba zvakare, nokuti paiva akundikana.

Ichi chepuraimari nzira chinhu chokudzivirira nechiyero pamusoro kururama basa rakaturikwa. Kumhanya izvozvo, unogona kuva nechokwadi chokuti kugadzwa kushanda ezvinhu, zvirongwa kana mitambo achava akarurama.

Zvinotevera ndizvo kutsanangura utility, kuzvigona dzemaitirwe uye ongororo pamusoro checksums.

HashTab chirongwa: kuongorora hashi pakuverengwa

utility uyu plugin kuti integrates kupinda uchishandisa maitiro uye rinoshandiswa munguva dzokushayiwa. Rinogona kutorwa kubva pamutemo Website zvachose pachena muchimiro chokugadza faira. Kugadzwa purogiramu yacho nzwisisa zvikuru.

Mushure Ndokunyengetererai ehupfumi neimwe faira kuuya mutsva mamwe Tab kuti pakuverenga ari checksum. By default, vachange dzaona vatowanda algorithms vatatu inorondedzerwa pamusoro.

How kuongorora hashi pakuverengwa? Kuti vaite izvi, "Enzanisa" munda dzinoisa mari kwakaratidzwa munyori. Kana paIndaneti faira rave vakabudirira kuongororwa kuti nderechokwadi, nyoro checkmark. Zvikasadaro, inodzidzisa vachaona muchinjikwa mutsvuku. Muchiitiko chino, Zvinokurudzirwa kuti udhanilodhe faira zvakare.

Settings pamusoro "hashi Verengai mafaira" Tab unogona kushandura kana iwe tinya yakakodzera chinhu. Zarura Options hwindo, apo zvinoita kuisa zvinodiwa kuratidza checksums kuti ongororo uye kuongorora. Kuti zvose yakajeka, Zvinokurudzirwa kuti tick ari Checkbox unokubvumira kuratidza checksums lowercase.

Saka, basa riri nyore kwazvo chirongwa ichi. Sezvo unogona ruzivo vanoshandisa kunzwisisa.

MD5 File checkered Program

utility iyi zvakare paIndaneti kubva pamutemo nzvimbo, asi haatarisiri kugadzwa. Tinofanira chete vanofanira kumhanya naro. Inoshandisa zita chete kuti ongororo algorithm. Kana kudhanilodha faira unoda kutevedzera kuti clipboard hashi Verengai chepakutanga uye ipapo dzinoisa panzvimbo ongororo mumunda. Danho rinotevera - kusarudza file inodzidzisa achida kuongorora kuvimbika. Pashure nekudzvanya bhatani "Check" achawana shoko chete mugumisiro izvo uchaudzwa kana checksum faira kana faira wakaremara uye hapana mutambo machisa.

Chimwe chaunogona kuita ngaaverenge utility ari MD5 mubatanidzwa upi faira pakombiyuta yako.

mhedziso

Saka, zvaionekwa rokuti "checksum". Zvakava pachena nei rinoshandiswa. Nokuti avhareji User ichi chiri nyore nezvechisarudzo kuongorora faira vakaperera uye zvaidiwa chepakutanga. chinobatsira utilities vave zvinorondedzerwa kuti pakuverenga uye achienzanisa hashi inopfupikisa. Chokutanga anokwanisa kuenzanisa mari siyana, uye wechipiri chete algorithm, asi haina zvinoda yokugadza, iyo inokosha tisina mutariri kodzero.

Kana uchizopa kuisa uchishandisa hurongwa kana mumwe-software chigadzirwa, iva nechokwadi kuti aone varumbidzwa hashi inopfupikisa pashure kudhanilodha zvose installation mafaira. Izvi achaponesa nguva yakawanda, uye zvakakoshesa, tsinga.
