I-infographic ye-landscape echaza i-algorithm ye-JOAAT hash ngokugeleza okulula kwesinyathelo ngesinyathelo kusuka ku-string yokufaka kuya ku-hash value yokugcina.

Leli khasi lihunyushwe ngomshini lisuka esiNgisini ukuze lenze lifinyeleleke kubantu abaningi ngangokunokwenzeka. Ngeshwa, ukuhumusha ngomshini akukabi ubuchwepheshe obuphelele, ngakho-ke amaphutha angenzeka. Uma uthanda, ungabuka inguqulo yokuqala yesiNgisi lapha:

JOAAT Hash Algorithm – Visual Overview

I-infographic ekhombisa ipayipi le-algorithm ye-JOAAT hash kusukela kuma-byte okufaka ngokusebenzisa i-add, i-XOR, kanye ne-shift stages kuya kumphumela wokugcina we-hash.

Izinguqulo ezitholakalayo zalesi sithombe

Amafayela ezithombe atholakalayo ukuze alandwe ngezansi awacindezelwe kakhulu futhi anesisombululo esiphezulu - futhi ngenxa yalokho, ikhwalithi ephezulu - kunezithombe ezifakwe ezihlokweni nasemakhasini akule webhusayithi, ezilungiselelwe kangcono usayizi wefayela ukuze kuncishiswe ukusetshenziswa komkhawulokudonsa.

Incazelo yesithombe

Isithombe siwumfanekiso obanzi, ogxile endaweni ethile oveza ukubonakala kwezinga eliphezulu kwe-algorithm ye-JOAAT hash ngesitayela esihlanzekile nesinobungane. Ukuhlelwa kugeleza kusukela kwesobunxele kuye kwesokudla, kuqondise umbukeli ngomqondo oyinhloko wokuthi intambo yokufaka iguqulwa kanjani kancane kancane ibe yinani le-hash.

Ngakwesobunxele kakhulu, ibhokisi lekhanda eliluhlaza okwesibhakabhaka elibhalwe ukuthi "Input String" lethula indawo yokuqala. Ngaphansi kwalo, umugqa wamathayili ayisikwele abhalwe ngezinhlamvu zesibonelo ezifana no-A, B, C, no-D umele amabhayithi noma izinhlamvu zokufaka. Umcibisholo ngaphansi kwala mathayili kanye nesihloko esifushane kubonisa ukuthi i-algorithm icubungula idatha ngebhayithi elilodwa ngesikhathi, igcizelela ukuthi uhlamvu ngalunye luphathwa ngokulandelana kunokuba luphathwe ngesikhathi esisodwa.

Isigaba esilandelayo isikwele esikhulu esiphuzi esibhalwe ukuthi "ADD" esinophawu lokuhlanganisa phakathi nendawo. Umcibisholo okhomba ngakwesokudla uholela kusuka kumathayili okufaka ungene kuleli bhokisi, ubonisa ngokubonakalayo ukuthi i-byte yamanje ingeziwe enanini le-hash elisebenzayo. Umbala ophuzi kanye nesithonjana esigqamile kwenza lesi sinyathelo sivelele njengengxenye yokuqala yenqubo yokuxuba.

Kusukela kubhulokhi ye-ADD, omunye umcibisholo ukhomba isikwele esiluhlaza okwesibhakabhaka esibhalwe ukuthi "XOR" esinophawu lwe-XOR oluzungelezile. Leli bhulokhi libonisa isinyathelo sokuxuba lapho inani eliqongelelwe lihlanganiswa khona nokufakwayo kusetshenziswa umsebenzi we-exclusive-noma. Umbala oluhlaza okwesibhakabhaka uhlukanisa lo msebenzi nowedlule ngenkathi ugcina iphalethi lihambisana kulo lonke umdwebo.

Ukugeleza bese kuqhubeka kube yisikwele esiluhlaza esibhalwe ukuthi "SHIFT" noma "Rotate & Shift" ngesithonjana sesitayela semicibisholo nefasitela esilula. Lokhu kumelela isigaba sokushintsha noma sokujikeleza kwe-bit esiqhubeka nokuxuba ama-bits enani le-hash. Ndawonye, amabhokisi e-ADD, XOR, kanye ne-SHIFT aqoqwe nge-bracket noma isixhumi ngaphansi kwawo ngesihloko esithi "Hlanganisa & Hlanganisa," okucacisa ukuthi lezi zinyathelo zisebenza ndawonye ukuxuba idatha yokufaka ku-hash eguqukayo.

Ngakwesokudla komdwebo, inqubo iphetha ngebhokisi eliluhlaza okwesibhakabhaka eliyindilinga elibhalwe ukuthi "Umphumela we-Hash" noma "Inani le-Output Hash." Isihloko esiluhlaza okwesibhakabhaka ngaphezulu kwaso sifunda ukuthi "I-Final Hash," nomcibisholo obheke phansi okhomba ebhokisini lemiphumela, okuqinisa ukuthi lokhu kungumkhiqizo wokugcina wepayipi.

Ngaphansi kwesithombe, ibhanela elikhulu, eliluhlaza okwesibhakabhaka elimnyama lihlanganisa ububanzi be-infographic futhi liqukethe isihloko esithi "JOAAT Hash Algorithm," negama elithi "Hash" eligqanyiswe ngombala ophuzi noma wegolide ohlukile. Umklamo jikelele usebenzisa imicibisholo elula, imibala ehluke kakhulu (eluhlaza okwesibhakabhaka, e-orenji, nohlaza), kanye nombhalo omncane ukwenza umqondo ube lula ukuwuqonda ngaphandle kokucwila emininingwaneni ethile yokusetshenziswa. Ithoni ebonakalayo iyafundisa futhi iyangeneka, ifanele abathuthukisi noma abafundi abafuna umbono ophelele wokuthi i-JOAAT iguqula kanjani intambo yokufaka ibe yinani le-hash.
