I-infographic yesimo sendawo esibonisa i-algorithm ye-hash ye-HAVAL-256/3, kufaka phakathi i-padding, amabhlogo womyalezo we-1024-bit, ama-pass amathathu okucindezela, ama-round angu-96, imisebenzi yangaphakathi ye-HAVAL, kanye nenani le-hash le-256-bit eliphumelayo.

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:

HAVAL-256/3 Hash Algorithm Overview

I-infographic ekhombisa i-HAVAL-256/3 ene-input padding, amabhlogo angu-1024-bit, ama-pass amathathu ahlanganisa ama-round angu-96, imisebenzi ye-HAVAL, kanye nomphumela wokugcina we-hash ongu-256-bit.

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

I-infographic iwukubonwa kobuchwepheshe okubanzi, okuqondiswe endaweni ethile kwe-HAVAL-256/3 cryptographic hash algorithm, eklanyelwe ngesitayela se-cyber esiluhlaza okwesibhakabhaka nesolintshi sesikhathi esizayo. Ngakwesobunxele eside, ikholomu ebhalwe ukuthi "INPUT DATA" ikhombisa izinombolo ezimbili eziwela ku-funnel ebhalwe ukuthi "PADDING & LENGTH APPENDING", emele isigaba sokucubungula lapho umlayezo wokuqala ufakwe khona futhi ubude bawo be-bit buhlanganisiwe. Ngaphansi kwe-funnel, iphaneli ekhanyayo isho ngokucacile ukuthi "1024-BIT BLOCKS", okubonisa ukuthi umlayezo ofakwe uhlukaniswe ngamabhulokhi angama-1024-bit anosayizi oqondile. Lawa mabhulokhi ageleza phansi aye esigabeni esithi "MESSAGE BLOCKS", ngamabhulokhi ngamanye abhalwe ukuthi B1 kanye ne-B2, lapho imicibisholo iholela khona epayipini elikhulu lokucindezela.

Indawo ephakathi ivalwe ngonxande omkhulu oyindilinga onesihloko esithi "3 PASSES", okugcizelela ukuthi i-HAVAL-256/3 yenza ama-pass amathathu alandelanayo phezu kwebhulokhi ngayinye. Ngaphakathi kwalesi sifunda kunezigaba ezintathu ezivundlile ezibhalwe ukuthi PASS 1, PASS 2, kanye ne-PASS 3, ngasinye sinezisekethe ezincane ezibonisa imisebenzi yokuxuba yangaphakathi. Ngakwesokudla kwalezi zigaba kukhona inqwaba yamabhokisi amancane okubhalisa abhalwe ngamagama anjengo-B, C, D, E, kanye no-F, afanekisela amagama esimo sangaphakathi se-algorithm abuyekezwa ngesikhathi sokucubungula. Ilebula elifunda "96 ROUNDS" livela eduze komphetho ongakwesokudla wendawo yama-pass, okufingqa ukuthi ama-pass amathathu ndawonye aqukethe izinyathelo ezingu-96 eziphelele.

Ngaphansi kwama-pass, ingxenye efakwe uhlaka ebhalwe ukuthi "HAVAL FUNCTION" ihlukanisa imisebenzi eyinhloko ngomjikelezo ngamunye. Ngaphakathi kwayo, umsebenzi f(x, y, z) uboniswa ufaka ochungechungeni lwama-opharetha kufaka phakathi ukwengeza, ukujikeleza, kanye nezimpawu zesitayela sokuphindaphinda, konke kuxhunywe ngemicibisholo ukuze kuboniswe ukuguqulwa okungekho emgqeni okusetshenziswa esimweni. Leli bhulokhi liveza ngokubonakalayo ukuthi amagama omyalezo kanye namarejista angaphakathi ahlanganiswa kanjani futhi avunyelwe phakathi nomjikelezo ngamunye.

Ngakwesokudla kakhulu, imigqa eminingi ekhanyayo ihlangana ibheke kusithonjana esikhulu se-padlock segolide esifakwe ngemuva kwebhodi lesifunda elinesitayela, emele umphumela wokuphepha wenqubo ye-hashing. Ngaphansi kwe-padlock, ibhokisi elivelele lifundeka ngokuthi "256-BIT HASH VALUE", kulandelwe umucu omfushane we-hexadecimal digest oqala ngo-"D95A5B59A335933988A06A96..." ukuze kuboniswe ifomethi yokugcina yokukhipha. Ngaphansi kwe-infographic, isihloko esithi "HAVAL-256/3 HASH ALGORITHM" siboniswa ngokubhala okugqamile. Sekukonke, umdwebo uveza ukugeleza kwedatha okugcwele kusuka kokufakwayo okuluhlaza ngokusebenzisa i-padding, ukucubungula amabhlogo angu-1024-bit, ukucindezela kwama-three-pass ngemijikelezo engu-96, futhi ekugcineni kuya kumphumela we-hash ongu-256-bit ubude obungaguquki, kusetshenziswa imicibisholo namaphaneli anemibala ukwenza isakhiwo nezigaba ze-algorithm kube lula ukuzilandela.
