Ukuboniswa kwesimo sendawo okunesinqumo esiphezulu kwe-HAVAL-160/4 hash algorithm, okubonisa ukucubungula kokufaka, amaphasi okucubungula amane anezinyathelo ezingu-128, ukuguqulwa kokugcina, kanye nokukhishwa kwe-hash okungu-160-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.
Usayizi ojwayelekile (1,536 x 1,024)

Incazelo yesithombe
Isithombe siyi-infographic enesinqumo esiphezulu, egxile endaweni ezungezile echaza i-algorithm ye-hash ye-HAVAL-160/4 njengepayipi lokucubungula elisuka kwesobunxele liye kwesokudla. Uhlelo lombala oluphelele lusebenzisa ingemuva eliluhlaza okwesibhakabhaka elijulile elinegridi ethambile, elinikeza ukubukeka kobuchwepheshe, kwesayensi yekhompyutha. Izihloko ezinkulu zesigaba zihamba phezulu, ziqondisa umbukeli kule nqubo: “Umyalezo Wokufaka,” “Ukugoqa Nokuhlukanisa,” “Ukucubungula Ama-Round,” “Ukuguqulwa Kokugcina,” kanye “ne-Hash Yokugcina.”
Ngakwesobunxele kakhulu, i-"Input Message" iboniswa njenge-cube noma i-stack enezinhlangothi ezintathu egcwele imigqa yezinombolo ezimbili. I-cube ihlezi epulatifomu ekhanyayo, iqinisa umqondo wedatha yedijithali eluhlaza. Kusukela kuleli bhulokhi, umcibisholo ophuzi ovelele ukhomba ngakwesokudla esiteji se-"Padding & Splitting", okubonisa ukuthi umlayezo ulungisiwe futhi uhlukaniswe ngaphambi kokufaka i-hashing. Ngakwesokudla nje kwe-cube, kuvela ilebula ethi "Message Blocks" eduze komcibisholo obanzi, okhanyayo okhomba endaweni eyinhloko yokucubungula, okuphakamisa ukuthi umlayezo ocutshunguliwe uphathwa ngesimo sebhulokhi njengoba ungena emsebenzini wokucindezela.
Ingxenye ephakathi nenkulu kunazo zonke ye-infographic ihlelwe njengephaneli elilodwa elinesihloko esithi “Izindilinga Zokucubungula.” Ngaphakathi kwaleli phaneli kukhona amakholomu amane aqondile abhalwe ukuthi “Umjikelezo 1,” “Umjikelezo 2,” “Umjikelezo 3,” kanye “nomjikelezo 4,” amelela ngokubonakalayo amaphasi amane e-HAVAL-160/4. Ngaphansi kwelebula ngayinye eyindilinga, ibhokisi elincane lesihloko lifundeka ngokuthi “Imisebenzi Engeyona Eyomugqa,” okubonisa ukuthi iphasi ngalinye lisebenzisa umsebenzi ohlukile wokuxuba ongeyona eyomugqa. Ikholomu ngayinye iqukethe imigqa ehlanganisiwe yamabhulokhi amancane, anombala okhanyayo kanye nezithonjana ezixhunywe yimicibisholo. Amabhulokhi afaka izimpawu ezifana nezimpawu ze-plus, amabakaki ane-engile, kanye namathayili anezinhlamvu, amele imisebenzi evamile ye-hash efana nokwengeza kwe-modular, ukuxubana kwe-bitwise, ukufakwa kwamagama omyalezo, kanye nokuguqulwa okufana nokushintshashintsha/ukushintsha. Imicibisholo ikhombisa ukuqhubekela phambili okuya phansi ngaphakathi komjikelezo ngamunye futhi ifaka nokuxhumeka okuseceleni, okubonisa izibuyekezo zesimo esiphindaphindayo kanye nempendulo yangaphakathi njengoba i-algorithm iqhubeka isinyathelo ngesinyathelo.
Ngaphansi kwephaneli yokucubungula eyinhloko, umbhalo ogqamile ufundeka kanje “Izinyathelo eziyi-128 (Amaphasi ama-4),” ugcizelela isakhiwo esilungisiwe salolu hlobo lwe-HAVAL: amaphasi amane ahlanganisa izinyathelo eziyi-128 zokuguqulwa. Ukuhlelwa okubonakalayo kusikisela ukuthi iphasi ngalinye linikela ngokulandelana okuphindaphindiwe kwemisebenzi, kanye nesimo sokunamathelana sishintsha njengoba sihamba phakathi kwamakholomu.
Ngakwesokudla kwephaneli yokucubungula, umcibisholo ophuzi obhalwe ukuthi “Ukuguqulwa Kokugcina” ukhomba engxenyeni yokukhipha. Indawo ethi “Ukuphela Kwe-Hash” ingunxande oluhlaza okwesibhakabhaka oluhlaza okwesibhakabhaka obhalwe ukuthi “HAVAL-160/4 HASH.” Ngaphakathi kwayo, imigqa emibili yezinhlamvu ezinkulu, ezibomvu ngokusawolintshi ze-hexadecimal iboniswa njengesibonelo sokugaywa. Ngaphansi kokukhipha kwe-hex, umbhalo omncane uphinda izakhiwo ezibalulekile: “- 160-Bit Hash Value” kanye “- 4 Passes,” okuqinisekisa kokubili usayizi wokukhipha kanye nenani lamaphasi asetshenzisiwe. Sekukonke, i-infographic iveza i-HAVAL-160/4 njengombhobho ocacile, ohleliwe: idatha yokufaka ye-binary iyahlanganiswa futhi ihlukaniswe ngamabhulokhi, icutshungulwa ngamaphasi amane angewona aqondile anezinyathelo ezingu-128, bese iguqulwa ibe yinani lokugcina le-hash le-160-bit.
