I-infographic yesimo sendawo echaza ukugeleza kwezinga eliphezulu kwe-algorithm ye-HAVAL hash, kusukela kumyalezo wokufaka kanye namabhulokhi edatha ngokusebenzisa imisebenzi engeyona eqondile, ukuxuba, kanye nokucindezelwa kuya ekuphumeni kwe-hash kokugcina.

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
Le infographic yesimo sendawo inikeza umbono ohlanzekile, osezingeni eliphezulu wokusebenza kwe-HAVAL hash algorithm, eyenzelwe ukuba kube lula ukuyiqonda ngaphandle kokuthembela kumapharamitha ezinombolo aqondile. Ukwakheka kuhlelwe kusukela kwesobunxele kuya kwesokudla, kuqondise umbukeli ekuguqulweni komlayezo wokufaka ube yinani lokugcina le-hash ye-cryptographic. Ngakwesobunxele kakhulu, inqwaba yamakhasi afana nedokhumenti abhalwe ngezinhlamvu zezinhlamvu zesampula imelela umlayezo wokufaka wokuqala. Ngaphansi kwalesi sigaba, amabhokisi ambalwa amancane ayindilinga abonisa izingcezu zedatha ebukeka njenge-binary, egcizelela ukuthi umlayezo uqala ukulungiswa futhi uhlukaniswe ngezingcezu ezilawulekayo. Umcibisholo ukhomba kule ndawo yokufaka uye enkabeni yomdwebo, lapho kuqala khona ipayipi lokucubungula eliyinhloko.
Ngaphezulu kwesithombe kugijima ukulandelana okuvundlile kwezigaba ezilebula, ngasinye sihlukaniswe ngemicibisholo: "Umyalezo Wokufaka" uholela ku-"Padding & Splitting," bese kuba "Hash Rounds," bese kuba "Mixing & Compression," bese kuba "HAVAL Hash Value." Lawa malebula asebenza njengemephu yendlela, efingqa ukugeleza okuphelele ngolimi olulula. Indawo ephakathi ivalwe unxande ozungelezile onezingqimba, ogqamisa imisebenzi yangaphakathi eyenziwa ngokuphindaphindiwe kubhulokhi ngayinye yedatha.
Ngaphakathi kwale ndawo yokucubungula enezinhlayiya kukhona amabhokisi amaningana anemibala amele imisebenzi ehlukene yesitayela esingeyona eye-linear kanye nese-arithmetic esetshenziswa yi-algorithm. Ibhokisi eliphuzi elikhanyayo elibhalwe ukuthi "XOR" livela eduze kwesobunxele esiphezulu sendawo yokucubungula, lixhunywe ngemicibisholo ebhokisini eliluhlaza elibhalwe ukuthi "AND" kanye nebhokisi eliphuzi elibhalwe ukuthi "OR." Ngaphansi kancane kwalokhu kunesimo sesitayela senkulumo esiluhlaza okwesibhakabhaka esibhalwe ukuthi "-F" kanye nesihlokwana esithi "Nonlinear Functions," okubonisa ukuthi umndeni wemisebenzi enengqondo eyinkimbinkimbi usetshenziswa kudatha. Ngezansi kwalokho, ibhokisi eliphuzi elinophawu lokuhlanganisa limelela ukwengeza noma ukuhlanganiswa kwamanani. Imicibisholo ephakathi kwala mabhokisi ihlangana futhi ihlangane, iveza ngokubonakalayo ukuthi idatha igeleza ngokuguqulwa okuningi okunengqondo kunokuba ibe yindlela eyodwa eqondile.
Ngakwesobunxele esingezansi sesifunda esinamadeshi, kuvela imigoqo emithathu evundlile ebhalwe ukuthi "Idatha yeBlock 1," "Ibhloko 2," kanye nethi "Ibhloko 3" ngemibala ehlukene. Lawa mabhlogo axhunywe ngemicibisholo ebhokisini eliluhlaza okwesibhakabhaka eliyindilinga elibhalwe ukuthi "Ukuxuba Nokucindezela," elisenkabeni engezansi. Lesi sigaba sibonisa ukuthi ibhloko ngayinye yedatha elungiselelwe ifakwa kanjani esigabeni sokuxuba esihlanganisa ibhloko yamanje nesimo sangaphakathi esiguqukayo. Izithonjana zamagiya amancane ngemibala eminingi zihlala eduze kohlangothi lwesokudla lwendawo enamadeshi, ezifanekisela izibuyekezo zesimo sangaphakathi kanye nokuguqulwa okuphindaphindiwe.
Kusukela endaweni yokuxuba nokucindezela, umcibisholo uholela phezulu kusithonjana esimise okwe-funnel esibhalwe njengesinyathelo sokugcina sokucubungula, okuphakamisa ukuthi wonke amanani aphakathi ahlanganiswe abe umphumela owodwa. Ngezansi kwale funnel kukhona ibhokisi elibomvu elinesihloko esithi "Final Processing," eliqinisa umqondo wokuthi i-algorithm yenza isigaba sokugcina sokuhlanganiswa. Umcibisholo onesibindi ube usukhomba ngakwesokudla kakhulu kwesithombe, lapho uphawu olumise okwe-shield luqukethe imigqa yezinombolo ezimbili, emele inani lokugcina le-hash. Ngaphansi kwalesi sihlangu, unxande oyindilinga ubonisa isibonelo sentambo efana ne-alphanumeric hash kanye nelebula ethi "Hash Output," okwenza kucace ukuthi umkhiqizo wokugcina uyi-digest yosayizi ohleliwe.
Sekukonke, isithombe sisebenzisa imicibisholo ecacile, imibala ehlukile, kanye nezithonjana ezilula ukuxhumana ngezigaba zomqondo ze-algorithm ye-HAVAL ngaphandle kwemininingwane eminingi yobuchwepheshe. Ukuhlelwa kusuka kwesobunxele kuya kwesokudla, kuhlanganiswe namalebula okufingqa aphezulu kanye nebhokisi lokucubungula langaphakathi elinomugqa, kusiza ababukeli ukuqonda ngokushesha ukuthi umlayezo wokufaka uguqulwa kanjani ngemisebenzi enengqondo, ukuxuba, kanye nokucindezelwa kube yi-hash yokugcina ye-cryptographic.
