I-infographic yesimo sendawo enesinqumo esiphezulu echaza ukuhamba komsebenzi kwangaphakathi kwe-algorithm ye-hash ye-HAVAL-256/4, kusukela kumabhulokhi okufaka ahlanganisiwe ngokusebenzisa ama-pass amane ahambisanayo kuya ku-digest yokugcina engu-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
Isithombe siyi-infographic ebanzi, egxile endaweni enesihloko esithi \"HAVAL-256/4 Hash Algorithm\" evezwe ngombala oluhlaza okwesibhakabhaka, oluhlaza okwesibhakabhaka, nowolintshi wesikhathi esizayo. Sibona umbhobho wokucubungula ogcwele womsebenzi we-HAVAL cryptographic hash olungiselelwe ukuphuma okungu-256-bit kanye nama-pass amane. Ngakwesobunxele eside, isithonjana sedokhumenti esinesitayela esibhalwe ukuthi \"Umyalezo Wokufaka\" siphakela esigabeni esibizwa ngokuthi \"I-Padding & Length Append\", lapho umlayezo unwetshwa khona ngephethini enama-binary ephela ensimini enobude obungu-1-bit kanye no-64-bit. Lo mlayezo onama-pad uqoqwe waba yi-\"512-bit Blocks\" ephawulwe ngokucacile, eboniswe njengamaphaneli aluhlaza ahlanganisiwe anephethini yesampula ye-bit efana ne-101010...1 kanye nelebula elincane eliphawula ubude obunama-bit angu-64 obuhlanganisiwe.
Ngaphansi kwalokhu, inqwaba eqondile ebhalwe ukuthi \"Block 1\", \"Block 2\", \"Block 3\", kanye \"Block N\" imele ukulandelana kwamabhulokhi emiyalezo ageleza ku-algorithm eyinhloko. Imicibisholo iqondisa umfundi kusuka kula mabhulokhi aye endaweni yokucubungula ephakathi. Esikhungweni esiphezulu somdwebo, iphaneli yensimbi enesihloko esithi \"Initial Hash Values\" ibonisa amarejista amane e-orange aphawulwe ngokuthi A0, B0, C0, kanye no-D0, okubonisa amagama okuqala isimo sangaphakathi. Umcibisholo ojiyile ukhomba phansi kusuka kula marejista uye enkabeni yokubala eyinhloko.
Isifunda esimaphakathi siphethwe uhlaka olukhulu olubhalwe ukuthi \"Amaketanga Amane Ahambisanayo\". Ngaphakathi kwalo, imizila emine enemibala ebizwa ngokuthi i-R1, i-R2, i-R3, kanye ne-R4 ihamba ngokuvundlile, ngayinye ixhunywe yizithonjana ezincane ze-chain-link ukugcizelela ubunjalo bazo obuhambisanayo. Ngaphakathi komzila ngamunye kukhona ukulandelana kwamabhulokhi omsebenzi afana ne-F1, i-F2, i-F3, i-F4, kanye nezinguquko ezifana ne-P3, nemicibisholo ewaxhumanisa isinyathelo ngesinyathelo. Ngakwesokudla kwale mizila kukhona amalebula afana ne-\"20-bit rotate\", \"30-bit rotate\", kanye \"namagama angu-32-bit\", aqokomisa ukujikeleza kwangaphakathi kanye nokusebenza kwamagama okusetshenziswa ngesikhathi somjikelezo ngamunye. Imisebenzi kanye nokujikeleza kufakwe amakhodi ombala oluhlaza okotshani, o-orenji, onsomi, kanye nohlaza okwesibhakabhaka ukuze kuhlukaniswe ngokubonakalayo amaphasi ahlukene kanye nokuguqulwa.
Ngaphansi kwalezi zintambo ezine kukhona isigaba esinesihloko semishini esinesihloko esithi \"Amaphasi angu-4 / Ama-Round angu-256\" esiboniswe ngezithonjana ezincane zegiya, siqinisa umqondo wokucubungula okuphindaphindiwe. Le ndawo ifaka isibhengezo esinesibindi esifundeka ngokuthi \"Ama-Round angu-256 Okucubungula\", esixhuma ebhokisini eliphuzi eligqanyisiwe elibonisa izibuyekezo ezingokomfanekiso kumarejista wombuso, abhalwe u-A, B, C, no-D, ngemicibisholo ekhombisa ukuhlanganiswa nokubuyekezwa kwala manani.
Ngakwesokudla kakhulu, iphaneli eluhlaza ekhanyayo enesithonjana se-padlock ibhalwe ukuthi \"HAVAL-256/4 Output\". Ngaphakathi kwayo, imigqa emine yezinhlamvu ze-hexadecimal njenge-E9A5D74F, 2B16D3EC, 4F7812A1, kanye ne-A89C64B5 zibekwe ndawonye ukuze zakhe inani le-hash elingu-256-bit. Isihloko ngaphansi kwale phaneli sifunda ukuthi \"256-bit Hash Value\", okucacisa umphumela wokugcina we-algorithm.
Ingemuva liqukethe ukuthungwa okumnyama, okufana nesitayela sebhodi lesekethe okunezintambo ezimbili ezingabonakali kanye nemigqa yokuxhuma ekhanyayo, okuqinisa itimu ye-cryptographic neyedijithali. Imicibisholo emhlophe kanye nezixhumi ziqondisa iso kusukela kwesobunxele kuye kwesokudla kuyo yonke inqubo, okwenza idatha iyonke igeleze—kusukela ekufakweni komyalezo ongahluziwe, ngokusebenzisa i-padding, ukuhlukaniswa kwamabhulokhi, ukudlula kwe-hash okuhambisanayo, imijikelezo eminingi yokucubungula, futhi ekugcineni kuya ekugayweni okuphephile kwe-256-bit—kulula ukuyilandela ngokushesha.
