Ukuboniswa kwe-HAVAL-128/5 cryptographic hash algorithm okunesinqumo esiphezulu, okubonisa ukugoqa imiyalezo, ama-processing pads amahlanu, ukuguqulwa kwesimo sangaphakathi, kanye nokukhiqizwa kwe-digest engu-128-bit.
HAVAL-128/5 Hash Algorithm – Five-Pass Cryptographic Workflow
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)
Usayizi omkhulu (3,072 x 2,048)
Usayizi omkhulu kakhulu (4,608 x 3,072)
Usayizi omkhulu kakhulu (6,144 x 4,096)
Usayizi omkhulu ngokwe-comic (1,048,576 x 699,051)

Incazelo yesithombe
Isithombe siyi-infographic ebanzi, enesinqumo esiphezulu, egxile endaweni enesihloko esithi "HAVAL-128/5 Hash Algorithm" eboniswe phezulu ngokubhala kwensimbi phezu kwesizinda esiluhlaza okwesibhakabhaka esijulile, sedijithali esigcwele izinombolo ezimbili, imikhondo efana nesekethe, kanye nemifudlana yedatha ekhanyayo. Ngaphansi kwesihloko, umbhalo ongezansi ufundeka kanje "Ama-Passes ama-5 / Isimo sama-Bit angu-128," ohlela ngokushesha isakhiwo se-algorithm. Konke ukwakheka kuhlelwe kusukela kwesobunxele kuya kwesokudla njengombhobho obonakalayo.
Ngakwesobunxele kakhulu, iphaneli ethi "Umyalezo Wokufaka" ibonisa idokhumenti enesitayela kanye nezithonjana zemvilophu, ezifanekisela idatha yomsebenzisi engena ku-hash function. Umcibisholo uholela phansi ebhulokini elibhalwe ukuthi "Padding & Message Length," eliboniswa njengebha ehlukanisiwe ehlanganisa amabhulokhi aphuzi nawolintshi, elibhalwe ukuthi "Padding + Length," elibonisa isinyathelo sokucubungula esihlanganisa ubude be-1-bit, o-zero, kanye nobude bomyalezo wokuqala ukuze kwakheke umfudlana webhulokhi ophelele.
Kusukela kulesi sigaba sokucubungula, imicibisholo idla ngokulandelana okuvundlile kwamaphaneli amahlanu angunxande phakathi nendawo yesithombe. Abhalwe ngokuthi "Block 1," "Block 2," "Round 3," "Round 4," kanye "Round 5," amelela ngokubonakalayo ama-pass amahlanu e-HAVAL. Ibhulokhi ngayinye ihlukaniswe ngamathayili aluhlaza okwesibhakabhaka negolide ukuze kuboniswe amagama omyalezo kanye namagama esimo sangaphakathi axutshwe. Ngaphezulu kwawo, umbhalo othi "5 PASSES / 128-BIT STATE" ugcizelela ukuthi le misebenzi iphindaphindwa emizuliswaneni emihlanu ukuze kuthuthukiswe inani le-chaining elingu-128-bit.
Imicibisholo eya phansi evela emzuliswaneni ngamunye ihlangana ibe yibhande elikhanyayo elinesihloko esithi "Bitwise Operations." Ngaphansi kwaleli bhande kuvela amabhokisi amancane amahlanu abhalwe ngamagama emisebenzi abhalwe isitayela f1, f3, f4, f5, kanye f5, amelela imisebenzi ehlukene ye-Boolean engeyona eqondile esetshenziswa kuphasi ngalinye le-HAVAL. Lawa adwetshwa njengamathayili aluhlaza okwesibhakabhaka anombala omhlophe, egcizelela ukuthi umzuliswano ngamunye usebenzisa umsebenzi wokuxuba ohlukile.
Umphumela wale misebenzi ugeleza uye kwelinye ibhendi elikhulu elibhalwe ukuthi "Izengezo Ze-Modular." Ngaphansi kwalo kukhona amabhokisi amancane ayisithupha abhalwe ukuthi A, B, C, D, B, kanye no-E, aphakamisa amarejista amaningi okusebenza angaphakathi asetshenziswa yi-HAVAL njengoba ijikeleza futhi inezela amagama athi modulo 2^32. Imicibisholo yegolide ekhanyayo kanye nama-flare okukhanya kusho ukunyakaza kwedatha okuqhubekayo kanye nokuqongelela.
Ngakwesokudla kwe-infographic, iphaneli ende ebhalwe ukuthi "Finalization" ibala "Bit Rotations" kanye "Output Transform," efingqa isigaba sokugcina lapho isimo sangaphakathi sivunyelwe futhi sicindezelwe. Umcibisholo wokugcina obheke phansi uholela ebhokisini elikhazimulayo, elinohlaka olubonisa isampula "128-BIT HASH VALUE" emigqeni emibili yezinhlamvu ze-hexadecimal, njenge-"E7A9B354 32DC3F25 89F63A1E 76B67D90," edlulisa ukugaywa kobude obungaguquki okukhiqizwe kungakhathaliseki usayizi wokufaka.
Uhlelo lombala lushintshashintsha phakathi kombala oluhlaza okwesibhakabhaka opholile wezindlela zedatha kanye negolide elikhanyayo noma i-orenji yokuguqulwa okusebenzayo, okunikeza isithombe ubuhle bobuchwepheshe, obunamandla aphezulu. Ingemuva ligcwele amagridi akhanyayo, imifudlana yabodwa kanye no-zero, kanye ne-circuitry ebuthakathaka, okuqinisa ingqikithi yokucubungula i-cryptographic kanye nokuphepha kwedijithali ngenkathi kudlula umbukeli ngokusobala ngokusebenzisa i-HAVAL-128/5 hashing workflow kusukela ekufakweni komlayezo kuya ekukhishweni kokugcina kwe-128-bit.
