Ukuboniswa okucacile kwe-infographic kwe-algorithm ye-MD4 hash, okubonisa indlela umlayezo wokufaka ohlanganiswa ngayo, ocutshungulwa ngayo, futhi oguqulwa ngayo ube yinani le-hash elingu-128-bit.
MD4 Hash Algorithm – High-Level Visual Overview
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, egxile endaweni enesihloko esithi "MD4 Hash Algorithm" ebekwe ngemuva eliluhlaza okwesibhakabhaka elijulile eline-gradient ecashile kanye nokukhanya okuthambile. Isihloko siphakathi phezulu ngezinhlamvu ezinkulu ezimhlophe nezolintshi, okuchaza ngokucacile ukuthi ukubonakala kumayelana ne-algorithm ye-MD4 hash. Ngaphansi kwesihloko, ukwakheka kuhlukaniswe ngezigaba ezintathu eziyinhloko ezivundlile eziqondisa umbukeli kusukela kwesobunxele kuye kwesokudla: Umyalezo Wokufaka, Imijikelezo Yokucubungula, kanye Nokukhipha Kwe-Hash.
Ngakwesobunxele kakhulu, isigaba Somyalezo Wokufaka sibonisa isithonjana sedokhumenti yephepha kanye nesithonjana semvilophu ukumela idatha ejwayelekile. Ilebula yesitayela seribhoni ngaphansi kwayo ifundeka kanje "Idatha noma Umlayezo." Umcibisholo obheke phansi uholela ebhulokini elibhalwe ukuthi "Ukugoqa Nokuqhekeka," eliboniswe njengamabhulokhi amaningana angunxande ahlanganisiwe ngamathoni ampunga, aluhlaza okotshani, kanye nawo-orenji athule, okubonisa ukuthi idatha engenayo ilungisiwe futhi ihlukaniswe yaba yizicucu. Lawa mabhulokhi ahlanganisiwe abese ekhomba maphakathi nesithombe.
Isikhungo sesithombe yindawo ye-Processing Rounds. Phezulu kwalesi sigaba kunezithonjana ezintathu ezilula, ezingaqondakali ezihlelwe kusukela kwesobunxele kuya kwesokudla: i-funnel enemicibisholo ewela kuyo ebhalwe ukuthi "Mixing," iqoqo lezimo nemicibisholo ebhalwe ukuthi "Bitwise Ops," kanye nesethi yamagiya axhumene abhalwe ukuthi "Add & Shift." Lezi zithonjana ziwuphawu oluqondile kunokuba zibe lobuchwepheshe, zigwema noma yimiphi imininingwane esezingeni eliphansi noma engaba yiphutha ngenkathi zisadlulisela umqondo wokuguqulwa okuphindaphindiwe. Umcibisholo omkhulu ugeleza usuka kulezi zithonjana uye esigxotsheni esiqondile samabhulokhi abhalwe ukuthi "Block 1," "Block 2," kanye "Block N," okubonisa ukuthi i-algorithm icubungula izingcezu eziningi zedatha ngokulandelana.
Ngakwesokudla kukhona ingxenye ye-Hash Output. Phezulu kunomugqa wamathayili amane anemibala abhalwe ukuthi "A," "B," "C," kanye no-"D," axhunywe ngemigqa emhlophe kumcibisholo owodwa obheke phansi. Lo mcibisholo ukhomba isimo sensimbi, esiyindilinga esifana nesisekelo esiphakamisa ukuthi umphumela wokugcina uyakhiwa. Ngaphansi kwalokhu kukhona unxande oluhlaza okotshani okhanyayo obhalwe ukuthi "128-bit Hash Value," okwenza usayizi wokukhipha ucace ngendlela ephezulu. Umcibisholo ogobile uholela kusukela kulokhu okukhiphayo emuva uye enkabeni engezansi yesithombe, lapho ibhena eliwolintshi lifundeka khona ngokuthi "Final Hash Result," okuqinisa umqondo wokuthi wonke amabhlogo acutshunguliwe ahlangana abe yi-digest eyodwa yokugcina.
Kuyo yonke i-infographic, imicibisholo emhlophe ixhumanisa isigaba ngasinye, idala ukugeleza okubonakalayo okucacile kusukela kwesobunxele kuye kwesokudla kanye nokuphezulu kuye phansi. Iphalethi yombala iyonke isebenzisa okuluhlaza okwesibhakabhaka ngemuva, okumhlophe kombhalo nemicibisholo, kanye nemibala egqamile efana ne-orenji, eluhlaza, kanye nompunga ukuhlukanisa imiqondo ehlukene. Umklamo uhlanzekile futhi uyafundisa, ugxile ezinyathelweni zomqondo kunemininingwane ye-cryptographic, okwenza kube lula ngabangebona ochwepheshe ukuqonda umqondo oyisisekelo wokuthi i-MD4 iguqula kanjani umlayezo wokufaka ube yinani le-hash elinobude obungaguquki.
