I-infographic yesimo sendawo enesinqumo esiphezulu echaza i-algorithm ye-MD2 hash enezigaba ezicacile nezilula kusukela kumyalezo wokufaka kuya kunani lokugcina le-hash.

Leli khasi lihunyushwe ngomshini lisuka esiNgisini ukuze lenze lifinyeleleke kubantu abaningi ngangokunokwenzeka. Ngeshwa, ukuhumusha ngomshini akukabi ubuchwepheshe obuphelele, ngakho-ke amaphutha angenzeka. Uma uthanda, ungabuka inguqulo yokuqala yesiNgisi lapha:

MD2 Hash Algorithm — Visual Overview

I-infographic ekhombisa ukugeleza kwe-algorithm ye-MD2 hash kusuka kumlayezo wokufaka ngokusebenzisa amabhulokhi edatha, i-padding kanye ne-checksum, imijikelezo yokuxuba i-state array, kanye nokukhishwa 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 iveza umbono ohlanzekile, olula ukuwulandela we-algorithm ye-MD2 hash. Isihloko esigqamile phezulu maphakathi sifunda ukuthi \"MD2 Hash Algorithm\" ngezinhlamvu ezinkulu ezimhlophe neziphuzi ngokumelene nesizinda se-gradient esibushelelezi esiluhlaza okwesibhakabhaka, sikhomba ngokushesha isihloko. Lonke umdwebo ugeleza kusukela kwesobunxele kuya kwesokudla usebenzisa imicibisholo emhlophe ejiyile ukukhombisa ukuthi idatha ihamba kanjani nge-algorithm.

Ngakwesobunxele impela, isithonjana sedokhumenti ephuzi esifakwe isitayela esibhalwe ukuthi \"Umyalezo Wokufaka\" simele idatha yokuqala enikezwe ngumsebenzisi. Ngaphansi kwayo kunephaneli eluhlaza okwesibhakabhaka enesihloko esithi \"Amabhulokhi Edatha\" equkethe izithonjana eziningana ezincane zamabhulokhi angunxande, okubonisa ukuthi umlayezo uhlukaniswe kanjani ngomqondo ube yizingcezu zosayizi ozinzile ngaphambi kokucutshungulwa. Umcibisholo obheke phansi uholela kusuka kula mabhulokhi kuya kuphaneli emnyama ebhalwe ukuthi \"I-Padding & Checksum.\" Le phaneli iqukethe izingxenye zebha ezinemibala emifushane kanye negama elithi \"I-Checksum,\" elibonisa ukuthi ulwazi olwengeziwe lungezwa kumlayezo ukuze kulungiselelwe i-hashing ngaphandle kokucwila ezintweni ezithile zokusetshenziswa ezibuthakathaka.

Kusukela ohlangothini lwesobunxele lwesithombe, umcibisholo omkhulu omhlophe ukhomba maphakathi lapho kuboniswa khona ibhokisi elivelele elibhalwe ukuthi \"128-Byte State Array\". Ngaphakathi kwaleli bhokisi kukhona igridi yezikwele ezincane, ezinombala okhanyayo oluhlaza okwesibhakabhaka, oluhlaza okotshani, o-orenji, omhlophe, nophuzi. Igridi ayibonakali ngamabomu, ifanekisela inkumbulo yesimo sangaphakathi kunokubonisa noma yimaphi amanani aqondile. Umfanekiso womcibisholo oyindilinga ngaphansi kwegridi ubonisa izibuyekezo zangaphakathi eziphindaphindwayo kanye nokujikeleza kwedatha kwangaphakathi.

Uma siqhubekela phambili kwesokudla, omunye umcibisholo uholela esigabeni esinesihloko esithi \"Izindilinga Zokuguqulwa.\" Lapha, izithonjana eziningana zegiya ezixhumene ngombala oluhlaza okwesibhakabhaka nowolintshi zihlelwe ngendlela efana nesiyingi. Imicibisholo egobile ezungeze amagiya kanye nesihloko esithi \"Ukuxuba Nokuvumela\" kukhombisa ukuthi isimo siguqulwa ngokuphindaphindiwe ngemisebenzi yangaphakathi. Le ngxenye yomklamo idlulisela umqondo wobunzima nokusabalalisa ngaphandle kokudalula amapharamitha obuchwepheshe abucayi noma athambekele emaphutheni.

Ekugcineni, ngakwesokudla kakhulu, inqubo iphela ebhokisini eliluhlaza elibhalwe ukuthi \"Umphumela Wokugcina we-Hash.\" Ngaphakathi kwaleli bhokisi, isampula yesibambi se-hash esifana ne-\"Inani le-Hash: 9AF7B3C5D…\" siboniswa ngokugqamile, sigcizelela ukuthi i-algorithm ikhiqiza ukugaywa kobude obungaguquki. I-ellipsis elandelanayo ikwenza kucace ukuthi inani libonisa kuphela.

Sekukonke, i-infographic isebenzisa ikhodi yombala ehambisanayo, amafonti amakhulu afundekayo, kanye nombhalo omncane ukudlulisa ukugeleza komqondo kwe-algorithm ye-MD2 hash: kusukela kumyalezo wokufaka, ukuwuhlukanisa ube amabhlogo, ukuwulungiselela nge-padding kanye ne-checksum, ukubuyekeza isimo sangaphakathi ngokusebenzisa imijikelezo eminingi yokuguqulwa, bese ekugcineni ukhiqiza umphumela we-hash. Umklamo ugwema imininingwane ebuthakathaka noma eqondile kakhulu, kunalokho ugxile encazelweni enembile yezinga eliphezulu efanele abafundi nezethulo.
