I-infographic ye-algorithm ye-SHA-224 elula ukuyilandela: idatha yokufaka iyahlanganiswa futhi ihlukaniswe ngamabhulokhi emiyalezo, icutshungulwe ngemijikelezo ephindaphindwayo kanye nokuxubana kwesimo sangaphakathi, futhi ikhishwe njenge-digest engaguquki engu-224-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.
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
I-infographic ehlanzekile, enefomethi ye-landscape enesizinda se-gradient eluhlaza okwesibhakabhaka kanye nesihloko esikhulu esigxile phezulu esifundeka ngokuthi “SHA-224 Hash Algorithm,” esine-“SHA-224” ngombala omhlophe kanye ne-“Hash Algorithm” ngombala ophuzi/owolintshi ofudumele. Umdwebo ubekwe kusukela kwesobunxele kuya kwesokudla epayipini, kusetshenziswa amabhokisi ayindilinga, imicibisholo, kanye nezithonjana ezilula ukubona ngeso lengqondo ukuthi idatha iba kanjani i-hash yobude obungaguquki.
Ngakwesobunxele kakhulu kunefolda enesitayela ebhalwe ukuthi “Idatha Yokufaka.” Ifolda ivuliwe futhi iqukethe izithonjana eziningana ezibonakalayo, zohlobo lwefayela olujwayelekile: inqwaba yedokhumenti, imvilophu, isithonjana esincane sesithombe, kanye nenothi lomculo, okusho ukuthi izinhlobo eziningi zokuqukethwe zingashintshwa. Umcibisholo ojiyile ukhomba kusuka kule folda uye esigabeni esilandelayo.
Okulandelayo isigaba esibhalwe ukuthi “Amabhulokhi Omyalezo,” esibekwe ngaphezu kwama-rectangle amathathu ahlanganisiwe, ayindilinga amele idatha eqoqwe ngama-cut. Ama-rectangle anemibala futhi abhalwe ukuthi “Ibhulokhi 1,” “Ibhulokhi 2…,” kanye nokuthi “Ibhulokhi 3.” I-bracket noma uhlaka oluncane luzungeza i-stack, lugcizelela ukuhlanganiswa. Ngaphansi kwale ndawo, umcibisholo ogobile kanye nesihloko esithi “Padding & Preprocessing,” okubonisa ukuthi okokufaka kulungiselelwe ngaphambi kokuba kuhlukaniswe ngama-block.
Umcibisholo omkhulu uhola usuka emabhulokhi emiyalezo uye engxenyeni ephakathi yesithombe: iphaneli evelele, ekhanyayo enesihloko esithi “Hash Computation.” Ngaphakathi kwale phaneli, amabhokisi amathathu enqubo ayindilinga ahleli emgqeni eduze kwaphezulu: “Ukuxuba,” “Ukushintsha,” kanye “Nemisebenzi Enengqondo.” Ngayinye yalezi inomcibisholo omncane obheke phansi odla ibha ende evundlile ebhalwe ukuthi “Isimo Sangaphakathi,” okuphakamisa ukuthi le misebenzi iguqula isimo esishintshayo esabiwe. Ngaphansi kokugeleza okuphakathi, umcibisholo obanzi udlula phansi ngelebula ethi “64 Rounds of Processing,” esho ngokubonakalayo ukuphindaphinda okuphindaphindiwe ngesikhathi se-hashing.
Ngakwesokudla kakhulu, umcibisholo wokugcina ukhomba kunxande oluhlaza okotshani, oyindilinga obhalwe ukuthi “Umphumela Wokugcina,” ogcwele imigqa yezinombolo ezimbili (0s kanye no-1s) ukuze kufanekiselwe ukugaywa. Ngaphansi noma eduze kwaleli bhulokhi lokukhipha kukhona umbhalo ofundwayo othi “224-bit Hash Value” kanye nesihlokwana esincane esithi “Unique Fixed-Length Digest,” okuqinisekisa ukuthi umphumela uyiminwe yosayizi ohleliwe. Isitayela sonke singesesimanje futhi siyafinyeleleka, sinezithunzi ezithambile, ukuthayipha okuhlanzekile, kanye nemicibisholo ecacile eqondisa indlela exhumanisa isigaba ngasinye kusukela kokufaka kuya ku-hash yokugcina.
