I-infographic yesimo sendawo enesinqumo esiphezulu ekhombisa ukuthi i-CRC-32C checksum ibalwa kanjani, kusetshenziswa amabhlogo alula, imicibisholo, namalebula ukubonisa ukugeleza kusuka kudatha yokufaka kuya ekukhishweni kwe-hash kokugcina.
CRC-32C Hash Algorithm – 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 siyisithombe esibanzi, esinesinqumo esiphezulu, esiqondiswe endaweni enesihloko esithi \"CRC-32C Hash Algorithm\" esiboniswe ngokugqamile phezulu ngezinhlamvu ezinkulu, ezikhanyayo ezimhlophe ngemuva okuluhlaza okwesibhakabhaka okumnyama, okunetimu yedijithali egcwele amaphethini amancane kanye nemigqa yegridi. Isitayela sisonke sihlanzekile, sesimanje, futhi sinobuchwepheshe, senzelwe ukuchaza ngokubonakalayo ukugeleza kwe-algorithm ngaphandle kokuthembela emininingwaneni yezinombolo eqondile kakhulu noma engase ibe enganembile.
Ngakwesobunxele eside, ikholomu eqondile ebhalwe ukuthi \"INPUT DATA\" iqukethe amabhokisi amathathu ayindilinga angunxande ahlanganiswe kusukela phezulu kuya phansi, ngalinye libhalwe ukuthi amabhlogo wedatha, njenge-\"Data Block 1\", \"Data Block 2\", kanye ne-\"Data Block 3\". Imigqa emincane yokuxhuma emhlophe ihola kusukela kula mabhlogo iye enkabeni yomdwebo, okubonisa ukuthi amabhlogo acutshungulwa ngokulandelana.
Uma sihamba ngakwesokudla, ingxenye elandelayo enkulu inesihloko esithi \"SHIFT & DIVIDE\". Le ndawo ikhombisa amaphaneli amabili angunxande anemigqa elula yezinombolo ezimbili. Iphaneli ephezulu inezichasiselo ngomcibisholo ogobile kanye negama elithi \"Shift\", elibonisa ngokubonakalayo umsebenzi wokushintsha kancane, kuyilapho iphaneli engezansi ifaka isithonjana esincane sokuhlukanisa kanye negama elithi \"Divide\", elimelela ukuhlukaniswa kwe-polynomial ngendlela engaqondakali. Imicibisholo egqamile ye-accent enombala o-orenji kanye ne-cyan iqondisa iso lombukeli phansi nangakwesokudla, ikhombisa indlela yokucubungula.
Kusukela kumaphaneli okushintsha nokuhlukanisa, i-node enkulu eyindilinga ebhalwe ukuthi \"XOR\" ihlezi phakathi nendawo, idwetshwe ngombala oluhlaza okwesibhakabhaka. Umcibisholo ovela kule node ukhomba ibha ende evundlile esigabeni esilandelayo ebhalwe ukuthi \"CRC REGISTER\". Le bha inesihloko esithi \"Inani Lesikhashana\" futhi iqukethe umugqa wama-bit tile amancane, anemibala eminingi, okuphakamisa isimo se-checksum esishintshayo esigcinwe kurejista ye-CRC. Ama-bits enziwe ngesitayela ngamabomu kunokuba abe aqondile, aqinisa isimo semfundo nesomqondo sesithombe.
Ngakwesokudla kwerejista ye-CRC, kuvela enye i-node eyindilinga ethi "XOR", kulokhu ikhomba ngqo kuphaneli ekhanyayo ephuzi eqondile ebhalwe ukuthi \"CRC-32C Hash\" enesihloko esingezansi esithi \"Checksum Output\". Leli phaneli lokugcina limelela umphumela wokugcina wenqubo, ligcizelela ngokubonakalayo i-checksum yokugcina ebaliwe njengomphumela wepayipi.
Ngaphansi kwesithombe kukhona ukugeleza kwesibili okufingqa iluphu iyonke. Kuvela izimo ezintathu ezimhloshana, ezifana nediski ngakwesobunxele kanye nesihloko esithi \"Cubungula Ibhulokhi Ngayinye\". Umcibisholo uholela esibukweni esincane esingunxande esibhalwe ukuthi \"Buyekeza i-CRC Register\" esibonisa futhi isimo sokushintsha kwamabhithi anesitayela. Omunye umcibisholo ukhomba isithonjana sesitayela seminwe esibhalwe ukuthi \"Final Checksum\", okuqinisa umqondo wesiginesha yedijithali ehlukile etholakala kudatha yokufaka.
Kuyo yonke i-infographic, kusetshenziswa ikhodi yombala ehambisanayo: ama-blues nama-cyan okucubungula kwangaphakathi, ama-orange okukhiphayo nokugcizelela, kanye nombhalo omhlophe ocacile. Imigqa emincane enemigqa kanye nokumbozwa kwegridi okungabonakali kuhlukanisa izingxenye eziyinhloko, okusiza umbukeli ukulandelela ukugeleza kusuka kwesobunxele kuya kwesokudla. Lonke ukwakheka kulinganisela futhi kulula ukukulandela, okunikeza incazelo ebonakalayo yezinga eliphezulu yokuthi i-CRC-32C iguqula kanjani amabhlogo edatha yokufaka ngokushintsha, ukuhlukanisa, imisebenzi ye-XOR, kanye nezibuyekezo zokubhalisa ukuze kukhiqizwe ukuhlolwa kokugcina.
