Hash ikhodi wokubala esebenzisa Hash of Variable Ubude 192 bits, 4 rounds (HAVAL-192 / 4) hash umsebenzi ukubala ikhodi hash esekelwe umbhalo okokufaka noma ifayela ukulayisha.HAVAL-192/4 Hash Code Calculator
I-HAVAL (Hash of Variable Length) ngumsebenzi we-hash we-cryptographic owenzelwe nguYuliang Zheng, uJosef Pieprzyk, noJennifer Seberry ngo-1992. Kuyisandiso somndeni we-MD (Message Digest), ophefumulelwe ngokuqondile yi-MD5, kodwa ngokuthuthuka okukhulu kokuguquguquka nokuphepha. Kungakhiqiza amakhodi we-hash obude obuguquguqukayo kusuka ku-128 kuya ku-256 bits, ukucubungula idatha ku-3, 4 noma i-5 rounds.
Uhlobo olwethulwe kuleli khasi lukhipha ikhodi ye-hash ye-192 bit (24 byte) ebalwe ku-4 rounds. Umphumela ukukhishwa njengenombolo ye-hexadecimal yedijithi engu-48.
Ukudalulwa okuphelele: Angibhalanga ukusetshenziswa okuqondile komsebenzi we-hashi osetshenziswe kuleli khasi. Kungumsebenzi ojwayelekile ofakwe nolimi lokuhlela lwe-PHP. Ngenze isixhumi esibonakalayo sewebhu kuphela ukuze ngisenze sitholakale esidlangalaleni lapha ukuze kube lula.
Mayelana ne-HAVAL Hash Algorithm
Cabanga i-HAVAL njenge-blender enamandla kakhulu eyenzelwe ukuxuba izithako (idatha yakho) ngokuphelele kangangokuthi akekho ongathola iresiphi yokuqala nje ngokubheka i-smoothie yokugcina (i-hash).
Isinyathelo 1: Ukulungiselela Izithako (Idatha Yakho)
Lapho unikeza i-HAVAL idatha ethile - njengomyalezo, iphasiwedi, noma ifayela - ayifaki nje ku-blender njengoba-injalo. Okokuqala, it:
- Ihlanza futhi i-chops idatha ibe izingcezu ezihlanzekile (lokhu kubizwa ngokuthi i-padding).
- Kwenza isiqiniseko sokuthi usayizi ophelele ufanelana ne-blender ngokuphelele (njengokuqinisekisa ukuthi izithako ze-smoothie zigcwalisa imbiza ngokulinganayo).
Isinyathelo 2: Ukuxuba ku-Rounds (Ukuxuba Ukudlula)
I-HAVAL ayicindezeli nje "ingxube" kanye. Ihlanganisa idatha yakho ngokusebenzisa i-3, i-4, noma i-5 rounds - njengokuhlanganisa i-smoothie yakho izikhathi eziningi ukuqinisekisa ukuthi yonke i-chunk i-pulverized.
- Ukudlula kwe-3: Ingxube esheshayo (esheshayo kodwa engaphephile kakhulu).
- Ukudlula kwe-5: Ingxube ye-super-thorough (ehamba kancane kodwa evikelekile kakhulu).
Umjikelezo ngamunye uhlanganisa idatha ngokuhlukile, usebenzisa "izindwani" ezikhethekile (imisebenzi yezibalo) ezisika, ziphenduke, zivuselele, futhi zihlanganise idatha ngezindlela ezihlanyayo, ezingalindelekile.
Isinyathelo 3: I-Sauce eyimfihlo (Umsebenzi Wokucindezela)
Phakathi kokuhlanganisa imijikelezo, i-HAVAL inezela isoso layo eliyimfihlo - izindlela zokupheka ezikhethekile ezivusa izinto nakakhulu. Lesi sinyathelo siqinisekisa ukuthi ngisho noshintsho oluncane kwidatha yakho (njengokushintsha uhlamvu olulodwa kwiphasiwedi) lwenza i-smoothie yokugcina ihluke ngokuphelele.
Isinyathelo 4: I-Smoothie Yokugcina (I-Hash)
Ngemuva kwakho konke ukuxuba, i-HAVAL ithululela "i-smoothie" yakho yokugcina.
- Lena hash - umunwe esiyingqayizivele idatha yakho.
- Kungakhathaliseki ukuthi idatha yakho yasekuqaleni yayinkulu noma incane kangakanani, i-hash ihlala usayizi ofanayo. Kufana nokubeka noma yiziphi izithelo zesayizi ku-blender kodwa njalo ukuthola inkomishi efanayo ye-smoothie.
Kusukela ngo-2025, i-HAVAL-256 / 5 kuphela esabhekwa njengephephile enengqondo ngezinhloso ze-cryptographic, nakuba kungafanele uyisebenzise lapho uklama izinhlelo ezintsha. Uma usayisebenzisa ohlelweni lwefa awusengozini esheshayo, kodwa cabanga ukufudukela kuyo isibonelo i-SHA3-256 esikhathini eside.
