Isibali sekhodi ye-hash esisebenzisa umsebenzi we-hash we-Hash of Variable Length 192 bits, 3 rounds (HAVAL-192/3) ukuze kubalwe ikhodi ye-hash ngokusekelwe kokufakwa kombhalo noma ukulayishwa kwefayela.

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:

HAVAL-192/3 Hash Code Calculator

I-HAVAL (i-Hash of Variable Length) umsebenzi we-hash we-cryptographic owaklanywa nguYuliang Zheng, uJosef Pieprzyk, noJennifer Seberry ngo-1992. Iwukunwetshwa komndeni we-MD (Message Digest), ophefumulelwe ngqo yi-MD5, kodwa onentuthuko enkulu ekuguquguqukeni nasekuphepheni. Ingakhiqiza amakhodi we-hash anobude obuguquguqukayo kusukela kuma-bits angu-128 kuya kwangu-256, icubungula idatha ngemijikelezo engu-3, 4 noma 5.

Inguqulo eyethulwe kuleli khasi ikhipha ikhodi ye-hash engu-192 bit (24 byte) ebalwe ngemijikelezo emi-3. Umphumela uba yinombolo ye-hexadecimal enamadijithi angu-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 nge-HAVAL njenge-blender enamandla kakhulu eyenzelwe ukuxuba izithako (idatha yakho) ngokuphelele kangangokuthi akekho ongathola iresiphi yokuqala ngokubheka nje i-smoothie yokugcina (i-hash).

Isinyathelo 1: Ukulungiselela Izithako (Idatha Yakho)

Uma unikeza i-HAVAL idatha ethile - njengomyalezo, iphasiwedi, noma ifayela - ayimane nje iyiphonse ku-blender njengoba injalo. Okokuqala, yona:

Ihlanza futhi inqume idatha ibe yizicucu ezihlanzekile (lokhu kubizwa ngokuthi i-padding).
Iqinisekisa ukuthi usayizi ophelele ulingana kahle ne-blender (njengokuqinisekisa ukuthi izithako ze-smoothie zigcwalisa imbiza ngokulinganayo).

Isinyathelo sesi-2: Ukuhlanganisa Ama-Round (Ukuxuba Ama-Passes)

I-HAVAL ayicindezeli nje "i-blend" kanye. Ixuba idatha yakho ngemijikelezo emi-3, emi-4, noma emi-5 - njengokuxuba i-smoothie yakho izikhathi eziningi ukuqinisekisa ukuthi yonke ingxenye iyagaywa.

Amaphasi ama-3: Ingxube esheshayo (esheshayo kodwa engaphephile kakhulu).
Amaphasi ama-5: Ingxube ephelele (ehamba kancane kodwa ephephile kakhulu).

Umjikelezo ngamunye uxuba idatha ngendlela ehlukile, usebenzisa "ama-blade" akhethekile (imisebenzi yezibalo) anquma, aphendule, avuse, futhi ahlanganise idatha ngezindlela ezixakile nezingaqondakali.

Isinyathelo 3: Isosi Eyimfihlo (Umsebenzi Wokucindezela)

Phakathi kokuxuba ama-round, i-HAVAL inezela isosi yayo eyimfihlo - izindlela zokupheka ezikhethekile ezivuselela izinto nakakhulu. Lesi sinyathelo siqinisekisa ukuthi ngisho noshintsho oluncane kudatha yakho (njengokushintsha uhlamvu olulodwa kuphasiwedi) kwenza i-smoothie yokugcina ihluke ngokuphelele.

Isinyathelo 4: I-Smoothie Yokugcina (I-Hash)

Ngemva kwakho konke ukuxuba, i-HAVAL ithulula "i-smoothie" yakho yokugcina.

Lena yi-hash - umunwe oyingqayizivele wedatha yakho.
Kungakhathaliseki ukuthi idatha yakho yokuqala yayinkulu noma incane kangakanani, i-hash ihlala ilingana. Kufana nokufaka noma yisiphi isithelo ku-blender kodwa njalo uthola inkomishi efanayo ye-smoothie.

Kusukela ngo-2025, yi-HAVAL-256/5 kuphela esabhekwa njengephephile efanelekile ngezinjongo ze-cryptographic, yize kungafanele uyisebenzise lapho uklama izinhlelo ezintsha. Uma usayisebenzisa ohlelweni oludala awukho engcupheni esheshayo, kodwa cabanga ngokuthuthela ku-SHA3-256 esikhathini eside.
