Isibali sekhodi sehashi XXH-128

I-XXH, eyaziwa nangokuthi i-XXHash, iyi-algorithm ye-hash esheshayo, engeyona i-cryptographic eyenzelwe ukusebenza kahle okuphezulu, ikakhulukazi ezimweni lapho isivinini sibaluleke kakhulu, njengokucindezelwa kwedatha, ama-checksum, kanye nokukhonjwa kwedatha. Inguqulo evezwe kuleli khasi ikhiqiza ikhodi ye-hash engu-128 bit (16 byte), evame ukubonakala njengenombolo ye-hexadecimal enamadijithi angu-32.

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-XXH-128 Hash Algorithm

Angisiye isazi sezibalo, kodwa ngizozama ukuchaza lo msebenzi we-hash ngisebenzisa isifaniso abanye ososayensi abangebona izibalo abangasiqonda. Uma ukhetha incazelo yezibalo enembile ngokwesayensi, ngiyaqiniseka ukuthi ungayithola kwenye indawo ;-)

Zama ukucabanga nge-XXHash njenge-blender enkulu. Ufuna ukwenza i-smoothie, ngakho-ke ufaka izithako eziningi ezahlukene. Into ekhethekile ngale blender ukuthi ikhipha i-smoothie efanayo kungakhathaliseki ukuthi uyifaka izithako ezingaki, kodwa uma wenza ngisho nezinguquko ezincane ezithakweni, uzothola i-smoothie enongiwe ngendlela ehlukile ngokuphelele.

Isinyathelo 1: Ukuxuba Idatha

Cabanga ngemininingwane yakho njengeqembu lezithelo ezahlukene: ama-apula, ubhanana, ama-strawberry.

• Uziphonsa ku-blender.
• Uzihlanganisa ngesivinini esikhulu.
• Kungakhathaliseki ukuthi izithelo zazinkulu kangakanani, ugcina une-smoothie encane, exutshwe kahle.

Isinyathelo 2: Isosi Eliyimfihlo - Ukuxuba Ngezinombolo "Zomlingo

Ukuqinisekisa ukuthi i-smoothie (hash) ayibikezeleki, i-XXHash inezela isithako esiyimfihlo: izinombolo ezinkulu "zomlingo" ezibizwa ngokuthi ama-primes. Kungani ama-primes?

• Zisiza ekuhlanganiseni idatha ngokulinganayo.
• Zenza kube nzima ukuguqula izithako zokuqala (idatha) kusukela ku-smoothie (hash).

Isinyathelo 3: Ukukhulisa Isivinini: Ukusika Inqwaba

I-XXHash ishesha kakhulu ngoba esikhundleni sokusika isithelo esisodwa ngesikhathi, yona:

• Usika amaqembu amakhulu ezithelo ngesikhathi esisodwa.
• Lokhu kufana nokusebenzisa umshini omkhulu wokugaya ukudla esikhundleni sommese omncane.
• Lokhu kuvumela i-XXHash ukuthi iphathe ama-gigabytes edatha ngomzuzwana - ilungele amafayela amakhulu!

Isinyathelo 4: Ukuthinta Kokugcina: Umphumela We-Avalanche

Nansi imilingo:

• Ngisho noma ushintsha into eyodwa encane (njengekhefana emshweni), i-smoothie yokugcina inambitheka ngendlela ehlukile ngokuphelele.
• Lokhu kubizwa ngokuthi umphumela we-avalanche: Izinguquko ezincane = umehluko omkhulu ku-hash. Kufana nokufaka ithonsi lombala wokudla emanzini, futhi ngokuzumayo yonke ingilazi ishintsha umbala.

Ukufunda Okuqhubekayo

Uma ukujabulele lokhu okuthunyelwe, ungaphinda uthande lezi ziphakamiso:

• Isibali sekhodi sehashi HAVAL-256/3
• Isibali sekhodi sehashi SHA3-384
• Isibali sekhodi sehashi Tiger-128/3
