Isibali sekhodi sehashi XXH3-64

I-XXH, eyaziwa nangokuthi i-XXHash, iyi-algorithm ye-hash esheshayo, engeyona i-cryptographic eyenzelwe ukusebenza okuphezulu nokusebenza kahle, ikakhulukazi ezimweni lapho isivinini sibucayi, njengokucindezelwa kwedatha, ama-checksums, kanye ne-database indexing. Uhlobo olwethulwe kuleli khasi yinguqulo ye-XXH3 ethuthukisiwe. Ikhiqiza ikhodi ye-hash ye-64 bit (8 byte), ngokuvamile ebonakala njengenombolo ye-hexadecimal yedijithi ye-16.

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-XXH3-64 Hash Algorithm

Angiyena isazi sezibalo, kodwa ngizozama ukuchaza lo msebenzi we-hash ngisebenzisa umfaniswano ukuthi ozakwethu abangewona izazi zezibalo bangaqonda. Uma ukhetha incazelo yezibalo elungile ngokwesayensi, egcwele, ngiyaqiniseka ukuthi ungathola lokho kwenye indawo ;-)

Zama ukucabanga XXHash njengoba blender enkulu. Ufuna ukwenza i-smoothie, ngakho-ke ungeza inqwaba yezithako ezahlukene. Into ekhethekile ngale blender ukuthi ikhipha i-smoothie yobukhulu obufanayo kungakhathaliseki ukuthi zingaki izithako ozifaka kuyo, kodwa uma wenza ngisho nezinguquko ezincane nje kwizithako, uzothola i-smoothie ehluke ngokuphelele enongiwe.

Isinyathelo 1: Ukuxuba Idatha

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

• Uziphonsa zibe yi-blender.
• Uzihlanganisa ngesivinini esikhulu.
• Kungakhathaliseki ukuthi izithelo zazizinkulu kangakanani, uqeda nge-smoothie encane, exutshwe kahle.

Isinyathelo 2: I-Sauce Eyimfihlo - Ukugqugquzela ngezinombolo "Zomlingo"

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

• Basiza ngokuxuba idatha ngokulinganayo.
• Benza kube nzima ukubuyisela emuva-unjiniyela izithako zokuqala (idatha) kusuka ku-smoothie (hash).

Isinyathelo 3: Speed Boost: Ukusika e Bulk

I-XXHash i-super fast ngoba esikhundleni sokusika isithelo esisodwa ngesikhathi, it:

• Chops amaqembu amakhulu izithelo zonke ngesikhathi esisodwa.
• Lokhu kufana nokusebenzisa iprosesa enkulu yokudla esikhundleni sokumese omncane.
• Lokhu kuvumela i-XXHash ukuthi iphathe ama-gigabytes wedatha ngomzuzwana - ephelele kumafayela amakhulu!

Isinyathelo 4: Ukuthinta Kokugcina: Umphumela we-Avalanche

Nanku umlingo:

• Ngisho noma ushintsha into eyodwa nje encane (njenge-comma emusho), i-smoothie yokugcina inambitheka ihluke ngokuphelele.
• Lokhu kubizwa ngokuthi umphumela we-avalanche:
  • Izinguquko ezincane = umehluko omkhulu ku-hash.
  • Kufana nokwengeza ithonsi lombala wokudla emanzini, futhi ngokuzumayo yonke ingilazi ishintsha umbala.
