Isibali sekhodi ye-hash esisebenzisa umsebenzi we-hash we-Jenkins One At A Time (JOAAT) ukuze kubalwe ikhodi ye-hash ngokusekelwe kokufakwa kombhalo noma ukulayishwa kwamafayela.

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:

Umsebenzi we-hash we-JOAAT (Jenkins One At A Time) umsebenzi we-hash ongeyona i-cryptographic owaklanywa nguBob Jenkins, usosayensi wekhompyutha owaziwayo emkhakheni we-algorithms ye-hashing. Usetshenziswa kabanzi ngenxa yobulula bawo, isivinini, kanye nezakhiwo ezinhle zokusabalalisa, okwenza usebenze kahle ekubhekeni ithebula le-hash, ama-checksum, kanye nokukhomba idatha. Ukhipha ikhodi ye-hash engu-32 bit (4 byte), evame ukumelwa njengenombolo ye-hexadecimal enamadijithi angu-8.

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-JOAAT 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 ;-)

Cabanga nge-JOAAT njengokwenza isobho elikhethekile. Une uhlu lwezithako (lolu ulwazi lwakho lokufaka, njengegama noma ifayela), futhi ufuna ukuzixuba ngendlela yokuthi noma ushintsha into eyodwa encane - njengokwengeza usawoti owodwa owengeziwe - ukunambitheka kwesobho kuyashintsha ngokuphelele. Lokhu "kunambitheka" kuyinani lakho le-hash, inombolo ehlukile emele okufakayo.

Umsebenzi we-JOAAT wenza lokhu ngezinyathelo ezine:

Isinyathelo 1: Ukuqala Ngebhodwe Elingenalutho (Ukuqala)

Uqala ngebhodwe elingenalutho lesobho. Ku-JOAAT, leli "bhodwe" liqala ngenombolo 0.

Isinyathelo 2: Ukwengeza Izithako Ngesinye Ngesikhathi (Ukucubungula I-Byte Ngayinye)

Manje, ufaka izithako zakho ngayinye ngayinye. Cabanga ukuthi yonke incwadi noma inombolo kudatha yakho ifana nokufaka izinongo ezahlukene ebhodweni.

Engeza izinongo (engeza inani lencwadi ebhodweni lakho).
Hlanganisa ngamandla (hlanganisa ngokuhlanganisa ukunambitheka kabili ngokunyakaza okukhethekile - lokhu kufana "nokushintsha" kwezibalo.
Engeza ukuphenduka okumangazayo (faka kancane ukungahleliwe - lokhu kungukusebenza kwe-XOR, okusiza ukuxubanisa ingxube).

Isinyathelo 3: Izinongo Zokugcina Eziyimfihlo (Ukuxuba Kokugcina)

Ngemva kokufaka zonke izithako zakho, wenza ezinye izixuku ezimbalwa eziyimfihlo kanye nama-spice shake ukuqinisekisa ukuthi ukunambitheka akubikezelwe. Yilapho i-JOAAT yenza khona izinyathelo ezimbalwa zokugcina zokuxuba nokuxuba ukuqinisekisa ukuthi umphumela uhlukile.

Isinyathelo 4: Ukuhlolwa Kokunambitha (Okukhiphayo)

Ekugcineni, uyayinambitha isobho - noma esimweni sikaJOAAT, uthola inombolo (inani le-hash) emele ukunambitheka okuyingqayizivele kwesobho lakho. Ngisho noshintsho oluncane kakhulu ezithakweni (njengokushintsha uhlamvu olulodwa kokufaka kwakho) luzokunikeza ukunambitheka okuhluke ngokuphelele (inombolo ehluke ngokuphelele).
