Isibali sekhodi sehashi Adler-32

Kushicilelwe: 17 Pébruari 2025 jam 18.07.55 UTC

Hash ikhodi wokubala esebenzisa umsebenzi Adler-32 hash ukubala ikhodi hash esekelwe umbhalo okokufaka noma ifayela ukulayisha.

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:

Adler-32 Hash Code Calculator

Umsebenzi we-Adler-32 hash uyi-algorithm ye-checksum elula, esheshayo, futhi evame ukusetshenziselwa ukuqinisekiswa kobuqotho bedatha. Yaklanywa nguMark Adler futhi ivame ukusetshenziswa kwizicelo ezifana ne-zlib yokucindezelwa kwedatha. Ngokungafani nemisebenzi ye-hash ye-cryptographic (njenge-SHA-256), i-Adler-32 ayiklanyelwe ukuphepha kodwa ukuhlola amaphutha okusheshayo. It computes a 32-bit (4 bytes) checksum, ngokuvamile emelelwa njengoba 8 izinhlamvu hexadecimal.

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.


Bala Ikhodi Ye-Hash Entsha

Idatha ethunyelwe noma amafayela alayishwe ngaleli fomu azogcinwa kuseva kuphela uma nje kuthatha ukukhiqiza ikhodi ye-hashi eceliwe. Izosuswa ngokushesha ngaphambi kokuthi umphumela ubuyiselwe esipheqululini sakho.

Idatha yokokufaka:



Umbhalo othunyelwe ubhalwe ngekhodi ye-UTF-8. Njengoba imisebenzi ye-hash isebenza kudatha kanambambili, umphumela uzohluka kunalapho umbhalo ubukomunye umbhalo wekhodi. Uma udinga ukubala i-hash yombhalo ekubhaleni ngekhodi okuthile, kufanele ulayishe ifayela esikhundleni salokho.



Mayelana ne-Adler-32 Hash Algorithm

Angiyena isazi sezibalo, kodwa ngizozama ukuchaza lo msebenzi we-hash ngisebenzisa umfaniswano wansuku zonke engithemba ukuthi ozakwabo abangewona izazi zezibalo bangaqonda. Ngokungafani nemisebenzi eminingi ye-hash ye-cryptographic, i-Adler32 ngumsebenzi olula kakhulu we-checksum, ngakho-ke lokhu akufanele kube kubi kakhulu ;-)

Cabanga ukuthi unesikhwama samathayela amancane anamanani, ngamunye omele incwadi noma ingxenye yedatha yakho. Ngokwesibonelo, igama elithi "Hi" has amathayili amabili: omunye "H" futhi omunye "i".

Manje, sizokwenza izinto ezimbili ezilula ngala mathayela:

Isinyathelo 1: Hlanganisa nabo (Sum A)

  • Qala ngenombolo 1 (njengomthetho).
  • Engeza inombolo kusuka kuthayela ngalinye kulesi sibalo.

Isinyathelo 2: Gcina Ingqikithi Yokugijima Yazo Zonke Izimali (Sum B)

  • Ngaso sonke isikhathi lapho ungeza inombolo ye-tile entsha ku-Sum A, uphinde ungeze inani elisha le-Sum A ku-Sum B.
  • Kufana nokufumbathisa izinhlamvu zemali: ungeza uhlamvu lwemali olulodwa ngaphezulu (Sum A), bese ubhala phansi ukuphakama okusha okuphelele kwesitaki (Sum B).

Ekugcineni, unamathisela ingqikithi emibili ndawonye ukwenza inombolo eyodwa enkulu. Leyo nombolo enkulu yi-Adler-32 checksum.
