Isibali sekhodi sehashi Tiger-160/3

I-Tiger 160/3 (Tiger 160 bits, 3 rounds) umsebenzi we-cryptographic hash othatha okokufaka (noma umlayezo) futhi ukhiqize umphumela ongusayizi ohleliwe, ongu-160-bit (20-byte), ovame ukumelwa njengenombolo ye-hexadecimal enezinhlamvu ezingu-40.

Umsebenzi we-Tiger hash uwumsebenzi we-cryptographic hash owaklanywa nguRoss Anderson no-Eli Biham ngo-1995. Wawulungiselelwe ngqo ukusebenza okusheshayo kumapulatifomu angu-64-bit, okwenza ufaneleke kahle izinhlelo zokusebenza ezidinga ukucutshungulwa kwedatha okusheshayo, njengokuqinisekiswa kobuqotho bamafayela, ukusayina kwedijithali, kanye nokukhonjwa kwedatha. Ukhiqiza amakhodi e-hash angu-192 bit emizuliswaneni engu-3 noma engu-4, angancishiswa abe yi-160 noma i-128 bit uma kudingeka ngenxa yemikhawulo yokugcina noma ukuhambisana nezinye izinhlelo zokusebenza.

Akusabhekwa njengokuphephile kwezinhlelo zokusebenza zesimanje ze-cryptographic, kodwa kufakiwe lapha uma umuntu edinga ukubala ikhodi ye-hash yokuhambisana nokubuyela emuva.

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-Tiger-160/3 Hash Algorithm

Angisiye isazi sezibalo noma isazi se-cryptographer, kodwa ngizozama ukuchaza lo msebenzi we-hash ngokwesimo se-layman ngesibonelo. Uma ukhetha incazelo egcwele yezibalo enembile ngokwesayensi, ngiyaqiniseka ukuthi ungakuthola lokho kwamanye amawebhusayithi amaningi ;-)

Manje, ake ucabange wenza iresiphi eyimfihlo ye-smoothie. Ufaka inqwaba yezithelo (idatha yakho), uyixube ngendlela ekhethekile (inqubo ye-hashing), bese ekugcineni, uthola ukunambitheka okuhlukile (i-hash). Ngisho noma ushintsha into eyodwa encane - njengokwengeza i-blueberry eyodwa - ukunambitheka kuzohluka ngokuphelele.

NgeTiger, kunezinyathelo ezintathu kulokhu:

Isinyathelo 1: Ukulungiselela Izithako (Ukugcwalisa Idatha)

• Kungakhathaliseki ukuthi idatha yakho inkulu noma incane kangakanani, iTiger iyaqinisekisa ukuthi iyisayizi efanele ye-blender. Ingeza i-filler encane eyengeziwe (njenge-padding) ukuze konke kulingane kahle.

Isinyathelo 2: I-Super Blender (Umsebenzi Wokucindezela)

• Le blender inama-blade amathathu anamandla.
• Idatha inqunywa ibe yizicucu, futhi isicucu ngasinye sidlula ku-blender ngasinye ngesikhathi.
• Ama-blade awagcini nje ngokuphotha - axuba, aphule, asonte, futhi axove idatha ngezindlela ezixakile esebenzisa amaphethini akhethekile (lokhu kufana nezilungiselelo ze-blender eziyimfihlo eziqinisekisa ukuthi konke kuhlanganiswa ngendlela engalindelekile).

Isinyathelo 3: Ukuxubana Okuningana (Amaphasi/Ama-Round)

• Nakhu lapho kuba mnandi khona. I-Tiger ayihlanganisi idatha yakho kanye kuphela - iyihlanganisa kaningi ukuqinisekisa ukuthi akekho ongathola izithako zokuqala.
• Lona umehluko phakathi kwezinguqulo ezi-3 nezi-4 eziyindilinga. Ngokufaka umjikelezo owengeziwe wokuxuba, izinguqulo ezi-4 eziyindilinga ziphephile kancane, kodwa futhi zihamba kancane ukubala.
