Isibali sekhodi sehashi Tiger-128/3

I-Tiger 128/3 (Tiger 128 bits, 3 rounds) iwumsebenzi we-cryptographic hashi othatha okokufaka (noma umlayezo) futhi ukhiqize usayizi ongashintshi, ophumayo ongu-128-bit (16-byte), ovame ukumelelwa njengenombolo ye-hexadecimal yezinhlamvu ezingu-32.

Umsebenzi we-Tiger hashi wumsebenzi we-cryptographic hashi owaklanywa uRoss Anderson no-Eli Biham ngo-1995. Wenzelwe ngokukhethekile ukusebenza ngokushesha ezisekelweni ze-64-bit, okuwenza ulungele izinhlelo zokusebenza ezidinga ukucutshungulwa kwedatha ngesivinini esikhulu, njengokuqinisekisa ubuqotho befayela, amasignesha edijithali, kanye nenkomba yedatha. Ikhiqiza amakhodi e-hashi angu-192 emizuliswaneni emi-3 noma emi-4, engancishiswa ibe ngamabhithi angu-160 noma angu-128 uma kudingeka ukuze kube nemingcele yokugcina noma ukuhambisana nezinye izinhlelo zokusebenza.

Ayisabhekwa njengevikelekile ezinhlelweni zokusebenza zesimanjemanje ze-cryptographic, kodwa ifakiwe lapha uma kwenzeka umuntu edinga ukubala ikhodi ye-hashi ukuze ahambisane nokuhlehla.

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-128/3 Hash Algorithm

Angisona isazi sezibalo noma umdwebi we-cryptographer, kodwa ngizozama ukuchaza lo msebenzi we-hash ngokwemibandela ye-layman ngesibonelo. Uma ukhetha incazelo enembile ngokwesayensi nenemba ngokugcwele yezibalo, ngiyaqiniseka ukuthi ungathola lokho kwamanye amawebhusayithi amaningi ;-)

Manje, zicabange wenza iresiphi eyimfihlo ye-smoothie. Uphonsa izithelo eziningi (idatha yakho), uyihlanganise ngendlela ekhethekile (inqubo ye-hashing), futhi ekugcineni, uthola ukunambitheka okuyingqayizivele (i-hashi). Ngisho noma ushintsha into eyodwa nje encane - njengokwengeza i-blueberry eyodwa - ukunambitheka kuzohluka ngokuphelele.

Nge-Tiger, kunezinyathelo ezintathu kulokhu:

Isinyathelo 1: Ukulungiselela Izithako (Ukuphehla Idatha)

• Kungakhathaliseki ukuthi inkulu noma incane kangakanani idatha yakho, i-Tiger iqinisekisa ukuthi ingusayizi ofanele we-blender. Yengeza i-filler eyengeziwe eyengeziwe (njenge-padding) ukuze yonke into ilingane kahle.

Isinyathelo sesi-2: I-Super Blender (Umsebenzi Wokucindezela)

• Le blender inama-blade amathathu anamandla.
• Idatha inqunywa ibe yizingcezu, futhi i-chunk ngayinye idlula ku-blender eyodwa ngesikhathi.
• Ama-blade awagcini nje ukuphenduka - ayaxuba, aphihlize, asonte, futhi axazulule idatha ngezindlela ezingasile kusetshenziswa amaphethini akhethekile (lawa afana nezilungiselelo ze-blender eziyimfihlo eziqinisekisa ukuthi yonke into ixutshwa ngokungalindelekile).

Isinyathelo sesi-3: Ukuhlanganisa Okuningi (Ukudlula/Imijikelezo)

• Nakhu lapho kuba nentshisekelo khona. Ingwe ayigcini nje ngokuhlanganisa idatha yakho kanye - iyihlanganisa izikhathi eziningi ukuze iqinisekise ukuthi akekho ongathola izithako zokuqala.
• Lona umehluko phakathi kwezinguqulo eziyindilinga ezi-3 nezi-4. Ngokungeza umjikelezo owengeziwe wokuhlanganisa, izinguqulo eziyindilinga ezi-4 zivikeleke kancane, kodwa futhi azisheshi ukubala.
