Isibali sekhodi ye-hash esisebenzisa umsebenzi we-hash we-RACE Integrity Primitives Evaluation Message Digest 320 bit (RIPEMD-320) ukuze kubalwe ikhodi ye-hash ngokusekelwe kokufakwa kombhalo noma ukulayishwa kwefayela.

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:

RIPEMD-320 Hash Code Calculator

I-RIPEMD-320 umsebenzi we-cryptographic hash othatha okokufaka (noma umlayezo) bese ukhiqiza umphumela ongusayizi ohleliwe, ongu-320-bit (40-byte), ovame ukumelwa njengenombolo ye-hexadecimal enezinhlamvu ezingu-80.

I-RIPEMD (RACE Integrity Primitives Evaluation Message Digest) umndeni wemisebenzi ye-cryptographic hash eyenzelwe ukunikeza ubuqotho bedatha nge-hashing. Yasungulwa maphakathi nawo-1990 njengengxenye yephrojekthi ye-EU ye-RACE (Research and Development in Advanced Communications Technologies in Europe).

I-RIPEMD isabhekwa njengephephile, ngaphandle kwenguqulo ye-128 bit, ebhekene nezinkinga ezifanayo ne-MD4 kanye ne-MD5.

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-RIPEMD-320 Hash Algorithm

Angisiye isazi sezibalo noma isazi se-cryptographer, kodwa ngizozama ukuchaza ukuthi lo msebenzi we-hash usebenza kanjani ngendlela abangebona ochwepheshe bezibalo abangayiqonda. Uma ukhetha incazelo yezibalo egcwele ngokwesayensi esikhundleni salokho, ngiyaqiniseka ukuthi ungakuthola lokho kwamanye amawebhusayithi amaningi ;-)

I-RIPEMD isebenzisa ukwakhiwa kwe-Merkle-Damgård, okuyinto efana ngayo nomndeni we-SHA-2 wama-algorithms e-hash. Ngichaze lawo njengasebenza ngendlela efanayo ne-blender kwamanye amakhasi, futhi okufanayo kuyiqiniso nge-RIPEMD:

Isinyathelo 1 - Ukulungiselela (Ukugcwalisa Idatha)

Okokuqala, i-RIPEMD iqinisekisa ukuthi "izithako" zilingana kahle ku-blender. Uma kungenjalo, ingeza "i-filler" eyengeziwe ukuze iyigcwalise (lokhu kufana nokugcwalisa idatha).

Isinyathelo 2 - Ukuqala i-Blender (Ukuqalisa)

I-blender iqala ngesethingi ethile - njengejubane, amandla, kanye nendawo ye-blade. Lawa amanani okuqala akhethekile abizwa ngokuthi ama-initialization vectors.

Isinyathelo 3 - Inqubo Yokuxuba (Ukunquma Idatha)

Nansi ingxenye epholile: I-RIPEMD ayinayo nje isethi eyodwa yama-blade. Inama-blender amabili asebenza eceleni (kwesobunxele nakwesokudla).
I-blender ngayinye icubungula izithako ngendlela ehlukile. Enye iyaqoba kanti enye iyagaya, isebenzisa isivinini esihlukile, iziqondiso, kanye namaphethini ama-blade.
Bayaxuba, bashintshanise, futhi basonte idatha izikhathi ezingu-80 (njengokuxuba imijikelezo ukuqinisekisa ukuthi konke kuxubene kahle).

Isinyathelo 4 - Ukuhlanganiswa Kokugcina (Ukuhlanganisa Imiphumela)

Ngemva kwakho konke lokho kuxuba, i-RIPEMD ihlanganisa imiphumela evela kuzo zombili izihlanganisi ibe yi-hash eyodwa yokugcina, ebushelelezi.
