Kalkuleta na lambar hash RIPEMD-320

RIPEMD-320 aiki ne na hash na sirri wanda ke ɗaukar shigarwa (ko saƙo) kuma yana samar da fitarwa mai girman bit 320 (byte 40), wanda aka fi wakilta a matsayin lambar hexadecimal mai haruffa 80.

RIPEMD (RACE Integrity Primitives Evaluation Message Digest) wani iyali ne na ayyukan hash na ɓoye bayanai waɗanda aka tsara don samar da sahihancin bayanai ta hanyar hashing. An ƙirƙiro shi a tsakiyar shekarun 1990 a matsayin wani ɓangare na aikin RACE (Bincike da Ci Gaba a Fasahar Sadarwa ta Ci Gaba a Turai) na EU.

Har yanzu ana ɗaukar RIPEMD a matsayin amintacce, sai dai sigar bit 128, wacce ke fuskantar irin wannan damuwa kamar MD4 da MD5.

Cikakken bayyanawa: Ban rubuta takamaiman aiwatar da aikin hash da aka yi amfani da shi akan wannan shafin ba. Daidaitaccen aiki ne wanda aka haɗa tare da yaren shirye-shiryen PHP. Na yi mahaɗin yanar gizo ne kawai don sanya shi a fili a nan don dacewa.

Game da Tsarin Hash na RIPEMD-320

Ni ba masanin lissafi ba ne kuma ba masanin fasahar ɓoye bayanai ba ne, amma zan yi ƙoƙarin bayyana yadda wannan aikin hash yake aiki ta yadda waɗanda ba masu lissafi ba za su iya fahimta. Idan ka fi son cikakken bayanin lissafi na kimiyya, ina da tabbacin za ka iya samun hakan a wasu gidajen yanar gizo da yawa ;-)

RIPEMD tana amfani da tsarin Merkle-Damgård, wanda wani abu ne da yake kama da dangin SHA-2 na algorithms na hash. Na bayyana waɗanda ke aiki kamar na'urar haɗawa a wasu shafuka, kuma haka yake ga RIPEMD:

Mataki na 1 - Shiri (Kulle Bayanan)

• Da farko, RIPEMD yana tabbatar da cewa "sinadaran" sun dace daidai a cikin blender. Idan ba haka ba, yana ƙara ƙarin "ciller" don kammala shi (wannan kamar cika bayanai ne).

Mataki na 2 - Fara Blender (Fara aiki)

• Na'urar haƙa ta fara da takamaiman saiti - kamar gudu, ƙarfi, da matsayin ruwan wuka. Waɗannan su ne ƙimar farawa ta musamman da ake kira vectors na farawa.

Mataki na 3 - Tsarin Haɗawa (Runƙushe Bayanan)

• Ga abin sha'awa: RIPEMD ba wai kawai yana da ruwan wukake ɗaya ba. Yana da injin haɗa abubuwa guda biyu da ke aiki gefe da gefe (hagu da dama).
• Kowace na'urar hadawa tana sarrafa sinadaran ta hanyoyi daban-daban. Ɗaya yana yankawa yayin da ɗayan kuma yana niƙawa, ta amfani da hanyoyi daban-daban, kwatance, da kuma tsarin ruwan wukake.
• Suna gauraya, musanya, da kuma karkatar da bayanai sau 80 (kamar haɗawa a cikin zagayowar don tabbatar da cewa komai ya haɗu sosai).

Mataki na 4 - Haɗakar Ƙarshe (Haɗa Sakamako)

• Bayan duk wannan haɗuwa, RIPEMD yana haɗa sakamakon daga duka na'urorin haɗa guda biyu zuwa hash na ƙarshe mai santsi.
