Tiger-160/4 Hash Code Kalkuleta

Tiger 160/4 (Tiger 160 bits, 4 rounds) shine aikin hash na sirri wanda ke ɗaukar shigarwa (ko saƙo) kuma yana samar da ƙayyadaddun girma, fitarwa 160-bit (20-byte), yawanci ana wakilta azaman lambar hexadecimal mai haruffa 40.

Aikin hash na Tiger shine aikin hash na cryptographic wanda Ross Anderson da Eli Biham suka tsara a cikin 1995. An inganta shi musamman don yin aiki da sauri a kan dandamali na 64-bit, yana sa ya dace da aikace-aikacen da ke buƙatar sarrafa bayanai mai sauri, kamar tabbatar da amincin fayil, sa hannu na dijital, da ƙididdigar bayanai. Yana samar da lambobin zanta guda 192 a cikin zagaye 3 ko 4, waɗanda za a iya yanke su zuwa ko dai 160 ko 128 ragowa idan an buƙata don ƙuntatawar ajiya ko dacewa da wasu aikace-aikace.

Ba a sake ɗaukar shi amintacce don aikace-aikacen sirri na zamani, amma an haɗa shi anan idan mutum yana buƙatar ƙididdige lambar zanta don dacewa ta baya.

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 Tiger-160/4 Hash Algorithm

Ba ni ba masanin lissafi ba ne ko kuma mai yin cryptographer, amma zan yi ƙoƙarin bayyana wannan aikin hash a cikin sharuddan layman tare da misali. Idan kun fi son ingantaccen ilimin kimiyya kuma cikakken cikakken bayani akan lissafi mai nauyi, na tabbata zaku iya samun hakan akan yawancin sauran gidajen yanar gizo ;-)

Yanzu, yi tunanin kana yin girke-girke mai santsi a asirce. Kuna jefa 'ya'yan itatuwa masu yawa (bayanan ku), ku haɗa su ta hanya ta musamman (tsarin hashing), kuma a ƙarshe, kuna samun dandano na musamman (zanta). Ko da kun canza ƙaramin abu ɗaya kawai - kamar ƙara ƙarin blueberry guda ɗaya - dandano zai bambanta.

Tare da Tiger, akwai matakai uku zuwa wannan:

Mataki 1: Shirya Sinadaran (Padding the Data)

• Komai girman ko ƙanƙantar bayanan ku, Tiger yana tabbatar da girman girman da aka yi da blender. Yana ƙara ɗan ƙarin filler (kamar padding) don haka komai yayi daidai.

Mataki 2: Super Blender (Aikin matsawa)

• Wannan blender yana da ruwan wukake masu ƙarfi guda uku.
• Ana yayyanka bayanan a cikin gungu, kuma kowane yanki yana wucewa ta hanyar blender daya bayan daya.
• Wuraren ba wai kawai suna jujjuya ba - suna haɗawa, fasa, murɗawa, da kuma karkatar da bayanan ta hanyoyi masu hauka ta amfani da alamu na musamman (waɗannan suna kama da saitunan blender na sirri waɗanda ke tabbatar da cewa komai ya gauraye ba tare da annabta ba).

Mataki na 3: Haɗuwa da yawa (Masu wucewa/Zagaye)

• Anan ya zama mai ban sha'awa. Tiger ba wai kawai yana haɗa bayanan ku sau ɗaya ba - yana haɗa shi sau da yawa don tabbatar da cewa babu wanda zai iya gano ainihin abubuwan da suka dace.
• Wannan shine bambanci tsakanin nau'ikan zagaye na 3 da 4. Ta ƙara ƙarin sake zagayowar haɗawa, nau'ikan zagaye 4 sun ɗan fi aminci, amma kuma a hankali don ƙididdige su.
