Isibali sekhodi sehashi Whirlpool

Umsebenzi we-hash we-Whirlpool uwumsebenzi we-hash we-cryptographic owaklanywa nguVincent Rijmen (omunye wabaklami be-AES) noPaulo SLM Barreto. Wethulwa okokuqala ngo-2000 futhi kamuva wabuyekezwa ngo-2003 ukuze kuthuthukiswe ukuphepha. I-Whirlpool iyingxenye yendinganiso ye-ISO/IEC 10118-3, okwenza ifaneleke ezinhlelweni eziningi ze-cryptographic. Ikhiqiza ikhodi ye-hash engu-512 bit (64 byte), evame ukumelwa njengezinhlamvu ezingu-128 ze-hexadecimal.

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-Algorithm ye-Whirlpool Hash

Angisiye isazi sezibalo noma isazi se-cryptographer, ngakho-ke ngizozama ukuchaza ukuthi lo msebenzi we-hash usebenza kanjani ngokwemigomo yabantu abavamile. Uma ukhetha incazelo enembile ngokwesayensi, enzima yezibalo, ngiyaqiniseka ukuthi ungakuthola lokho kwamanye amawebhusayithi ;-)

Nokho, ake sithi wenza i-smoothie enezithako eziningi: ubhanana, ama-strawberry, isipinashi, ibhotela lamantongomane, njll. Nakhu okwenziwa yi-Whirlpool ezithakweni zakho (noma idatha):

Isinyathelo 1 - Sika Konke (Ukuhlukanisa Idatha Ibe Yizicucu)

• Okokuqala, ihlukanisa idatha yakho ibe yizicucu ezincane, njengokusika izithelo ngaphambi kokuxuba.

Isinyathelo 2 - Hlanganisa Njengokuhlanya (Ukuxuba)

Manje, ifaka lezi zingcezu ku-blender enamandla enezivinini eziyi-10 ezahlukene (ezibizwa ngokuthi "ama-round"). Umjikelezo ngamunye uxuba idatha ngendlela ehlukile:

• Shintsha bese Ushintsha (Ukufaka esikhundleni): Ezinye izingcezu zishintshwa zibe ezinye, njengokushintsha i-strawberry ne-blueberry.
• Hlanganisa Izindilinga (Ukuguqulwa): Ijikeleza ingxube, ishintsha izithako ukusuka kwenye indawo iye kwenye ukuze kungabikho lutho oluhlala endaweni yalo yokuqala.
• Hlanganisa Konke Kube Kanye (Ukuxuba): Kuphula futhi kuvuselele ukuze kusakazwe ukunambitheka (noma idatha) ngokulinganayo kuyo yonke ingxube.
• Engeza Isithako Esiyimfihlo (Ukuxuba Okuyisihluthulelo): Sifafaza "isithako esiyimfihlo" (ikhodi ekhethekile) ukuze senze i-smoothie ibe yehlukile.

Isinyathelo 3 - Umphumela Wokugcina (I-Hash)

• Ngemva kwemijikelezo eyi-10 yokuxuba okunamandla, uthola isiphuzo esibushelelezi nesixubene kahle - noma kulokhu, i-hash engu-512-bit. Akusekho ndlela yokukhipha ubhanana noma isipinashi sokuqala ku-smoothie. Okusele nje isiphuzo sokugcina.

Ukufunda Okuqhubekayo

Uma ukujabulele lokhu okuthunyelwe, ungaphinda uthande lezi ziphakamiso:
