Isibali sekhodi sehashi SHA-512/224

I-SHA-512 / 224 (i-Secure Hash Algorithm 512 / 224-bit) ngumsebenzi we-hash we-cryptographic othatha okokufaka (noma umyalezo) futhi ukhiqiza ukukhishwa kwe-fixed-size, i-224-bit (28-byte), evame ukumelwa njengenombolo ye-hexadecimal yezinhlamvu ze-56. Kungokwalabo umndeni SHA-2 imisebenzi hash, yakhelwe NSA. Kuyinto ngempela SHA-512 nge ezahlukene ukuqaliswa amanani kanye nomphumela wanqamula 224 bits, ukusizakala iqiniso lokuthi SHA-512 ugijima ngokushesha kuka SHA-256 (okuyinto SHA-224 inguqulo enqunyiwe of) kumakhompyutha 64 bit, kodwa ukugcina izidingo isitoreji ezincane 224 bit hash amakhodi.

Imiphumela ye-SHA-512, i-SHA-224 ne-SHA-512 / 224 ihluke ngokuphelele ekufakeni okufanayo, ngakho-ke ayihambisani - okusho ukuthi akunangqondo ukuqhathanisa ikhodi ye-SHA-224 hash yefayela nekhodi ye-SHA-512 / 224 hash yefayela elifanayo ukubona ukuthi ishintshiwe yini.

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-SHA-512 / 224 Hash Algorithm

Angilungile ngokukhethekile kwizibalo futhi angizithathi neze njengesazi sezibalo, ngakho-ke ngizozama ukuchaza lo msebenzi we-hash ngendlela yokuthi abanye bami abangewona izazi zezibalo bangaqonda. Uma ukhetha i-math-version efanele ngokwesayensi, ngiyaqiniseka ukuthi ungathola lokho kwamanye amawebhusayithi amaningi ;-)

Nakanjani, ake sicabange ukuthi umsebenzi we-hash uyi-super high-tech blender eyenzelwe ukudala i-smoothie eyingqayizivele kunoma yiziphi izithako ozifaka kuyo. Lokhu kuthatha izinyathelo ezine, ezintathu zazo zifana ne-SHA-512:

Isinyathelo 1: Faka Izithako (Ukufaka)

• Cabanga ngokufaka njenganoma yini ofuna ukuyihlanganisa: ubhanana, ama-strawberry, izingcezu ze-pizza, noma ngisho nencwadi yonke. Akunandaba ukuthi yini oyifakayo - enkulu noma encane, elula noma eyinkimbinkimbi.

Isinyathelo 2: Inqubo Yokuxuba (Umsebenzi we-Hash)

• Ucindezela inkinobho, futhi blender uya zasendle - ukusika, ukuxuba, ukuphotha ngesivinini crazy. It has a iresiphi ekhethekile ngaphakathi ukuthi akekho ongashintsha.
• Leresiphi kuhlanganisa imithetho crazy like: "Spin kwesokunxele, spin kwesokudla, flip ebheke phansi, shake, chop ngezindlela ezingavamile." Konke lokhu kwenzeka ngemuva.

Isinyathelo 3: Uthola i-Smoothie (Okukhiphayo):

• Kungakhathaliseki ukuthi yiziphi izithako ozisebenzise, i-blender ihlala ikunika ncamashi inkomishi eyodwa ye-smoothie (lokho usayizi ohleliwe we-512 bits ku-SHA-512).
• I-smoothie inokunambitheka okuyingqayizivele nombala ngokusekelwe kwizithako ozifakayo. Ngisho noma ushintsha nje into eyodwa encane - njengokungeza okusanhlamvu okukodwa koshukela - i-smoothie izonambitheka ihluke ngokuphelele.

Isinyathelo 4: Truncate

• Ngokunqamula (ukusika) umphumela phansi ku-224 bits, sisebenzisa iqiniso lokuthi i-SHA-512 igijima ngokushesha kune-SHA-224 ezinhlelweni ze-64 bit, kodwa futhi igcine inzuzo yezidingo ezincane zokugcina amakhodi we-224 bit hash. Qaphetha ukuthi imiphumela ayihambisani, i-SHA-512 / 224 ne-SHA-224 ikhiqiza amakhodi we-hash ahluke ngokuphelele.
