Isibali sekhodi sehashi SHA-224

I-SHA-224 (i-Secure Hash Algorithm 224-bit) iwumsebenzi we-cryptographic hash othatha okokufaka (noma umlayezo) futhi ukhiqize umphumela ongusayizi ohleliwe, ongu-224-bit (28-byte), ovame ukumelwa njengenombolo ye-hexadecimal enezinhlamvu ezingu-56. Ingowomndeni we-SHA-2 wemisebenzi ye-hash, eklanywe yi-NSA. Empeleni iyinguqulo encishisiwe ye-SHA-256 enamanani ahlukene okuqalisa, ehloselwe izimo zokusetshenziswa lapho isivinini nokusebenza kahle kwesikhala kubaluleke kakhulu kunokuphepha okuphezulu, isibonelo izinhlelo ezifakiwe. I-SHA-224 isabhekwa njengephephile, noma kunjalo, incane kancane kune-SHA-256.

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-224 Hash Algorithm

Angiyena umuntu omuhle kakhulu ezibalweni futhi angizibheki njengososayensi wezibalo, ngakho-ke ngizozama ukuchaza lo msebenzi we-hash ngendlela abanye ochwepheshe bezibalo abangayiqonda. Uma ukhetha inguqulo yezibalo efanele ngokwesayensi, ngiyaqiniseka ukuthi ungayithola kwamanye amawebhusayithi amaningi ;-)

Nokho, ake sithi umsebenzi we-hash uyi-blender yobuchwepheshe obuphezulu eyenzelwe ukudala i-smoothie eyingqayizivele kusuka kunoma yiziphi izithako ozifaka kuyo. Lokhu kuthatha izinyathelo ezine, ezintathu zokuqala zazo ezifana ne-SHA-256:

Isinyathelo 1: Faka Izithako (Okufakwayo)

• Cabanga ngalokho okufakwayo njengento ofuna ukuyihlanganisa: ubhanana, ama-strawberry, izingcezu ze-pizza, noma ngisho nencwadi yonke. Akunandaba ukuthi ufaka ini - enkulu noma encane, elula noma eyinkimbinkimbi.

Isinyathelo 2: Inqubo Yokuhlanganisa (Umsebenzi we-Hash)

• Ucindezela inkinobho, bese i-blender iphenduka ngendlela exakile - iyasika, ixube, ijikeleze ngesivinini esikhulu. Ineresiphi ekhethekile ngaphakathi okungekho muntu ongayishintsha.
• Le recipe ifaka imithetho exakile efana nalokhu: "Jikela kwesobunxele, jika kwesokudla, jika ubheke phansi, shukumisa, nquma ngezindlela ezingavamile." Konke lokhu kwenzeka ngemuva kwezigcawu.

Isinyathelo 3: Uthola i-Smoothie (Okukhiphayo):

• Kungakhathaliseki ukuthi usebenzise izithako zini, i-blender ikunikeza njalo inkomishi eyodwa ye-smoothie (leyo usayizi ohleliwe wama-bits angu-256 ku-SHA-256).
• I-smoothie inokunambitheka okuhlukile nombala ngokusekelwe ezithakweni ozifakile. Ngisho noma ungashintsha into eyodwa encane - njengokufaka uhlamvu olulodwa lukashukela - i-smoothie izonambitheka ngendlela ehlukile ngokuphelele.

Isinyathelo 4: Nciphisa

• Umphumela wokugcina uyancishiswa (unqunywe) ube ama-bits angu-224, kulahla ama-bits angu-32 asele. Lokhu kwenza kube lula kakhulu isikhala, kodwa futhi kungavikeleki kangako. Kusasebenza kahle ekuhlolweni kobuqotho bamafayela nokunye okunjalo, kodwa ekusayinweni kwezitifiketi zedijithali kanye nezinye izimo zokusetshenziswa lapho ukuphepha kubalulekile khona, i-SHA-256 ingcono.
