Isibali sekhodi ye-Hash esisebenzisa umsebenzi we-hash we-Secure Hash Algorithm 512/256 bit (SHA-512/256) ukuze kubalwe ikhodi ye-hash ngokusekelwe kokufakwa kombhalo noma ukulayishwa kwefayela.

Leli khasi lihunyushwe ngomshini lisuka esiNgisini ukuze lenze lifinyeleleke kubantu abaningi ngangokunokwenzeka. Ngeshwa, ukuhumusha ngomshini akukabi ubuchwepheshe obuphelele, ngakho-ke amaphutha angenzeka. Uma uthanda, ungabuka inguqulo yokuqala yesiNgisi lapha:

SHA-512/256 Hash Code Calculator

I-SHA-512/256 (i-Secure Hash Algorithm 512/256-bit) iwumsebenzi we-cryptographic hash othatha okokufaka (noma umlayezo) futhi ukhiqize umphumela ongusayizi ohleliwe, ongu-256-bit (32-byte), ovame ukumelwa njengenombolo ye-hexadecimal enezinhlamvu ezingu-64. Ingowomndeni we-SHA-2 wemisebenzi ye-hash, eklanywe yi-NSA. Ngempela iyi-SHA-512 enamanani ahlukene okuqalisa kanye nomphumela oncishisiwe ube yi-256 bits, ukuze kuzuze iqiniso lokuthi i-SHA-512 isebenza ngokushesha kune-SHA-256 kumakhompyutha angu-64 bit, kodwa ukuze kugcinwe izidingo ezincane zokugcina zamakhodi e-hash angu-256 bit.

Imiphumela ye-SHA-512, SHA-256 kanye ne-SHA-512/256 ihluke ngokuphelele kokufakwayo okufanayo, ngakho-ke ayihambisani - okungukuthi akunangqondo ukuqhathanisa ikhodi ye-hash ye-SHA-256 yefayela nekhodi ye-hash ye-SHA-512/256 yefayela elifanayo ukuze ubone 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.


Bala Ikhodi Ye-Hash Entsha

Idatha ethunyelwe noma amafayela alayishwe ngaleli fomu azogcinwa kuseva kuphela uma nje kuthatha ukukhiqiza ikhodi ye-hashi eceliwe. Izosuswa ngokushesha ngaphambi kokuthi umphumela ubuyiselwe esipheqululini sakho.

Idatha yokokufaka:



Umbhalo othunyelwe ubhalwe ngekhodi ye-UTF-8. Njengoba imisebenzi ye-hash isebenza kudatha kanambambili, umphumela uzohluka kunalapho umbhalo ubukomunye umbhalo wekhodi. Uma udinga ukubala i-hash yombhalo ekubhaleni ngekhodi okuthile, kufanele ulayishe ifayela esikhundleni salokho.



Mayelana ne-SHA-512/256 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 zazo ezifana ne-SHA-512:

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-512 ku-SHA-512).
  • 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

  • Ngokunqamula (ukusika) umphumela ube yi-256 bits, sisebenzisa iqiniso lokuthi i-SHA-512 isebenza ngokushesha kune-SHA-256 ezinhlelweni ze-64 bit, kodwa futhi sigcina izinzuzo zezidingo ezincane zokugcina amakhodi we-hash angu-256 bit. Qaphela ukuthi imiphumela ayihambisani, i-SHA-512/256 kanye ne-SHA-256 zikhiqiza amakhodi we-hash ahluke ngokuphelele.

Mina ngokwami ngivame ukunamathela ku-SHA-256, kodwa mhlawumbe lokho kumane kungumkhuba omdala engidinga ukuwulahla. Lapho ngiklama izinhlelo ezintsha ezizosebenza kakhulu (noma ngokuphelele) kumakhompyutha angu-64 bit, i-SHA-512/256 ibonakala iyisinqumo esingcono.
