Isibali sekhodi sehashi SHA-512

I-SHA-512 (i-Secure Hash Algorithm 512-bit) iwumsebenzi we-cryptographic hash othatha okokufaka (noma umlayezo) futhi ukhiqize umphumela ongusayizi ohleliwe, ongu-512-bit (64-byte), ovame ukumelwa njengenombolo ye-hexadecimal enezinhlamvu ezingu-128. Ingowomndeni we-SHA-2 wemisebenzi ye-hash, eklanywe yi-NSA futhi evame ukusetshenziselwa izinhlelo zokusebenza lapho udinga khona ukuphepha okuphezulu, njengedatha ebucayi kakhulu, ukugcinwa kwemininingwane kwesikhathi eside, ukubethela kwebanga lezempi, kanye nokuqinisekiswa kwesikhathi esizayo ngokumelene nezinsongo ezishintshayo, njenge-quantum computing.

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 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 ezintathu:

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.

Mina ngokwami ngibheka umsebenzi we-hash we-SHA-256 ohlobene uvikelekile ngokwanele ngezinjongo zami, kodwa uma ufuna okuthile okwengeziwe, i-SHA-512 ingaba yindlela okufanele uyenze. Ungathatha futhi indlela ephakathi bese uhlola i-SHA-384: Isixhumanisi ;-)

Ngenxa yendlela eklanywe ngayo, i-SHA-512 empeleni isebenza ngokushesha kune-SHA-256 kumakhompyutha angu-64 bit, okuhlanganisa ama-laptop amaningi nama-desktop ngesikhathi sokubhala, kodwa kungase kungabi nezinhlelo ezincane ezifakiwe. Ububi ukuthi ukugcina amakhodi e-hash e-SHA-512 kudinga amakhodi e-hash e-SHA-256 aphindwe kabili kunesitoreji.

Njengoba kwenzeka, abanye abantu abahlakaniphile baqhamuka nendlela yokuthola okungcono kakhulu kokubili, okungukuthi umsebenzi we-SHA-512/256 hash: Isixhumanisi
