Isibali sekhodi sehashi SHA-512

I-SHA-512 (i-Secure Hash Algorithm 512-bit) ngumsebenzi we-hash we-cryptographic othatha okokufaka (noma umyalezo) futhi ukhiqiza usayizi ohleliwe, ukukhishwa kwe-512-bit (64-byte), okuvame ukumelwa njengenombolo ye-hexadecimal yezinhlamvu ze-128. Kungokwalabo umndeni we-SHA-2 wemisebenzi ye-hash, eyenzelwe i-NSA futhi ngokuvamile esetshenziselwa izinhlelo zokusebenza lapho udinga ukuphepha okukhulu, njengedatha ebucayi kakhulu, ukugcinwa kwesikhathi eside, ukubethela kwebanga lempi, kanye nokuhlolwa kwesikhathi esizayo ngokumelene nezinsongo eziguqukayo, 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

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 ezintathu:

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.

Mina ngokwami ngicabangela umsebenzi ohlobene we-SHA-256 hash ovikelekile ngokwanele ngezinhloso zami, kodwa uma ufuna okuthile okungeziwe, i-SHA-512 ingaba yindlela yokuhamba. Ungathatha futhi umgwaqo ophakathi bese uhlola i-SHA-384: Isibali sekhodi sehashi SHA-384 ;-)

Ngenxa yendlela eyenzelwe ngayo, i-SHA-512 empeleni igijima ngokushesha kune-SHA-256 kumakhompyutha we-64 bit, okubandakanya ama-laptops amaningi namadeskithophu ngesikhathi sokubhala, kodwa kungenzeka kungafaki izinhlelo ezincane ezifakiwe. Ububi wukuthi ukugcina amakhodi we-SHA-512 hash kudinga amakhodi we-SHA-256 hash wesitoreji kabili.

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