Isibali sekhodi ye-Hash esisebenzisa umsebenzi we-hash we-Secure Hash Algorithm 3 384 bit (SHA3-384) 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:

I-SHA3-384 (i-Secure Hash Algorithm 3 384-bit) umsebenzi we-cryptographic hash othatha okokufaka (noma umlayezo) bese ukhiqiza umphumela ongusayizi ohleliwe, ongu-384-bit (48-byte), ovame ukumelwa njengenombolo ye-hexadecimal enezinhlamvu ezingu-96.

I-SHA-3 iyilungu lakamuva lomndeni we-Secure Hash Algorithm (SHA), eyakhishwa ngokusemthethweni ngo-2015. Ngokungafani ne-SHA-1 ne-SHA-2, ezisekelwe ezakhiweni ezifanayo zezibalo, i-SHA-3 yakhelwe kumklamo ohlukile ngokuphelele obizwa ngokuthi i-Keccak algorithm. Ayidalwanga ngoba i-SHA-2 ayivikelekile; i-SHA-2 isabhekwa njengephephile, kodwa i-SHA-3 ingeza ungqimba olwengeziwe lokuphepha ngomklamo ohlukile, uma kwenzeka ubuthakathaka besikhathi esizayo butholakala ku-SHA-2.

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-SHA3-384 Hash Algorithm

Angisiye isazi sezibalo noma isazi se-cryptographer, ngakho-ke ngizozama ukuchaza lo msebenzi we-hash ngendlela abanye ochwepheshe bezibalo abangayiqonda. Uma ukhetha incazelo yezibalo enembile ngokwesayensi, ungayithola kumawebhusayithi amaningi ;-)

Nokho, ngokungafani nemindeni ye-SHA yangaphambilini (SHA-1 kanye ne-SHA-2), engabhekwa njenge-blender, i-SHA-3 isebenza njengesiponji.

Inqubo yokubala i-hash ngale ndlela ingahlukaniswa ngezinyathelo ezintathu ezisezingeni eliphezulu:

Isinyathelo 1 - Isigaba Sokumunca

  • Cabanga uthela amanzi (idatha yakho) esipontshini. Isipontshi simunca amanzi kancane kancane.
  • Ku-SHA-3, idatha yokufaka ihlukaniswa ibe yizicucu ezincane bese imuncwa "kwisiponji" sangaphakathi (uhlu olukhulu lwe-bit).

Isinyathelo 2 - Ukuxuba (Ukuguqulwa)

  • Ngemva kokudonsa idatha, i-SHA-3 iyacindezela futhi iphendule isiponji ngaphakathi, ixube konke okuzungezile ngamaphethini ayinkimbinkimbi. Lokhu kuqinisekisa ukuthi ngisho noshintsho oluncane kokufakwayo luphumela ku-hash ehluke ngokuphelele.

Isinyathelo 3 - Isigaba Sokucindezela

  • Ekugcineni, ucindezela isiponji ukuze ukhulule umphumela (i-hash). Uma udinga i-hash ende, ungaqhubeka ucindezela ukuze uthole umphumela owengeziwe.

Ngenkathi isizukulwane se-SHA-2 semisebenzi ye-hash sisabhekwa njengesiphephile (ngokungafani ne-SHA-1, okungafanele isetshenziselwe ukuphepha), kungaba nengqondo ukuqala ukusebenzisa isizukulwane se-SHA-3 esikhundleni salokho lapho uklama izinhlelo ezintsha, ngaphandle kokuthi zidinga ukuhambisana nezinhlelo ezindala ezingazisekeli.

Into eyodwa okufanele uyicabangele ukuthi isizukulwane se-SHA-2 cishe siwumsebenzi we-hash osetshenziswa kakhulu futhi ohlaselwa kakhulu kunayo yonke (ikakhulukazi i-SHA-256 ngenxa yokusetshenziswa kwayo ku-blockchain ye-Bitcoin), kodwa isasebenza. Kuzoba isikhathi eside ngaphambi kokuba i-SHA-3 imelane nokuhlolwa okufanayo okunzima ngezigidigidi.
