Kwihlabathi lobugcisa kunye nokhuseleko lwekhompyuter, i Uguqulelo oluntsonkothileyo lwe-SHA Ibe sisixhobo esisisiseko sokuqinisekisa ubumfihlo kunye nesidima solwazi. Ngaphandle kokubaluleka kwayo, bambalwa abaziyo ukuba ngoobani abakrelekrele basemva kwale ndalo intsha. Ngubani, ngokwenene, ngumqambi we Uguqulelo oluntsonkothileyo lwe-SHA? Kweli nqaku, siza kuphonononga ubomi kunye nomsebenzi we-mastermind owaguqula umhlaba wokhuseleko lwekhompyuter nge-algorithm yakhe entsha.

-Inyathelo ngenyathelo ➡️ Ngubani umqambi we-algorithm yoguqulelo oluntsonkothileyo ye-SHA?

Ngubani umsunguli we-algorithm ye-SHA encryption?

  • I-algorithm ye-encryption ye-SHA, okanye i-Algorithm ekhuselekileyo ye-Hash, Ngomnye wemisebenzi ye-cryptographic esetyenziswa kakhulu kwihlabathi lokhuseleko lwekhompyuter.
  • Yasungulwa yi-United States National Security Agency (NSA) ngo-1993, njengempendulo kwimfuno ye-encryption algorithms ekhuselekileyo.
  • Uyilo lwe-algorithm lwenziwa yi-NSA ngokubambisana ne-Central Intelligence Agency (CIA). kunye nentsebenziswano yeengcali ze-cryptography.
  • Eyona njongo iphambili ye-algorithm ye-SHA kukuvelisa amaxabiso ehashi awodwa kwaye angaphindi aphindeke, ukuyenza ilungele izicelo ezifuna ukhuseleko oluphezulu kunye nokuthembeka ekuqinisekiseni ukuthembeka kwedatha.
  • I-algorithm ye-SHA iye yavela kwiminyaka, ngeenguqulelo ezininzi eziye zaphucula ukomelela kunye nokuchasa uhlaselo lwe-cryptographic olunokwenzeka.
