Konke malunga ne-hashing 

Kwihlabathi lanamhlanje ledijithali, ukhuseleko lwedatha luyinkxalabo enkulu kubantu kunye nemibutho. Ukusuka ekukhuselweni kwegama eliyimfihlo ukuya kwimfezeko yedatha, kubalulekile ukuba kubekho iindlela ezomeleleyo zokuqinisekisa ubumfihlo kunye nokunyaniseka kolwazi olubuthathaka. Kulapho i-hashing ingena khona.

I-Hashing, ubuchule be-cryptographic esisiseko, inikeza a ukulungisa okunamandla ukukhusela idatha ngokungenakujikwa.

Kweli nqaku, siza kuntywila kwiinkcukacha ze-hashing, siphonononge indlela esebenza ngayo, ukusetyenziswa kwayo, kunye nokufaneleka kwayo kukhuseleko lwe-IT.

🚀 Yintoni ihashi? 

I-Hashing, ngamagama alula, lutshintsho lwemathematika oluthatha idatha yesayizi eguquguqukayo kwaye iyiguqule ibe yiminwe yedijithali ekhethekileyo yobukhulu obusisigxina. Lo mbhalo, uhlala ubizwa ngokuba "hashi", yi-cryptographic digest eshwankathela yonke idatha yoqobo engenakuguqulwa.

Ngamanye amazwi, akunakwenzeka ukwenza kwakhona idatha yoqobo ukusuka kwi-hash, ukwenza i-hashing ibaluleke indlela enye yokuqinisekisa ubumfihlo kunye nemfezeko yolwazi. 

Enye yezona zinto ziqhelekileyo zokusetyenziswa kwe-hashing yi idatha yokujonga ingqibelelos. Ngokubala umnwe wefayile okanye isethi yedatha, kunokwenzeka ukuba ufumane naluphi na utshintsho okanye ukuguqulwa kwedatha.

Kwanotshintsho oluncinci kwidatha yoqobo luya kubangela umnwe ohluke ngokupheleleyo, okwenza kube lula ukuchonga iimpazamo okanye ukuzama ukukhohlisa ngokukhawuleza. 

I-hash iphinda ifumane indawo yayo kwintsimi ye-cryptography, inikezela a ukhuseleko oluqinileyo lokugqitha kunye nolwazi olubuthathaka. Kunokuba ugcine amagama ayimfihlo ngqo kuvimba weenkcukacha, iinkqubo ezikhuselekileyo ziwagcine phambi kokuba uwagcine.
