Konke mayelana ne-hashing 

Emhlabeni wanamuhla wedijithali, ukuphepha kwedatha kuyinkinga enkulu kubantu ngabanye nezinhlangano. Ukusuka ekuvikelweni kwephasiwedi kuye ekuthembekeni kwedatha, kubalulekile ukuthi kube nezinqubo eziqinile zokuqinisekisa ukugcinwa kuyimfihlo kanye nobuqiniso bolwazi olubucayi. Yilapho i-hashing ingena khona.

I-Hashing, indlela eyisisekelo ye-cryptographic, inikeza a ukulungisa okunamandla ukuze uvikele idatha ngendlela engenakuhlehliswa.

Kulesi sihloko, sizongena emininingwaneni ye-hashing, sihlole ukuthi isebenza kanjani, ukusetshenziswa kwayo, nokuhlobana kwayo endaweni yezokuphepha ye-IT.

🚀 Yini i-hash? 

I-Hashing, ngamagama alula, iwushintsho lwezibalo oluthatha idatha yosayizi oguquguqukayo futhi iyiguqule ibe isigxivizo somunwe sedijithali esiyingqayizivele sosayizi ongashintshi. Lesi sihloko, esivame ukubizwa ngokuthi "hash", i-cryptographic digest efingqa yonke idatha yasekuqaleni engabuyiseleki emuva.

Ngamanye amazwi, cishe akunakwenzeka ukwakha kabusha idatha yoqobo kusuka ku-hashi, okwenza i-hashing ibe indlela eyodwa ebalulekile yokuqinisekisa ukugcinwa kuyimfihlo kanye nobuqotho bolwazi. 

Enye yezindlela ezivame ukusetshenziswa kakhulu ze-hashing ukuhlolwa kobuqotho bedathas. Ngokubala izigxivizo zeminwe zefayela noma iqoqo ledatha, kuba nokwenzeka ukuthola noma yikuphi ukuguqulwa noma ukuguqulwa kwedatha.

Ngisho noshintsho oluncane kudatha yasekuqaleni luzoholela esigxivizweni seminwe esihluke ngokuphelele, okwenza kube lula ukuhlonza amaphutha noma ukuzama ukukhohlisa ngokushesha. 

I-hashi iphinde ithole indawo yayo emkhakheni we-cryptography, enikeza a ukuvikelwa kwephasiwedi okuqinile kanye nolwazi olubucayi. Kunokuba ugcine amaphasiwedi ngokuqondile kusizindalwazi, amasistimu avikelekile awasheshise ngaphambi kokuwagcina.

Uma umsebenzisi efaka iphasiwedi yakhe, ibuye isheshiswe futhi iqhathaniswe nenani eligciniwe lokuqinisekisa. Ngakho, ngisho noma kwenzeka ukufinyelela okungagunyaziwe kusizindalwazi, amagama ayimfihlo ahlala engaqondakali.

 Kodwa-ke, akuwona wonke ama-algorithms we-hashing adalwe alinganayo. Ezinye zibhekwa njengeziphelelwe yisikhathi noma zisengozini yokuhlaselwa okuthuthukile kwe-cryptographic.

Ochwepheshe bezokuphepha batusa ukusetshenziswa kwama-algorithms aqinile futhi asungulwe kahle, njenge-SHA-256 noma i-SHA-512, ukuze kuqinisekiswe ukuphepha okuphelele.

 🚀Kungani i-hashi?

Kubalulekile ukusebenzisa i-hash ukuze ukwazi ukuvikela ukuthengiselana osekwenziwe kakade kanye nalezo ezizayo.

Uma ukuguqulwa sekwenziwe kunethiwekhi, kuzodingeka ukuthi uguqule wonke amabhlogo wangaphambilini kanye nama-hashes ahlobene nawo. Uma senza ukuguqulwa kuyo yonke inethiwekhi, i-hashi ezokhiqizwa izoba ngeyakho.

Kuzodingeka uqhathanise i-hashi yakho kanye neyenethiwekhi ukuze ungaqinisekisi umsebenzi.

Ngempela, i-hashi ingenye yezinto ezibalulekile kumthethosisekelo wesihlahla sikaMarkel. Ngakho-ke kuyenzeka ngama-cryptocurrencies athile ahlanganise imisebenzi eminingi yama-hashi enezakhiwo ezihlukile kwezinye.

🚀Imithetho kanye nezakhiwo ze-hashing

Ukuze umsebenzi we-hash ulungile, kufanele ulandele imithetho nezakhiwo ezithile:

• Ubude besiginesha esetshenzisiwe kufanele ihlale ifana kungakhathaliseki ukuthi ingakanani idatha oyifakile. Kamuva, sizobona ukuthi bungakanani ubude bezigxivizo zeminwe emisebenzini ye-hashi.
• Kusukela ezigxivizweni zeminwe, akunakwenzeka ukubuyisela idatha yangempela: imisebenzi eku-hashi isebenza ohlangothini olulodwa kuphela.
• Akwenzeki ukubikezela isiginesha. Akunakwenzeka ukuthi uzame ukucabanga isiginesha ngokuhlola idatha.
• Uma unedatha eminingi, idatha ngayinye kufanele babe namasignesha ahlukene.

🚀Isebenza kanjani i-hashing

Eqinisweni, i-hashing iyinqubo ezenzakalelayo engase ifaniswe namakhodi athunyelwa phakathi nempi.

Ngokombono, kuyadingeka nje ukwengeza, ukushintsha, noma ukuguqula izinhlamvu ezihlukene zomlayezo ukuze uthole ikhodi okufanele yehluke ngokuphelele kwezinye futhi ihluke ngohlobo lwayo.

I-hashi ikuvumela ukuthi ukhiqize ngokufaka okuhambisanayo okuguquguqukayo, ikhodi engaguquki. Ngisho noma ubude beyunithi yezinhlamvu bungaphezu kwezinhlamvu ezingu-5 noma ngisho namagama angu-500, kusafanele ibuyisele umphumela onosayizi owodwa kuphela.

Imisebenzi ye-Hash yonke iqukethe izici ezifanayo. Okuyizi:

• Ukunquma : ngokuqondile, ngemva kokudlula emshinini wokugaya womsebenzi okukhulunywa ngawo, umphumela womlayezo, kuzo zonke izimo, kufanele ungaguquguquki: izindawo, umzuzu, ukuphindaphinda, ...
• La ukumelana : umphumela otholwe kumsebenzi akumele uvumele noma ubani noma nini ukuthi abuyele emuva kumlayezo wokuqala.
• Hlukanisa : umphumela otholwe kumsebenzi ophathelene nemilayezo emibili efanayo akumele ufane kodwa uhluke futhi ubonakale kalula.
• Unique : ngemva kokuhlaziya, imilayezo emibili ehlukene ayikwazi ukuphuma nomphumela ofanayo.
• Kuyasebenza : umphumela akufanele ubambezeleke, kufanele ube ngokushesha.

Ngakho-ke intshisekelo ye-hashing iwukumisa okuqukethwe ukuze kube nenombolo efanayo yezinhlamvu futhi ukwazi ukuhlonza idatha ngendlela ehlukile yomlayezo owodwa oya komunye.

🚀 Ukusetshenziswa okungokoqobo kwemisebenzi ehlukene ye-hashi

Lolu hlu aluphelele nhlobo, njengoba kukhona okunye ukusetshenziswa okuningi kwale misebenzi:

• Qhathanisa amaphasiwedi : njengoba kushiwo, lapho ulondoloza iphasiwedi yakho, yonke into yenzelwa ukuphepha.
• Ukuqinisekiswa kwedatha yakho elandiwe : kwezinye izimo ngokwesibonelo, uma ulanda ifayela ku-inthanethi, isiginesha yoqobo yefayela iyatholakala.

Iboniswa ngokuqondile kusayithi noma kwelinye ifayela elihlukile. Ukuze uqinisekise ukuthi ifayela lilandwe ngendlela efanele, uzomane uhlole ukuthi isiginesha yefayela iyafana yini naleyo enikeziwe.

• Isiginesha yedijithali noma ye-elekthronikhi yamadokhumentis: lapha, imibhalo ithunyelwa ngqo kumsebenzi we-hash. Amadokhumenti athunyelwa ngesikhathi esifanayo nezigxivizo zeminwe. Umsebenzisi kuzodingeka acacise kuphela izigxivizo zeminwe ezitholiwe futhi aqinisekise ukuthi zihambisana nokubalwa kwezigxivizo zeminwe ezinamathiselwe kudatha etholiwe.
• Ukusetshenziswa kwetafula le-hashi : uma ufuna ukukwenza, kuzodingeka uyisebenzise ekuthuthukisweni kwesofthiwe ukuze wenze yonke into ihambe kahle.
• Mayelana nokugcinwa kwedatha : ukuze uqinisekise ukuba khona kwedokhumenti, kuzodingeka uziqinisekise ukuthi isignesha nayo ikhona, ngakho awudingi ukuyigcina futhi. Lokhu kuyancomeka kakhulu, ngoba uma kuyifayela elikhulu, kuzokuthatha isikhathi esincane kakhulu ukubala isignesha yesigxivizo seminwe esibhalisiwe.

🚀Usebenzisa i-hash coding

Isici esigcina amaphasiwedi akho evikelekile yileso esithatha umbhalo wephasiwedi yakho siwugaye sibe isiginesha. Lesi siginesha sibizwa nangokuthi umkhondo ".

Ikhompyutha ayithumeli iphasiwedi yakho kuseva, idlulisa kuphela isiginesha yakho yephasiwedi. Ngalesi sikhathi, iseva ayilondolozi iphasiwedi, kodwa kunalokho isiginesha egayiwe.
