Gukora hash kuva kumurongo
Ntibishoboka kubyara kode yerekana amashusho kuva kumurongo ukoresheje algorithms zitandukanye nka SHA256, ADLER32, nibindi byinshi.

Imikorere ya Hash: Intwari zitaririmbwe za Data Ubunyangamugayo, Umutekano, na Cryptography
Mwisi yubumenyi bwa mudasobwa hamwe na cryptography, imikorere ya hash igira uruhare runini mukurinda ubusugire numutekano byamakuru. Imikorere ya hash ni algorithm ya mibare ifata ibyinjijwe (cyangwa "ubutumwa") kandi ikabyara ingano ihamye yumurongo winyuguti, izwi nkigiciro cyagaciro cyangwa igogora. Muri iyi ngingo, tuzasesengura ishingiro ryimikorere ya hash, imikoreshereze yabo, nimpamvu zituma bagira uruhare mukurinda amakuru yihariye.
Imikorere ya Hash yashizweho kugirango yihute kandi neza, gutunganya amakuru yubunini ubwo aribwo bwose. Bakoresha imibare igoye kugirango bahindure ibyinjijwe mubisohoka bidasanzwe, hamwe nurufunguzo ruranga ni uko niyo mpinduka ntoya mubyinjijwe bivamo ibisubizo bitandukanye rwose. Uyu mutungo, uzwi nkingaruka za avalanche, utuma ibikorwa bya hash ari ntagereranywa mugukomeza amakuru yuzuye no kumenya ibyahinduwe bitemewe.
Imwe muma progaramu yibanze yimikorere ya hash ni mukugenzura ubusugire bwamakuru. Kubara hash agaciro ka dosiye cyangwa ubutumwa, birashoboka gukora igikumwe cyihariye cyerekana urutoki. Ihinduka ryose ryakurikiyeho, nubwo ryaba rito, rizaganisha ku gaciro keza hash. Ibi bifasha abakoresha kugereranya hash kubarwa nagaciro kambere kugirango barebe ko amakuru atayangijwe, bitanga uburyo bukomeye bwo kumenya ruswa cyangwa guhindura nabi.
Imikorere ya Hash ikoreshwa cyane mububiko bwibanga no kwemeza sisitemu. Aho kubika ijambo ryibanga mu buryo butaziguye, sisitemu isanzwe ibika hash agaciro kijambo ryibanga. Iyo umukoresha yinjiye ijambo ryibanga, sisitemu ibara hash agaciro kinjiza kandi ikagereranya nigiciro cyabitswe. Ubu buryo butanga urwego rwumutekano rwiyongereye, nkaho igitero cyabonye amakuru yabitswe, ntibazabona uburyo bwibanga ryibanga ubwabo.
Imikorere ya Hash nikintu cyingenzi cyumukono wa digitale hamwe nubutumwa bwo kwemeza ubutumwa (MACs). Imikono ya digitale ikoresha rusange-urufunguzo rwibanga kugirango igenzure ukuri kwubutumwa, mugihe MACs yemeza ubunyangamugayo nukuri kwamakuru. Muri ibyo bihe byombi, imikorere ya hash ikoreshwa mugutanga igogora ryubutumwa cyangwa amakuru, hanyuma bigahishwa cyangwa bigahuzwa nurufunguzo rwibanga. Ibi bituma abayakiriye bagenzura inkomoko nubusugire bwamakuru bakiriye.
Hano hari hash imikorere myinshi algorithms irahari, buriwese ufite imbaraga nintege nke. Ingero zirimo MD5, SHA-1, SHA-256, nibindi byinshi. Nyamara, iterambere mu mbaraga zo kubara ryatumye zimwe muri izo algorithm zidafite umutekano, kuko havumbuwe intege nke. Niyo mpamvu, ni ngombwa gukoresha imikorere ya hash ifatwa nkumutekano ukurikije amahame agezweho, nkumuryango SHA-2 cyangwa SHA-3 umuryango wa algorithms, wasuzumwe cyane kandi usesengurwa ninzobere murwego.
Imikorere ya Hash ni umusingi wibanga rya kijyambere kandi igira uruhare runini mugukomeza amakuru yuzuye, ukuri, numutekano. Ubushobozi bwabo bwo gukora indangagaciro zidasanzwe kubintu byinjiza bitandukanye bituma biba ngombwa mugusuzuma ubusugire bwamakuru, kubona ijambo ryibanga, gutanga umukono wa digitale, no kwemeza ukuri kwubutumwa. Gusobanukirwa imikorere ya hash nibikorwa byayo nibyingenzi kubantu bose bakorana namakuru yihariye, kuko batanga umusingi ukomeye wo kurinda amakuru mumiterere yiki gihe.
