Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Public-key cryptography inoshandiswawo pakuita zvirongwa zvekusaina kwedhijitari. Siginicha yedhijitari inoyeuchidza siginicha yakajairika; ese ari maviri ane hunhu hwekuti zviri nyore kuti mushandisi agadzire, asi zvakaoma kuti mumwe munhu agadzire. Masiginecha edhijitari anogonawo kubatanidzwa zvechigarire kumashoko ari kunyorwa; ipapo haagoni ku'chinjwa' kubva pane rimwe gwaro kuenda kune rimwe, nokuti kuedza kupi nokupi kuchaonekwa. Muzvirongwa zvekusaina kwedhijitari, pane ma algorithms maviri: imwe yekusaina, umo kiyi yakavanzika inoshandiswa kugadzirisa meseji (kana hash yemeseji, kana zvese zviri zviviri), uye imwe yekusimbisa, umo kiyi yeruzhinji inoenderana inoshandiswa nemeseji kuti uone huchokwadi hwekusaina. RSA neDSA ndedzimwe nzira mbiri dzinoshandiswa zvikuru pakusaina magwaro. Masiginecha edhijitari akakosha pakushanda kwezvivakwa zveveruzhinji uye zvirongwa zvakawanda zvekuchengetedza network (semuenzaniso, SSL / TLS, maVPN mazhinji, nezvimwewo). Somuenzaniso, kuomarara kweRSA kune chokuita nechinetso chokuparadzanisa nhamba dzakakwana, nepo Diffie<unk>Hellman neDSA zvine chokuita nechinetso che logarithm yakasiyana. Kuchengeteka kwe elliptic curve cryptography kwakavakirwa panhamba dzenyaya dzinosanganisira elliptic curves. Nemhaka yokuoma kwezvinetso zvacho, manyorerwo ezvinokosha pachena akawanda anosanganisira mabasa akadai sokuwedzera uye kuwedzera, ayo anodhura zvikuru pakuverenga kupfuura nzira dzinoshandiswa mumanyorerwo ezvinokosha, zvikurukuru nehukuru hwezvinokosha. Somugumisiro, pachena-kiyi cryptosystems vari kazhinji hybrid cryptosystems, umo kutsanya yepamusoro symmetric-kiyi encryption algorithm rinoshandiswa shoko pacharo, apo akakodzera symmetric kiyi rinotumirwa shoko, asi encrypted vachishandisa pachena-kiyi algorithm. Nenzira yakafanana, zvirongwa zvekusaina zvehybrid zvinowanzo shandiswa, umo basa rekunyora rakanyorwa rinoverengerwa, uye chete iyo inoguma hash yakasainwa nedhijitari.  Mubvunzo: chii chinonzi siginicha yedhijitari?
dzakakosha mukushanda kwezvivakwa zveveruzhinji
