Chirongwa chakareruka chekusayina dhijitari

Kuwana zvakavanzika, chokwadi uye kuvimbika kweshoko kunoitwa nekunyora meseji usati watumira kune unogamuchira.

Ehe, kiyi inoenderana neruzhinji yemugamuchiri inofanirwa kushandiswa kune ino encryption. Kiyi yeruzhinji inoshandiswa kusevha uye kiyi yakavanzika inoshandiswa pakumisikidza.

Certification inoshandiswa kudzivirira kutsiva kiyi yemanyepo kiyi. Chitupa chitupa chechokwadi chakasainwa nemunhu akavimbika (institution), anonzi CA (Certification Authority). Setifiketi rinowanzo kuve nemhando yegwaro remagetsi.

Chitupa chine ruzivo rwechokwadi runoratidza muridzi. Kazhinji, iyo CA inosimbisa mvumo inobvumikisa kuti ruzivo rwuri kutsanangura muridzi wechokwadi nderechokwadi uye kuti kiyi yeruzhinji ndeyayo.

Chitupa zvakare chine nguva yekusimbisa nguva iyo iyo data yakasimbiswa inogona kutorwa seyakanaka. Kunyangwe inguva yekubvumidzwa kupi, makiyi akasimbiswa anogona kutorwa seakakora, i.e. apo paine fungidziro yekuti munhu asina kubvumirwa auya aine kiyi yekuvanzika yakavanzika inoenderana nekiyi yakavanzika yeruzhinji.

Iyo CA inopa mvumo inofanirwa kuchengetedza runyorwa rwezvitupa zvisingabvumirwe uye zvakapera. Ehe, kudzvanywa kiyi zvakare rudzi rwechitupa.

Chimiro chechimiro chechitupa chaicho

mhando - inozivisa nezve inotevera vhezheni yesitifiketi

Nhamba ye seri - yakasarudzika chitupa nhamba

Algorithm ID (algorithm, parameter) - dijitari siginecha algorithm uye mhando yemaparameter

exhibitor - iyo CA yakapa chitupa

Nguva yekubvumidzwa   - yekutanga uye yekupedzisira kupera zuva rechitupa

chidzidzo - zita rebato rakagadzirirwa chitupa

Kiyi yeruzhinji - nyaya yeruzhinji kiyi ine algorithm chiziviso uye paramende kukosha

siginicha - siginecha yeCA.
