Chimwe chezvikamu zvakajairika zvekuongororwa kwenhamba ndezve iro boka re Nhamba huru, inotsanangurwa senge iyo inoumbwa ne nhamba dziri zvinongoparadzaniswa pachavo (zvichikonzera 1) uye na1 (zvichikonzera mavari).
Kana uchitaura nezve 'ive inoparadzaniswa'Iri kureva izvozvo mhedzisiro inofanirwa kuve yakazara nhamba, nekuti zvichinyatso kutaura, ese manhamba akapatsanurwa nenhamba dzese (kunze kwe0), ichiburitsa manhamba kana zvikamu zvishoma.
Kubva pane zvataurwa pamusoro, mamwe mhedziso akakosha anogona kutorwa:
- Kunyangwe nhamba haigone kuve yekutanga, sezvo ese kunyange manhamba ari akapatsanurwa, kuwedzera kune maviri, nenhamba yakati kuti inoguma maviri. Kunze kweiyi nhamba mbiri pachayo., iyo inonyanya kukosha nekuzadzisa yakakosha mamiriro ekungove inokamurwa neayo ega uye neyuniti.
- Nhamba dzisina kujairikapachinzvimbo, ehe vanogona kunge vari babamunini, kusvika padanho rekuti haigone kuratidzirwa sechigadzirwa cheimwe nhamba mbiri.
Mienzaniso yenhamba yepamusoro
Iwo makumi maviri ekutanga prime manhamba akanyorwa pazasi semuenzaniso (cherekedza kuti nhamba 1 haina kuiswa mune ino runyorwa, sezvo isingasvike iyo yepamusoro nhamba mamiriro).

Prime Nhamba Zvikumbiro
Iyo Nhamba huru akakosha zvakanyanya mumunda wemasvomhu ekushandisa, kunyanya mumunda wekomputa uye kuchengetedzwa kwekutaurirana rakapotsa.
Zvinoitika kuti iyo yese encryption maitiro Iyo yakavakirwa pahwaro hwehuwandu hwepamberi, sezvo mamiriro ehukuru anoita kuti zvikonere kuodza idzi nhamba; izvo zvinoreva kuti zvakanyanya kunetsa kutsanangura musanganiswa wemadhijiti pasi pakavanzika password.
Kugoverwa kwenhamba yepamusoro
Kushanda nenhamba dzekutanga kune hunhu husingawanzoitika mumasvomhu, izvo zvinoita kuti zvinakidze kune vazhinji nyanzvi dzemasvomhu: chokwadi chekuti rondedzero zhinji dzedzidziso hadzi pfuure chikamu che fungidzira.
Kunyangwe hazvo nhamba dzekutanga dzakaratidzwa kunge dzisingapere, hapana humbowo hwekongiri hwekugovera dzadzo pakati pezviverengero: kududzwa kwese kweiyo prime nhamba theorem inodaro iyo yakakura nhamba, iyo yakaderera mukana wekusangana neyekutanga, asi hapana zvirevo zvinotsanangurwa zvinonyatsotsanangura kuti kugoverwa uku kwakamira sei, kuti ugone kuziva nhamba dzese dzekutanga.
Iko kusanganisa pakati pekushanda kwenhamba yepamusoro uye iyo zvirahwe Vakatenderedza vanoita kuongorora kwavo kwekufarira kukuru kwemasvomhu, uye kuti makomputa akagadzirirwa kuwana huwandu hukuru hukuru. Pari zvino, iyo inonyanya kuzivikanwa prime prime ine inopfuura 17 mamirioni manhamba, chiverengero chinogona kuverengerwa chete kuburikidza nemakomputa anopindura kune akaomesesa algorithms.
