Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Putanga: Ko te rangahau mātauranga nui ki te whakamunatanga he mea hou noa iho; i timata noa i waenganui o nga tau 1970. I nga wa tata nei, i hangaia e nga kaimahi IBM te hātepe i riro hei Federal (arā, US) Paerewa Whakamunatanga Raraunga; Whitfield Diffie me Martin Hellman i whakaputa i to raatau algorithm whakaaetanga matua; a i whakaputaina te hātepe RSA i roto i te pou Scientific American a Martin Gardner. Whai muri i ta raatau mahi i te 1976, i rongonui te whakaaro ki nga punaha whakamunatanga i runga i nga raru pangarau he ngawari ki te korero engari he uaua ki te whakatau. Mai i taua wā, kua riro te whakamunatanga hei taputapu e whakamahia whānuitia ana i roto i nga whakawhitiwhitinga, i nga whatunga rorohiko, i te haumarutanga rorohiko i te nuinga. Ka taea e ētahi pūkenga whakamunatanga hōu anake te pupuri i ō rātou kī ki te mea he uaua ētahi raruraru pāngarau, pēnei i te whakarea tau tōpū, i ngā raruraru kōaro kōaro rānei, nō reira he hononga hohonu ki te pāngarau ātaahua. He ruarua noa iho ngā pūnaha whakamunatanga e kitea ana he tino haumaru. Ko te papamahi kotahi te kotahi, ā, i whakamātauria e Claude Shannon. He torutoru ngā hātepe matua kua kitea he haumaru i raro i ētahi whakaaro. Hei tauira, ko te koretake o te whakawātea i ngā tau tōpū tino nui ko te pūtake ki te whakapono he haumaru a RSA, me ētahi atu pūnaha, engari ahakoa tērā, kāore i te wātea te whakamātautau o te ārai i te mea kei te tūwhera tonu te raruraru pāngarau. I roto i te mahi, kei te whakamahia whānuitia ēnei, ā, e whakaponohia ana e te nuinga o nga kaitirotiro whai mana kaore e taea te pakaru. He pūnaha rite ki te RSA, pēnei i tētahi na Michael O. Rabin e kitea ana he haumaru i te mea e kore e taea te n = pq; he tino kore e taea te whakamahi. Ko te raruraru logarithm motuhake ko te pūtake mo te whakapono etahi atu cryptosystems he haumaru, a ano, i reira e pā ana, iti pūnaha mahi e he pono haumaru e pā ana ki te solvability ranei insolvability raruraru log motuhake.Rite ki te kia mōhio o te hītori cryptographic, cryptographic hātepe me ngā kaihoahoa pūnaha me hoki te whakaaro...  Pātai: Whakaritea tētahi ara e whakamahia ai te whakamunatanga hei taputapu?
