Whakarāpopototia te tuhinga:  "He torutoru noa iho ngā wā i roto i te oranga o te tangata e pāngia ai e ia te nui o te raruraru", i tuhituhi a Charles Dickens mō te whai i tētahi potae i roto i The Pickwick Papers. Engari i roto i te ao o nāianei, ka taea hoki te kōrero i te mea kotahi mō te wareware i tētahi kupuhipa nui. Inaianei kua tahuri nga kairangahau ki te kaituhi nui o Wikitoria hei āwhina ki te kimi huarahi hei hanga i nga kupuhipa kia haumaru, kia maumahara hoki. Kua huri nga kairangahau ki nga mahi a Charles Dickens (kua whakaahuatia) ki te whakaputa i nga kupuhipa haumaru engari e maumahara ana kia rite ki te rangahau hou a nga kairangahau rorohiko o te US. I whakamahia e ratou he tauira mai i te kaupapa pea ki te tirotiro i te putanga o nga reta i roto i a Mr Dickens's Tale of Two Cities ki te whakaputa i nga kupuhipa hou. I whakamahia e rātau he tauira mai i te ariā tūponotanga hei whakamātautau i te putanga o ngā reta i roto i te Mr Dickens' Tale of Two Cities hei whakaputa i ngā kupuhipa hou. E mahi ana te tukanga mā te rapu i ngā pūāhua e rua e puta tahi ana, ā, ka whakaputa i tētahi pūāhua tuatoru e kore e puta. E hia miriona ngā kaiwhakamahi ipurangi e whakawhirinaki tonu ana ki ngā kupuhipa māmā ki te wawahi pēnei i te <unk>qwerty<unk> me te <unk>123456<unk>, engari he maha ngā tāngata e whiriwhiri ana ki te whakamahi i ngā huinga pūāhua matatini ake mō ā mātou pūkete ipurangi. Heoi anō, kua kitea e tētahi rangahau hou ko ēnei kupuhipa āhua noa iho, he mea mārama ake pea ki te hacking i te mea e whakaaro ana koe. Kua whakaaturia e ngā kairangahau ka taea te pakaru i ngā kupuhipa pēnei i te <unk>mnbvcxz<unk>, <unk>qaz2wsx<unk> me te <unk>adgjmptw<unk> i roto i ngā hēkona - ā, ko te tāpiri i ngā tau ki ō waehere he iti noa iho te kaha o te kaha. I mahia te tātaritanga e te kamupene manaaki WP Engine mā te whakamahi i te 10 miriona kupuhipa i tukuna tata nei e te kaitohutohu haumarutanga a Mark Burnett. I kitea e rātau he maha ngā kupuhipa matatini i whakamahia e te tini o ngā tāngata. Hei tauira, ko <unk>qaz2wsx<unk> kei roto i te 30 tuatahi. I kite hoki rātau i tētahi pae tukutuku e kiia nei ko Zxcvbn i tohu i ēnei kupu he kore, he iti rānei, mō te mea e kiia nei ko te entropy. Ka whakamahia te entropy hei whakatau i te kaha o te kupuhipa i runga i te <unk>information entropy<unk>. Ka ahu mai tēnei i te ariā mōhiohio, ā, ka whangangahia ki ngā moka. Ko te nui ake o ngā moka e whakawhiwhia ana ki tētahi kupu, i runga anō i te tau...
I whakamahia e te tohunga rorohiko te ariā tūponotanga ki te kōrero a Dickens o Ngā Taone e Rua. I kitea e rātau ka taea e te huarahi te whakaputa kupuhipa tupono engari e mōhiotia ana. He haumaru ngā kupuhipa 56-bit engari he māmā ake te mahara, e kī ana te kaipūtaiao. I kii ia ka taea hoki te whakamahi i te huarahi ki te hanga kupuhipa mai i nga imeera.
