He aha ai e whakamahi ai i tā mātou kaitiaki PDF?
He āhuatanga nui te tiaki i ngā tuhinga māharahara mā tētahi kupu huna mō te nōhanga me ngā pakihi. Ka ārahina e ngā tikanga maha — pēnei i ngā ture tiaki raraunga, ngā tikanga ā-pakihi, ngā herenga kirimana rānei — te tiaki i ngā ihirangi māharahara. Ka whakamuna e LlamaPDF tōu kōnae mā te whakamuna AES, tētahi paerewa whakamuna e whakamahia ana e ngā pūnaha tūmau, e ngā tari kāwanatanga, me ngā hinonga pūtea puta noa i te ao. Ka whakarite tēnei ko ngā tāngata e mōhio ana ki te kupu huna anake ka āhei ki te huaki, ki te tā, rānei ki te tāruarua i ōu ihirangi. Ka oti ngā mahi katoa i tō tirotiro — kāore tō kōnae e tukuna ana ki ā mātou tūmau. He taputapu tino tika tēnei mō ngā kaipūtea, ngā rōia, ngā kaitiaki hauora, me ērā atu mahi e aro ana ki ngā ihirangi māharahara ia rā ia rā.
He mea ngātahi te tiaki PDF me ērā atu tikanga haumaru. I muri i te whakaatianga o tō kōnae, ka taea e koe te tango i te tiaki mēnā ka hiahia koe ki te whakatikatika, te tāpiri i tētahi tohu wai mō ngā tuhinga tūmataiti, rānei te whakamāmā i tō PDF i mua i te tuku. Ka hono ngā tikanga katoa hei tiaki nui ake i ōu tuhinga.
He aha te tiaki PDF?
Ka whakamuna te tiaki PDF i te ihirangi o tētahi kōnae mā te whakamuna symmetric, e hiahia ana ki tētahi kupu huna ki te huaki. Ka taea e ngā taumata whakamuna e rua — AES-128 me AES-256 — te tiaki i ngā kōnae; ko AES-256 tōna kaha rawa atu, e whakamahia ana i roto i ngā tūāhuatanga haumaru-tino-nui. Ka āhei hoki ngā tiaki PDF ki te tautuhi i ngā mana — ka āhei pea te tirotiro me te kore tā, rānei te huaki me te kore tāruarua. Ko ngā tiaki kua tūnohia mai e ngā paerewa PDF, nō reira ka tautokona e ngā tirotiro me ngā pūmanawa PDF katoa i te ao. Ka tiakina e tēnei momo haumaru ōu ihirangi āhei kē i te wāhi katoa ka tukuna ana tō kōnae.
