Yog tias koj txiav txim siab ib daim ntawv dawb, qhov tseeb, koj tsuas yog encrypted nws. Nrog rau cov ntawv cipher niaj hnub zoo li AES, koj yuav zoo li tau txais tus lej tsis tseem ceeb. … AES hauv hom streaming txawm li cas los xij, (xws li CTR) siv tib lub luag haujlwm rau ob qho tib si encryption thiab decryption thiab yog li yuav tsuas ua rau cov ntawv ciphertext.
Puas cov ntawv nyeem tau muab zais?
Plaintext yog dab tsi encryption algorithms, lossis ciphers, hloov an encrypted lus rau hauv. Nws yog cov ntaub ntawv nyeem tau - suav nrog cov ntaub ntawv binary - hauv daim ntawv uas tuaj yeem pom lossis siv yam tsis xav tau tus yuam sij decryption lossis decryption ntaus ntawv.
Koj puas tuaj yeem decryption encryption?
Rau qhov laj thawj, ib qho txheej txheem encryption feem ntau siv pseudo-random encryption tus yuam sij tsim los ntawm algorithm. Nws muaj peev xwm decrypt cov lus yam tsis muaj tus yuam sijtab sis, rau lub tswv yim zoo tsim encryption, yuav tsum muaj kev suav ntau thiab kev txawj ntse.
Puas decryption txhaum cai?
Decryption yog unlawful, tshwj tsis yog los ntawm tus neeg npaj thiab tso cai tau txais cov ntsiab lus.
Yuav ua li cas kuv hloov cov ntawv plaintext rau ciphertext?
Tus sender hloov cov lus yooj yim rau ciphertext. Cov txheej txheem no yog hu ua encryption (qee zaum encipherment). Lub ciphertext yog kis mus rau lub receiver. Tus txais yuav hloov cov lus ciphertext rov qab rau nws daim ntawv plaintext.
