Thaum cov ntawv dawb hloov mus rau hom ntawv nyeem tsis tau, hom ntawv ntawd raug hu ua cipher-text.
Kuv yuav encrypt cov ntawv dawb li cas?
Muaj ob txoj hauv kev uas cov ntawv sau yooj yooj yim tuaj yeem hloov kho kom tau txais cov ntawv cipher: Hloov cov txheej txheem thiab Hloov cov txheej txheem
- Txoj Kev Hloov Hloov: Cov txheej txheem hloov pauv suav nrog kev hloov cov ntawv los ntawm lwm cov ntawv thiab cov cim. …
- Txoj Kev Hloov Pauv:
Yuav siv cov txheej txheem twg los hloov cov ntawv plaintext rau ciphertext?
Tus xa khoom 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.
ntawv nyeem yog dab tsi?
Ciphertext yog dab tsi encryption algorithms, lossis ciphers, hloov cov lus qub rau hauv. Cov ntaub ntawv tau hais tias yuav tsum tau encrypted thaum ib tus neeg lossis cov cuab yeej tsis muaj tus lej cim nyeem tsis tau. Lawv, los yog nws, yuav xav tau lub cipher los decrypt cov ntaub ntawv.
cipher yog dab tsi thiab nws hom?
Definition: Cipher is an algorithm uas yog siv rau cov ntawv dawb kom tau txais cov ntawv cipher. Nws yog qhov tsis tau nyeem tau ntawm qhov encryption algorithm. … Muaj ntau hom ntawv ciphers, qee qhov yog: Hloov Cipher: Qhov no muaj lwm txoj hauv kevqhov tseeb. Nws tseem hu ua Caesar cipher.
