Ob peb xyoos dhau los, Digital Fortress los ntawm Dan Brown tau ua rau kuv mloog thiab ib yam tshwj xeeb tau nyam ntawm kuv lub siab. Kryptos, duab puab los ntawm Jim Sanborn uas suav nrog cov ntawv sau uas thawj ob ntu tau nkag los ntawm Vigenère cipher. Kuv pib nkag mus rau hauv cryptography thiab pom tias muaj kev lom zem npaum li cas (Dan Brown cov kiv cua yuav nkag siab meej). Qhov program no tso cai rau koj los encrypt/decrypt cov ntawv siv lo lus tseem ceeb.
Kauj ruam 1: Cov txheej txheem
Tabula recta tau siv los encrypt/decrypt cov ntawv dawb/cipher. Nws suav nrog cov tsiaj ntawv sau tawm 26 zaug hauv kab sib txawv, txhua tus tsiaj ntawv tau hloov pauv mus rau sab laug piv rau cov tsiaj ntawv yav dhau los. Raws li tus cipher yuav tsum siv cov ntawv Askiv nkaus xwb, muaj qee qhov kev txwv/kev ua haujlwm siv hauv cov cai.
Cia khawb hauv!
Cia peb hais tias peb xav kom nkag siab cov ntawv "INSTRUCTABLES IS FUN", siv lo lus tseem ceeb "ROBOT". Lo lus tseem ceeb tau rov ua dua kom nws phim qhov ntev ntawm cov ntawv dawb. Thaum peb pib nrog thawj tsab ntawv los ntawm cov ntawv yooj yim "Kuv" thiab los ntawm lo lus tseem ceeb "R", siv tabula recta (saib daim duab), peb tuaj yeem pom tias thawj tsab ntawv ntawm cipher yog "Z".
Plain text: INSTRUCTABLES IS FUNKeyword: ROBOTROBOTROBOTROBOTCipher: ZBTHKLQUOUCSTWLWIO
Rov ua qhov no rau txhua tsab ntawv hauv qab no thiab koj tau txais koj thawj tus lej! Los yog siv cov cai kom mus txog ntawd sai dua:)

Caesar Cipher Program hauv Python: 4 Cov Kauj Ruam
Caesar Cipher Program hauv Python: Caesar Cipher yog lub qub thiab siv dav cipher uas yooj yim rau encrypt thiab decrypt. Nws ua haujlwm los ntawm kev hloov cov tsiaj ntawv ntawm cov tsiaj ntawv los tsim cov tsiaj ntawv tshiab (ABCDEF tuaj yeem hloov pauv ntau dua 4 tus ntawv thiab yuav dhau los ua EFGHIJ) .Caesar C

Yuav Ua Li Cas Thiaj Li Tshem Tawm Lub Computer Nrog Cov Kauj Ruam Yooj Yim thiab Duab: 13 Kauj Ruam (nrog Duab)
Yuav Tsum Tshem Tawm Lub Khoos Phis Tawj Li Cas Nrog Cov Kauj Ruam Yooj Yim thiab Duab: Nov yog cov lus qhia txog yuav ua li cas tshem lub PC. Feem ntau ntawm cov khoom siv yooj yim yog hloov pauv thiab tshem tawm tau yooj yim. Txawm li cas los xij nws yog ib qho tseem ceeb uas koj tau koom nrog nws. Qhov no yuav pab tiv thaiv koj kom tsis txhob poob ib feem, thiab tseem ua rau kev rov ua dua tshiab
