Cov ciphers hloov pauv yog ib txoj hauv kev rau kev nkag lossis zais cov lus kom cov kab lus lossis kab lus tsis tuaj yeem nyeem los ntawm ib tus neeg uas tsis paub tus lej. Ciphers feem ntau yog ua los ntawm hloov ib tsab ntawv rau lwm tus. Lawv yog txoj hauv kev lom zem rau pab pawg ntawm cov phooj ywg kom xa cov ntaub ntawv rov qab los yam tsis muaj lawv cov phooj ywg (lossis cov kws qhia ntawv) tuaj yeem nyeem cov ntaub ntawv. Pib ua haujlwm nrog tus lej nkag los ntawm koj tus kheej cov ntawv cipher thiab nkag siab cov lus lossis kab lus yooj yim.
Cov kauj ruam
Qauv Cuam Tshuam
Qauv Augustus Code Paragraph
Ntu 1 ntawm 3: Xaiv Qhov Hloov Hloov
Kauj Ruam 1. Rov qab cov tsiaj ntawv los tsim cov ntawv cipher yooj yim
Cov ciphers hloov ua haujlwm los ntawm kev tsim cov tsiaj ntawv tsis sib xws, tso cai rau koj hloov cov tsiaj ntawv rau lwm cov tsiaj ntawv. Rau qhov hloov pauv yooj yim cipher, tsuas yog siv cov tsiaj ntawv rov qab, yog li "a" dhau "z," "b" dhau los "y," "c" ua "x," thiab ntxiv rau.
- Qhov hloov pauv tus lej yuav nyeem: ZYXWVUTSRQPONMLKJIHGFEDCBA.
- Tus niam ntawv thib ob no feem ntau hu ua "ciphertext."
Kauj Ruam 2. Hloov txhua tsab ntawv nrog tsab ntawv 3 ua ntej nws rau tus cipher nyuaj dua
Tsuas yog sau cov tsiaj ntawv rov qab rau koj tus lej nkag yooj yim heev thiab yuav yooj yim rau tawg. Yog tias koj xav tau cov ntawv zais sib txawv, hloov txhua txhua tsab ntawv nrog tsab ntawv uas tuaj 3 ua ntej nws hauv cov tsiaj ntawv.
Raws li qhov piv txwv yooj yim, siv tus lej no, lo lus "CAT" nyeem "ZYQ."
Kauj Ruam 3. Hloov tus lej 5-tsab ntawv tsis raws cai rau txhua tus tsiaj ntawv
Qhov no yog hu ua Bacon's Code. Bacon's Code hloov pauv txhua tsab ntawv ntawm tus niam ntawv Askiv nrog 5-tsab ntawv ua ntu zus. Cov kab ntawv no pib nrog "AAAAA" thiab ntxiv "B" s raws li qhov kev txiav txim siab. Yog li, hauv Bacon's Code, A = AAAAA; B = AAAAB; C = AAABA; D = AAABB thiab lwm yam. Tswj cov qauv no txhawm rau sau tas cov niam ntawv, lossis tsim koj tus kheej 5-ntawv hloov chaw.
- Thaum nyeem cov lus hauv Bacon's Code, ncua txhua 5 ntawv los txiav txim siab tsab ntawv. Piv txwv li, cov lus "AAABAAABAAABABBABABB ABBBBAABBBABBBAABBABABABABABAAABAAABAAABAAABAAABAAABAAABAAABAAABAAABAAABAAABAAABAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA reads" CELL PHONE"
- Nkag siab cov lus hauv Bacon's code online ntawm:
Ntu 2 ntawm 3: Txheeb Xyuas Koj Cov Ntawv Hloov
Kauj Ruam 1. Sau 2 kab ntawv ua ntu zus ntawm ib daim ntawv
Sau tawm tus ntawv Askiv tus qauv nyob rau sab saud ntawm daim ntawv: ABCDEFGHIJKLMNOPQRSTUVWXYZ. Tom qab ntawd, hauv qab ntawd, sau cov ntawv hloov chaw. Hloov txhua tsab ntawv nrog tsab ntawv 3 ua ntej nws hloov pauv nyeem: XYZABCDEFGHIJKLMNOPQRSTUVW. Yog li, koj daim ntawv cipher yuav zoo li no:
- A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
- X Y Z A B C D E F G H I J K L M N O P Q R S T U V W
Kauj Ruam 2. Siv lub tshuab hluav taws xob hloov pauv online kom txuag tau ntawv
Yog tias koj xav tau tsis tas yuav siv zog sau ntawv los ntawm txhais tes tag nrho cov lej sib tshooj-thiab txhua kab lus-sim siv lub vev xaib cipher. Cipher cov vev xaib tso cai rau koj xaiv cov ntawv twg ntawm cov ntawv yuav raug hloov pauv rau txhua tus ntawv. Thaum koj tau hloov kho qhov hloov pauv, koj tuaj yeem siv lub vev xaib cipher rau ob qho tib si encode thiab txiav txim siab cov lus.
- Nrhiav qhov hloov pauv lub tshuab hluav taws xob online ntawm:
- Nkag mus rau lwm qhov chaw siv tau ntawm:
Kauj Ruam 3. Ntxiv cov cim rau hauv tus cipher kom nws nyuaj rau tawg
Yog tias koj txhawj xeeb tias tib neeg (piv txwv li, phooj ywg lossis niam txiv) yuav sim ua kom tawg koj tus cipher, tsis txhob txwv koj tus kheej tsuas yog siv cov ntawv nkaus xwb. Qhia qee cov cim rau koj tus cipher. Txoj hauv kev no, cov lus nkag yuav suav nrog cov cim cim cim cim thiab tsis yog cov tsiaj ntawv, ua rau lawv nkag siab ntau dua rau cov tib neeg yam tsis muaj tus lej zais. Piv txwv li, koj tus lej encryption nrog cov cim tuaj yeem nyeem:
- A B C D E F G H I J K L M N O P Q R S T U V W X Y Z.
- X Y Z & B C D E # G H I J K $ M N O P Q R @ T U = W.
- Siv tus lej no, cov lus "YUAV UA LI CAS KOJ" yuav nyeem "E $ T XOB = $ R."
- Yog tias qhov no yog koj thawj zaug tsim (lossis siv) tus lej hloov pauv, koj yuav xav hla cov kauj ruam no.
Ntu 3 ntawm 3: Kev Nkag Nkag thiab Kev Nkag Siab Cov Lus
Kauj Ruam 1. Xaiv lo lus lossis kab lus kom nkag siab
Ua ntej koj tuaj yeem tsim cov lus encrypted, koj yuav xav tau cov ntawv los nkag. Yog tias qhov no yog thawj zaug koj nkag siab cov lus siv qhov hloov pauv tus lej, pib yooj yim. Xaiv cov lus luv lossis 2 los nkag, tsis yog kab lus ntev. Piv txwv, sim kab lus "qhib qhov rooj."
- Thaum koj paub nrog txheej txheem encryption, pib nkag siab cov kab lus lossis kab lus ntev dua.
- Cov vev xaib encrypt hauv online tuaj yeem ua kom nkag siab tag nrho cov kab lus yooj yim dua.
Kauj Ruam 2. Hloov txhua tsab ntawv hauv theem nrog ib tsab ntawv los ntawm cov tsiaj ntawv cipher
Mus los ntawm koj cov kab lus Askiv lossis kab lus los ntawm tsab ntawv thiab hloov tsab ntawv Askiv nrog tsab ntawv sib xws los ntawm koj lub ntsiab lus. Nrhiav cov ntawv hloov pauv los ntawm kev txheeb xyuas tsab ntawv Askiv, tom qab ntawd saib hauv qab nws kom pom cov ntawv sib thooj hauv kab lus
Piv txwv li, hais tias koj tab tom siv tus lej nkag uas koj tau hloov pauv txhua tsab ntawv ntawm tus niam ntawv los ntawm tsab ntawv 3 ua ntej nws. Cov kab lus Askiv "QHIA QHOV TSEEB" thaum nkag rau hauv koj lub ntsiab lus yuav nyeem: "LMBK ALLO."
Kauj Ruam 3. Decrypt a coded message by finding the substitute for cipher letters
Txhawm rau txhais cov lus xa rov qab ua lus Askiv, thim rov qab cov txheej txheem uas koj siv los sau cov lus. Rau txhua tsab ntawv ntawm cov lus sib tham hauv tus ntawv ciphertext, nrhiav tsab ntawv nws sib haum rau hauv cov ntawv Askiv. Sau tawm txhua tsab ntawv 1 ntawm ib lub sij hawm los txiav txim siab cov lus.
Piv txwv li, cia peb hais tias koj tseem tab tom siv cov ntawv ciphertext uas hloov tus qauv ntawv niam ntawv nrog tus ntawv 3 ua ntej lawv. Yog tias koj tus phooj ywg hla koj tus lej uas nyeem "ZLLI EXQ. IRKZE PLLK?” koj tuaj yeem siv tus tsiaj ntawv cipher los txiav txim siab nws. Koj yuav pom tias cov lus hais tias "COOL HAT. Noj su ntev?”
Lub tswv yim
- Muaj ntau ntau lwm qhov kev hloov pauv ciphers uas twb muaj lawm uas koj tuaj yeem pib koj li cipher tshiab uas tsim los. Yog tias koj xav tau, sim siv ib qho ntawm cov ciphers uas paub zoo dua. Cov no suav nrog CrissCross code, Nihilist Number Code, thiab Key-Word (lossis Key-Number) Code.
- Yog tias koj txhawj xeeb tias lwm tus (piv txwv li, nosy nus muag) tuaj yeem pom daim ntawv uas koj tau sau koj cov lej sib dhos, koj tuaj yeem cim ntu ua ntu zus.
- Koj tuaj yeem tsim tus lej hloov pauv rau txhua yam lus uas siv cov ntawv Latin. Thaum txhua qhov piv txwv hauv kab lus no ua lus Askiv, koj tuaj yeem ua tus cipher siv tib lub hauv paus ntsiab lus ua lus Mev, Fabkis, German, thiab lwm yam.
