Tag nrho cov software ntawm txhua lub khoos phis tawm niaj hnub sau raws li lub tswv yim ntawm cov ntawv coding. Tag nrho cov txheej txheem hauv Is Taws Nem kuj muaj feem cuam txuam nrog cov cim txheej txheem; txhua cov xov xwm digital yog cov binary code. Encoding kuj tseem ua tiav siv nyob rau hauv tus txheej txheem ntawm kev tiv thaiv cov ntaub ntawv, cov ntaub ntawv ib leeg hauv Is Taws Nem.
Tsim nyog
- - Cov kev txawj programming;
- - ib qhov kev pab cuam zoo li Crypditor.
Cov Lus Qhia

Khaws cov ntaub ntawv tsis raug kaw ntawm tus neeg rau zaub mov tuaj yeem ua rau kom tsis muaj cov ntaub ntawv tsis txaus ntseeg, tshwj xeeb - cov yuam sij rau lub chaw khaws ntaub ntawv lossis, piv txwv li, qee daim ntawv tseem ceeb. Yog li ntawd, nws yog qhov zoo dua rau kev nkag rau cov ntaub ntawv txhua yam ua ntej, i.e. encode. Muaj ntau ntau cov kev pab cuam uas tuaj yeem pab koj tiv thaiv cov ntaub ntawv koj xav tau, tab sis ntau ntawm lawv tsis tuaj yeem ntseeg lossis them nyiaj. Ntau cov ntaub ntawv tuaj yeem tiv thaiv siv cov txheej txheem PHP txheem. Lub hauv paus ua haujlwm base64_encode () tsim nyog rau qhov no. Rau rov qab txiav txim siab, feem, base64_decode () yog siv. Kuj tseem muaj cov algorithms md5 () thiab sha1 (), tab sis lawv yuav luag tsis paub txog. PHP kuj siv JSON encoding. Nws tso cai rau koj los sau cov ntaub ntawv hauv cov ntaub ntawv tshwj xeeb cov ntaub ntawv thiab muaj daim ntawv json_encode ($ array). Txog kev txiav txim siab, ntu, json_decode ($ array). Los encode cov ntaub ntawv kis ntawm cov ntaub ntawv, koj tuaj yeem siv tus txheej txheem crypt (). Nws encrypts cov ntaub ntawv hauv ib qho kev taw qhia. Qhov zoo ntawm cov yam ntxwv no yog tias nws tso cai rau koj los ntawm koj tus kheej txoj cai.
Kauj ruam 2
Siv Java Script, koj tuaj yeem yooj yim encode qee cov ntaub ntawv duab. Muaj ib lub javascript: imageData muaj nuj nqi rau qhov no. Kuj tseem muaj ib hom URI algorithm uas tuaj yeem muab nws tus kheej lub cim rau txhua yam. URI muaj cov lus cim: "URI = URL + URN URL =: // URN =".
Kauj ruam 3
Txhawm rau zais lo lus zais los ntawm ib qho peev txheej, lossis txawm los ntawm lub khoos phis tawm, koj tuaj yeem siv Cryptditor program, uas siv AES encryption algorithm. Ntxiv mus, qhov program no tso cai rau koj txheeb xyuas lub zog ntawm cov lej password uas siv ua ntej lawv nkag mus.
