Kev xa cov lej tawm ntawm cov ntaub ntawv tshaj tawm uas siv cov software tshaj lij yuav tsum yog tib lub software los yog lub laij loj zog loj thiab cov phiaj xwm ntau dua. Txawm li cas los xij, ntau zaus, ntau cov cuab yeej siv tau yooj yim yog siv rau qhov encoding, uas yooj yim dua rau kev txiav suab ntawm.
Cov Lus Qhia

Hauv kev tsim kho hauv web, txoj hauv kev nkag siab ntawm cov ntaub ntawv encryption feem ntau siv - siv cov haujlwm tsim ntawm kev ua haujlwm ntawm hom lus. Ntawm cov server-sab lus, PHP yog feem ntau niaj hnub no, nyob rau hauv uas base64_encode kev ua haujlwm yog siv rau encryption. Cov ntaub ntawv tau tshaj tawm nrog nws cov kev pab tuaj yeem txiav txim siab los siv qhov kev rov ua dua qub - base64_decode. Yog tias koj muaj peev xwm ua tiav PHP scripts nyob rau hauv koj lub computer lossis ntawm lub web server, tsim ib txoj cai yooj yim zoo li no:
<? php
ncha base64_decode ('');
?>
Nruab nrab ntawm cov kab lus ntawm base64_decode muaj nuj nqi, tso cov hlua cov ntaub ntawv uas koj xav tau kom decrypt. Tom qab ntawv khaws cov cai rau ib daim ntawv nrog php txuas ntxiv thiab qhib nplooj ntawv no los ntawm qhov browser - hauv nplooj ntawv dawb paug koj yuav pom cov ntaub ntawv tawm.

Yog tias nws tsis tuaj yeem ua tiav php scripts, siv daim foos web ntawm ib qho ntawm Is Taws Nem is taws nem - qhov txuas mus rau nplooj ntawv yuav tsum tau muab hauv qab no. Luam tawm thiab muab kaw rau cov ntaub ntawv nkag mus rau hauv lub teb saum toj no Base 64 Decode khawm. Tom qab txhaj lub pob no, ib daim teb ntxiv nrog cov ntaub ntawv thim tawm yuav tshwm sim - lawv tuaj yeem luam thiab siv raws li koj xaiv.

Yog tias koj tsis paub txoj kev siv encryption, sim txiav suab ntawm cov ntaub ntawv uas siv ib qho ntawm cov kev pabcuam uas tuaj yeem ua kom dhau ntawm ntau lub algorithms. Ib qho ntawm cov ntawv thov no hu ua "Stirlitz", tsis tas yuav tsum teeb tsa thiab yog qhov nrov heev hauv Is Taws Nem, yog li nws yuav tsis nyuaj nrhiav nws. Qhov kev zov me nyuam sim ua decrypt cov ntaub ntawv siv tsib encryption algorithms.

Kev hloov kho tshiab tshaj tawm ntawm Windows ua rau koj tshaj tawm cov ntaub ntawv ntawm txhua qhov tsav tsheb lossis rau tag nrho cov xov xwm hauv koj lub computer. Yog tias koj xav tau txiav suab ntawm cov ntaub ntawv los ntawm cov ntaub ntawv zoo li no, nws yog qhov zoo tshaj plaws rau kev tso siab rau OS nws tus kheej - lov tes taw encryption nyob hauv nws cov chaw, thiab Windows yuav tshaj tawm tag nrho cov ntaub ntawv nrog cov ntaub ntawv hauv lawv cov unencrypted versions. Txhawm rau ua li no, nyem lub Win yeej, hom BitLocker, thiab xaiv BitLocker Drive Encryption los ntawm cov kev tshawb pom. Tom qab ntawd nyem qhov "Disable BitLocker" txuas txuas ntawm lub kaw yam. Thaum lub kaw lus tiav tiav cov lus txib no, koj tuaj yeem qhib cov ntaub ntawv nrog cov ntawv sau ua ntej.
