kev siv end-to-end encryption ntawm sab neeg siv khoom
kom ntseeg tau tias koj cov ntaub ntawv tseem nyob ntiag tug thiab muaj kev nyab xeeb.
Thaum encryption qhib lawm, tag nrho cov ntawv thiab cov duab yuav raug encrypted hauv koj tus browser ua ntej xa mus rau peb cov servers.
Qhov no txhais tau tias peb yeej tsis muaj cai nkag mus rau koj cov ntaub ntawv tsis tau encrypted lossis koj tus password.
🛡️ Koj cov ntaub ntawv raug encrypted ua ntej nws tawm ntawm koj lub cuab yeej.
Lub server tsuas yog khaws cov ntaub ntawv encrypted thiab yeej tsis pom koj tus password lossis cov ntsiab lus decrypted.

Nws Ua Haujlwm Li Cas
Cov Txheej Txheem Encryption
1
Sau Lo Lus zais
Koj muab ib lo lus zais
2
Kev Tshawb Nrhiav Tseem Ceeb
PBKDF2 tsim cov yuam sij encryption
3
Encrypt Cov Ntaub Ntawv
AES-256-GCM encrypts cov ntsiab lus
4
Upload
Cov ntaub ntawv encrypted xa mus rau lub server
Kev faib tawm cov kauj ruam:
- Kev Tsim Ntshav Random:
Ib qho ntsev tshwj xeeb 128-ntsis yog tsim rau txhua qhov kev ua haujlwm encryption
- Kev Tsim Tawm IV Random:
Ib qho tshwj xeeb 96-bit initialization vector (IV) yog tsim tawm
- Kev Tshawb Fawb Tseem Ceeb:
Koj tus password raug muab ua ke nrog ntsev siv PBKDF2 nrog 100,000 qhov rov ua dua los tsim kom muaj tus yuam sij encryption 256-ntsis muaj zog.
- Kev zais cia:
Cov ntaub ntawv raug encrypted siv AES-256-GCM nrog tus yuam sij thiab IV uas tau los ntawm
- Cov Ntaub Ntawv Ntim:
Cov ntsev, IV, thiab cov ntaub ntawv encrypted tau muab tso ua ke thiab encoded hauv Base64
- Upload:
Tsuas yog cov pob khoom encrypted thiaj li raug xa mus rau lub server xwb
Cov Txheej Txheem Decryption
Thaum koj lossis ib tus neeg uas muaj lo lus zais qhib ib qho channel uas tau encrypted:
- Kev Sau Lo Lus Zais:
Yuav tsum muab tus password kom raug
- Rub Tawm Cov Ntaub Ntawv:
Cov ntaub ntawv encrypted raug rub tawm los ntawm lub server
- Kev rho tawm:
Ntshav thiab IV raug rho tawm ntawm lub pob khoom encrypted
- Kev Tshawb Fawb Tseem Ceeb:
Cov txheej txheem PBKDF2 tib yam rov tsim dua tus yuam sij encryption los ntawm tus password thiab ntsev
- Kev txhais lus:
AES-256-GCM decrypts cov ntaub ntawv siv tus yuam sij thiab IV uas tau txais los.
- Zaub:
Cov ntsiab lus decrypted tau tso tawm hauv koj tus browser
Cov Nta Kev Ruaj Ntseg
🔒 Kev Siv Encryption Sab Neeg Siv Khoom
Txhua qhov kev encryption thiab decryption tshwm sim hauv koj tus browser siv Web Crypto API. Koj tus password thiab cov ntaub ntawv tsis tau encrypted yeej tsis tawm ntawm koj lub cuab yeej.
🎲 Kev Siv Encryption Tshwj Xeeb Rau Ib Zaug Ua Haujlwm
Txhua zaus cov ntaub ntawv raug encrypted, cov nqi ntsev tshiab thiab IV raug tsim tawm. Qhov no txhais tau tias cov ntsiab lus tib yam uas encrypted ob zaug tsim cov ntawv ciphertext sib txawv kiag li, tiv thaiv kev tshuaj xyuas tus qauv.
🔐 Kev Siv Tus yuam sij muaj zog
PBKDF2 nrog 100,000 qhov rov ua dua ua rau kev tawm tsam lo lus zais brute-force kim heev. Txawm tias muaj lo lus zais muaj zog nruab nrab, cov neeg tawm tsam yuav xav tau cov peev txheej tseem ceeb los rhuav tshem qhov encryption.
✅ Kev lees paub encrypted
AES-GCM muab ob qho tib si kev ceev ntiag tug thiab qhov tseeb. Nws ua kom ntseeg tau tias cov ntaub ntawv encrypted tsis tau raug cuam tshuam, tiv thaiv kev tawm tsam hloov kho.
🌐 Cov Algorithms Txheem Kev Lag Luam
Peb tsuas yog siv cov algorithms cryptographic uas tau tsim zoo, thiab tau tshuaj xyuas los ntawm cov phooj ywg (AES-256, PBKDF2, SHA-256) uas cov kws tshaj lij kev ruaj ntseg thoob ntiaj teb ntseeg siab.
