File storage encryption tsuas yog qhov encryption ntawm cov ntaub ntawv khaws cia, feem ntau yog rau lub hom phiaj ntawm kev tiv thaiv cov ntaub ntawv rhiab los ntawm kev saib los ntawm cov neeg uas tsis tuaj yeem nkag mus rau nws.

Encryption tso cov ntaub ntawv rau hauv lo lus zais tiv thaiv thiab scrambled hom hu ua ciphertext uas tsis yog tib neeg-nyeem tau, thiab yog li tsis tuaj yeem nkag siab yam tsis tau ua ntej decrypting lawv rov qab rau hauv lub xeev uas nyeem tau yooj yim hu ua plaintext, lossis cleartext.

Cov ntaub ntawv khaws cia encryption txawv dua li cov ntaub ntawv hloov pauv encryption, uas yog encryption siv nkaus xwb thaum tsiv cov ntaub ntawv los ntawm ib qho mus rau lwm qhov.

Thaum twg Yog Cov Ntaub Ntawv Cia Encryption siv?

Cov ntaub ntawv khaws cia encryption yuav siv tau ntau dua yog tias cov ntaub ntawv khaws cia hauv online lossis hauv qhov chaw nkag tau yooj yim, xws li ntawm tus tsav sab nraud lossis flash drive.

Txhua daim software tuaj yeem siv cov ntaub ntawv khaws cia encryption, tab sis nws ib txwm muaj txiaj ntsig zoo tsuas yog khaws cov ntaub ntawv tus kheej xwb.

Rau cov kev pab cuam uas tsis muaj encryption built-in, cov cuab yeej thib peb tuaj yeem ua haujlwm. Piv txwv li, ib tug xov tooj ntawm dawb, tag nrho disk encryption cov kev pab cuam tawm muaj uas yuav siv tau los encrypt ib tug tag nrho tsav. Qee zaum, qhov kev zov me nyuam ntxiv cov ntaub ntawv tshwj xeeb txuas ntxiv mus rau qhov kawg ntawm cov ntaub ntawv npe los xaiv nws ua cov ntaub ntawv encrypted-AXX, KEY, CHA, EPM, thiab ENCRYPTED yog ob peb yam piv txwv.

Nws yog ib qho uas encryption siv los ntawm cov tuam txhab ntawm lawv tus kheej servers thaum koj cov ntaub ntawv ntiag tug xws li cov ntaub ntawv them nyiaj, duab, email, lossis cov ntaub ntawv qhov chaw raug khaws cia.

Cov Ntaub Ntawv Cia Encryption Me ntsis

AES encryption algorithm muaj nyob rau hauv ntau yam sib txawv: 128-ntsis, 192-ntsis, thiab 256-ntsis. Tus nqi me ntsis siab dua yuav muab kev ruaj ntseg ntau dua li qhov me dua, tab sis rau cov hom phiaj siv tau, txawm tias qhov kev xaiv 128-ntsis encryption yog qhov txaus rau kev tiv thaiv cov ntaub ntawv digital.

Blowfish yog lwm qhov muaj zog encryption algorithm uas yuav siv tau los khaws cov ntaub ntawv kom ruaj ntseg. Nws siv qhov ntev tseem ceeb nyob qhov twg los ntawm 32 ntsis txog 448 ntsis.

Qhov sib txawv loj ntawm cov nqi me me no yog qhov ntev ntawm qhov tseem ceeb siv ntau qhov sib tw dua li cov me me. Piv txwv li, 128-ntsis encryption siv 10 rounds thaum 256-ntsis encryption siv 14 rounds, thiab Blowfish siv 16. Yog li, plaub los yog rau rau ntau rounds yog siv nyob rau hauv qhov ntev tseem ceeb qhov ntau thiab tsawg, uas txhais mus rau repetitions ntxiv nyob rau hauv converting plaintext rau ciphertext.. Qhov ntau repetitions uas tshwm sim, ntau jumbled cov ntaub ntawv ua, ua rau nws nyuaj rau tawg.

Txawm li cas los xij, txawm tias 128-ntsis encryption tsis rov ua lub voj voog ntau zaus raws li lwm cov nqi me ntsis, nws tseem muaj kev nyab xeeb heev, thiab yuav siv sij hawm ntau lub zog ua haujlwm thiab ntau lub sijhawm los rhuav tshem. niaj hnub technology.

Cov Ntaub Ntawv Cia Encryption Nrog Cov Ntaub Ntawv Rov Qab

Ze li txhua qhov kev pabcuam thaub qab online siv cov ntaub ntawv khaws cia encryption. Qhov no yog qhov tsim nyog los txiav txim siab tias cov ntaub ntawv ntiag tug xws li cov yeeb yaj kiab, duab, thiab cov ntaub ntawv raug muab khaws cia rau ntawm cov servers uas nkag tau hauv internet.

Ib zaug encrypted, cov ntaub ntawv tsis tuaj yeem nyeem los ntawm ib tus neeg tshwj tsis yog tias tus password siv los encrypt nws yog tom qab siv rov qab qhov encryption, lossis decrypt nws, tso cai rau koj cov ntaub ntawv.

Qee ib txwm, offline backup cov cuab yeej kuj siv cov ntaub ntawv khaws cia encryption kom cov ntaub ntawv koj rov qab mus rau lub portable drive, zoo li lwm lub hard drive, disc, lossis flash drive, tsis nyob rau hauv daim ntawv uas leej twg muaj. ntawm tus tsav tuaj yeem saib.

Hauv qhov no, zoo ib yam li thaub qab online, cov ntaub ntawv tsis tuaj yeem nyeem tau tshwj tsis yog tib lub software, nrog rau tus password decryption, yog siv los xa cov ntaub ntawv rov qab rau hauv cov ntawv dawb.
