Cov ntaub ntawv encryption

Cov ntaub ntawv Encryption tso cai rau koj mus ntxiv lwm txheej ntawm kev tiv thaiv, li no muab lub siab hais tias cov ntaub ntawv yuav tsum tau nyeem nkaus xwb los ntawm nws cov creator. Yog hais tias tus kwv yuav tsum qhib los ntawm lwm yam kev siv, txawm muab tej txiaj ntsim nrog cov thawj coj tsim nyog, ces ib tug dawb paug screen los yog ib tug meaningless set ntawm cov cim yuav tshwm sim nyob rau hauv pem hauv ntej ntawm nws. Nyob rau hauv lwm yam lus, lub encrypted cov ntaub ntawv yuav tsis tsum nyeem, tshwj tsis yog tias koj yog ua hauj lwm rau ib tug system nyob rau hauv koj tus kheej account. Xav txog txog cov teeb meem nyob rau hauv ntau yam.

Encrypting ntaub ntawv thiab folders yog ib tug heev yooj yim txoj kev ntawm kev tiv thaiv ntaub ntawv. Tiam sis yog tias unencrypted thiab encrypted ntaub ntawv yuav raug khaws tseg rau ib tug tib disc, tej zaum nws yuav ua rau unpredictable tau.

Rau lub qhov rais 7 cov neeg siv, muaj ib tug tshwj xeeb lub cuab tam, uas yog hu ua BitLocker. Daim ntawv thov no tsiv tag nrho ntawm cov ntaub ntawv los ntawm lub disk rau hauv ib tug loj heev cov ntaub ntawv, ib tug hu uas nyob rau hauv lub neej yav tom ntej yog tib yam li cov virtual hard disk. Yog hais tias koj mus rau ib tug neeg xyuas pib ntawm lub operating system rau encrypted ntaub ntawv, cov encryption thiab decryption txheej txheem tshwm sim nyob rau hauv lub keeb kwm yav dhau, hais tias yog, koj tsis paub. Qhov zoo kom zoo dua ntawm BitLocker kev pab cuam yog hais tias nws muaj encryption ntawm cov ntaub ntawv (thiab system zoo li), thiab qhov no yuav ua rau nws nyuaj rau keej lo lus zais, raws li zoo raws li tsis tau tso cai nkag tau mus rau lub system ntawm sab nraum. Yog hais tias encrypting tag nrho tsav, yog tsis muaj yuav tsum tau encrypt neeg cov ntaub ntawv.

Disk encryption yog tsim nyog yuav tau qhib qhov page "Drive Encryption" nyob rau hauv qhov kev pab cuam - nws yog nyob rau hauv cov kev tswj vaj huam sib luag. Yog hais tias cov lus zoo nkaus li rau koj hais tias lub TPM yog tsis pom, ces koj yuav tsum mus xyuas seb koj lub computer rau cov tsim nyog BIOS update uas txhawb nqa TPM.

TPM yog ib tug nti nyob rau hauv lub motherboard qhov twg lub BitLocker encryption qhov tseem ceeb, uas tso cai rau lub computer ua booting los ntawm ib tug encrypted disk. Yog hais tias lub BIOS tsis txhawb TPM, qhov dog dig USB-tsav yog heev muaj peev xwm mus ua hauj lwm raws li ib tug nti. Tus neeg siv yuav tsum tsuas kos tus cim rau cov ntaub ntawv raws li nyob rau encryption, thiab cov kev khiav hauj lwm qhov system yuav ua lub lag luam ntawm encryption thiab decryption nyob rau hauv lub keeb kwm yav dhau thaum muaj ib tug creation, los yog saib cov ntaub ntawv. Tej zaum qhov no hom ntawm encryption surprises uas yog incompatible nrog lub siab tshaj plaws kev ruaj ntseg.

Encrypting cov ntaub ntawv yog ib tug muaj nuj nqi ntawm lub NTFS ntaub ntawv kaw lus, uas yog nyob rau hauv lub lwm yam ntaub ntawv systems tsuas tsis muaj. Nws hais tias koj tau theej lub encrypted ntaub ntawv mus rau ib tug USB tsav los yog CD-ROM yuav tsis tau decrypted, vim tej no pab kiag li lawm tsis txhawb cov ntaub ntawv no system.

Cov ntaub ntawv encryption: ib theem zuj zus ntawm kev ua

Yog hais tias peb yuav sib tham txog qhov rais 7, ntawm no yog ib tug heev yooj yim thiab cov zajlus kom ib theem zuj zus ntawm cov neeg siv kev ua, uas peb txais tau cov kev kawm no.

Ua ntej peb yuav tsum txoj-nias rau ntawm lub ntxias uas yuav tsum tau cov ntaub ntawv nyob rau hauv lub qhov rais Explorer, thiab ces xaiv los ntawm lub ntsiab lus teb ntawv qhia zaub mov khoom zog. Nyob rau hauv "General" tab, xaiv cov "Riam". Tom qab no manipulations nyob rau hauv lub qhov rais uas qhib, koj yuav tau teem lub cim "Encrypt txheem kom ruaj ntseg cov ntaub ntawv". Tom qab txhaj "OK" tag nrho cov kev hloov yuav siv tau.

Raws li zoo raws li lwm yam kev ua, qhov no implies ib co kev encryption txoj kev. Nyob rau hauv cov ntaub ntawv no peb yuav tham txog qhov mus kom ze rau txoj kev txais lub encrypted ntaub ntawv. Rau xws li cov khoom tsim nyog siv cryptography tseem ceeb, raws li zoo li ob peb lwm txoj kev.

Ntsiab cryptography yog ib qho algorithm nyob rau hauv uas tus yuam sij yog paub tsuas mus rau cov sender thiab cov neeg tau kev pab. Yam encryption siv los encrypt thiab decrypt tib qhov tseem ceeb. Asymmetric encryption yog siv cov pej xeem tseem ceeb rau encrypt thiab kaw - rau decryption.
