Faira encryption

File Encryption unokubvumira kuwedzera imwe marongera unodzivirira, nokudaro achipa vimbiso yokuti faira achaverengwa chete noMusiki kwayo. Kana chinhu achasvinudzwa neimwe User, kunyange akapiwa mutariri neropafadzo, ipapo zvibereko chidzitiro kana maturo akagadzirwa vatambi vachaonekwa pamberi pake. Nemamwe mashoko, encrypted Data hazvigoni kuverenga, kana uri kushanda pane hurongwa pasi rako pachako nhoroondo. Funga ukama nyaya zvizere.

Encrypting mafaira uye folders inzira nyore chaizvo kudzivirira zvakavanzika mashoko. Asi kana unencrypted uye encrypted Data hunowanikwa pamusoro chete Disc, zvinogona kukonzera nezvimwewo zvabuda.

For Windows 7 vanoshandisa, pane chinokosha chokushandisa, yainzi BitLocker. Chikumbiro ichi kunoita zvose mashoko kubva dhisiki kupinda imwe hombe faira, rudano izvo mune ramangwana riri kwakafanana rakapotsa zvakaoma disk. Kana ukaenda kune nemunhu ari uchishandisa mamiriro ezvinhu encrypted mafaira, kuti encryption uye Decryption kwacho kunoitika muna necheseri, kureva, Hamunzwisisi. The mukana mukuru BitLocker Chirongwa ndechokuti rinopa encryption pamusoro mafaira (uye gadziriro uyewo), uye izvi zvinoita kuti zviome kuti kutsemuka pasiwedhi, uyewo kunze komutemo kuwana negadziriro kubva kunze. Kana encrypting yose nemotokari, hapana chikonzero encrypt mumwe mafaira.

Dhisiki encryption zvinokosha kuzarura peji "Drive Encryption" mupurogiramu - riri pamusoro control panel. Kana shoko sokuti kwamuri kuti TPM isina kuwanikwa, ipapo unofanira aone kana kombiyuta yako yakakodzera Bios update kuti inotsigira TPM.

TPM ari Chip iri motherboard apo BitLocker encryption kiyi, izvo rinobvumira kombiyuta kuita booting kune encrypted disk. Kana Bios haritsigiri TPM, kuti vanhuwo USB-nemotokari rakanyatsojeka inokwanisa kuti rive chip. The mushandisi hakufaniri chete tara faira sezvo vachengeterwe encryption, uye kushanda mugadziriro achaita kushanda encryption uye Decryption necheseri kana pane zvakasikwa kana kuona faira. Dzimwe nguva izvi mhando encryption zvinoshamisa kuti haawirirani kunonyanyisa kuchengeteka.

Encrypting mafaira ari kushanda ari NTFS faira hurongwa, riri rimwe faira hurongwa havatomborina kuwanika. Panoti kuti iwe vaikopera encrypted faira kuti USB nemotokari kana CD-ROM chisingazobudiswi decrypted, sezvo namano izvi havatsigiri ichi faira hurongwa.

File encryption: kutevedzana yezviito

Kana tiri kutaura pamusoro Windows 7, pano pane nyore chaizvo uye watodaro pamusoro User nezviito, zvichiita kuti vawane achida mugumisiro.

Tinofanira kutanga kururamisa-tinya achifurira inodiwa mafaira muna Windows Explorer, uye ipapo sarudza kubva akapoteredza Muterere chinhu ehupfumi. On the "General" Tab, kusarudza "Extras". Pashure manipulations izvi pahwindo kuti anovhura, unofanira kuisa chiratidzo "Encrypt mukati kundotora date". Pashure nekudzvanya "OK" kuchinja zvose zvichaitika kushanda.

Uyewo mamwe matanho, izvi zvinoreva rwakati encryption nzira. Muchiitiko ichi tiri kutaura nzira kwacho nezvokuwana encrypted mafaira. Nokuti zvinhu zvakadai zvakakodzera kushandisa cryptography kiyi, uyewo dzimwe nzira dzakawanda.

cryptography Key chinhu algorithm umo kiyi anozivikanwa chete yatumira uye wacho. Symmetric encryption anoshandisa encrypt uye decrypt kiyi chete. Asymmetric encryption ndiko kushandisa vanhu kiyi encrypt uye kuvharwa - nokuti Decryption.
