Encryption file

Sirta File kuu ogolaanaya in aad ku dari lakabka kale oo ilaalin ah, oon ku siinaya hubaasha in file loo akhriyi doonaa oo kaliya ay abuure. Haddii wax laga furi doonaa by user kasta oo kale, xitaa caqliga leh mudnaanta maamulka, markaas screen maran ama go'an waxba tarayn jilayaasha muuqan doona isaga ka soo hor. In si kale loo dhigo, ka data sir aan la akhriyi kartaa, haddii aad ka shaqeeya nidaam hoos xisaabtaada shakhsiyeed. Tixgeli arrimaha la xiriira si faahfaahsan.

Imayladad, files iyo fayl waa hab aad u sahlan ee ilaalinta macluumaad qarsoodi ah. Laakiin haddii xogta baraha iyo Windows XP lagu kaydin doonaa hal disc a, waxa ay keeni kartaa natiijo aan la saadaalin karin.

Waayo, Windows 7 isticmaala, waxaa jira qalab gaar ah, oo la yidhaahdo BitLocker. Codsigan guuro dhammaan macluumaadka ka disk galay mid ka mid ah file weyn, call a kaas oo mustaqbalka waa isku mid sida disk ee dalwaddii adag. Haddii aad tagto kaari ah nidaamka qalliinka in files-lo, nidaamka encryption iyo decryption ku dhacdaa asalka, in uu yahay, idinkoon ogayn. Faa'iidada weyn ee barnaamijka BitLocker waa in ay bixisaa encryption of files (iyo nidaamka iyo sidoo), iyo taas oo ka dhigaysa adag tahay in crack password, iyo sidoo kale helitaanka aan la ogolayn in nidaamka ka baxsan ka. Haddii imayl drive oo dhan, aan loo baahnayn in sir files shaqsi.

encryption disk waxaa lagama maarmaan ah in la furo bogga "Drive sirta" barnaamijka - waxa uu ku yaalaa on guddi ay gacanta ku. Haddii fariin u muuqataa in aad in TPM la helin, ka dibna aad u baahan tahay si aad u hubiso in aad computer ah ee ku haboon update BIOS taageera TPM.

TPM waa chip ku yaal on motherboard meesha muhiimka ah ee sirta ah BitLocker, kaas oo u ogolaanaya computer ka si ay u qabtaan computerka guud ahaan ka disk ah lo. Haddii BIOS ah ma taageeri TPM, ee USB-drive caadiga ah waa wax awood inuu kuugu adeego sidii jab ah. user The calaamadee baahan kaliya faylka sida oo lagu qabtay sirta ah, iyo nidaamka ka hawlgala dhigi doonaa howlgalka of sirta iyo decryption ee asalka ah marka uu jiro waa abuur ah, ama u argto faylka. Mararka qaarkood noocan ah wax kadis ah encryption in ay yihiin in aynan nabadgelyada ugu badnaan.

Imayladad files waa shaqo ah nidaamka file NTFS ah, taas oo ah in hababka kale ee file si fudud waxaa laga heli karaa ma. Wuxu leeyahay in aad soo guuriyeen faylka lo si drive USB ama CD-ROM aan la decrypted, tan iyo qalabka ma taageeraan nidaamka file this.

File encryption: isku xigxiga oo ka mid ah tallaabooyinka

Haddii aynu ka hadlayno Windows 7, halkan waxaa jira isku xigxiga oo aad u fudud oo macquul ah ee falalka user, noo ogolaaday in la helo natiijada la rabay.

Marka hore waxaan u baahan tahay inaad midig-riix files manipulator loo baahan yahay in Windows Explorer, ka dibna dooro ka mid ah guryaha wax macno menu. On the "Guud" tab, dooro "Extras". Ka dib markii kuwan manipulations furmo in furay, waa in aad dhigay sumaddii "waxyaabaha sir si loo sugo xogta". Ka dib markii riixaya "OK" dhammaan isbeddellada dhaqan-gali doona.

Iyo sidoo kale wax talaabo ah oo kale, taas oo muujinaysa qaar ka mid ah hababka sirta gaar ah. Xaaladdan oo kale waxaan ka hadleynaa hab si hannaanka lagu helo faylasha lo. Waayo, waxyaabaha sida ku haboon si ay u isticmaalaan key cryptography, iyo sidoo kale dhowr ah hababka kale.

cryptography Key waa isku geynta ah kaas oo fure u ah waxa loo yaqaan oo kaliya in ay ka diraha iyo qaataha. encryption Symmetric isticmaasho si sir iyo decrypt fure isku mid ah. encryption sinnayn waa in ay isticmaalaan furaha dadweynaha si sir iyo la xiray - waayo decryption.
