Ukubethelwa kwedatha isilinganiso kudingekile ukuvikela idatha yakho

Ukubethelwa kwedatha - indlela ukufihla umqondo wokuqala noma umyalezo idokhumenti, esihlinzeka ukuhlanekezela ifomu yayo yasekuqaleni. Ngamagama alula, kuba indlela ukuvikela ulwazi. Le nqubo ibizwa ngokuthi futhi code njengoba usebenzisa isofthiwe ekhethekile noma ngesandla idluliselwe umbhalo wakho engaqondakali ikhodi ukhishwa inyumbazane. Inqubo ngokwaso luncike ukulandelana izinguquko uhlobo idatha. ukulandelana okunjalo kwezinkolo kubizwa ngokuthi i-algorithm.

Ukubethelwa kwedatha libhekisela indlela yokubhala efihla incazelo. Lokhu isayensi wenziwa uzifunde ngokucophelela izwe bezobunhloli, futhi nsuku zonke ukuxazulula futhi ukudala ama-algorithms entsha cryptographic.

izindlela ukubethela bebelokhu baziwa kusukela ezikhathini zasendulo, lapho ujenene ongumRoma wadlulela izithunywa imilayezo ebalulekile ifomu ngekhodi. I-algorithm ke zazingaphucukile, kodwa ngempumelelo udidekile izitha.

Ngokungafani nalabo izikhathi asibona abalawuli bamabutho kodwa izitha kufanele. Ziyakwazi abaculi abazimisele ukuthola idatha ebalulekile kithi. Nansi into yabo kumele avikelwe nganoma iyiphi indlela.

manje USB flash drive isibe Igumbi ethandwa kakhulu kolwazi. Ngisho corporations omkhulu ukudlula ezibalulekile, idatha oluyimfihlo kule yobuchwepheshe. funa Fleshok kuye kwaholela ososayensi ukuba ukuvikeleka kwemininingwane kubo. Ngenxa yale njongo abangu basungula uhlelo, okuyinto encrypts ulwazi on esiphathiswa usebenzisa ukhiye eyimfihlo eyaziwa kuphela kumnikazi samanje. Lokhu ngemfihlo idatha kwi drive flash ezithembeke kakhulu futhi kuzosiza ukuvikela imininingwane ebucayi emehlweni prying.

Ethandwa kakhulu ukubethela uhlelo izazi zikholelwa TrueCrypt.Ona yasungulwa ngesisekelo E4M (Ukubethela ngokuba amaMisa), inguqulo yokuqala eyakhishwa ngo-1997. Umbhali ukholelwa engumFulentshi uPawulu Rocks. Namuhla, lolu hlelo isetshenziswa izigidi zabantu futhi eziningi izinkampani ukuze kuvikelwe ukwaziswa.

Ngaphezu ukuvikela idatha ku abezindaba flash, abaningi nakho nesithakazelo disk ukubethela. Phela, abantu ngokuvamile abafuni "fihla" noma yimaphi amadokhumenti emehlweni prying. Imibuzo in izinjini sisekele lokhu, ngakho izinkampani eziningi ziye usuqalile ukuzakhela izinhlelo ezikhethekile. Namuhla kukhona izinhlelo eziningi ezahlukene ukuthi ukubhekana ukubethelwa kwedatha. Basebenzisa ezihlukahlukene algorithm cryptographic, futhi elalidume kunawo wonke - Des, AES, Ezinonya Force nabanye.

Ukubethelwa kwedatha Asigcini ukuvikela ulwazi, izenzo futhi njengoba "constrictor". archivers abaningi ugcine sediski ukusebenzisa ukubethela. Ngokwesibonelo, laziwe kubo bonke WinRAR isebenzisa ukubethela algorithm AES nge ubude ukhiye - 128. Abantu abaningi abasebenzisa ukugcina idatha kwikhompyutha yakho kuphela zomlando, futhi ifayela ngalinye sivikelwe ngephasiwedi. Uqinisekisa kubo isikhala hhayi kuphela, kodwa futhi ukuvikela ulwazi ezibucayi kusuka nabakhwabanisi.

With ukuthuthukiswa hacker Inthanethi ukulungele yini yako iwufanele ngempela enkingeni Hack kwikhompuyutha olungavikelekile kanye uthole ulwazi akudingayo. Ngakho-ke, ochwepheshe batusa ukubethela yonke idatha yakho ezibalulekile.
