Dzimwe nguva, isu tinofanirwa kunyorera zvakavanzika kwazvo data pane edu masystem kuitira kuti pasave neumwe munhu anoshandisa system yedu angati takanyima ruzivo.
Imwe nzira yekuita izvi ndeyekuvanza mafaira akavanzika uye mameseji mukati memamwe mafaera aripo, semifananidzo uye odhiyo.
Izvi futi inobatsira kwazvo kana iwe uchida kuendesa yakavanzika meseji kana kutumira faira pamusoro penetiweki kune mumwe munhu usingakanganisi kuchengetedzeka kwako.
Ivo vanogona kungoisa iyo yakavanzika dhata, pamwe ne password kana passkey kuitira kuti chete munhu akavimbika munhu anogona kuvhura iyo faira.
Rudzi urwu rwekunyorera kwaunonyatsovanza imwe faira mune imwe inonzi steganography..
Steganography inosarudzwa pane cryptography nekuti gare gare mhandu anozoziva kuti chimwe chinhu chaive chakavanzika mune chinyorwa kana faira. Ivo vanogona kunyange kutyora kodhi uye kuwana ruzivo kuburikidza nekushanda nesimba.
Mune Steganography, zvakadaro, munhu wechitatu haatomboziva nezve icho chinoratidzika kunge chisina kukuvadza mufananidzo kana odhiyo faira rinotakura rakavanzika meseji kana faira rakadzika mukati maro.
Kuisa Steghide paUbuntu 18.10 uye zvigadzirwa
Steghide iri rairo yekushandisa iyo inokutendera iwe kuti uvanze zvakavanzika dhata mukati memhando dzakasiyana dzemifananidzo uye odhiyo mafaera.
Steghide inoshanda kubva kunyaradzo paWindows uye GNU / Linux, uye iri rakavhurika sosi purojekiti iyo inongobata inenge 3Mb isina kuvhurwa, uye haidi kuisirwa, saka inogona kushandiswa pamapendrives.
Kunyangwe mune ino kesi isu tichaenda kuisa yazvino vhezheni yeichi chishandiso, Unogona kuzviita nekuitsvaga yakanangana neUbuntu software Center kana kubva kumagumo iwe unogona kuzviita nekuita unotevera kuraira:
sudo apt-get install steghide
Faira encryption ne steghide
Kuti vanyore faira rakavanzika faira, vanofanirwa kuve nefaira ravanoda kunyorera uye mufananidzo kana odhiyo faira mavanoda kuriviga.
Steghide inotsigira kunyorera pane AU, BMP, JPEG, uye WAV faira mhando.
Iye zvino kutora muenzaniso isu tinoda kuviga faira mukati memufananidzo. Mutsara watinofanira kushandisa unotevera:
sudo steghide embed -ef examplefile.txt -cf sample.jpg
Mune ino kesi isu tiri kuratidza kuti iyo faira inofanirwa kuverengerwa kubva pane yazvino folda kuenda kune yazvino folda.
Kana iri faira rekuvanzika rakawanikwa kumwe kunzira yako, vanofanirwa kupa nzira yakazara.
Saizvozvo, kana yako faira refaira iri kune imwe nzvimbo, unofanirwa kudoma nzira yayo izere kuburikidza nemurairo uyu.
Chaizvoizvo iwo murairo unonyorwa seinotevera:
sudo steghide embed -ef /ruta/de/archivo/a/ocultar -cf /ruta/de/imagen/o/audio/que/contendrá/el/archivo
Pakarepo mushure meizvi, iko kunyorera kunozokumbira password inodiwa kuti isimbise yakavanzika faira.
Iri password ndiro rinoshandiswa kuburitsa kana kutsikisa faira.
Mumuenzaniso uyu, isu takaburitsa faira refaira mufaira reJPEG. Mushure mekunyorwa kwekunyora, unogona kudzima rako rekuvanzika faira uye chengeta iyo faira refaira iro richazoshandiswa kubisa.
Kubvisa faira
Iye zvino kubvisa ruzivo rwakavanzwa mukati mefaira, tiri kuzoshandisa rairo rinotevera
sudo steghide -sf image.jpg
Kwatinoratidza nzira yemufananidzo kana odhiyo faira iro rine ruzivo rwedu rwakavanzika, kana tichiita izvi tinokumbirwa kuti tipe passwordKuita izvi kuchaburitsa ruzivo rwatinovanza mukati memafaira.
Maitiro ekubvisa Steghide kubva kuUbuntu uye zvigadzirwa?
Chekupedzisira, kune avo vasina kugutsikana nechishandiso kana kungoda kuibvisa kubva kuhurongwa hwavo, tinogona kutora nhanho inotevera kuitira kuti Steghide ibviswe zvachose.
Tinofanira kuvhura terminal neCtrl + Alt + T uye mairi tichaita unotevera kuraira:
sudo apt-get remove steghide
Uye wakagadzirira.
Sekutaura kwekupedzisira, tinogona kushandisa Steghide pamwe nemamwe maturusi akadai se Cryptomator uye kunyangwe OnionShare kukwanisa kugovera ruzivo mukati memafaira edu nevamwe vanhu nenzira yakachengeteka.
