Ngamanye amaxesha kufuneka sibethele idatha eyimfihlo kakhulu kwiinkqubo zethu ukuze kungabikho omnye umntu osebenzisa inkqubo yethu onokuthi siye sabamba ulwazi.
Enye indlela yokwenza oku kukufihla iifayile eziyimfihlo kunye nemiyalezo ngaphakathi kwezinye iifayile ezikhoyo, njengemifanekiso kunye nokulalelwayo.
Oku nako iluncedo kakhulu xa ufuna ukuthumela umyalezo wangasese okanye ukuthumela ifayile kwinethiwekhi komnye umntu ngaphandle kokubeka esichengeni ukhuseleko lwakho.
Banokufaka ngokulula idatha eyimfihlo, kunye negama eligqithisiweyo okanye isitshixo ukuze kuphela ngumntu othembekileyo onokuvula le fayile.
Olu hlobo lwe-encryption apho ufihla ngokukhuselekileyo ifayile enye kwenye ibizwa ngokuba yi-steganography..
I-Steganography ikhethwa ngaphezu kokubhaliweyo kuba kamva umchasi uya kwazi ukuba kukho into efihliweyo kwisicatshulwa okanye kwifayile. Banokuphula ikhowudi kwaye bafumane ulwazi ngokusebenza nzima.
Kwi-Steganography, nangona kunjalo, umntu wesithathu ngekhe ayazi into yokuba umfanekiso obonakala ungenabungozi okanye ifayile yeaudiyo inomyalezo ofihlakeleyo okanye ifayile efakwe kuwo.
Ukufaka iSteghide kwi-Ubuntu 18.10 kunye neziphumo
I-Steghide sisixhobo somgca wokuyalela esikuvumela ukuba ufihle idatha eyimfihlo kwiindidi ezahlukeneyo zomfanekiso kunye neefayile ezimanyelwayo.
Steghide isebenza kwiConsole kwiWindows nakwiGNU / Linux, kwaye yiprojekhthi yemithombo evulekileyo ehlala kuphela malunga ne-3Mb engafakwanga uziphu, kwaye ayifuni kufakwa, ukuze isetyenziswe kwiipendrives
Nangona kule meko siza kufaka ingxelo yokugqibela yesi sixhobo, Banokukwenza ngokukhangela ngqo kwiziko le-Ubuntu lesoftware okanye kwi-terminal abanokuyenza ngokwenza lo myalelo ulandelayo:
sudo apt-get install steghide
Ifayile yokubhaliweyo nge-steghide
Ukubethela ifayile eyimfihlo, kufuneka babe nefayile abafuna ukuyifaka kunye nomfanekiso okanye ifayile yeaudiyo abafuna ukuyifihla kuyo.
I-Steghide ixhasa ukubethela kwi-AU, BMP, JPEG, kunye neentlobo zeefayile ze-WAV.
Ngoku ukuthatha umzekelo sifuna ukufihla ifayile ngaphakathi komfanekiso. Is syntax ekufuneka siyisebenzisile yile ilandelayo:
sudo steghide embed -ef examplefile.txt -cf sample.jpg
Kule meko sibonisa ukuba ifayile kufuneka ibhalwe ngokufihlakeleyo ukusuka kwifolda yangoku ukuya kwifolda yangoku.
Kwimeko apho ifayile yokuqala eyimfihlo ikwenye indawo kwinkqubo yakho, kufuneka banikeze umendo opheleleyo.
Ngokufanayo, ukuba ifayile yakho yomfanekiso ibekwe kwenye indawo, kuya kufuneka uchaze umendo opheleleyo ngalo myalelo.
Ngokusisiseko lo myalelo ubhalwe ngolu hlobo lulandelayo:
sudo steghide embed -ef /ruta/de/archivo/a/ocultar -cf /ruta/de/imagen/o/audio/que/contendrá/el/archivo
Ngokukhawuleza emva koku, isicelo siya kucela ipaswedi efunekayo ukuze kuzinziswe ifayile eyimfihlo.
Eli gama lokugqithisa liza kusetyenziselwa ukukhupha okanye ukuguqulela kwifayile ifayile.
Kulo mzekelo, singene kwifayile yokubhaliweyo kwifayile yeJPEG. Emva koguqulelo oluntsonkothileyo, unokucima ifayile yakho eyimfihlo kwaye ugcine ifayile yemifanekiso eza kuthi kamva isetyenziselwe ukuguqulela.
Ukukhutshwa kwefayile
Ngoku ukukhupha ulwazi olufihliweyo kwifayile, siza kusebenzisa lo myalelo ulandelayo
sudo steghide -sf image.jpg
Apho sibonisa khona indlela yomfanekiso okanye ifayile yeaudiyo enolwazi lwethu olufihliweyo, xa sisenza oku siya kucelwa ukuba sinikezele ngegama eligqithisiweyoUkwenza njalo kuya kukhupha ulwazi esilufihla ngaphakathi kweefayile.
Uyikhupha njani i-Steghide kwi-Ubuntu kunye neziphumo zayo?
Okokugqibela, kwabo bangonelisekanga sisixhobo okanye bafuna nje ukusisusa kwinkqubo yabo, singathatha inyathelo elilandelayo ukuze iSteghide isuswe ngokupheleleyo.
Kuya kufuneka sivule i-terminal nge-Ctrl + Alt + T kwaye kuyo siza kwenza lo myalelo ulandelayo:
sudo apt-get remove steghide
Kwaye ukulungele.
Njengengcaciso yokugqibela, sinokusebenzisa iSteghide kunye nezinye izixhobo ezinje nge Cryptomator Kwaye nokuba I-anyanisi ukuze sikwazi ukwabelana ngolwazi phakathi kweefayile zethu nabanye abantu ngendlela ekhuselekileyo.
