Ezinsukwini ezithile ezedlule sikhuluma lapha kubhulogi ngethuluzi elihle kakhulu le-steganography ubani igama layo I-Steghide eyinsiza yomugqa womyalo lokho kukuvumela ukuthi ufihle idatha eyimfihlo ngaphakathi kwezinhlobo ezahlukahlukene zamafayela wesithombe nawomsindo.
Namuhla sizokhuluma ngelinye ithuluzi le-steganography esebenza kulayini womyalo futhi izosisiza ukuba sibone ngeso lengqondo imininingwane yethu, ithuluzi okufanele sikhulume ngalo namuhla Ibizwa ngokuthi i-Outguess.
I-Outguess nayo insiza yomugqa we-command steganography evumela ukuthi imininingwane efihliwe ifakwe kumabhithi angafuneki emithombo yedatha.
Uhlelo lithembele kubaphathi bemininingwane ethile abazokhipha izingcezwana ezingasafuneki futhi bazibhale ngemuva kokuguqulwa.
Amafomethi wefayela lokho Ukukhishwa okusekelwa njengamanje kufaka phakathi i-JPEG, i-PPM, ne-PNM, noma ungasebenzisa noma yiluphi uhlobo lwedatha, inqobo nje uma kunikezwa umshayeli.
Ngenhlanhla Outguess ingaphakathi kwamakhosombe wokusabalalisa okuningi kwe-Linux, ngakho-ke ukufakwa kwayo kulula.
Ungayifaka kanjani i-Outguess ku-Ubuntu nakwezinye izinto?
Uma unentshisekelo yokukwazi ukufaka leli thuluzi kusistimu yakho Kufanele uvule i-terminal futhi kuyo uzothayipha umyalo olandelayo:
sudo apt-get install outguess
Futhi usuqedile ngakho, ungaqala ukusebenzisa leli thuluzi kusistimu yakho.
Ungawabethela kanjani amafayela ngosizo lwe-Outguess?
Yebo, lapho ukufakwa kohlelo lokusebenza sekuqediwe, njengoba kushiwo ngenhla, leli thuluzi lisebenza kulayini womyalo, ngakho-ke kufanele sivule i-terminal futhi kuyo sizokwenza isivivinyo sethu se-steganography.
Lapha kulokhu kufanele sibe nefayela esifuna ukulifihla futhi sibe nefayela elizosebenza njengesitsha sefayela elifihliwe.
Kulesi sivivinyo esilula, Sizokwakha noma yiliphi ifayela le-txt futhi kulokhu bazofaka umbhalo abawufunayo.
Ngenxa yalokhu sizokuthayipha:
touch oculto.txt
Manje sizokwengeza noma yimuphi umbhalo kuwo:
nano oculto.txt
Usuvele ufake umbhalo owufunayo, ungaqhubeka nokugcina ifayili nge-Ctrl + O bese uphuma ku-nano nge-Ctrl + X
Manje umyalo wokufihla imininingwane ngaphakathi kwefayela olikhethile wenziwa kanjena:
outguess -k "clave secreta" -d /ruta/de/archivo/a/ocultar/oculto.txt /ruta/de/imagen.jpg /ruta/del/archivo/de/salida.jpg
Lapho "ukhiye oyimfihlo" kuzoba ukhiye ozocelwa ukukhipha imininingwane oyifihlayo kanti okunye kumane kuyizindlela lapho amafayela akho owakhethe khona ekuqaleni.
Kunconywa ukuthi ube nabo kufolda efanayo ukuze umyalo ube kanjena:
outguess -k "clave secreta" -d oculto.txt imagen.jpg image-salida.jpg
Njengoba ukwazi ukubona sicabanga ukuthi ifayela lizobethelwa lisuka kufolda yamanje liye kufolda yamanje.
Uma kwenzeka ifayela lokuqala elizobethelwa likwenye indawo kusistimu yakho, kufanele unikeze indlela yalo ephelele.
Ngokufanayo, uma ifayela labo lesithombe likhona kwenye indawo, kufanele bacacise indlela yalo ephelele.
Ngemuva kokuthi ukubethela kwenziwe, bangasusa ifayela lakho le-txt bese bagcina ifayili lesithombe elikhiphayo elizosetshenziselwa ukususa ukuqaqanjelwa.
Ungawakhipha kanjani amafayela afihliwe ngokuzikhandla?
Manje ukubona ukuthi inqubo yethu yangaphambilini isebenze, sizoqhubeka sikhiphe ifayili ebesilifihle ekuqaleni esithombeni abasikhethile.
Indlela okwakhiwe ngayo umyalo wokukhipha imi kanje:
outguess -k "clave secreta" -r /ruta/de/imagen/imagen.jpg “nombre-de-archivo-que-se-oculto.txt”
Lapho "ukhiye oyimfihlo" kungukhiye owabelwe ukuvikela ifayela. Okulandelayo kufana nendlela yesithombe enefayela elifihliwe futhi okulandelayo igama lefayela ebelifihliwe.
Endabeni yesibonelo esisenzayo, singathayipha umyalo olandelayo:
outguess -k "clave secreta" -r imagen-salida.jpg oculto.txt
Ngemuva kokukhishwa, ithuluzi le-Outguess liphinde lihlole izibalo ukuqinisekisa ukuthi ifayela lokuqala linjengoba lalinjalo ngaphambi kokubethela.
