Kwesinye isikhathi, sidinga ukubethela idatha eyimfihlo kakhulu kumasistimu ethu ukuze kungabikho omunye umuntu osebenzisa uhlelo lwethu ongathi sigodle imininingwane.
Enye indlela yokwenza lokhu ngokufihla amafayela ayimfihlo nemilayezo ngaphakathi kwamanye amafayela akhona, njengezithombe nomsindo.
Nalokhu futhi ilusizo kakhulu lapho ufuna ukuthumela umyalezo oyimfihlo noma ukuthumela ifayili ngenethiwekhi komunye umuntu ngaphandle kokubeka engozini ukuphepha kwakho.
Bangamane bashumeke idatha eyimfihlo, kanye nephasiwedi noma ukhiye wokungena ukuze kube umuntu othembekile kuphela ongavula lelo fayela.
Lolu hlobo lokubethela lapho ufihla ngokuphepha ifayela elilodwa kwelinye libizwa nge-steganography..
I-Steganography incanyelwa kune-cryptography ngoba ngokuhamba kwesikhathi umphikisi uzokwazi ukuthi kukhona obekufihliwe embhalweni noma kufayela. Bangakwazi ngisho nokuphula ikhodi futhi bathole ulwazi ngokusebenza kanzima.
KuSteganography, noma kunjalo, umuntu wesithathu ubengeke aze azi ukuthi isithombe noma ifayili lomsindo elibonakala lingenabungozi liphethe umyalezo oyimfihlo noma ifayela elifakwe kuwo.
Ukufaka iSteghide ku-Ubuntu 18.10 nakwezinye izinto eziphuma kuzo
I-Steghide iyinsiza yomugqa womyalo ekuvumela ukuthi ufihle idatha eyimfihlo ngaphakathi kwezinhlobo ezahlukahlukene zamafayela wesithombe nawomsindo.
Steghide isebenza kusuka kukhonsoli kuWindows nakuGNU / Linux, futhi kuyiphrojekthi yomthombo ovulekile ehlala kuphela cishe ku-3Mb engafakwanga uziphu, futhi ayidingi ukufakwa, ngakho-ke ingasetshenziswa kuma-pendrives.
Noma kuleli cala sizofaka inguqulo yakamuva yaleli thuluzi, Bangakwenza ngokuyifuna ngqo esikhungweni sesoftware Ubuntu noma kusuka ku-terminal abangakwenza ngokwenza umyalo olandelayo:
sudo apt-get install steghide
Ukubethela kwefayela nge-steghide
Ukubethela ifayela eliyimfihlo, badinga ukuba nefayela abafuna ukulibethela nesithombe noma ifayela lokulalelwayo abafuna ukulifihla kulo.
I-Steghide isekela ukubethela ezinhlotsheni zefayela le-AU, BMP, JPEG, ne-WAV.
Manje ukuthatha isibonelo sifuna ukufihla ifayela ngaphakathi kwesithombe. I-syntax okufanele siyisebenzise yile elandelayo:
sudo steghide embed -ef examplefile.txt -cf sample.jpg
Kulokhu sikhombisa ukuthi ifayili kufanele libethelwe kusuka kufolda yamanje kuye kufolda yamanje.
Uma kwenzeka ifayili eliyimfihlo lokuqala likwenye indawo kusistimu yakho, kufanele linikeze indlela yalo ephelele.
Ngokufanayo, uma ifayela lakho lesithombe litholakala kwenye indawo, kufanele ucacise indlela yalo ephelele ngalo myalo.
Ngokuyinhloko umyalo ubhalwe kanjena:
sudo steghide embed -ef /ruta/de/archivo/a/ocultar -cf /ruta/de/imagen/o/audio/que/contendrá/el/archivo
Masinyane ngemuva kwalokhu, uhlelo luzocela iphasiwedi edingekayo ukushumeka ifayela eliyimfihlo.
Le phasiwedi yilokho okuzosetshenziselwa ukukhipha noma ukubhala ngemfihlo ifayili.
Kulesi sibonelo, sishumeke ifayela lombhalo kufayela le-JPEG. Ngemuva kokuthi ukubethela sekuphelile, ungasusa ifayela lakho eliyimfihlo lokuqala bese ugcina ifayili lesithombe elizosetshenziselwa ukususa ukuqaqwa kwesikhashana kamuva.
Ukukhishwa kwefayela
Manje ukukhipha imininingwane efihliwe ngaphakathi kwefayela, sizosebenzisa umyalo olandelayo
sudo steghide -sf image.jpg
Lapho sikhomba khona indlela yesithombe noma ifayili lomsindo eliqukethe imininingwane yethu efihliwe, lapho senza lokhu sizocelwa ukuthi sinikeze iphasiwediUkwenza kanjalo kuzokhipha imininingwane esiyifihla ngaphakathi kwamafayela.
Ungayikhipha kanjani i-Steghide kusuka ku-Ubuntu nakwezinye izinto?
Ekugcineni, kulabo abanganelisekanga ngaleli thuluzi noma abafuna nje ukulisusa ohlelweni lwabo, singathatha isinyathelo esilandelayo ukuze uSteghide aqedwe ngokuphelele.
Kufanele sivule i-terminal nge-Ctrl + Alt + T futhi kuyo sizokwenza umyalo olandelayo:
sudo apt-get remove steghide
Futhi ngomumo.
Njengamazwana wokugcina, singasebenzisa iSteghide namanye amathuluzi afana ne- I-Cryptomator futhi ngisho ne- I-OnionShare ukwazi ukwabelana ngolwazi ngaphakathi kwamafayela ethu nabanye abantu ngendlela ephephile.
