Nharembozha, kunyanya mafoni, chimwe chinhu chakavanzika kupfuura makomputa ayo atinowanzo govana nemhuri. Kuvanzika kwakakosha uye panogara paine mukana wekuti isu tinoda kuchengetedza chimwe chinhu chatisingade kuti chero mumwe munhu aone. Pane zvakawanda zvingasarudzwa kuti zviitwe izvi, sekugadzira yakamanikidzwa faira ine password, asi nenzira iyi tiri kureva kuti tine chekuvanza, chiri chokwadi. Kana isu tichida kuviga chimwe chinhu uye hapana anoziva kuti tiri kuchivanza, tinogona nguva dzose viga mafaera mukati memufananidzo.
Izvi zvinogoneka nekuda kwa rairo rekupedzisira rekupedzisira. Izvo uye kutora matanho akakodzera nenzira kwayo. Zvatichaita ndezvekugadzira yakadzvanywa faira ine thumbnail mune iyo maneja faira iri mufananidzo, iyo yatinogona kunyange kuvhura senge chero imwe. Chinhu chega chinogona kuita kuti "vapambi" vafungire ndechekuti tinoisa magigabytes mazhinji mumufananidzo, asi izvo zvatova kune mumwe nemumwe wedu. Pano isu ticha tsanangura maitiro.
Viga mafaera mumufananidzo unoshanda zvizere
Tisati tajekesa nhanho dzekutevera, isu tichataura zvatichaita: tichaenda kutora dhairekitori, mune yangu Chakavanzika Folda, inova iyo ichave iine mafaera ese, tiri kuzomanikidza said folda uye gadzira iyo faira FolderSecreta.zip, isai iyo kumufananidzo daidza Image.png inozove "yekuzvivanza" kana "yekuvhara" uye gadzira iyo faira inongoratidzira mufananidzo mumwe chete asi ichave nemafaira ese mukati, ayo kwandiri anga ari Capture.png. Matanho ekutevera angave anotevera:
- Isu tinoisa iwo mufananidzo uye dhairekitori iyo yatinoda kuviga (FolderSecreta) mukati meiyo yakafanana folda, chero iri. Semuenzaniso, muMagwaro.
- Kana tisina kuzviita kare, tinoisa mafaera ese atinoda kuvanza muFoldSecreta. Ini ndabvisa iyo nzvimbo muzita refaira kuitira kuti zvinhu zvive nyore mune inoteedzera.
- Isu tinomanikidza dhairekitori. Tinogona kuita izvi nekudzvanya kurudyi uye nekushandisa yedu default compressor.
- Isu tinovhura iyo terminal.
- Isu tinoenda kune dhairekitori uko FolderSecreta.zip uye Imagen.png vari pamwechete, mune yangu murairo unenge cd / imba / pablinux / Desktop.
- Nhanho inotevera ndeye "concatenate" iyo ChakavanzikaFolder.zip uye Image.png mafaera muCapture.png faira rekubuda. Iwo wekuraira wemuenzaniso wangu ungave unotevera:
cat Imagen.png CarpetaSecreta.zip > Captura.png
- Chekupedzisira, tinogona kudzima mafaera ese, kunze kwe "Capture.png" ndipo panowanikwa data rese rakavanzika, asi kwete usati watarisa kuti tinogona kurisvinura sezvatichazotsanangura mushure.
Esteganography, viga faira mukati mevamwe
Iye zvino unogona kuita bvunzo: kana isu tikazarura mufananidzo, chirongwa chinoivhura chichatiudza kuti chine huremu hwakajairika, senge kubatwa kwe2mb senge yandakashandisa, asi nekudzvanya kurudyi pamufananidzo uye kupinda mukati mayo properties, tichaona kuti saizi yakati kurei.
