A PICTURE IS WORTH A THOUSAND WORDS

Title says it all I'm going to be showing how to embed text into a picture.

First of make sure your repos are all up to date you can do this with the following commands in the terminal.
Code:
apt-get update
AND
Code:
aptitude update
Now are repos are up to date we can install the required program with this command
Code:
apt-get install steghide
Now get the picture you want and text file and place them in the same folder like so.



{{{NOTE}}} Make sure your in the directory where you have the files that you want to embed.
Ok now we can run the command
Code:
steghide embed -cf picture.jpg -ef text
Then it will ask you for a passphrase make sure you remember it for when you extract it.
It should look like this.



Now to Extract it make sure you either delete the text file or just move it out of the folder before you do. I'm going to delete it.

Extract
Code:
steghide extract -sf picture.jpg
Should look like this
