A command line tool for hiding a file (payload) onto a carrier (image).
Running hips --hide testdata/secret.txt attaches the bytes of the secret.txt onto the embedded carrier image file:
| Before | After |
|---|---|
| Carrier without secret.txt | Carrier with secret.txt |
 |
 |
Can you see the difference? I bet you can't. Only if you look at the filesize.
If you want to get the original data (payload) back, you can run hips --uncover testdata/secret.txt.jpg
If you have Go, you can easily build the project by running go build ..
