Hi,
I donated for the ProBundle some time ago, and I am trying to use the F5Steg in one of my projects. I did email @Informatix a few days ago but got no reply, so hoping someone in the forums can help.
I am wanting to store a string into an image, and then view this string later in my app.
I am aiming to store a string into a image and then have that image in my app, and then receive the string from the image during runtime. At the moment I have a string in my code with a password assigned to it. If someone decompiles my app they will be able to see this password. I am hoping to store this password (string) into a image to make it a little harder for the hacker to view this password (string).
I used the example project (F5Steg) from the ProBundle and put a string (stored 123456789 as the string during my testing) into the image, and then copied that image from my Android device and put it into my main project into the files tab in the B4A IDE.
In my main project, I then used the following code..
This works and it will display the string I stored into the image.
However, in the B4A IDE it shows:
When I view the log unfiltered it shows:
This is when it's running in debug mode (Rapid debugging).
If I run it in release or legacy debug mode it doesn't show the error:
Unexpected event (missing RaiseSynchronousEvents): test_stringextracted
Check the unfiltered logs for the full stack trace.
Looking on the forums, I think this library is missing something..

Should the above code be OK to return the string from the image, or am I missing something in my code?
I am wanting to store the string in the image and copy it from the DirAssets directory to the customers device. Otherwise if I stored the string during runtime into the image from the customers device, then if someone decomplied my app they would be able to see the string in my code I am storing. This way it will be a little harder for the hacker/customer to view the string.
