Hi,
I update a project by changing the ImageEnDBView to TIEDBBitmap, I store the images on disk, everything works fine.
When I use image encryption it works, but I can't decrypt them to display in Imageenview,
for example:

Load picture:
fDBBitmap.LoadImage();

Decrypt image:
Imageenview.Proc.Decrypt('Captiva',ieeaTEA2);

The image always remains encrypted.
I use PNG images.

Thank's for help.
Chouk

Hi Chouk

This works fine in my testing:

  fDBBitmap.LoadImage();
  Imageenview1.Proc.Decrypt('Captiva',ieeaTEA2);


Are you sure the password and/or encryption method is correct?

Hi,
I found the problem, I decrypted the image twice.
Is there a way to tell if an image is encrypted?

Hi

No, I'm afraid there is not. You could use meta-data to store its current status, e.g. TextKeys for PNG images:
