How to Encrypt scanning images inside folder?

Abhilash J A

Hello Everyone,

I have Image Scanner Software Application made in C#.Net. But, I want to Encrypt the images inside File folder . Scanned Images are stored in this location:-

@"E:\File\Images", "*.jpg"

Anyone do not can open the images when he/she directly trying to access from this File folder. It should happen only through using Scanner Software Application.

One of the most simplest and quickest way is to convert your image files to base64 strings and reconvert it when it required.
A normal user will see a complicated string written in a file.

You can use Microsoft classes like "System.Security.Cryptography" to encrypt files.
The following thread has two projects that show how you can encrypt and decrypt Images using LEADTOOLS Imaging toolkit and Microsoft classes.

Note that you might need to modify the project source code to loop through all images in a folder.
