LSB-Vault is a digital "hide-in-plain-sight" tool that tucks secret computer code inside the pixels of an ordinary png image.
The name comes from the technical method it uses: Least Significant Bit (LSB) steganography. Here is the simple breakdown of how it works:
The "Pixel" Trick: Every pixel in an image is made of numbers representing Red, Green, and Blue (RGB).1 For example, a shade of red might be 255
The Tiny Change: The program changes that number by just one digit (e.g., from 255 to 254). This change is so microscopic that the human eye cannot see any difference in the picture.
The Vault: By repeating this across thousands of pixels, the program "buries" your code into those tiny numerical changes.
The Retrieval: To everyone else, it looks like a normal photo. But when you put it back into the LSB-Vault, the program reads those tiny changes, reconstructs the hidden bits, and reveals the secret code inside.
you need to have the program in the same folder/directory as the png you want to encode or else it will not work
