CLI tool to hide and extract text in images using LSB technique. Created for PJC (Programming in C/C++) course at PJAIT university.
9+
10+
## Features
11+
12+
- Hide text in image in .bmp and .ppm format
13+
- Extract text from image in .bmp and .ppm format
14+
- Check if the text can be hidden in the image
15+
- File information (size, format, last modified date, resolution)
16+
17+
## Requirements
18+
19+
* CMake 3.29 or higher
20+
* GCC or clang compiler with C++20 support
21+
* Make
22+
23+
## Building
24+
25+
```bash
26+
$ cmake . .
27+
$ cmake --build .
28+
```
29+
30+
## Usage
31+
32+
```bash
33+
$ ./steganography_cli
34+
Użycie: ./steganography-cli [opcje]
35+
-h Wyświetla dostępne opcje programu
36+
-i / --include "<ścieżka_do_pliku>" Wyświetla informacje o pliku
37+
-c / --check "<ścieżka_do_pliku>" "<wiadomość>" Sprawdza, czy jest możliwe ukrycie wiadomości w pliku
38+
-e / --encrypt "<ścieżka_do_pliku>" "<wiadomość>" Ukrywa wiadomość w pliku graficznym (Wspierane formaty to .bmp i .ppm)
39+
