## What it is
A C++ command-line tool that encrypts files with password-protected AES-256-CBC and hides them inside images using Least-Significant-Bit pixel encoding. It supports encoding and decoding embeds with PBKDF2-HMAC-SHA-256 key derivation and CRC32 integrity checks.

## Use cases
- hide a file inside an image
- encrypt and embed a zip into a png
- extract hidden files from steganographic images
- password-protect files hidden in pictures
- send secret files disguised as photos
- lsb steganography from the command line

## When to choose
- you need to covertly embed files into images with strong encryption
- you want a simple cross-platform CLI for LSB steganography
- you prefer a lightweight native C++ tool without heavy dependencies

## When to avoid
- you need steganalysis resistance against advanced detection
- you want to hide data in audio or video files
- you need a GUI or batch processing of many images
