Stegervary

Stegervary lets you hide messages in PNG images using the Hungarian algorithm for efficient and optimal discrete embedding.

This methodology is generalizable to any robust cover media and support for different file encodings (JPEG, MP4, AVI, WAV) may be added.

Usage

cargo run encode <image_file> <text_file>
cargo run decode <image_file> <text_file_with_indices>
