Hello, community!

I've created a audio steganography services with a cli client as my capstone project.

Any feedback on the code would be super helpful. Thank you for your time and attention!

It allows users to hide, extract, and clear secret messages within audio samples using least significant bit (LSB) manipulation. Below is an overview of its key features and design: #### Key Features - **WAV16 Format Support:** The library currently supports only 16-bit WAV audio files. It validates that the file meets the 16-bit requirement before processing. - **Message Embedding:** The library can embed secret messages into audio files by altering the LSBs of audio samples. A header (e.g., "STEG") is embedded along with the message to ensure correct extraction. - Methods include ```hide_message``` for processing files and ```hide_message_binary``` for direct sample manipulation. - **Message Extraction:** It provides methods to retrieve the hidden message from an audio file. - The methods ```extract_message``` and ```extract_message_binary``` work by reading the LSBs and reconstructing the hidden data. - **Message Clearing:** In addition to embedding and extraction, the library can clear the hidden message from an audio file using the provided password to locate the modified samples. - **Password-Based Indexing:** Unique random indices are generated based on a password, ensuring that only users with the correct password can extract or clear the hidden message. - **Configurable LSB Depth:** Users can configure the number of LSBs used (with a default of 1 and a valid range of 1 to 16) to balance between audio quality and message capacity. This is implemented using the builder pattern for easy and flexible configuration. ### [Build app](https://github.com/Van4ooo/StegoWave/tree/capstone-project?tab=readme-ov-file#build-setup) ### [Tutorial](https://github.com/Van4ooo/StegoWave/tree/capstone-project?tab=readme-ov-file#build-setup)
