Blowfish Enhanced Randomized Audio Steganography

This is a project done as a part of the course Cryptography - Theory and Practice

This script takes in text data as input, encrypts it using blowfish algorithm, and encodes it into an audio file. For more details on the algorithm, refer to the PDF in the repo. The bit depth of the encoding algorithm can be modified in the main.py file to experiment how audio gets distorted for any various bit depths.

Steps to set up the requirements to run the code:

• Go to the projects folder in your terminal.
• Run pip install -r 'requirements.txt' to install the modules required for running the python scripts.

To run the encryption and decryption script

• Run python main.py

To run the analysis script

• Run python analysis.py
