megatruh/steganografi-dengan-enkripsi-elgamal-berbasis-diffie-hellman

This Streamlit application encrypts secret messages, embeds them in images, and supports extraction, decryption, image analysis, and JPEG fragility testing. The main workflow runs from user input through ElGamal encryption and Reed-Solomon-protected, randomized LSB embedding to a downloadable stego image; extraction reverses those stages. The README documents the product branches, and the SOURCE INDEX confirms app.py references the three core modules. Source excerpts are partial, so some links rely on documented workflows rather than inspected call sites.
