A secure steganography app that embeds encrypted messages within digital images, ensuring undetectable data transmission. It features multi-layer protection, supports flexible input options, and provides a user-friendly interface for seamless encoding and decoding.

✅ Multi-Layer Security – Combines encryption & steganography for enhanced protection.
✅ Flexible Input Options – Users can type messages or upload text files.
✅ Algorithm Selection – Choose from AES-128, AES-256, SHA-256, MD5, or basic encoding.
✅ User-Friendly Interface – Intuitive GUI for seamless encoding & decoding.
✅ Error Detection – Prevents incorrect decryption with validations on passwords & algorithms.
✅ Modular Codebase – Separate encryption & decryption modules for maintainability.

pip install -r requirements.txt

python Main.py

• Python (Programming Language)
• Tkinter (GUI Framework)
• Pillow (Image Processing)
• Cryptography (Encryption Algorithms)

1️⃣ Run main.py & choose an image to hide the message.
2️⃣ Choose message input (Type manually or Upload file).
3️⃣ Pick an encryption algorithm & enter a password.
4️⃣ Click "Encode" to embed data.
5️⃣ Save the stego image (with hidden data).

1️⃣ Select the stego image.
2️⃣ Enter the decryption password.
3️⃣ Choose the correct algorithm.
4️⃣ Click "Decode" to retrieve the message.

🔹 Steganography + Encryption → Ensures data remains hidden & protected.
🔹 Wrong Password/Algorithm Detection → Prevents incorrect decryption.
🔹 Read-Only Decoded Message → Protects extracted data from modifications.

🔸 Support for Audio/Video Steganography
🔸 Integration with Cloud Storage
🔸 AI-Powered Steganalysis Detection
