🔐 Advanced Cryptography: Vigenère Cipher with Steganography
The Vigenère cipher, known as 'le chiffre indéchiffrable' (the indecipherable cipher), was considered unbreakable for over 300 years. This challenge combines classical polyalphabetic encryption with modern steganographic techniques to create a multi-layered security puzzle.
🎯 What You'll Learn
- ✓ Vigenère cipher mechanics and cryptanalysis
- ✓ LSB (Least Significant Bit) steganography
- ✓ Multi-layer security implementations
- ✓ Image-based data hiding techniques
🔍 Challenge Overview
You'll encounter an encrypted message that requires both steganographic analysis and cryptographic decryption. The cipher key is hidden within an image using steganographic techniques, and the encrypted text must be decoded using the Vigenère method.
