🛡️ Welcome to the StegX v2.0 Wiki

StegX is an enterprise-grade, cryptographically authenticated, and statistically invisible data concealment framework for lossless image formats. It is the first open-source steganography tool to combine all of the following in a single pipeline:

  • Argon2id memory-hard key derivation (winner of the Password Hashing Competition)
  • Dual-Cipher AEAD encryption (AES-256-GCM + ChaCha20-Poly1305)
  • Non-Linear LSB embedding driven by a cryptographic PRNG
  • Adaptive Laplacian/HILL Cost Maps for steganalysis-resistant pixel selection
  • F5-inspired Matrix Embedding (Hamming codes) for minimal modification density
  • Shamir Secret Sharing over GF(2⁸) for threshold-based multi-image distribution
  • Hardware 2FA via YubiKey HMAC-SHA1 Challenge-Response
  • FIPS 140 compliance mode restricting the pipeline to PBKDF2 + AES-GCM + zlib
  • Panic Mode with cryptographic LSB destruction and optional decoy payloads
  • Secure Memory with OS-level page locking (mlock/VirtualLock) and deterministic zeroization

This wiki serves as both a user guide and an academic reference. Every cryptographic claim is substantiated with mathematical definitions, and every architectural decision is traceable to the source code.
