# Stegasoo
|
||||||
|
|
||||||
|
A secure steganography system for hiding encrypted messages and files in images using hybrid multi-factor authentication.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|
- 🔐 **AES-256-GCM** authenticated encryption
|
||||||
|
- 🧠 **Argon2id** memory-hard key derivation (256MB RAM requirement)
|
||||||
|
- 🎲 **Pseudo-random pixel selection** defeats statistical steganalysis
|
||||||
|
- 📅 **Daily key rotation** with BIP-39 passphrases (3-12 words)
|
||||||
|
- 🔑 **Multi-factor authentication**: Reference photo + phrase + PIN/RSA key
|
||||||
|
- 📁 **File embedding** - Hide any file type (PDF, ZIP, documents, etc.)
|
||||||
|
- 📊 **Large capacity** - Up to 6MB payload in 24MP images
|
||||||
|
- 🔍 **QR code support** - Store RSA keys in QR code images
|
||||||
|
- 🚀 **Three complete interfaces**: CLI, REST API, and Web UI

||||||

Security Model
|
||||||
|
Multi-Factor Authentication
|
||||||
|
Stegasoo combines multiple authentication factors for unprecedented security:
|
||||||
|
|
||||||
|
Factor Type Entropy Description
|
||||||
|
Reference Photo Something you have 80-256 bits A photo both parties secretly share
|
||||||
|
Daily Phrase Something you know 33-132 bits Rotating passphrase (BIP-39 words)
|
||||||
|
Static PIN Something you know 20-30 bits 6-9 digit number (optional)
|
||||||
|
RSA Key Something you have 112-256 bits 2048-4096 bit key (optional)
|
||||||
|
Combined Hybrid 133-400+ bits Computational infeasibility
|
||||||
|
Security Configurations
|
||||||
|
Configuration Total Entropy Use Case
|
||||||
|
Photo + 3-word phrase + 6-digit PIN ~133 bits Casual communication
|
||||||
|
Photo + 6-word phrase + 9-digit PIN ~186 bits Business communication
|
||||||
|
Photo + 3-word phrase + RSA 2048 ~241 bits High-security documents
|
||||||
|
Photo + 6-word phrase + PIN + RSA 4096 ~400+ bits Military-grade secrecy
|
||||||
|
Cryptographic Guarantees
|
||||||
|
AES-256-GCM: Authenticated encryption prevents tampering
|
||||||
|
|
||||||
|
Argon2id: Memory-hard KDF (256MB) defeats GPU/ASIC attacks
|
||||||
|
|
||||||
|
Random salt per message: Prevents rainbow table attacks
|
||||||
|
|
||||||
|
Pseudo-random pixel selection: Defeats statistical steganalysis
|
||||||
|
|
||||||
|
Date-based key rotation: Limits exposure if credentials leak
|
||||||
|
|
||||||
|

|
||||||

Advanced Features
|
||||||
|
|
||||||
|
QR Code Support
|
||||||
|
|
||||||
|
Store RSA keys as QR code images for physical key storage:
|
||||||
|
|
||||||
|
bash
|
||||||
|
# Generate RSA key and create QR code
|
||||||
|
stegasoo generate --rsa --output key.pem -p "password"
|
||||||
|
|
||||||
|
# Encode using QR code key
|
||||||
|
stegasoo encode -r ref.jpg -c carrier.png -p "phrase" --key-qr keyqr.png -m "secret"
|
||||||
|
|
||||||
|
# API: Extract key from QR code
|
||||||
|
curl -X POST http://localhost:8000/extract-key-from-qr -F "qr_image=@keyqr.png"
|
||||||
|
File Embedding
|
||||||
|
Hide any file type (PDF, ZIP, documents, etc.):
|
||||||
|
|
||||||
|
bash
|
||||||
|
# Embed a PDF document
|
||||||
|
stegasoo encode -r ref.jpg -c carrier.png -p "phrase" --pin 123456 -e document.pdf
|
||||||
|
|
||||||
|
# Embed an archive
|
||||||
|
stegasoo encode -r ref.jpg -c carrier.png -p "phrase" --pin 123456 -e archive.zip
|
||||||
|
|
||||||
|
# Decode automatically detects file vs text
|
||||||
|
stegasoo decode -r ref.jpg -s stego.png -p "phrase" --pin 123456 -o extracted.pdf
|
||||||
|
Piping and Automation
|
||||||
|
bash
|
||||||
|
# Pipe messages from stdin
|
||||||
|
echo "Secret" | stegasoo encode -r ref.jpg -c carrier.png -p "phrase" --pin 123456 > stego.png
|
||||||
|
|
||||||
|
# JSON output for scripting
|
||||||
|
creds=$(stegasoo generate --json)
|
||||||
|
pin=$(echo "$creds" | jq -r '.pin')
|
||||||
|
monday_phrase=$(echo "$creds" | jq -r '.phrases.Monday')
|
||||||
|
|
||||||
|
# Batch processing with quiet mode
|
||||||
|
for file in secrets/*.txt; do
|
||||||
|
stegasoo encode -r ref.jpg -c carriers/${file}.png -p "phrase" --pin 123456 -f "$file" -q
