Core Security Features

🔐 AES-256 Encryption

Military-grade encryption standard used by governments and security agencies worldwide.

Advanced Encryption Standard with 256-bit keys
PBKDF2-SHA256 key derivation, 600,000 iterations
GCM authenticated mode — a damaged or altered image is detected, never silently decrypted into the wrong data

🔄 Shamir Secret Sharing

Split secrets across multiple images for ultimate redundancy and security.

Threshold cryptography (k-of-n sharing)
Polynomial interpolation over finite fields
Configurable share requirements (2-of-3, 3-of-5, etc.)

🖼️ LSB Steganography

Hide data invisibly within image pixels using advanced steganographic techniques.

Least Significant Bit manipulation
PNG output format (lossless compression)
Supports multiple input formats
Capacity analysis and optimization

🛡️ Privacy by Design

No cloud storage, no data collection, completely offline operation.

Zero telemetry or analytics
Local-only processing
No network requirements for core functionality
