Features

Comprehensive steganography and encryption features across all platforms with military-grade security.

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.)

🖼️ Deniable image format

The secret is written into the least-significant bits of the pixels — and nothing else is. No header, no marker, no signature.

Without the credentials nothing proves a secret exists
Wrong password, plain photo and damaged file fail identically
PNG output (lossless); reads any common input format
Capacity shown before you hide

🛡️ 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

Technical Specifications

Supported Image Formats

  • Input: PNG, JPEG, BMP, HEIC, and other mainstream formats
  • Output: PNG format (lossless compression, optimal for steganography)
  • Processing: Automatic format conversion for optimal steganography results

Encryption Standards

  • Algorithm: AES-256-GCM (authenticated encryption)
  • Key Derivation: PBKDF2-SHA256
  • Salt: 16-byte cryptographically secure random
  • Iterations: 600,000
  • Integrity: GCM authentication tag over the payload, with the container header bound as additional authenticated data

Secret Sharing

  • Algorithm: Shamir’s Secret Sharing over GF(2^8)
  • Threshold: Configurable k-of-n schemes
  • Polynomial: Secure random coefficient generation
  • Reconstruction: Lagrange interpolation

System Requirements

  • iOS: iOS 14.0+ (iPhone 6s and newer, all iPad models) - Available Now
  • macOS: macOS 12.0+ (Monterey and newer) - Available Now
  • Windows / Linux: not offered. StegoSafe is built on the Secure Enclave, Face ID and Touch ID; a version without them would be a different, weaker product.
