Mosquito

Mosquito is a powerful steganography tool with MQTT support, allowing you to hide and transmit secret data within images.

What it can do

• Steganography

  • Hide text messages in images
  • Hide one image inside another image
  • Multiple encoding algorithms (LSB1, LSB3, LSB4, LSB8)
  • Verification of image capacity before encoding
  • Support for multiple image formats (PNG, JPEG, GIF, BMP, TIFF, WebP)

• Security

  • AES-256-GCM encryption for protected content
  • Password-based protection
  • Image difference analysis to assess stealth

• **MQTT **

  • Send steganographic images via MQTT
  • Receive and automatically save incoming steganographic images
  • Secure communication channels
