Your Security & Privacy with StegGuard

  • All steganography operations (encoding, decoding) and text encryption happen client-side in your browser.
  • Your images, messages, and passwords are never sent to any server.
  • LSB (Least Significant Bit) steganography is used to embed data. While subtle, it's not cryptographically unbreakable without message encryption.
  • For sensitive messages, always use a strong password for encryption. We use AES-GCM.
  • Passwords are strengthened using PBKDF2 with a unique random salt (100,000 iterations) for each encryption.
  • "Share Links" are session-based. For persistent sharing, download and share the generated steganographic image file.
  • Steganography is for hiding the existence of a message. Strong encryption protects its content. Combining both enhances privacy.

StegGuard empowers you to securely hide text messages within images using advanced client-side steganography. Encrypt your sensitive information and embed it directly in your browser, ensuring your data never leaves your computer.
