Hide & Seek

This tool hides (encrypts) secret text inside an image using steganography so it's not visible to the eye. The encryption process ensures only authorized users with the correct key or method can extract the hidden message. It can also decrypt and reveal the hidden text back from the image when needed.

Questions about our creative and security tools

How secure is the steganography tool?

+

Our steganography tool uses advanced algorithms to hide text within image pixels invisibly. The hidden text is encrypted before embedding, making it extremely difficult to detect or extract without the proper key.

Can I encrypt large amounts of text?

+

Yes! Our text encryption tool can handle up to 50,000 characters. For steganography, the limit depends on the image size - larger images can hide more text while maintaining invisibility.

What encryption methods do you use?

+

We use industry-standard AES encryption for text protection and LSB (Least Significant Bit) steganography for image hiding. All encryption happens locally in your browser for maximum security.

Can these tools be used for educational purposes?

+

Absolutely! These tools are perfect for learning about cryptography, steganography, and digital security. They're commonly used in computer science courses and cybersecurity training.

What image formats work with steganography?

+

Our steganography tool works best with PNG and BMP formats as they preserve exact pixel values. JPEG can also be used but may have slight quality loss that could affect hidden data.
