Blockchain Steganography

Hide secret messages in blockchain transactions, export & import blockchains

How to Use:

  1. Create Block: Enter secret message and choose encoding method
  2. Mine Block: Click to add block to blockchain
  3. Export Blockchain: Save your blockchain with hidden messages as JSON
  4. Share Blockchain: Send the JSON file to others
  5. Import Blockchain: Load a blockchain file from someone else
  6. Decode Block: Select a block and decode the hidden message

đŸ•ĩī¸ What is Steganography?

Steganography is the art of hiding information within other information. Unlike encryption (which scrambles data), steganography hides the existence of the message itself. On blockchain, secret messages can be hidden in transaction data, allowing covert communication that's visible on-chain but only decipherable to those who know the encoding method.

Key Concepts:

📚 Encoding Methods

🔤 Hexadecimal (Hex)

Convert each character to its 2-digit hex value.

Example: "Hi" → 4869

đŸ“Ļ Base64

Standard encoding used in web and emails.

Example: "Hello" → SGVsbG8=

đŸ’ģ Binary

Convert to 8-bit binary representation.

Example: "A" → 01000001

đŸ”ĸ ASCII Codes

Decimal ASCII values separated by commas.

Example: "Hi" → 72,105

↩ī¸ Reverse Text

Simple reversal of character order.

Example: "Hello" → olleH
