This is a demo, it uses Legacy Bitcoin addresses, which start with a 1 for P2PKH (Pay-to-Public-Key-Hash) addresses.

Legacy Addresses (Base58Check):
    Format: Starts with 1.
    Example: 1PMycacnJaSqwwJqjawXBErnLsZ7RkXUAs.
    Encoding: Base58Check encoding.
    Type: P2PKH (Pay-to-Public-Key-Hash).

This code generates a legacy Bitcoin address from a given public key in hexadecimal format. It performs the following steps:

  1. Hex to Bytes: Converts the input hexadecimal string into a byte array.
  2. SHA-256 Hashing: Computes the SHA-256 hash of the public key bytes.
  3. RIPEMD-160 Hashing: Hashes the SHA-256 result using the RIPEMD-160 algorithm.
  4. Version Byte: Prepends a version byte (0x00) to the RIPEMD-160 hash, indicating it’s for the main Bitcoin network.
  5. Checksum Calculation: Computes the SHA-256 hash of the versioned hash, then performs SHA-256 again to derive a checksum.
  6. Checksum Append: Appends the first four bytes of the checksum to the versioned hash.

  7. Base58 Encoding: Converts the final byte array into a Base58 string, resulting in the Bitcoin address.
