Supports multiple keys (one per line). Can include or omit "0x" prefix.

ℹ️ How Private Key to Address Conversion Works:

Step 1: Validate the private key (must be 64 hexadecimal characters).

Step 2: Derive the public key using Elliptic Curve multiplication (secp256k1 curve).

Step 3: Apply Keccak-256 hash to the public key (excluding first byte).

Step 4: Take the last 20 bytes of the hash and prepend "0x" to form the Ethereum address.

Note: This process follows the EIP-55 standard for checksum addresses.
