Recover public key from raw Ethereum tx data
This is a tool to help recover public keys from Ethereum raw tx data, which supports both EIP-1559 tx/s and EIP-155 tx/s (i.e. before EIP-1559).
Public keys are either
1. 65 bytes long and look like
0x04 || uncompressed public key2. 33 bytes long and look like
0x02 or 0x03 || compressed public key
Ethereum addresses are the last 20 bytes of the hash of the uncompressed public key
