      public static java.math.BigInteger signedMessageToKey​(byte[] message, Sign.SignatureData signatureData) throws java.security.SignatureException
      Given an arbitrary piece of text and an message signature encoded in bytes, returns the public key that was used to sign it. This can then be compared to the expected public key to determine if the signature was correct.
      参数:
      message - RLP encoded message.
      signatureData - The message signature components
      返回:
      the public key used to sign the message
      抛出:
      java.security.SignatureException - If the public key could not be recovered or if there was a signature formatTx error.
