signMessage

public static Sign.SignatureData signMessage(byte[] message,
                                             ECKeyPair keyPair)

signMessage

public static Sign.SignatureData signMessage(byte[] message,
                                             ECKeyPair keyPair,
                                             boolean isHash)

signedMessageToKey

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.
