修饰符和类型	方法	说明
int	Sha256Hash.compareTo(Sha256Hash other)
byte	ECKey.findRecoveryId(Sha256Hash hash, ECKey.ECDSASignature sig)	Returns the recovery ID, a byte with value between 0 and 3, inclusive, that specifies which of 4 possible curve points was used to sign a message.
static ECKey	ECKey.recoverFromSignature(int recId, ECKey.ECDSASignature sig, Sha256Hash message, boolean compressed)	Given the components of a signature and a selector value, recover and return the public key that generated the signature according to the algorithm in SEC1v2 section 4.1.6.
byte[]	ECKey.sign(Sha256Hash hash)	用私钥对数据进行签名
boolean	ECKey.verify(Sha256Hash sigHash, ECKey.ECDSASignature signature)	Verifies the given R/S pair (signature) against a hash using the public key.
void	ECKey.verifyOrThrow(Sha256Hash sigHash, ECKey.ECDSASignature signature)	Verifies the given R/S pair (signature) against a hash using the public key, and throws an exception if the signature doesn't match
