国密链sm2Verify调用返回false

[longJJ2016]

环境：

[chain] id=1 ; use SM crypto or not, should nerver be changed sm_crypto=true sm_crypto_channel=true

[compatibility] ; supported_version should nerver be changed supported_version=2.8.0

webase-front ：1.5.3

合约代码:

`pragma solidity ^0.4.25;

contract Crypto { function sm3(bytes memory data) public view returns(bytes32){} function keccak256Hash(bytes memory data) public view returns(bytes32){} function sm2Verify(bytes32 message, bytes memory publicKey, bytes32 r, bytes32 s) public view returns(bool, address){} function curve25519VRFVerify(string memory input, string memory vrfPublicKey, string memory vrfProof) public view returns(bool,uint256){} }`

`pragma solidity ^0.4.25; import "./Crypto.sol";

contract MyTest1 {

Crypto crypto;

constructor() public {
    crypto = Crypto(0x5006);
}

function getSm2Verify(bytes32 message, bytes memory publicKey, bytes32 r, bytes32 s) public view returns (bool flag , address result) {
    (flag,result) = crypto.sm2Verify(message, publicKey, r, s);
    return (flag,result);
}

}`

publicKey前缀中前两位04是wedpr自带的标志位，在展示时应该对这个publicKey做特殊处理

使用java-sdk的签名接口签名数据后，返回signDataStr。 验签的话，使用java-sdk的verify方法，代码见下。其中国密和ECDSA的输出signDataStr需要处理下： 国密：signDataStr 去掉00，去掉公钥.substring(2)字符串。 ECDSA: signDataStr 的前两位(00或04,,,)放后边。

public boolean verifyByType(String publicKey, byte[] message, byte[] signature,int encryptType) {
    if (encryptType == CryptoType.SM_TYPE) {
        byte[] messageHash = smCryptoSuite.hash(message);
        return smCryptoSuite.verify(publicKey, messageHash, signature);
    } else {
        byte[] messageHash = ecdsaCryptoSuite.hash(message);
        return ecdsaCryptoSuite.verify(publicKey, messageHash, signature);
    }
}
