簽名總是 132 個字元而不是 65 個字元

我難住了。我正在嘗試使用 ECSDA / keccak256 創建簽名。在 Solidity 中，恢復方法需要 65 個字元。我的集成程式碼 (.net C#) 中的簽名。我不知道我的邏輯有什麼問題。有什麼想法嗎？我寫了一個單元測試來幫助我測試一些不同的東西，但它總是 132 個字元。有什麼建議麼？

   [Fact]
   public void AbleToSignAndVerify()
   {
       // Arrange
       var abiEncode = new ABIEncode();
       var privateKey = "0x0000000000000000000000000000000000000000";
       var publicKey = "0x0000000000000000000000000000000000000000";
       var senderAddress = "0x0000000000000000000000000000000000000000";
       var textToHash = "\x19Ethereum Signed Message:\n" + senderAddress.Length + senderAddress;

       //var msgBytes = Encoding.UTF8.GetBytes(textToHash);
       var encodedValue = abiEncode.GetABIEncodedPacked(textToHash);
       byte[] msgHash = new Sha3Keccack().CalculateHash(encodedValue);

       var signer1 = new EthereumMessageSigner();
       var signer2 = new EthereumMessageSigner();

       // Act
       var signature1 = signer1.Sign(msgHash, new EthECKey(privateKey));
       var length = signature1.Length;
       var addressRec2 = signer2.EcRecover(msgHash, signature1);
       var signatureByteArray = Encoding.UTF8.GetBytes(signature1);
       var baLength = signatureByteArray.Length;
       var signatureHex = signatureByteArray.ToHex();
       var shLength = signatureHex.Length;
       var signatureHexCompact = signatureByteArray.ToHexCompact();
       var shcLength = signatureHexCompact.Length;

       // Assert
       Assert.Equal(publicKey, addressRec2);

   }

對於未來的人，評論中的伊斯梅爾是正確的。我也有編碼和散列問題。此解決方案取決於 .net Nethereum 庫。注意事項 - 我的數據類型是發件人地址，因此 ABIValue TYPE 設置為“地址”。這產生了巨大的變化。

   private byte[] GetSignature(string privateKey, string textToHash)
   {
       var abiEncode = new ABIEncode();
       var abiValue = new ABIValue("address", textToHash);
       var encodedValue = abiEncode.GetABIEncodedPacked(abiValue);

       var hashing = new Sha3Keccack();
       byte[] msgHash = hashing.CalculateHash(encodedValue);

       var key = new EthECKey(privateKey);

       var signer = new EthereumMessageSigner();

       var signature = signer.SignAndCalculateV(msgHash, key);

       var signatureByteArray = signature.To64ByteArray();

       return signatureByteArray;
   }
