如何以十六进制编码SHA-256散列

如何以十六进制在C＃中正确编码SHA-256散列？如何以十六进制编码SHA-256散列

private static string ToHex(byte[] bytes, bool upperCase) 
{ 
    StringBuilder result = new StringBuilder(bytes.Length * 2); 

    for (int i = 0; i < bytes.Length; i++) 
     result.Append(bytes[i].ToString(upperCase ? "X2" : "x2")); 

    return result.ToString(); 
} 

private string hashRequestBody(string reqBody) 
{ 
    string hashString; 
    using (var sha256 = SHA256Managed.Create()) 
    { 
     var hash = sha256.ComputeHash(Encoding.Default.GetBytes(reqBody)); 
     hashString = ToHex(hash, false); 
    } 

    MessageBox.Show(hashString); 
    return hashString; 
}

我这样做，但结果是与银行的沙箱和我一起工作的不同。

测试数据：

{"CorporateID":"BCAAPI2016","SourceAccountNumber":"0201245680","TransactionID":"00000001","TransactionDate":"2017-09-13","ReferenceID":"refID","CurrencyCode":"IDR","Amount":"10000","BeneficiaryAccountNumber":"0201245681","Remark1":"Transfer Test","Remark2":"Online Transfer"}

银行的沙盒结果：e9d06986c1ed6b063bf59aa873030013725c518631deef2b2147e614017c2141

ToHex（）看起来不错，问题是另一回事。你能显示测试数据吗？ –

@AlexK。编辑:) –

你的结果是正确的输入，你确定你应该只是散列，而不是使用像HMAC的东西？ –

我见过几个解决这个问题，但你的代码是最优雅的。我稍微重新考虑了它并测试了它的答案。我也得到了哈希：

也许这散列银行的不同，因为你改变了JSON字符串删除私人数据？

    } 

    private static string ToHex(byte[] bytes, bool upperCase) 
    { 
     StringBuilder result = new StringBuilder(bytes.Length * 2); 
     for (int i = 0; i < bytes.Length; i++)

     return hashString; 
    }
