如何对SHA-256哈希进行十六进制编码 [英] How to Hex Encode a SHA-256 Hash

问题描述

如何在C＃中正确对SHA-256哈希进行十六进制编码？

How to Hex Encode a SHA-256 hash properly in C#?

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;
}

我这样做了，但是结果与我使用的银行的沙盒不同。

I did this, but the result is different with bank's sandbox I worked with.

测试数据：

{ CorporateID： BCAAPI2016， SourceAccountNumber ： 0201245680， TransactionID： 00000001， TransactionDate： 2017-09-13， ReferenceID： refID， CurrencyCode： IDR， Amount： 10000， BeneficiaryAccountNumber： 0201245681， Remark1：转移测试， Remark2：在线转移}

银行的沙箱结果： e9d06986c1ed6b063bf59aa873030013725c518631deef2b2147e614017c2141

推荐答案

我已经看到了解决此问题的几种方法，但是您的代码是最优雅的。我对其进行了一些重构，并对其进行了测试。我还得到了哈希值：

I've seen several solutions to this problem, but your code is the most elegant. I slightly re-factored it and tested it for this answer. I also get the hash:

1c83acc42cf905ca8afba27ef0640c70ad2856a366b57c17cf16f2894327676e

1c83acc42cf905ca8afba27ef0640c70ad2856a366b57c17cf16f2894327676e

也许此哈希值与银行的哈希值不同，因为您更改了JSON字符串以删除私人数据？

Perhaps this hash is different to the bank's because you changed the JSON string to remove private data?

using System;
using System.Security.Cryptography;
using System.Text;

public class Program
{
    public static void Main()
    {
        Console.WriteLine(SHA256HexHashString("{\"CorporateID\":\"BCAAPI2016\",\"SourceAccountNumber\":\"0201245680\",\"TransactionID\":\"00000001\",\"TransactionDate\":\"2017-09-13\",\"ReferenceID\":\"refID\",\"CurrencyCode\":\"IDR\",\"Amount\":\"10000\",\"BeneficiaryAccountNumber\":\"0201245681\",\"Remark1\":\"Transfer Test\",\"Remark2\":\"Online Transfer\"}"));
    }

    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 static string SHA256HexHashString(string StringIn)
    {
        string hashString;
        using (var sha256 = SHA256Managed.Create())
        {
            var hash = sha256.ComputeHash(Encoding.Default.GetBytes(StringIn));
            hashString = ToHex(hash, false);
        }

        return hashString;
    }
}
