C# 中的哈希字符串

使用C#中的哈希字符串

csharp
using System;
using System.Security.Cryptography;
using System.Text;
public class HashStringExample
{
    public static string GetHashString(string input)
    {
        using (SHA256 sha256Hash = SHA256.Create())
        {
            byte[] bytes = sha256Hash.ComputeHash(Encoding.UTF8.GetBytes(input));
            StringBuilder builder = new StringBuilder();
            for (int i = 0; i < bytes.Length; i++)
            {
                builder.Append(bytes[i].ToString("x2"));
            }
            return builder.ToString();
        }
    }
    public static void Main()
    {
        string input = "Hello, world!";
        string hashString = GetHashString(input);
        Console.WriteLine($"Input: {input}");
        Console.WriteLine($"Hash string: {hashString}");
    }
}
