.NET Core 通过扩展方法实现密码字符串加密(Sha256和Sha512)

1、字符串扩展方法类加密方法实现

    /// Extension methods for hashing strings    /// 
    public static class HashExtensions    {        /// 
        /// Creates a SHA256 hash of the specified input.        /// 
        /// The input.        /// A hash        public static string Sha256(this string input)        {            if (String.IsNullOrEmpty(input)) return string.Empty;            using (var sha = SHA256.Create())            {                var bytes = Encoding.UTF8.GetBytes(input);                var hash = sha.ComputeHash(bytes);                return Convert.ToBase64String(hash);            }        }        /// 
        /// Creates a SHA256 hash of the specified input.        /// 
        /// The input.        /// A hash.        public static byte[] Sha256(this byte[] input)        {            if (input == null)            {                return null;            }            using (var sha = SHA256.Create())            {                return sha.ComputeHash(input);            }        }        /// 
        /// Creates a SHA512 hash of the specified input.        /// 
        /// The input.        /// A hash        public static string Sha512(this string input)        {            if (string.IsNullOrEmpty(input)) return string.Empty;            using (var sha = SHA512.Create())            {                var bytes = Encoding.UTF8.GetBytes(input);                var hash = sha.ComputeHash(bytes);                return Convert.ToBase64String(hash);            }        }    }}

2、Sha256和Sha512扩展方法调用

using SPACore.Data;using SPACore.Utils;using System;using System.Threading.Tasks;using SPACore.Extensions;//需要添加扩展方法命名空间namespace ConsoleApp1{    class Program    {        static void Main(string[] args)        {            string Pwd = "Aa123456";            //直接通过字符串扩展方法调用            Console.WriteLine(Pwd.Sha256());            Console.WriteLine(Pwd.Sha512());            Console.ReadKey();        }    }} 

注意：

1. 使用扩展的加密方法，需要添加扩展方法实现类HashExtensions的命令空间
2. 直接通过字符串点方法(Pwd.Sha256())调用
