System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(string, string)已过时的解决办法

FormsAuthentication.HashPasswordForStoringInConfigFile 方法是一个在.NET 4.5中已经废弃不用的API，参见:

https://msdn.microsoft.com/zh-cn/library/system.web.security.formsauthentication.hashpasswordforstoringinconfigfile(v=vs.110).aspx

 

This is a solution for SH1 variant.

     public static string GetSwcSH1(string value)
     {
        SHA1 algorithm = SHA1.Create();
        byte[] data = algorithm.ComputeHash(Encoding.UTF8.GetBytes(value));
        string sh1 = "";
        for (int i = 0; i < data.Length; i++)
        {
            sh1 += data[i].ToString("x2").ToUpperInvariant();
        }
        return sh1;
     }

For MD5 you only change algorithm to:

MD5 algorithm = MD5.Create();
