FormsAuthentication.HashPasswordForStoringInConfigFile() continued…

In "response" to my own previous post: two little extension methods that does exactly what "we" need:

public static string GetHashValue(this MD5 hash, string value) 
{ 
    return GetHashValue(hash, Encoding.UTF8.GetBytes(value)); 
}

public static string GetHashValue(this MD5 hash, byte[] value) 
{ 
    byte[] data = hash.ComputeHash(value); 
    string md5 = ""; 
    for (int i = 0; i < data.Length; i++) 
    { 
        md5 += data[i].ToString("x2").ToLowerInvariant(); 
    } 

    return md5; 
}

Usage:

MD5 md5 = MD5.Create(); 
Console.WriteLine(md5.GetHashValue("test"));
