Convert String to SecureString

Question

How to convert String to SecureString?

Answer 1

The following 2 extensions should do the trick:

1. For a char array

   public static SecureString ToSecureString(this char[] _self)
   {
       SecureString knox = new SecureString();
       foreach (char c in _self)
       {
           knox.AppendChar(c);
       }
       return knox;
   }
   

2. And for string

   public static SecureString ToSecureString(this string _self)
   {
       SecureString knox = new SecureString();
       char[] chars = _self.ToCharArray();
       foreach (char c in chars)
       {
           knox.AppendChar(c);
       }
       return knox;
   }
   

Thanks to John Dagg for the AppendChar recommendation.
