Reinventing the cryptographic wheel
I've seen a lot of articles that contain some home-brewed algorithm for converting a string password into a cryptographic key for use with symmetric encryption (DES, Triple-DES, Rijndael, etc.)
You don't need an algorithm for this; it's already in the box.
byte[] salt = new byte[2] {200, 100}; // can also use null salt
PasswordDeriveBytes p = new PasswordDeriveBytes("MyPassword",salt);
int bytesInKey = 32;
byte[] key = p.GetBytes(bytesInKey);
foreach (byte b in key)
{
Console.Write(b.ToString("X"));
}
Console.WriteLine();
Returns:
