Hash and salt passwords in C#

Question

I was just going through one of DavidHayden\'s articles on Hashing User Passwords.

Really I can\'t get what he is trying to achieve.

Here is his code:

Answer 1

 protected void m_GenerateSHA256_Button1_Click(objectSender, EventArgs e)
{
string salt =createSalt(10);
string hashedPassword=GenerateSHA256Hash(m_UserInput_TextBox.Text,Salt);
m_SaltHash_TextBox.Text=Salt;
 m_SaltSHA256Hash_TextBox.Text=hashedPassword;

}
 public string createSalt(int size)
{
 var rng= new System.Security.Cyptography.RNGCyptoServiceProvider();
 var buff= new byte[size];
rng.GetBytes(buff);
 return Convert.ToBase64String(buff);
}


 public string GenerateSHA256Hash(string input,string salt)
{
 byte[]bytes=System.Text.Encoding.UTF8.GetBytes(input+salt);
 new System.Security.Cyptography.SHA256Managed();
 byte[]hash=sha256hashString.ComputedHash(bytes);
 return bytesArrayToHexString(hash);
  }
