How do Encrypt or Decrypt passwords using Asp.Net with c#?

Enter your Password, click the Encrypt button, and then click Decrypt.

1. Example Of First Enter Password = "rraannaammeett"
2. EncodePasswordToBase64 function converts your string and gives output
   ans= "cnJhYW5uYWFtbWVldHQ="
3. DecodeFrom64 function convert your strring and give output
   ans="rraannaammeett"

//this function Convert to Encord your Password 
public static string EncodePasswordToBase64(string password) 
{
   try 
   {
      byte[] encData_byte = new byte[password.Length]; 
      encData_byte = System.Text.Encoding.UTF8.GetBytes(password); 
      string encodedData = Convert.ToBase64String(encData_byte); 
      return encodedData; 
   } 
   catch (Exception ex) 
   { 
      throw new Exception("Error in base64Encode" + ex.Message); 
   } 
}
//this function Convert to Decord your Password
public string DecodeFrom64(string encodedData) 
{
   System.Text.UTF8Encoding encoder = new System.Text.UTF8Encoding(); 
   System.Text.Decoder utf8Decode = encoder.GetDecoder();
   byte[] todecode_byte = Convert.FromBase64String(encodedData); 
   int charCount = utf8Decode.GetCharCount(todecode_byte, 0, todecode_byte.Length); 
   char[] decoded_char = new char[charCount]; 
   utf8Decode.GetChars(todecode_byte, 0, todecode_byte.Length, decoded_char, 0); 
   string result = new String(decoded_char); 
   return result;
}
protected void Button1_Click(object sender, EventArgs e)
{ 
   Label1.Text=EncodePasswordToBase64(TextBox1.Text); 
}
protected void Button2_Click(object sender, EventArgs e)
{
   Label1.Text = DecodeFrom64(Label1.Text);
}
