Decryption Code:

System.Text.Decoder utf8Decode = encoder.GetDecoder();
byte[] todecode_byte = Convert.FromBase64String(sData);

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;
}
Event fire Code for Encryption:
protected void Button1_Click(object sender, EventArgs e)
{
string result = base64Encode(TextBox1.Text);
Label1.Text = result;
}
Event fire Code for Decryption:
protected void Button2_Click(object sender, EventArgs e)
{
string result = base64Decode(TextBox2.Text);
Label2.Text = result;
}
