Sample code for encryption and decryption code...

using System.Text;

private string Encryptdata(string password)
    {
        string strmsg = string.Empty;
        byte[] encode = new byte[password.Length];
        encode = Encoding.UTF8.GetBytes(password);
        strmsg = Convert.ToBase64String(encode);
        return strmsg;
    }
   
    private string Decryptdata(string encryptpwd)
    {
        string decryptpwd = string.Empty;
        UTF8Encoding encodepwd = new UTF8Encoding();
        Decoder Decode = encodepwd.GetDecoder();
        byte[] todecode_byte = Convert.FromBase64String(encryptpwd);
        int charCount = Decode.GetCharCount(todecode_byte, 0, todecode_byte.Length);
        char[] decoded_char = new char[charCount];
        Decode.GetChars(todecode_byte, 0, todecode_byte.Length, decoded_char, 0);
        decryptpwd = new String(decoded_char);
        return decryptpwd;
    }



string strpassword = Encryptdata(TextBox1.Text); //Enc

string strpassword = Decryptdata(TextBox1.Text); //Dec
