1. Using

using AJ.Code;

// Get all countries that registered
var list = Country.AllCountries;

// Get the country information list for MCC value 234
var countries = Country.GetCountryInfoForMCC(234);

// Get the country information for alpha2 code value "KR"
var country = Country.GetCountryInfoForAlpha2Code("KR");

// Get the country information for alpha3 code value "KOR"
var country = Country.GetCountryInfoForAlpha3Code("KOR");

// Get the country information list for the continent code value NA(North America)
var countries = Country.GetCountryInfoForContinentCode(ContinentCode.NA);

// Get the country information list that has MCC & MNC
var countries = Country.GetCountryInfoForMobileInfo(310, 32); // Guam

// Get Home Country
foreach(var country in countries)
  var homeCountry = country.HomeCountry;  // if country is Guam then homeCountry is USA

CRC

Please see https://www.lammertbies.nl/comm/info/crc-calculation?crc=8005&method=hex Please see https://crccalc.com/

using Algorithm.Check;

var data = Encoding.ASCII.GetBytes("123456789");

// Example for CRC 8
var crc = data.CRC8();
var dataWithCRC = data.WithCRC8();

// Example for CRC 8 MAXIM
var crc = data.CRC8(CRC8Type.Maxim);
var dataWithCRC = data.WithCRC8(CRC8Type.Maxim);


// Example for CRC 16
var crc = data.CRC16();
var dataWithCRC = data.WithCRC16();

// Example for CRC 16 CCITT (xModem)
var crc = data.CRC16(CRC16Type.CCITTxModem);
var dataWithCRC = data.WithCRC16(CRC16Type.CCITTxModem);

// Example for CRC 16 DNP
var crc = data.CRC16(CRC16Type.DNP);
var dataWithCRC = data.WithCRC16(CRC16Type.DNP);

// Example for CRC 32
var crc = data.CRC32();
var dataWithCRC = data.WithCRC32();


// Example for Checksum8
var checksum = data.CheckSum8(CheckSum8Type.Xor);
var dataWithChecksum = data.WithCheckSum8(CheckSum8Type.Xor);

var checksum = data.CheckSum8(CheckSum8Type.Modulo256);
var dataWithChecksum = data.WithCheckSum8(CheckSum8Type.Modulo256);

var checksum = data.CheckSum8(CheckSum8Type.TwosComplement);
var dataWithChecksum = data.WithCheckSum8(CheckSum8Type.TwosComplement);

var checksum = data.CheckSum8(CheckSum8Type.NMEA);
var dataWithChecksum = data.WithCheckSum8(CheckSum8Type.NMEA);

Seed

Please see https://seed.kisa.or.kr/kisa/algorithm/EgovSeedInfo.do

The above site includes an English manual.

The IV value is {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}.

1. Encryption example

// You can set this value to whatever you want. (It must be a 16 byte array)
byte[] SeedKey = new byte[16] { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 3, 4, 5 };
var dataToEncrypt = Encoding.UTF8.GetBytes("test");

var dataEncrypted = SEED.Encrypt(dataToEncrypt, SeedKey); // this method is deprecated.
var dataEncrypted = dataToEncrypt.EncryptWithSeed(SeedKey); // new method. please use this.

2. Decryption example

// The SeedKey must same as the SeedKey used when encryption.
byte[] SeedKey = new byte[16] { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 3, 4, 5 };
var dataDecrypted = SEED.Decrypt(dataEncrypted, SeedKey); // this method is deprecated.
var dataDecrypted = dataEncrypted.DecryptWithSeed(SeedKey); // new method. please use this.
