// Note: Requires Chilkat v9.5.0.65 or greater.

Chilkat.StringBuilder sb = new Chilkat.StringBuilder();
sb.Append("The 5 men of 223rd St");
Debug.WriteLine(sb.GetAsString());

// Encode the utf-8 byte representation of the string in the 
// UN/EDIFACT syntax level A character set.
sb.Encode("eda","utf-8");
Debug.WriteLine(sb.GetAsString());

// EDA Output should be: BTME027FCF6CFARFI94JT6.)F(14KJ2U

// Decode back to the original string.
sb.Decode("eda","utf-8");
Debug.WriteLine(sb.GetAsString());
Debug.WriteLine("----");

// The following requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// The "eda" encoding can be used anywhere within Chilkat.
// For example, with the Crypt2 API
Chilkat.Crypt2 crypt = new Chilkat.Crypt2();
crypt.CryptAlgorithm = "aes";
crypt.CipherMode = "cbc";
crypt.KeyLength = 256;
crypt.EncodingMode = "eda";

string ivHex = "000102030405060708090A0B0C0D0E0F";
crypt.SetEncodedIV(ivHex,"hex");
string keyHex = "000102030405060708090A0B0C0D0E0F101112131415161718191A1B1C1D1E1F";
crypt.SetEncodedKey(keyHex,"hex");

string encStr = crypt.EncryptStringENC("The quick brown fox jumps over the lazy dog.");
// The output is UN/EDIFACT syntax level A 
Debug.WriteLine(encStr);

// Now decrypt:
string decStr = crypt.DecryptStringENC(encStr);
Debug.WriteLine(decStr);
