Demonstrates the new "eda" encoding that can be used throughout Chilkat starting in v9.5.0.65. Node.js

function chilkatExample() {

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

    var sb = new chilkat.StringBuilder();
    sb.Append("The 5 men of 223rd St");
    console.log(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");
    console.log(sb.GetAsString());

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

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

    // 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
    var crypt = new chilkat.Crypt2();
    crypt.CryptAlgorithm = "aes";
    crypt.CipherMode = "cbc";
    crypt.KeyLength = 256;
    crypt.EncodingMode = "eda";

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

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

    // Now decrypt:
    var decStr = crypt.DecryptStringENC(encStr);
    console.log(decStr);
