(Node.js) UN/EDIFACT Syntax Level A Encoding/Decoding

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

Install Chilkat for Node.js and Electron using npm at

Chilkat npm packages for Node.js

Chilkat npm packages for Electron

on Windows, Linux, MacOSX, and ARM

var os = require('os');

    //  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.

    //  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";

    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);
