UN/EDIFACT Syntax Level A Encoding/Decoding

See more Encryption Examples

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

import { Crypt2, StringBuilder } from '@chilkat/react-native'

function chilkatExample() {
  // Note: Requires Chilkat v9.5.0.65 or greater.

  const sb = new 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
  const crypt = new Crypt2();
  crypt.cryptAlgorithm = 'aes';
  crypt.cipherMode = 'cbc';
  crypt.keyLength = 256;
  crypt.encodingMode = 'eda';

  const ivHex = '000102030405060708090A0B0C0D0E0F';
  crypt.setEncodedIV(ivHex, 'hex');
  const keyHex = '000102030405060708090A0B0C0D0E0F101112131415161718191A1B1C1D1E1F';
  crypt.setEncodedKey(keyHex, 'hex');

  const 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:
  const decStr = crypt.decryptStringENC(encStr);
  console.log(decStr);
