Decimal Integer List Encoding

See more Encryption Examples

The "decList" encoding was added in Chilkat v9.5.0.66 to encode and decode binary bytes from comma-separated decimal integers. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // Note: This example requires Chilkat v9.5.0.66 or greater.

  final byteVals = '84,104,101,32,116,114,117,101,32,115,105,103,110,32,111,102,32,105,110,116,101,108,108,105,103,101,110,99,101,32,105,115,32,110,111,116,32,107,110,111,119,108,101,100,103,101,32,98,117,116,32,105,109,97,103,105,110,97,116,105,111,110,46';

  // Demonstrate encoding/decoding comma-separated decimal integrs to/from binary.
  final binData = CkBinData();
  binData.appendEncoded(byteVals, 'decList');

  // Examine the data in hex
  print('HEX: ${binData.getEncoded('hex')}');

  // Decode to a StringBuilder
  final sb = CkStringBuilder();
  sb.appendBd(binData, 'us-ascii', 0, 0);

  // The bytes were actually the us-ascii char values for the string
  // "The true sign of intelligence is not knowledge but imagination."
  print(sb.getAsString());

  // Now get the bytes in decimal list format again:
  print(binData.getEncoded('decList'));

  // The output of this example is:
  // HEX: 5468652074727565207369676E206F6620696E74656C6C6967656E6365206973206E6F74206B6E6F776C656467652062757420696D6167696E6174696F6E2E
  // The true sign of intelligence is not knowledge but imagination.
  // 84,104,101,32,116,114,117,101,32,115,105,103,110,32,111,102,32,105,110,116,101,108,108,105,103,101,110,99,101,32,105,115,32,110,111,116,32,107,110,111,119,108,101,100,103,101,32,98,117,116,32,105,109,97,103,105,110,97,116,105,111,110,46
