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. Chilkat2 PHP

<?php

use Chilkat2\Crypt2;
use Chilkat2\StringBuilder;

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

$sb = new StringBuilder();
$sb->Append('The 5 men of 223rd St');
echo $sb->GetAsString(), "\n";

// Encode the utf-8 byte representation of the string in the
// UN/EDIFACT syntax level A character set.
$sb->Encode('eda', 'utf-8');
echo $sb->GetAsString(), "\n";

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

// Decode back to the original string.
$sb->Decode('eda', 'utf-8');
echo $sb->GetAsString(), "\n";
echo "----\n";

// 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
$crypt = new Crypt2();
$crypt->CryptAlgorithm = 'aes';
$crypt->CipherMode = 'cbc';
$crypt->KeyLength = 256;
$crypt->EncodingMode = 'eda';

$ivHex = '000102030405060708090A0B0C0D0E0F';
$crypt->SetEncodedIV($ivHex, 'hex');
$keyHex = '000102030405060708090A0B0C0D0E0F101112131415161718191A1B1C1D1E1F';
$crypt->SetEncodedKey($keyHex, 'hex');

$encStr = $crypt->EncryptStringENC('The quick brown fox jumps over the lazy dog.');
// The output is UN/EDIFACT syntax level A
echo $encStr, "\n";

// Now decrypt:
$decStr = $crypt->DecryptStringENC($encStr);
echo $decStr, "\n";
