// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

$crypt = new CkCrypt2();

// Here's a string in Icelandic using non us-ascii chars:
$s = 'Ég get etið gler án þess að meiða mig.';

$crypt->put_CryptAlgorithm('none');
$crypt->put_EncodingMode('quoted-printable');

// Quoted-printable encode/decode the iso-8859-1
// representation of the string.  Notice how each
// Icelandic char is represented by 1 byte:
$crypt->put_Charset('iso-8859-1');
$qp = $crypt->encryptStringENC($s);
print 'iso-8859-1:' . "\n";
print $qp . "\n";
$decoded = $crypt->decryptStringENC($qp);
print $decoded . "\n";

// Now do the same using utf-8. Notice how each
// Icelandic char is represented by 2 bytes in utf-8:
$crypt->put_Charset('utf-8');
$qp = $crypt->encryptStringENC($s);
print 'utf-8:' . "\n";
print $qp . "\n";
$decoded = $crypt->decryptStringENC($qp);
print $decoded . "\n";
