// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Crypt2')
$crypt = new COM("Chilkat.Crypt2");

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

$crypt->CryptAlgorithm = 'none';
$crypt->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->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->Charset = 'utf-8';
$qp = $crypt->encryptStringENC($s);
print 'utf-8:' . "\n";
print $qp . "\n";
$decoded = $crypt->decryptStringENC($qp);
print $decoded . "\n";
