// This example assumes 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 are some bytes as a hex string
$hex = '4142434445462140232425';

// The ReEncode method converts a string from one encoding to another.
// Valid encodings are "url", "base64", "qp", "hex", "modbase64", "base64url", "base32", "base58",
// and any of the encodings listed here:  http://cknotes.com/chilkat-binary-encoding-list

// Convert from hex to base64
$b64 = $crypt->reEncode($hex,'hex','base64');
print 'base64: ' . $b64 . "\n";

// Convert from base64 to base32
$b32 = $crypt->reEncode($b64,'base64','base32');
print 'base32: ' . $b32 . "\n";

// Convert from base32 back to hex
$hex = $crypt->reEncode($b32,'base32','hex');
print 'hex: ' . $hex . "\n";
