include("chilkat.php");
// Use "chilkat_9_5_0.php" for versions of Chilkat < 10.0.0

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

$crypt = new CkCrypt2();

// Set the name of the hash algorithm.
// Other choices include "sha1", "sha256", "sha384", "sha512", "md2", "md5", and "haval". 
$crypt->put_HashAlgorithm('md5');

// EncodingMode specifies the encoding of the hash output.
// It may be "hex", "url", "base64", or "quoted-printable".
$crypt->put_EncodingMode('hex');

// Files of any type may be hashed -- it doesn't matter
// if the file is binary or text...
