// 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");

$content = 'abcdefghijklmnopqrstuvwxyz';

// The desired output is a hexidecimal string:
$crypt->EncodingMode = 'hex';

// Set the hash algorithm:
$crypt->HashAlgorithm = 'ripemd128';

$hashStr = $crypt->hashStringENC($content);

print $hashStr . "\n";

// The output is:
// FD2AA607F71DC8F510714922B371834E

$crypt->HashAlgorithm = 'ripemd160';
$hashStr = $crypt->hashStringENC($content);
print $hashStr . "\n";

// The output is:
// F71C27109C692C1B56BBDCEB5B9D2865B3708DBC

$crypt->HashAlgorithm = 'ripemd256';
$hashStr = $crypt->hashStringENC($content);
print $hashStr . "\n";

// The output is:
// 649D3034751EA216776BF9A18ACC81BC7896118A5197968782DD1FD97D8D5133

$crypt->HashAlgorithm = 'ripemd320';
