(PHP Extension) Workaround for the deprecated Crypt2.DecryptBytesENC method

Shows how to replace the deprecated DecryptBytesENC method. (Chilkat is moving away from the use of CkByteData.)

Note: This example requires Chilkat v11.0.0 or greater.

// (Chilkat is moving away from using CkByteData)

$bd = new CkBinData();

// in-place encrypt, then get as hex.

// load from hex, then decrypt.
$bd2 = new CkBinData();
