// UN/EDIFACT syntax level A character set.

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

// The "eda" encoding can be used anywhere within Chilkat.
// For example, with the Crypt2 API

$crypt->put_CipherMode('cbc');
$crypt->put_KeyLength(256);
$crypt->put_EncodingMode('eda');
