* 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 CreateObject('Chilkat_9_5_0.Crypt2')
loCrypt = CreateObject('Chilkat.Crypt2')

* Encrypted content (base64-encoded)

* 256-bit AES key (literally the 32 us-ascii bytes of this string)
lcKey = "sQsPQYesBM5qEM5OSxicFatIiLM459Bu"

* Note: If your AES key is a string, and it's not clearly hex or base64, AND if the length of the string is the exact size of the AES key,
* then *literally* use the ascii chars as the AES key.
