Default Behavior

By default the byte array passed in is unchanged and no real decryption occurs. The user should code their own algorithm to decrypt the data.

The byte array passed in can be modified in place and then returned, or if needed a local byte array can be allocated (larger or smaller if needed), populated and returned.

To indicate an error condition, throw a CSUException. That is, throw new CSUException("CFBDynamicMessageDecryptionExit:GetInstance","error message")).
