/!A
Syntax: /!A
The /!A parameter works like the /!a parameter and can be used to determine if a file is encrypted or not. If the file is encrypted additional information will be displayed. This additional information contains the name and version of the application which was used to encrypt the file.
This feature is supported since Version 1.1. If an application from the CCrryyppttoo Suite with Version 1.0 was used to encrypt the file the application name cannot be determined. In this case the application name will be displayed as "(unknown)".
