In CS2011 & BOE4.0, when you schedule a report created using Crystal Reports for Enterprise, you have the additional option in Format to create a 'Secured Instance'. This appears regardless of the format you select.
First I though it would create a rptr, but as it's available for all formats, that's not the case.
Then I thought this might encrypt the instance on the FRS, but it doesn't.
Then I checked to see if it did anything clever with the file to prevent downloading, but nothing appears any different.
So, apart from having a 'Yes' in the secured instance column, anybody got any idea what this is for?
