How do I encrypt a data file so that it cannot be read without the proper authority?
I have an application where the customer should not have access to the data I need to record for troubleshooting purposes. (there are industrial secrets I wish to protect) My plan is to record a datalog (currently I am producing a tab-delimited spreadsheet format) whenever the device is running and hide the files where they will probably not be found. But some sort of encryption or at least password protection would be better.
I've never tried to do this before, but thought it would be fairly easy. Maybe I'm just not looking in the right places.
Thanks
