We have a folder on our server where daily files comes in from a remote machine. Everyday we check if the files came in and if so - we download them to our local machine. There are around 20 daily files totaling 30Mb everyday.
Once we download the files we move the files on the server to a subfolder called ARCHIVE (~3Gb). This process is done automatically by our java program.
The files we get are considered 'sensitive' and we wish encrypt the ARCHIVE folder. One way to do that is by encrypting every file that comes in with our java program but before we go this way I was wondering if there's a better way to do it?
Using ubuntu, I was wondering if there's a way to encrypt an entire folder (archive) and allowing us to continue moving files to this folder. In other words, to put all daily plain files in an encrypted folder and when asking to retrieve those files (from the archive) - we'll need to provide a password for decryption.
Thanks for any pointers
