I would like to encrypt the local copies of my Dropbox files, but not the online versions.
I have log on password protection (not BIOS) on my Windows 7 Ultimate laptop but that's easily circumvented by removing the hard disk and mounting it in another computer. If I lose my laptop, I want to make sure that any client information in my Dropbox doesn't fall into the wrong hands.
I'm not worried about the security of files in the cloud. I trust Dropbox to do a better job at securing my data than me. I also want to be able to access my files from my phone or from the web so encrypting files before uploading is not an option.
My question is: if I simply choose to encrypt the folder using Windows BitLocker encryption (in Folder properties > Advanced), does this fit my requirements? It seems to work but I haven't tried hacking it so I'd appreciate an informed opinion.
