Files are encrypted individually, and are otherwise just normal files on the file system. That does mean that ownership, size and permissions are visible as well. You mount the directory to another folder to access plain-text contents. Dropbox would only have the encrypted folder of course.</div><div><br></div><div>There are compatible ports for Windows and Mac, as well as a non-free commercial app for iOS. There was one parameter (forget off-hand) which was required, as default creation took the full path into account, and would not be usable anywhere else.</div><div><br>On Aug 12, 2014, at 13:00, Dan Martin <<a href="mailto:ummar143@gmail.com">ummar143@gmail.com</a>> wrote:<br><br></div><blockquote type="cite"><div><div dir="ltr">I am in need of encryption software that would keep files encrypted on the cloud as well as local on all machines.<div><br></div><div>Here is what I'm looking for:</div><div><br></div><div>Downloaded files saved to a particular folder on a Windows 7 or 8 machine would automatically be encrypted (after a prompt for passphrase).

<div><br></div><div>I would prefer that the files are individually encrypted with the same passphrase, rather than added to one large file which is encrypted.

<div><br></div><div>Since I will be the only user in the foreseeable future, a symmetric encryption scheme would be fine.</div><div><br></div><div>From the cloud (preferably) or thumb drive folder, my ruby program running on Mac OS X would edit the files.

<div><br></div><div>This is the ideal. An alternative would be to send the files via https to a web server on the Mac (which could handle encryption in a local Mac environment) and the secure erase the files on the PC. If I did this, could I send the files unencrypted (since https will encrypt them while they are on the internet)?</div>
<div><br></div><div>True Crypt appears to be close to what I want, but it is discontinued. I don't know if I could use something like gpg, since I don't have admin privileges on the PC.</div><div><br></div><div>-Dan</div>
