Encrypting online folders

I have an ftp folder with several subfolders whose contents change occasionally. I would like to encrypt the entire folder structure online, without having to re-upload the entire folder if its contents have changed. Is there a way to easily encrypt a folder that resides on an ftp host, and which software could do it? Thanks for any input.

 

If I understand what you're trying to achieve, a better solution might be to keep your "folder structure" a TrueCrypt folder, so when you close it -you know the contents are encrypted. You then backup the TC file (which if it's text-only could be as small as a few MB). Google TrueCrypt and DropBox for example. But like Poosey, I'm a little confused about what you're wanting to achieve in the end.

 

You could use one of the services that provide online encrypted storage. If you want more oversight, you'll need a host that allows you to run encryption software on their server.

 

Thanks for your answers, and my apologies for being unclear.

I have an online folder with several subfolders containing scanned documents that I would like to synchronize with an offline folder occasionally. The entire folder is about 1 GB, so uploading a Truecrypt file is very cumbersome.

If possible, I would like to find a solution that lets me use my own host.

I would also like to be able to view the files online (without downloading), as I sometimes access them from hotspots, so the solution should be able to encrypt/decrypt on the fly.

Thanks for any more leads!

 

Thanks, I will look into it. A VPN may solve the whole issue. The ideal solution would be a software like axcrypt installed directly on the server.

 

Based on their reputation and the fact that files uploaded to dropbox get encrypted when stored on their server, do you feel that is safe enough without the need to pack them in truecrypt??

Thanks!

 

Second Copy might be an option to consider, since it can encrypt new or updated files on your PC and send the encrypted ZIP versions via FTP to a server.

Personally, I don’t use Second Copy – but, it appears to have a good reputation.
