I like Encfs however for cloud syncing files sometimes just a simple 7zip aes will suffice esp if sharring to more or less

CryptSync is a small utility that synchronizes two folders while encrypting the contents in one folder. That means one of the two folders has all files unencrypted (the files you work with) and the other folder has all the files encrypted.

The synchronization works both ways: a change in one folder gets synchronized to the other folder. If a file is added or modified in the unencrypted folder, it gets encrypted. If a file is added or modified in the encrypted folder, it gets decrypted to the other folder.

This is best used together with cloud storage tools like SkyDrive, DropBox or Google Drive.

If you want to use such cloud storage for backups, it's a good idea to keep your private data really private. That means only uploading encrypted files to make sure no one else can access your data. Because even if the companies behind the cloud storage guarantee your privacy, it's always possible that your account gets hacked: so make sure you use a different password to encrypt the data with CryptSync than you use to login to yourcloud storage provider!

If you want to backup and encrypt your files to more than one cloud storage (just to be safe), you can do that as well: just set up two sync pairs with the original folder being the same for both pairs.

CryptSync works by synchronizing folder pairs. One folder is called the original folder: that's where your unencrypted files are stored and where you work with your files. The second folder of such a pair is theencrypted folder which is where the files get copied from the original folder and encrypted. The encrypted folder is usually located somewhere inside your cloud storage sync folder.

The encryption is done using 7-Zip, which also compress them at the same time. That means you not only get encryption but also compression for free, which reduces the storage space you use in the cloud.

That also means that if you ever need to access your encrypted files directly from the cloud, you can save them locally and just open them with 7-Zip or other compression tools. Of course you'will then be asked to provide the password you used with CryptSync to open that file.

When you first start CryptSync, the main dialog is shown where you have to set up the folders to synchronize.

To add a folder pair, click on the button and then enter the paths to both folders. Then enter the password that will be used to encrypt and decrypt your files.
