One of the biggest concern when using those popular online storage service like Dropbox, Box.net, or SkyDrive is the privacy. No matter what claims the service providers put upfront, the truth of the matter is that once the data is gone to the cloud you lost full control of it. The only way to protect private belongings while still using these awesome services is to safely encrypt them before storing them to the cloud. But unfortunately, none of these popular services have the encryption option out of the box.
Cloudfooger is an encryption solution that can be used as a mid-ware to bridge this situation, encrypt your data before uploading them to the cloud. It offers a windows desktop client that you can download and install on your Windows system, free of charge for non-commercial use.
Once it’s installed, you can simply encrypt any type of files right from the right-click context menu in Windows Explorer, and decrypt them in the same way.
You can also mount a specific folder as a driver to use on-the-fly encryption. Any file dropped in that drive will be automatically encrypted. And that’s how you can configure to automate the encrypt process to secure the data before storing them to the cloud.
For example, if the folder you specify is a Dropbox folder, all files you drop to your Dropbox will be encrypted on-the-fly before snyc’d to the cloud. And this applies to almost all cloud storage provider, or even your local network/disk storage.
However, using Cloudfogger to encrypted data for cloud storage has a big obstacle to overcome. In order to decrypt and use the encrypted data on another devices, you need to install Cloudfogger program with the same username and password. Since Cloudfogger doesn’t seem to have a client for a platform that is not Windows and an mobile app for smartphone, you won’t be able to decrypt and use the data on these devices. It’s extremely useful when you exclusively use Windows.
Cloudfogger encrypts all your files using AES, a method approved by NSA for top secret information. So your data can be considered top secure once encrypted by Cloudfogger.
Sharing Cloudfogger-protected data is also possible in a few ways but I won’t recommend using it at this stage since I found it’s not so intuitive to use sharing method with encrypted data.
