Easily Encrypt and Secure Your Cloud Data
How it works
Here is how to make it work in 3 steps on Windows.
1. Download the Windows version of client and install it on your Windows.
2. Launch it the first time, and sign up an account with Viivo.
Viivo – Login Screen
3. Once the account is created and signed in, Viivo will create a folder called Viivo under userprofile, just like Dropbox and SkyDrive, and automatically associate another folder called Viivo-Encrypted that saves the encrypted version of everything stored in original Viivo folder, with .viivo extension name. See Figure 1 and 2 below.

Figure 2 – the encrypted Viivo folder in Dropbox
Now, when you need to save a sensitive file over to Dropbox, simply save it into original Viivo folder and it will automatically put an encrypted copy in Dropbox for you. The Explorer integration is also enabled to allow you to copy/move data right from the right-click context menu. How easy is that?

The step 2 described above is actually quite important. Make sure you are using a valid email address with a complicated password. The sign-up process can only be done on the desktop client so no information would be exposed to either Internet or even the people working for Viivo. It’s part of their security design to make sure all user information are saved in a way that cannot be decrypted by anyone other than the original owner.
The password will also be used to generate the private key for AES-256 encryption using PBKDF2 HMAC SHA256. And all files saved with Viivo will be encrypted with the same AES-256 encryption.
If everything works based on these facts, it’s fairly safe at my view.
