Can you trust your favorite cloud storage site with your most private stuff? The answer is yes sort of. Google Drive and MS OneDrive are both very popular cloud storage sites. They both secure your data with AES 256bit encryption (very secure) during transfer and while it sets on their servers. The problem is you don’t control the keys, they do. Google and Microsoft both have protocols to prevent unauthorized access to your files and will only relinquish your if forced to by law enforcement.
If there is some data you really need to keep secret you need to encrypt it first. That’s where Boxcryptor comes in. Boxcryptor will encrypt your files then upload them to the cloud storage service of your choice. Google Drive, Skydrive, Box, Dropbox, Amazon S3, SpiderOak, SugarSync and many more.
