Boxcryptor

Boxcryptor is an easy-to-use encryption software optimized for the cloud. It allows the secure use of cloud storage services without sacrificing comfort. Boxcryptor supports all major cloud storage providers (such as Google Drive, Microsoft OneDrive, Dropbox, iCloud) and supports all the clouds that use the WebDAV standard (such as Strato HiDrive, Box and ownCloud). With Boxcryptor your files go protected to your cloud provider and you can enjoy peace of mind knowing that your information cannot fall into the wrong hands.

Boxcryptor creates a virtual drive on your computer that allows you to encrypt your files locally before uploading them to your cloud or clouds of choice. It encrypts individual files - and does not create containers. Any file dropped into an encrypted folder within the Boxcryptor drive will get automatically encrypted before it is synced to the cloud. To protect your files, Boxcryptor uses the AES-256 and RSA encryption algorithms.
