Supports major cloud services
Boxcryptor has released an OS X client for its self-titled encryption software. The tool is used to encrypt files before uploading them to a cloud storage service, such as Dropbox, Google Drive, SkyDrive, Box, or SugarSync. Using Boxcryptor's apps for various platforms, including iOS and Android, the files can be decrypted and accessed elsewhere.
A free tier includes RSA/256-bit AES encryption, filesharing support, and use of both desktop and mobile clients. Subscribers have to upgrade to a $48-per-year Unlimited Personal account for access to filename encryption and an unlimited number of providers and devices; free accounts can only be linked to one cloud service and two devices. The Unlimited Business tier costs $96 per year, but supports user groups and is required for commercial purposes. Also available are Company Packages with master keys, password resets, and enforceable policies.
