How does CloudBackup encrypt my files?
CloudBackup encrypts files prior to uploading them using 256-bit AES. AES is an industry (and government) standard and is one of the most well studied and most secure encryption algorithms available. CloudBackup uses a unique key for each file, and constructs the key using a HMAC that helps protect against certain attacks. The master key is based on a password you choose which is known only to you and not stored with CloudBackup.
