When you store a file, it is first encrypted on your computer and then chunked up and encoded into redundant fragments using erasure codes (Reed-Solomon codes). These encrypted, redundant fragments are then stored in our European data centers and in the Wuala cloud. We make sure that your data is always safe. A complete backup of your encrypted files is always kept on our servers, so that it can always be accessed and restored. The Wuala cloud serves as an optimization that allows us to operate a large-scale infrastructure at low cost and to provide you with better performance. Also, it allows organizations to get access to reliable online storage by providing their own resources to the Wuala cloud.
Wuala protects your privacy: In stark contrast to most other online storage services, all your files get encrypted on your computer, so that no one - including the employees at Wuala and LaCie - can access your private files. Your password never leaves your computer.
Wuala employs the 128 bit AES, 2048 bit RSA and SHA-256 algorithms for encryption, signatures and integrity checks. If you're interested in how Wuala manages encryption, have a look at our publication on Cryptree.
