![]() ![]() This means that a user who knows her password, can generate the outer level encryption key using PBKDF2 and the salt, then decipher the outer level keys, and be on the way to decrypting her data. This approach prevents brute force and pre-computation or database attacks against the key. They are encrypted with 256 bit AES, using a key created by the key derivation/strengthening algorithm PBKDF2 (using sha256), with 16384 rounds, and 32 bytes of random data ("salt"). Most importantly, however, the outer level keys are never stored plaintext on the SpiderOak server. SpiderOak uses a combination of 2048 bit RSA and 256 bit AES to encrypt your files. If you're looking for a secure option that stores your files in an encrypted form but doesn't sacrifice usability, SpiderOak is definitely worth a look. When your remote session is over, they destroy your password, so you can be comfortable that you're the only person who can access your files. The encryption and decryption process still takes place locally, but the only thing that's stored on SpiderOak's servers are your password, so they can authenticate you and direct you to the right files. In the past, SpiderOak limited its remote access and syncing options, but SpiderOak Hive, their new syncing service, along with their iOS and Android apps let you take your encrypted files on the go. ![]() At the same time, this also means that if you lose your password, SpiderOak can't retrieve it-or decrypt your locked files-for you. Also, since your data is encrypted locally with a password you choose, they have absolutely no way of decrypting it to see what's in your data store. The only unencrypted versions live on your local computer. Essentially, your data is completely private because you're the only person who knows what's being encrypted and transmitted. SpiderOak's "Zero Knowledge" privacy policy notes that because the encryption process takes place locally, they have no way of knowing what you're storing with them. All of your files are encrypted locally on your computer, and then uploaded to SpiderOak's servers, and any changes you make to your files and folders are synced with the local decrypted versions before being secured and uploaded. SpiderOak starts you off with 2GB for free, with more storage available at $10/mo for each additional 100GB you need. The internet is aflame with the news that the National Security Agency may be spying on phone calls Read more SpiderOak if you would like to store files of 50GB, you’d have to make 50GB available on your own hard-disk.What the NSA Spying Scandal Means for You Furthermore, in order to use more than 1GB of storage you need to make the same amount of space available on your own hard-disk, for sharing over the network. The downsides are that you need the application installed to access your files, and this may be a problem when you are not at home or in the office. All the files you store are set as private by default but if you need to share them with your friends, groups or with the whole network, you can do that easily by changing their availability. The program in itself is highly usable and has a pleasant design. Thanks to a multi-download system (as bytes of your files are located on different PCs of the network), you will access your files quickly. Based on P2P technology, it stores encrypted versions of your documents around the Wuala network, so that they will always be available to you with no risk of server breakdown. ![]() Wuala is an online drive, accessible from anywhere. ![]()
