![]() ![]() 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.
