- Dropbox files at rest are encrypted using 256-bit Advanced Encryption Standard (AES).

- Dropbox uses Secure Sockets Layer (SSL)/Transport Layer Security (TLS) to protect data in transit between Dropbox apps and our servers; it's designed to create a secure tunnel protected by 128-bit or higher Advanced Encryption Standard (AES) encryption.

But don't they provide the "I forgot my password" option?? Doesn't that mean tjey have enough info to decrypt your data whenever thy want to, let you change your password, and encrypt it again with that new one??? Looks like the same problem to me in the fact that any Dropbox worker can take anything you upload. Moreover, Condoleza Rice hired??! Wtf.
