Windows: We've shown you how to add a second layer of encryption to Dropbox, but if you're looking for a simpler way to secure your synced files, free app SecretSync encrypts any Dropbox files you want before sending them to the cloud.Dropbox already encrypts the files you sync to its servers, but we recently learned that certain employees at Dropbox — or the government, if they wanted to — could come in and unencrypt those files. To avoid this, you have to encrypt things on your computer before sending them to Dropbox. That's where SecretSync comes in.
SecretSync is incredibly easy to use: It adds another folder on your hard drive, where you can place sensitive information that you want encrypted before being sent to Dropbox. It will encrypt everything in that folder with 256-bit AES encryption, using a key to which only you have access. Then, your files are decrypted on any other computers on which you have SecretSync installed. You can't open those files from the Dropbox web interface, nor could anyone at Dropbox unencrypt those files and view them.
Of course, this doesn't keep them secure from people that get a hold of your computer, but it's an insanely easy way to add a little second layer of encryption to files that you're syncing to the cloud.
Right now, SecretSync is in closed beta,
