Update on August 4, 2013: The Fogpad site was unavailable for several hours today, but as of 9:30 p.m. The files are encrypted on the client PC before being uploaded automatically to your Google Drive account. With Fogpad, you create and edit text files via a basic online word processor. I recently discovered two free services that take different approaches to online encryption. In last May's ' Free services make Gmail, Google Drive, and Google search more private,' I described the BoxCryptor program that adds an encrypted folder to Google Drive. I could have easily encrypted the files using any number of free services.

That hasn't prevented me from uploading plenty of sensitive information to Google Drive, including dozens of invoices that list my address and the amount of money I was billing for, although the invoices do not include any bank-account or Social Security numbers. I've been aware since the beginning that the thousands of files I have uploaded to the service are stored unencrypted on Google's servers. This month marks the sixth anniversary of my Google Drive account.
