iPad DropBox client side encryption I have just gotten the New IPad - my first foray into the world of Apple.  I'm eager to make the most of it that I can, for both personally and for work.

In order for me to be able to use it for work, I really need to find a solution that works seamlessly with DropBox to provide client-side encryption for my files.  

Despite searching for hours (days) and downloading and trying all manner of offerings, I just can't find anything that works.  The closest I've seen so far is BoxCryptor, but that only works if I manually upload the file via the BoxCryptor client.  I want something that will work seamlessly so that Notebooks (or EverNote, etc) think they're using DropBox directly, but the files are being encrypted / decrypted just before they enter or leave DropBox.

Any clues?

I use a program called 1Password for secure encryption of files (and other data) and it almost does what you ask. 

On my Mac client - it can attach arbitrary files to any entry and securely encrypt them before they get stored into Dropbox, but that isn't the primary purpose of the tool. It has an iOS client that can see files attached in this manner, but not really open them, send them to other programs and it also doesn't let you file things.

So - what you ask is clearly something that could be programmed, but isn't something where there are several well-known solutions and people will just propose several. In fact, there may not be a single solution that uses Dropbox despite how popular and prevalent it has become.

I would suggest you consider Box.net which seeks to be a more enterprise secure version of Dropbox - especially if no-one else has a better suggestion than mine for securing your files before they hit Dropbox.
