think I misunderstand Boxcryptor, and I just want to check my knowledge. My understanding is that Boxcryptor encrypts everything inside an encrypted directory on Dropbox. That is, I make a directory on Dropbox, set it to "encrypt," and everything I put in that document becomes encrypted. If I move it outside that directory, it remains encrypted. If I copy/paste that document into a local non-cloud drive, it remains encrypted. If I attach a document from that directory without decrypting, I will send an encrypted document.
This doesn't seem to match reality. I sent a file by email as a test, and the receiver said it wasn't encrypted. If I copy/paste a file to another Dropbox directory, it remains encrypted. If I copy/paste it to outside my Dropbox directory, it becomes unencrypted.
If that's the case, what's the purpose of Boxcryptor? It is just encrypting things on Dropbox. Presumably, someone could hack my account and just copy/paste the document to access it, no? What am I missing?
