As far as I understand, it is possible to send encrypted data over unencrypted network protocols, such as HTTP; however, it would look really suspicious if encrypted data were sent through an unencrypted network. So, I was thinking about encrypting the data (a text file, for instance) locally and then send it through HTTP. Now, my question (or questions) is:
If someone were to inspect the data sent over the network, would they know that it was encrypted? If so, what would be a way to make the encrypted data look like unencrypted data (for example, if the text said: "Hello World," the intruder would read something like: "Not a secret")
Please, correct me if I haven't quite understood how encryption works as I have no real experience with it besides encrypting my hard drive.
