PDF data encryption





I have a PDF form which will be available over a public website for users to download and fill their information. Upon filling and clicking the Submit, the PDF will invoke my servlet which is deployed on Websphere Server. Is the data transmission from users desktop to the Servlet Encrypted? If so, what level of encryption that adobe provide? If not, how do we encrypt this data transmission for PDF to the Servlet? Appreciate your response.

I have the following setting for the Submit button:

Submit as URL encoded HTTP POST, UTF 8.
