Data submitted from HTTP to HTTPS: is it encrypted?

Question

4.50/5 (2 votes)

I have a form on an unsecured website (HTTP.) When the user clicks Submit, data is POSTed to a secure website (HTTPS.)

Is the data encrypted?

In other words, does encryption depend on the protocol of the current page, the URL to which the data is being submitted, or will it always be encrypted if one of the two sites is using SSL?

I know, I know, the obvious solution would be to secure the first site. Unfortunately, that is not an option at this time.

No, it's not encrypted when you send the initial POST request. The response from the server to that request will setup the encryption session and everything after that will be encrypted, so long as it stays on HTTP.

That's what I thought would be the case, thanks for the information.
