In the case of HTTPS, HTTP is the application-layer, and TCP the transport-layer. To understand, what is encrypted and what not, you need to know that SSL/TLS is the layer between the transport-layer and the application-layer. But if you're worried about malware or someone poking through your history, bookmarks, cookies, or cache, you are not out of the water yet. So if you're worried about packet sniffing, you're probably okay. Developers wanting to store sensitive data in cookies (or anywhere else for that matter) need to use their own encryption mechanism.Īs to cache, most modern browsers won't cache HTTPS pages, but that fact is not defined by the HTTPS protocol, it is entirely dependent on the developer of a browser to be sure not to cache pages received through HTTPS. And, malware at either end can take snapshots of data entering (or exiting) the SSL protocol - such as (bad) Javascript inside a page inside HTTPS which can surreptitiously make http (or https) calls to logging websites (since access to local harddrive is often restricted and not useful).Īlso, cookies are not encrypted under the HTTPS protocol, either.
Not to nit pick, but data at the end is also decrypted, and can be parsed, read, saved, forwarded, or discarded at will. If it's not in transit, it's not encrypted. So if the data is moving, it's generally protected.

Server logs on the remote end can also contain querystring as well as some content details.Īlso, the URL isn't always secure: the domain, protocol, and port are visible - otherwise routers don't know where to send your requests.Īlso, if you've got an HTTP proxy, the proxy server knows the address, usually they don't know the full querystring. So, your browser's URL (and title, in some cases) can display the querystring (which usually contain the most sensitive details) and some details in the header the browser knows some header information (content type, unicode, etc) and browser history, password management, favorites/bookmarks, and cached pages will all contain the querystring. The OP asked if the headers were encrypted.
