Are HTTPS headers encrypted

Question

When sending data over HTTPS  I know the content is encrypted  however I hear mixed answers about whether the headers are encrypted  or how much of the header is encrypted   How much of HTTPS headers are encrypted   Including GET POST request URLs  Cookies  etc

User · Answer

the URL is also encrypted  you really only have the IP  Port and if SNI  the host name that are unencrypted

HTTPS  HTTP over SSL  sends all HTTP content over a SSL tunel  so HTTP content and headers are encrypted as well

User · Answer

With SSL the encryption is at the transport level  so it takes place before a request is sent   So everything in the request is encrypted

User · Answer

The headers are entirely encrypted  The only information going over the network  in the clear  is related to the SSL setup and D H key exchange  This exchange is carefully designed not to yield any useful information to eavesdroppers  and once it has taken place  all data is encrypted

HTTP version 1 1 added a special HTTP method  CONNECT - intended to create the SSL tunnel  including the necessary protocol handshake and cryptographic setup  The regular requests thereafter all get sent wrapped in the SSL tunnel  headers and body inclusive

New answer to old question  sorry   I thought I d add my   02  The OP asked if the headers were encrypted   They are  in transit   They are NOT  when not in transit   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   Server logs on the remote end can also contain querystring as well as some content details   Also  the URL isn t always secure  the domain  protocol  and port are visible - otherwise routers don t know where to send your requests   Also  if you ve got an HTTP proxy  the proxy server knows the address  usually they don t know the full querystring   So if the data is moving  it s generally protected   If it s not in transit  it s not encrypted   Not to nit pick  but data at the end is also decrypted  and can be parsed  read  saved  forwarded  or discarded at will   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    Also  cookies are not encrypted under the HTTPS protocol  either   Developers wanting to store sensitive data in cookies  or anywhere else for that matter  need to use their own encryption mechanism   As 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   So if you re worried about packet sniffing  you re probably okay   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

The whole lot is encrypted    - all the headers  That s why SSL on vhosts doesn t work too well - you need a dedicated IP address because the Host header is encrypted      The Server Name Identification  SNI  standard means that the hostname may not be encrypted if you re using TLS  Also  whether you re using SNI or not  the TCP and IP headers are never encrypted   If they were  your packets would not be routable
