The +information gained - the **Common Name** and **Subject Alternative Names** - is +then used to generate the interception certificate, which is sent to the client +so the connection can continue. + +This rather intricate little dance lets us seamlessly generate correct +certificates even if the client has specified only an IP address rather than the +hostname. It also means that we don't need to sniff additional data to generate +certs in transparent mode. + +Upstream cert sniffing is on by default, and can optionally be turned off. + +================== ============================= +command-line :option:`--no-upstream-cert` +mitmproxy shortcut :kbd:`o` then :kbd:`U` +================== ============================= |
