+# How it works
+### HTTP
+Since most of websites in the world now support HTTPS, SpoofDPI doesn't bypass Deep Packet Inspections for HTTP requets, However It still serves proxy connection for all HTTP requests.
+
+### HTTPS
+ Although the HTTPS requests are encryted with TLS, the domains are still shown as plaintext in the encryted requests. 
+ In other words, when someone else looks on a packet, they can easily identify where the packet is headed to.
+ I had tried some ways to bypass the inspections, and found out that only the first chunk is inspected when we send the encryted request in chunks. 
+ What SpoofDPI does to bypass this is to send the first 1 byte of a request to the server, 
+ and then send the rest.
+ > SpoofDPI doesn't decrypt your HTTPS requests, and that's why we don't need the SSL certificates.
