Tor works in such a way that the data is encrypted by the three nodes. I.e., the entry node, relay and the exit node. But why is it not encrypted from the exit node to the destination server? Is this for speed? Or is it because it's not necessary as tracing back is already impossible?

    How would it negotiate the encryption with the server? Unless you are talking about TLS which is effectively at a different layer.

  • The client can use the destination server's public key to encrypt right?

    Which public key? What protocol are you talking about?

  • Even when the user requests http://example.com/ and some proxy determines that https://example.com/ also exists, there is no guarantee that it's the same site with the same content served securely.

Encryption of traffic exiting Tor and going to the destination server is based on whether the destination server supports encryption, and whether the destination server was addressed on an encrypted port - just as it would be had the traffic not gone through Tor.



Tor cannot magically do something the destination server doesn't support, or that the client did not request to do.

            How many registers does an x86_64 CPU actually have?

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers.
