Types

type Amnezia 

type Amnezia struct {
	Jc, Jmin, Jmax uint16 // unused: junk packet count, min, max

	S1, S2         uint16 // handshake init/resp pkt sizes
	H1, H2, H3, H4 uint32 // modified msg types [4]byte
	// contains filtered or unexported fields
}

Jc (Junk packet count) - number of packets with random data that are sent before the start of the session Jmin (Junk packet minimum size) - minimum packet size for Junk packet. That is, all randomly generated packets will have a size no smaller than Jmin. Jmax (Junk packet maximum size) - maximum size for Junk packets S1 (Init packet junk size) - the size of random data that will be added to the init packet, the size of which is initially fixed. S2 (Response packet junk size) - the size of random data that will be added to the response packet, the size of which is initially fixed. H1 (Init packet magic header) - the header of the first byte of the handshake H2 (Response packet magic header) - header of the first byte of the handshake response H4 (Transport packet magic header) - header of the packet of the data packet H3 (Underload packet magic header) - UnderLoad packet header."
