Reliability Layer

[Qndre]

How do I encrypt a reliable packet?

"packet" contains the UNENCRYPTED packet which should be sent reliable

"reliableheader" contains the "0x0003 + ACKID"

"encrypt(packet)" is a pseudo-function which gives the encrypted value of "packet" back

 

reliableheader + packet
--- OR ---
encrypt(reliableheader) + packet
--- OR ---
encrypt(reliableheader + packet)
--- OR ---
reliableheader + encrypt(packet)
--- OR ---
encrypt(reliableheader + encrypt(packet))

#3 or #4, I'm not sure which.

You encrypt it just like any other packet.

From memory, you would leave the type byte (0x00) unencrypted and encrypt the rest.

 

You really should be looking at other source code to find this for yourself...

The game type byte is left plain too?

I couldn't remember if that was the case

00 03 Rest Encrypted

So it's

encrypt(reliableheader + packet)

not

encrypt(reliableheader + encrypt(packet))

?

PS: Reliableheader is 00 03 + ACKID; encrypt() function lets first byte unencrypted if game and first two bytes if core.

[»nintendo64]

if so

 

PS: Reliableheader is 00 03 + ACKID; encrypt() function lets first byte unencrypted if game and first two bytes if core.

 

then

 

encrypt(reliableheader + packet)
