Isabelle’s Lazy Message Protocol

network packet protocol

I don’t know whether or not this is a super practical way of doing things but I’m lazy and it seems to work so gonna roll with it lol

segment size	usage
1 byte	u8 packet kind
1 byte	u8 encrypt flag
8 byte	u64 length of the packet contents
4 byte	CRC32 packet contents checksum
32 byte	SHA256 packet contents integrity check
u64::MAX	packet contents

packet kind

packet kind has defined values for packets but leaves many open for user defined packets to be added to the protocol

byte	packet kind
0x00	message - a simple text packet
0xfe	join - announces a new connection
0xff	agreement - used to help generate an aggreed upon key

encrypt flag

encrypt flag can be 0x00 for no encrypt or 0xff for ring AEAD symmetric encrypt
