Summary	0008622: TCP and UDP communicator symmetric encryption
Description	We should update our encryption scheme for the baseline encryption. Currently, we use an AES/Twofish double encryption. Instead, I propose we use a more standard KDF with XSalsa20 (or ChaCha) as stream cipher, probably with Poly1305.
Additional Information	Probably protocol breaking and considered 0.22
Tags	No tags attached.
