the flag "comp" is not required. See in the tests/t-cv25519.c line +- 176.
Futher hwo do you create the shared secret k. This is described in
4.3 Shared secret generation.
It goes via scalar multiplication of the "other side's public key and the
local private key scalar".
Both are available, but scalar multiplaction of q_s and d_c?
