Hi,

The initial NIST KEM API description was perhaps little too terse for me.

I am assuming that the appropriate mapping for key exchange purposes
would be as follows (looking at:
https://github.com/open-quantum-safe/liboqs/blob/master/src/kex/kex.h
)

Function: alice_0() = crypto_kem_keygenerate()
alice_priv = sk
alice_msg = pk

Function: bob() = crypto_kem_encapsulate()
alice_msg = pk
bob_msg = ct
key = ss

Function: alice1() = crypto_kem_decapsulate()
bob_msg = ct
alice_priv = sk
key = ss

Cheers,
- markku
