 As of this time (Oct 2018) Kyber is one of the candidate algorithms submitted to the [NIST post-quantum cryptography project](https://csrc.nist.gov/Projects/Post-Quantum-Cryptography). The authors recommend using it in "... so-called hybrid mode in combination with established "pre-quantum" security; for example in combination with elliptic-curve Diffie-Hellman." THIS PROJECT DOES NOT DO THIS (in case you didn't notice yet, THIS PROJECT IS EXPERIMENTAL.)
