 This creates a fresh context of type `EVP_PKEY_KEM` and sets the specific KEM parameters (Kyber512 in this example). The context is now ready for key generation (`EVP_PKEY_keygen`). However, the context created in this way doesn’t have an associated key (`EVP_PKEY`), so obviously, we can’t encapsulate/decapsulate with it. Therefore, this is useful for key generation only, i.e. before we have a key.
