+ *                  254 for Curve25519 or 447 for Curve448.
+ * \param d         The randomly generated key. This is a number of size
+ *                  exactly \p n_bits + 1 bits, with the least significant bits
+ *                  masked as specified in [Curve25519] and in [RFC7748] §5.
+ * \param f_rng     The RNG function.
+ * \param p_rng     The RNG context to be passed to \p f_rng.
+ *
+ * \return          \c 0 on success.
