+/** Generate a private key on a Montgomery curve (Curve25519 or Curve448).
+ *
+ * This function implements key generation for the set of secret keys
+ * specified in [Curve25519] p. 5 and in [Curve448]. The resulting value
+ * has the lower bits masked but is not necessarily canonical.
+ *
+ * \note            - [Curve25519] http://cr.yp.to/ecdh/curve25519-20060209.pdf
+ *                  - [RFC7748] https://tools.ietf.org/html/rfc7748
+ *
+ * \p n_bits        The position of the high-order bit of the key to generate.
+ *                  This is the bit-size of the key minus 1:
+ *                  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.
+ * \return          \c MBEDTLS_ERR_ECP_xxx or MBEDTLS_ERR_MPI_xxx on failure.
