+ * Computes the multiplicative inverse of x in the range
+ * [1,EC_GROUP::order), where EC_GROUP::order is the cardinality of the
+ * subgroup generated by the generator G:
+ *
+ *         res := x^(-1) (mod EC_GROUP::order).
+ *
+ * This function expects the following two conditions to hold:
+ *  - the EC_GROUP order is prime, and
+ *  - x is included in the range [1, EC_GROUP::order).
+ *
+ * This function returns 1 on success, 0 on error.
+ *
+ * If the EC_GROUP order is even, this function explicitly returns 0 as
+ * an error.
+ * In case any of the two conditions stated above is not satisfied,
+ * the correctness of its output is not guaranteed, even if the return
+ * value could still be 1 (as primality testing and a conditional modular
+ * reduction round on the input can be omitted by the underlying
+ * implementations for better SCA properties on regular input values).
