/*-

* 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).
