Let’s first calculate the discriminant :

WebOne approach to obtaining prime numbers in instantiations of these cryptographic primitives is to produce such numbers as they are needed on whatever device requires them. This is accomplished by sampling random integers and checking for primality. This process can be computationally intensive to the point of being prohibitively so.
