is in secp256r1. I already know the parameters $a$ and $b$ of the curve, but they are pretty big and they are in hexadecimal. I've been trying to pass it to decimal, but I'm not getting it. Should I compute it in hexadecimal? I do also don't understand what are the coordinates of the public key. I mean, public key is supposed to be a point with x-coordinate and the least important part of the y-coordinate, as public key begins by 04, isn't it? I'm really sorry, but I'm confused about how to approach this. Thanks.

Note: I saw some questions that were basically the same as mine, but the numbers were much smaller. I do also have PARI/GP to use. Thanks
