Otherways nowadays it's impossible to get it. This is the same as saying on RSA that you can only get the message if you know the Sk. because discrete logarith is so hard to solve. Also, tell you that the Pk and Sk are points of the eliptic curve. From here is where pairings and other ZkSnarks main components are born. Here you have good lectures to learn about that. | |
