Thank you for your answer. What is nonces ?
I need them for tests and I need know nonces...

121 bit : 3 r,s,z use LLL_nonce_leakage.py , you can found private key about 1~2 second

Thank you !!!! Wink

But, no logic with so big nonce, can you generate rsz with nonce 2**30 or less for ex to ,120 puzz pubkey ?

Oh, your rsz is work in my scrypt
