Just share from noob
. Ecc just processing in cyclic only from even Pvkey/Pubkey. We have two option in doubling (0) or doubling part of addition (1), if N number can derived to pubkey we can make sure which one is odd and even and continue derived bit by bit to define Pvkey..but until now this is impossible because range must be N-1 that why higher Pvkey must be substract with N, maybe waiting man with Einstain brain to manipulating curve and found the backdoor.Thank for Albert0bsd for the ecctools
