Title: Re: elliptic curve division Post by: digaran on February 08, 2023, 09:21:54 PM You just multiplied and divided the same values which will always return as same, 1 and -1, do you think you could play my game now? What is the smallest public key and largest public key? And could we somehow organize them alpha numerically? That way you'll have a map to the entire public key database and then represent them with decimal even hexadecimal values. Mind blowing I know, maybe your username could be used as a reference to me.🤣

sibstract is same as divide, and without float Title: Re: elliptic curve division Post by: ymgve2 on February 09, 2023, 03:03:19 AM ecdsa123's point is you did the math wrong, one will always be 02 and one will always be 03, when you get two equals you messed up the math.

yes i tested ecctools and python ecdsa lib and some other lib, and found mistakes in my scripts useing fastecds lib in python i think this thread is useless, pls advice to MOD for delete this or archive it, for save others time to read and test uselss topic |
