I was change a N from order.SetBase16("FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364141") to 2^70

I divide 0xf56926f9ca9abc1065153d25383e80 / -1
Result: 20212ef8c52b3a842d0bc

but then I divide pubkey from

0xf56926f9ca9abc1065153d25383e80 - privkey;

bupkey are differents, but must be pub1  = pub2 !!!

how to resolve this ?

ASAP.

0xf56926f9ca9abc1065153d25383e80 is a 116-bit private key, which out of range for n. What's more, you're dividing it by -1 so it calculated -0xf56926f9ca9abc1065153d25383e80 instead. This is still not in range, so it'll keep adding N (2^70 = 1??) to this number until it is within range, hence mod(-0xf56926f9ca9abc1065153d25383e80, n) = 20212ef8c52b3a842d0bc <-- this is a 70-bit private key.

When you attempt to make a public key it interprets the input as 256 bits. So if you want to avoid that, you must insert the modulus first.

Hi bro.

How to calculate this for publick key

Hi bro.

How to calculate this for publick key

Doesn't ecctools have a "mod" command? (I have never used ecctools before).

[bigvito19]

Its an error in the code he hasn't changed yet. I already told him about it and he told me you can do that with bash or python.

Bro, can you make python function ?

pls


I wasvchange a Order, in keymath, modmath and generatecfrom privkey.

Then div pubkey, and dividing privkey (resul for ex will be Z, result are different ! resulted pubkey not from  Z !!!

How to solve this ptoblem ??

why modulus ?


i need change order, not midulus ?

Thank's

[NotATether]

Thank's

Because you cannot change the curve order when generating a bitcoin public key. Otherwise you will end up with an invalid key. So that's why you hace to modulus the private key first before you compute the public key.

Can you make script please ?

yes, result is "invalid" but this is ok.

Hello. Bro, did you find any alternaative formulas for dividing and creating  privkeys and pubkeys ?

That code above is not exactly for dividing pubkeys, that code is for showing the address of that pubkey. This is a code for dividing pubkeys
