-snip-
Are you sure you are using the correct s and z in the second equation? You say you have k, and you should only have one r value if k is being reused, so it should simply be a case of taking s2 and z2 and using them to calculate the second private key.


strange...no error
11  Bitcoin / Development & Technical Discussion / Re: same-r-value-is-used-for-two-different-addresses on: October 31, 2022, 11:04:57 AM
yes correct
i have recovered privatekey address 1
but i can't recover privatekey address 2...
If you have the private key for the first transaction, then you can calculate the k value as follows, where x is the private key:

k = (z1 + r1*x1)/s1

Once you know k, which you say is reused in the second transaction, then you can just rearrange the equation above to calculate the private key for the second transaction:

x2 = (k*s2 - z2)/r2

first of all..thanks for your help
 i have done equation
i have k
i have that x1 = x2
than i have only privatekey address 1
it's very strange
12  Bitcoin / Development & Technical Discussion / Re: same-r-value-is-used-for-two-different-addresses on: October 31, 2022, 10:42:51 AM
i have 2 addresses that have same R value
I assume by this you mean you have two transactions which are sending coins from two different addresses but use the same r value.

The answer in that case is you cannot recover the private keys. To do this you need at least two transactions which are using the same private key and reuse the same r value. You cannot use two transactions with different private keys but the same r value.

yes correct
i have recovered privatekey address 1
but i can't recover privatekey address 2...

m1   scalar:0x......................
m2   scalar:0x......................
r   scalar:0x.......................
s1   scalar:0x......................
s2   scalar:0x.......................
k   scalar:0x.......................
x1   scalar:0x = to x2
x2   scalar:0x = to x1

i have checked this old post
https://bitcoin.stackexchange.com/questions/37673/same-r-value-is-used-for-two-different-addresses-finding-z1-and-z2-value-and-pr
and have recovered privatekey 1 and privatekey 2
13  Bitcoin / Development & Technical Discussion / same-r-value-is-used-for-two-different-addresses on: October 31, 2022, 09:54:26 AM
hi all
i have 2 addresses that have same R value
address 1         same R
address 2         same R
i know R
i know S1    and S2
i know M signed message or Z    M1   and  M2
When a signing secret was used to sign two different messages, you can recover the signing secret with this calculation:
 k = (m1-m2)/(s1-s2)
the problem is that i can recover only privatekey of 1 address
i have need of recover privatekey address 2
what is correct formula  for recover the privatekey of address 1   and address 2 that have same R used in 2 different address?

thanks for your help

i don't know to do that...sorry
15  Bitcoin / Development & Technical Discussion / Re: Help Get RZS value error ....OFFER BOUNTY IF RECOVER BTC on: October 11, 2022, 08:15:05 PM
i know R and S
i have need of Z

R=896324077e81aa06ee4b61d2f7d769a7726fd1b0d468c7599038e9c279954b2a S=d99dd8fc7d32cdf025cba3bd80ed51a6dbf860da29eb506c40016f22a19efc42

what is Z??

what is formula or python scrypt for calculate z?

when i use RawTX_RSZ.py
i have this error

File "RawTX_RSZ.py", line 8, in <module>

this is tx

i can't take z

is there any solution?
18  Bitcoin / Development & Technical Discussion / Re: Help Get RZS value error ....OFFER BOUNTY IF RECOVER BTC on: October 07, 2022, 08:17:33 AM
NotATether can you check private message please?
19  Bitcoin / Development & Technical Discussion / Re: Help Get RZS value error ....OFFER BOUNTY IF RECOVER BTC on: October 06, 2022, 09:19:13 PM
thanks NotATether for your support
what do you mean just double-SHA256 the rawtx like any other transaction??
is there a python scrypt for to do calculation??
because
https://github.com/iceland2k14/rsz
and
Bitcoin-Key-Compression-Tool  RawTX_RSZ.py
don't work for my transaction

Pkscript
OP_HASH  ..........

OP_EQUAL


Sigscript
OP_0

3045......
3045......
3046.....
5321....
no Witness

can you please create 1 python scrypt for to do calculation of z ??

i riceve this error
assert(len(pub) == pubLen*2)

20  Bitcoin / Development & Technical Discussion / Re: Help Get RZS value error on: October 06, 2022, 03:17:58 PM
Then the z value is just a double SHA256 of the transaction bytes after performing a little cosmetic surgery on it to add some bytes and substitute in a Ripemd160 hash

https://github.com/stateactor/Bitcoin-Key-Compression-Tool/blob/master/txnUtils.py#L31-L54

i have this error

assert(len(pub) == pubLen*2)                                                                                                                                        
AssertionError              

it's a btc transation not eth      

i have btc transaction
i have btc address
i have pubblic key
i have R
i have S
i must recover Z
