1  Bitcoin / Development & Technical Discussion / Re: VanitySearch (Yet another address prefix finder) on: Today at 12:39:25 PM
What meaning -m option
yes, my input file have a lot of prefix search

It's only used in GPU search.

It dictates the size of the array that stores the prefixes on GPU memory. It is not possible to search for more prefixes than this simultaneously, because you cannot write past the end of allocated memory or you will get a Segmentation Fault! Instead of hard failing like that, VanitySearch drops some prefixes to stay within the size limit.

Kangaroo also has this kind of concept, only with DPsize.

Thank you

I will try decrease input file with not have much prefix search may be help to faster and better n small GPU

How I can fix it?

You're overfilling VanitySearch's GPU buffers with starting keys, so it's dropping them after the maximum number it can fit in. You need to increase maxFound to something bigger than 65536 using the -m option.

Thank you

I test add  -m 1000000   then no message warning

4  Bitcoin / Development & Technical Discussion / Re: Collection of 18.509 found and used Brainwallets on: April 11, 2021, 09:44:39 AM
I agree Brainwallets are much worse

Brainwallets use keywords + sha256

I see mini private key is using by 30 character and hash with sha256 still safety
 but mini privatekey have format

However random text and number or text only or number only 256 character (or 512 character ) hash with sha256  (64 character), I think it is safety not easy to butte force with random 256 key easy (just 64 bit key
but some duplicate some private key will duplicate with number 265 bit (77 character) convert to HEX  (64 character)

private key require HEX  in 64 character right
so, What method to can generate it to safety?
5  Bitcoin / Development & Technical Discussion / Re: VanitySearch (Yet another address prefix finder) on: April 11, 2021, 09:22:46 AM

I would like to try modify VanitySearch output when using option -o output.txt
modify to display at one with with comma (make it like csv file)

Where can I try to change it What file and what line or what position code?
6  Bitcoin / Development & Technical Discussion / Re: Collection of 18.509 found and used Brainwallets on: April 10, 2021, 11:18:36 AM


Brainwallets is keyword or message + sha256 = private key , right?

What if using  random 256 number (character) and + sha256 = private key it still safety?
or   random text 256 character and + sha256 = private key  still safety?

Brainwallets count only word and language human read only right?

What about this article?

https://sefiks.com/2018/02/27/counting-points-on-elliptic-curves-over-finite-field/

What function for Baby Step Giant Step works on article?
8  Bitcoin / Bitcoin Technical Support / Re: pywallet install help on: April 09, 2021, 04:55:53 AM
this file have problem when copy/rename from bitcoin open and not close (between use)
inside file will have all data still in there  but some locked file when using or head data have problem
I think if bitcoin program error , hang, freeze, not respond, make file have problem to read program not close  normal
Wait... so your copied/renamed the wallet file while Bitcoin Core was running? Huh If so, that is highly likely to result in wallet file corruption... Undecided

As far as I'm aware, there is no "one size fits all" method to be able to fix it... As it depends on what exactly was being written to the wallet file when it was renamed/copied etc.

If it has been corrupted so badly that PyWallet is unable to open it using --dumpwallet, then it could prove quite difficult to recover. You might have to try --recover and see if it is able to extract the keys and rebuild a new copy of the wallet.

Otherwise, you can try the bitcoin-wallet tool and see if the salvage command can fix it...

yes, I just testing to know
Why many people have problem with wallet.dat a lot many thing corrupt?
look like a big problem with wallet.dat corrupt
some lost bitcoin permanence
some very hard to fix it
and other way if happen with me how can I solve this problem may be it possible happen with me and inside still have my real bitcoin

just try to test fix it without open bitcoin program again to fixt it

I do force talk close bitcoin program it is same result can not use that file

I think file not damage at all data still inside but something make it can not read it
I am not programmer try to use only tools

Thank you very much for Pydroid 3 - IDE for Python 3
very good app

I know brainwallet is not safety
but we can modify and change to random 256bit number right
10  Bitcoin / Development & Technical Discussion / Re: Converting RIPEMD160 to address on: April 08, 2021, 02:23:11 PM

if want to reverse address to RIPEMD160 for recheck is correct (or use convert address to RIPEMD160)

Do you have simple code?

The base58 library provides a base58decode_check function that decodes a byte-encoded base58 string back into a byte array. Note that you must convert the base58 string to bytes first before you can pass it as an argument, and because you not only get RIPEMD160 bytes but also the checksum back, you need to strip the checksum too.

Code:
import base58

addr = "insert base58 address here"

bytesaddr = bytes(addr, "utf-8")
r160check = base58.base58decode_check(bytesaddr).decode('utf-8');

r160 = r160check[2:] # If you put a "00" at the beginning of the string, so remove it
print(r160)

Thank you NotATether

This is my python script for searching puzzle 64 it's generating an .bat file with  random keyspace between puzzle64 keyrange. I'm using vanity + bitcrack
 

try this
first time I using python and batch file too

now I change to use only python and run cuBitcrack.exe by call program from python direcly)

try using subprocess fuction

import subprocess
p=subprocess.Popen(command,shell=False)

just use one python file
12  Bitcoin / Bitcoin Discussion / Re: Baby Step Giant Step Combined Efforts to Find 1.2 Bitcoin on: April 08, 2021, 01:25:25 PM

I want to know How Baby Step Giant Step work and How Baby Step Giant Step calculate

https://github.com/JeanLucPons/BSGS

Did BSGS calculate private key by jump with Baby Step Giant Step algorithm?
I mean number 2**119 to 2**120
or
Did BSGS with point x (ECC) like kangaroo?

 
13  Bitcoin / Bitcoin Discussion / Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it on: April 08, 2021, 08:48:55 AM
I found hack page or may be webmaster hide page (may be scam)

this page random bitcoin address generator

www.50pansa.info/random.html

so, have any brute force address on java script

I not sure this script is clean or not, just fine to safety file on github

(however it is lowly)

Can possible anybody help to modify to brute force ?
it can run on mobile easy
14  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: April 08, 2021, 06:34:57 AM
some idea

Can someone Fork BitCrack to version for puzzle #64 only

BitCrackPuzzle64.exe

some detail
Create database from firebase free version (1GB storage)
pool scanned database

split scan from 100,000,000 keys to 1 slot  (or if too much may be = 10,000,000)
so, will got 92233720369 slot
random 1 from 92233720369 slot and scan

if random slot number not have store on database then begin scan that slot
but if random slot number have store on database already, then scan new one slot

second slot will start from 9223372036854775808+100000000 = 9223372036954775808
slot number 999 will = 9223372036854775808+100000000*999 = 9223372136654775808

when scan complete slot sent request to record slot on firebase database
that mean that slot already scan

when other people scan will be check same system and skip slot not found to ther slot

options
make option -slot (number)  for can custom order to scan

if number slot have on record
give error message "slot 999 already scanned"

firebase c++
https://firebaseopensource.com/projects/firebase/quickstart-cpp/

just sn idea not serious

now we work some same thing with burn resource out  (many people do same job same keyspace but not fould
this system will be help to skip address that already scan
15  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: April 08, 2021, 06:09:21 AM

on think about puzzle #64 and other
private key may be on some where people not yet scan

calculate time scan 1 day from start and skip it may be save time
I think every start from start point will be scan same

some where not from start and middle(half)

16  Bitcoin / Bitcoin Technical Support / Re: pywallet install help on: April 08, 2021, 05:59:04 AM
are you using the latest version of PyWallet? (that has been updated recently by jackjack) or are you using the old version? Huh

Also, where is your wallet.dat actually located? The --datadir value you are using is where Python should be installed to... not where your wallet.dat is likely to be located unless you manually copied it there.

I copy wallet.dat to folder for test

Try jackjack pywallet.py got same result


python pywallet.py --dumpwallet --wallet=C:\python\27\008\wallet.dat
(22, 'Invalid argument -- C:\\python\\27\\008\\wallet.dat: unexpected file type or format')
ERROR:root:Couldn't open wallet.dat/main. Try quitting Bitcoin and running this again.


I test change wallet.dat to other one normal (this file success to dumpwallet)
result can dumpwallet success no problem (use same command)

actually file that have problem this one , when I copy back to bitcoin data folder and run bitcoin again and close program correct and try dumpwallet it is work normal

Just want to know how to fix it (not serious )
this file have problem when copy/rename from bitcoin open and not close (between use)
inside file will have all data still in there  but some locked file when using or head data have problem
I think if bitcoin program error , hang, freeze, not respond, make file have problem to read program not close  normal
17  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: April 08, 2021, 02:44:14 AM
Is there any way to generate all privat keys with compressed and uncompressed and save them to txt file with 100MB Splited size?

starting from:
000000000000000000000000000000000000000000000001A838B13505B26867
ending on:
000000000000000000000000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF






Just using python script running you can find easy

I know you want to use very fast key generate like bitcrack
not yet have someone help to modify to save to file
 
18  Bitcoin / Development & Technical Discussion / Re: Mass Private Key to Bitcoin Address Converter on: April 07, 2021, 12:56:37 PM
Can possible update code to write file output

may be good for export to file is better print out if it is massive may be 1 million or billion key it need to save to file
19  Bitcoin / Bitcoin Technical Support / Re: pywallet install help on: April 07, 2021, 04:33:45 AM

Code:
python pywallet.py --dumpwallet --datadir=C:\python\27\ >wallet.txt
ERROR:root:Couldn't open wallet.dat/main. Try quitting Bitcoin and running this again.

I test already by run bitcoin program again follow  error message tell to know
it is work fine  wallet.dat can use with pywallet.py dumpwallet success

but if I can not run bitcoin program again to fix it , How can I fix this wallet.dat
if can not open any bitcoin program to fix it or wrong version may be old version it will make wallet.dat error or not
20  Bitcoin / Bitcoin Technical Support / Re: pywallet install help on: April 07, 2021, 04:07:11 AM
test use pywallet.py how to fix
this is test , not have any bitcoin

I try test using pywallet.py dumpwallet from wallet.dat

with normal file try create new wallet thousand
python pywallet.py --dumpwallet --datadir=C:\python\27\ >wallet.txt

pywallet.py convert to file success no problem


but I try create wallet new one test and rename wallet.dat file before close
and close bitcoin program, bitcoin program error

then I use wallet.dat that copy before close bitcoin program

python pywallet.py --dumpwallet --datadir=C:\python\27\ >wallet.txt
ERROR:root:Couldn't open wallet.dat/main. Try quitting Bitcoin and running this again.

(using python 2.7)
