Hi.
is there a python script somebody know,
that can genearate HEX numbers in a given range and output it in a txt file ?

What do you mean exactly?
(a) Random hex numbers within a range, (b) all hex numbers within a range, (c) convert a list of decimal numbers to hex numbers or (d) something else entirely?
Also, what are you trying to do?

Since you're not being specific, i made something very simple start = 0x0 end = 0xF path = './file.txt'
with open(path, 'w+') as f: for x in range(start,end+1): f.write(hex(x) + '\n')
The output should look like this 0x0 0x1 0x2 0x3 0x4 0x5 0x6 0x7 0x8 0x9 0xa 0xb 0xc 0xd 0xe 0xf
But as @HeRetiK said, what do you want to accomplish? It's possible you fell to XY problem.

I'm going to assume that he's trying to generate random hex private keys (because otherwise what does this have to do with bitcoin or cryptography?), so the first thing I'd look for is a secure random number generator, so nothing that random exports. secrets is a much better module for this purpose and it has a function called randbits(n) that generates an n-bit random number. In this case, 256 bits are needed, and the result can easily be converted to hex using the hex() function. Full code is just from secrets import randbits hex(randbits(256))
Plain old insecure random numbers can always be generated using hex(random.randrange(start, end))And of course we can always iterate through a range using for a in hex(range(start, end)):
Hi, you can use secrets library.. "pip install secrets"
You don't need to install it from pip (it isn't there anyway) because it's bundled with Python since 3.6.

Hi, you can use secrets library.. "pip install secrets" import secrets
for n in range(100): # replace 100 by your number of time bits = secrets.randbits(256) # replace 256 by your choosen range (here this is the number of bits) with open('result.txt', 'a') as file: file.write("\n" + hex(bits)[2:])
et voila ! edit: it is for random génération, don't know if you want a linear génération ? in this case ETFbitcoin example is the good one ^^

I would like to have a Script like this https://github.com/saracen/bitcoin-all-key-generatorin python, because thats what i have installed 2.7 and 3.xx. Where i can set the starting point for example start with 0000000000000000000000000000000000000000000000000000251462abc584 and output to a txt file. @NotATether, you told me in pm the PK, with missing letters, is in a range of xxx and xxxxx so maybe i can search it this way.

You want a random 256-bit number like this: import random random.getrandbits(256)
this will output a 256-bit number, just like any bitcoin private key. I ran this here and it returned: 92190443112138794064351826137983695759100025828546020995296739378362186540927 To create a file you can use ETFBitcoin solution, like this: import random
path = './file.txt'
with open(path, 'w+') as f: f.write(str(random.getrandbits(256)))
https://en.bitcoin.it/wiki/Private_key#:~:text=In%20Bitcoin%2C%20a%20private%20key,range%200%2D9%20or%20A%2DF. In Bitcoin, a private key is a 256-bit number, which can be represented one of several ways. Here is a private key in hexadecimal - 256 bits in hexadecimal is 32 bytes, or 64 characters in the range 0-9 or A-F.

It look all great, and thx for all that wanna help.
Now how can i start with a from me given HEX number for example 0000000000000000000000000000000000000000000000000000251462abc584, and lets say, generate linear the next 10k HEX numbers or 20k.

But it is possible, to write all the hex, in the txt file, every in one line ... so that on 10k it generate 10k lines linear to the start HEX number ?!

I was not able to reproduce this "bug" here. But it is possible, to write all the hex, in the txt file, every in one line ... so that on 10k it generate 10k lines linear to the start HEX number ?!
You don't want to generate a random number. You want just to count in hex? That's even easier: path = './file.txt' start = int('0000000000000000000000000000000000000000000000000000251462abc584',16) stop = start + 10000
with open(path, 'w+') as f: for i in range(10000): f.write(hex(start+i).zfill(64).replace("x","0")+'\n') I made a small change in the code, added .replace("x","0") so you do not see the x again, looks more like a bitcoin private key.
Looks like you are trying to find private key with balance... This won't work for that. This is why:

base on post history of the starter i believe he is trying to recover his own private key that is damaged and is missing a part of it. that is probably why the range looks like this. although if starter was more clear about what he is trying to do he would also get better help.

There is a FOMO brewing...

I know, Bitcoin is the perpetuum mobile, of the cryptohack. But ... now comes the BUT, since i search the lost letters from my PK ( see this post https://bitcointalk.org/index.php?topic=5331951.0 ), i read and read, try to understand and try to learn. Maybe because i am a older generation ( C64 ... Amiga 500 ), the CONTRA REGULE thinking ( against normal rules ), is breaking through. Why all brute force tryings go one way. Nobody thinks CONTRA REGULE, but this is another post, what i will open soon. My biggest problem is that i cant write a script Big thanks for help, solving this problem here.

Yes but you see, it is more efficient to use the WifSolver program by @PawGo for problems like this, because something you write by hand may not be fully tested and not find private keys properly. Looks like you are trying to find private key with balance... This won't work for that. This is why:
base on post history of the starter i believe he is trying to recover his own private key that is damaged and is missing a part of it. that is probably why the range looks like this. although if starter was more clear about what he is trying to do he would also get better help. I do have the fragment of the PK for which he's trying to recover the other part. The range search, which has already been running for a day, should take a few more days to finish on my hardware. It's 11 chars missing including checksum.
11 characters at the end? Should take seconds, not hours or days.
It will take seconds on a GPU. But there are no GPU-bound programs that take a WIF and try to complete it (Bitcrack completely misses the key in the range), so I'm stuck with a cpu-bound solver running on 48 cores.

A few points that folks overlooked in this thread: 1- Iterating from start to end requires an addition, i.e. 256 bit addition. From the programmer's perspective Python handles 256 bits integers trivially but python 2.5+ requires such variable to be defined as long explicitly, and it is good to know that we are not dealing with a one-cycle operation. 2- It looks that once the production of the output file is finished the journey is just started as OP wants to read this file and produce the corresponding public key for each row, comparing it with his target, so we need multiplication and modulo operations, it raises again performance issues. It is why we should use cryptographically optimized libraries wherever possible. 3-I think, generating a file firstly then feeding it to another python script as input for some computations is not the smartest plan for this use case, especially when we are talking Pythonic Instead I'd do something like this: //This is coded for python 2.5+
from pybitcoin import BitcoinPrivateKey
// check the repository here // https://github.com/blockstack/pybitcoin
start = long(someValueHex) stop = long( biggerValueHex) target = long(targetPubKeyHex) def generate (s,e): while s <= e: yield s //it is a generator rather than an ordinary function s += 1 yield 0
def searchForTarget: candid = generate(start, stop) while true: pk = next(candid) if pk == 0: print("Exhausted the search space, sorry, no good news :( " ) break private_key = BitcoinPrivateKey(pk) public_key = privatekey.publickey() if public_key == target: hex_private_key = private_key.toHex(); print("FOUND! :) /n %s" , %hex_private_key) break

If that is what OP was really wanting, versus priv keys he can feed to some program to do the conversion, then I would not use pybitcoin; using it is a lot slower than other ways. When I ran tests, generating random private keys and converting them all the way down to BTC address, pybitcoin was 2.5 times slower on python 2.7

11 characters at the end? Should take seconds, not hours or days.
It depends on whether the key is compressed or uncompressed. For a compressed key you have to check about 22 million while for an uncompressed key the number is 5.8 billion. // Numbers are approximates, values usually are ±1 // Uncompressed ; Compressed // 1-5 -> 1 ; 1 // 6 -> 9 ; 1 // 7 -> 514 ; 3 // 8 -> 29,817 ; 117 // 9 -> 1,729,387 ; 6,756 // 10 -> 100,304,420 ; 391,815 // 11 -> 5,817,656,406 ; 22,725,222 // 12 -> ; 1,318,062,780
For the first case it takes about 2 minutes to check all the keys using FinderOuter
