BitCrack - A tool for brute-forcing private keys

[italiandigger]

You need to know that most services not allow to mining and similar behavior like keyhunt, they will block you account immediately over night.
both UpCloud & wholesaleinternet I use it for keyhunt without any problem

Has been difficult to configure upcloud or wholesaleinternet to install and run keyhunt?
Is it like i do it on my linux laptop or is it something more difficult?
(i used for a while an ubuntu laptop some years ago even if i don't remember too much)

Don't you fear that the server admin can read the privkey if you find it?

The install done by host provider. you will get access via SSH terminal. There are no desktop or graphic interface, you have just terminal (text interface)
So you need to be OK with using terminal for all things.(just few command to learn and you ready to go)
*They are some host that provide Windows desktop but its so expensive compare to Linux.

You will be the only admin in that host, the connection and access will require your SSH-RSA.

SSH-RSA is secret and public keys. The provider will ask you to give them your public key to encrypt your host and you will be the only one can access it via your secret key.

It's very interesting, but i have a doubt:

The cheapest solution on https://www.wholesaleinternet.net/dedicated/ costs 9$/month: Intel Core2Duo 1,6Ghz 1 processor 2 cores 2 threads RAM 4 Gb DDR2 250GB SATA

My laptop has an Intel i7 4500U 1,8-3,0 Ghz 2 cores 4 threads RAM 8 Gb DDR3 250GB SSD.

My laptop seems more powerful or am I missing something?

My laptop is 65W so with italian high cost (0,00032 W/h) i could pay 15$/month (9$/month seems better).

You should go with Xeon processor if you want to have chance. less than that is absolute zero(bitcoin range is tooooooooooo...etc big)

You miss about cooling because you laptop will run 100% all time which will cost you much then that.
And also don't miss the noisiness

Noisiness for sure during the night .
It does not seem to overheat much with keyhunt, not using the gpu in my opinion it does not consume more than 2 times the 15W declared by Intel for the middle cpu usage plus something for the rest of the hardware maybe it does not reach 30-40W (65W is the maximum of the transformer).

How many privkeys can you examine monthly with your rented Xeon? How many keys/s does it reach?

Prices for 36 cores/72 threads is 100$/month.  
How many privkeys do you think can i examine in one month with a Dual Xeon E5-2696v3 128 GB 2x2 TB SSD?

Why 9 Xeon cpu if a single GPU 3070 can reach 1337 MKey/s?

Why 9 Xeon cpu if a single GPU 3070 can reach 1337 MKey/s?

Yeah I learn my lesson so all my search now is on GPU.
But you keep talk about going with CPU so I give the advice to go with top one to reduce your lesson time and cost to half  

In vast.ai the RTX 3070 is 1200 MKey for 0.069h, For month 0.069x24x30=49.68$ half of one dual Xeon server price.

[7isce]

The public key usually only used as SSH authentication though, rather than encrypt the host itself.

I agree with that because the data must be available any time uncle sam request it

It means that the server owner/employees can read the privkey too.. maybe faster than you (you cannot check it h24)

When accessing the server you can disable any account created by hoster and you can change root password...etc
So the only thing owner/employees can read is the hard disk/SSD without access system.
They can hack you system but you will be know that because you can't access it anymore.

Do you try mainly random or secuential with keyspace small portions?

If the operator wants to hack into your own box then why are you renting from them in the first place?

Private key searching is sensitive business, how can you be sure that there aren't a bunch of oscilloscopes hooked up to your server to measure secp256k1 timing frequency, if you have to resort to locking the operator out?

[KudilCumil]

hallo,..
need an explanation about multiple addresses.
how is it work?
is it :
1. search key for the first address of the list >> found >> move to 2nd address of the list?
2. search key randomly and match to any addresses on the list?
thanks

Hi 7isce, about bsgs I tested it with a short and fast keyspace (post #1601) but  it cannot find the puzzle 64 pubkey..
Have you done other tests to verify that the bsgs mode really works fine?

[italiandigger]

I was thinking to a cheap Xeon low energy workstation:

CPU
2x Intel Xeon E5-2630L v3 - 1.80GHz / Eight Core / QPi 8 / Cache 20MB / TDP 55W P/N: SR209

Heatsink
2x heatsink

Geheugen
8GB 2Rx8 PC4-2133P Hynix P/N: HMA41GR7MFR8N-TF

HDD
300GB 15K SAS 2.5" DP, 6G, DELL P/N: 0H8DVC

FlexRom NIC Adapter
HP FlexRom 533FLB P/N: 647586-B21

PSU
HP 500W HPE 500W Power Supply Platinum, HSTNS-PD40 P/N: 723594-001, 723595-101, 754377-001

This workstation could be better than my laptop with i7 4500U 1,80 - 2,40 Ghz. Could I reach a better performance (Keys/s) with keyhunt (cpu mode)?
Xeon E5-2630L v3 has 8 cores and 16 threads.
My i7 only 2 cores 4 threads.

Try this clBitcrack -o out.txt --keyspace f7051f27a09112d4:f7051f37b09112d4 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN

I did the suggested test with another software: keyhunt (https://github.com/secp8x32/keyhunt/tree/master/x64/Release)
The suggested test keyrange is 68.987.912.192 keys (it is useless to test it with clbitcrack because with 260000+ keys it skips the key found)

Keyhunt fullfills the target in 3.30 hours on my old laptop with geforce 820M!!!

I haven't enough experience to setup correctly the software, I don't know for example if and how i can allocate memory to reduce the processing time.
Keyhunt continues to elaborate the base key until the end of keyspace, i quitted it once i've seen that the key has been found.
Brainless you are right, it takes a lot of time to check 37.181.645.904.000 keys (116.160 times more than 268.436.000 keys with my old laptop if keyhunt cannot be set better)  
Clbitcrack is totally useless because it create the false illusion that the key can be found very quickly with any keyrange, but it's not true (it works with maximum 260000 keys only).
If you know how to setup better keyhunt, please let me know.
Did you tested keyhunt with better graphic cards like Gtx1080ti or Rtx3070? How many key/s do you reach?

hallo,..
needs explanation what is the next step after found private key?
cant open wallet address using above private key found,.. is there anything else to be done after found private key,..
thanks

If the wallet (like the puzzle 64) is empty you cannot sign new transactions. Zero bitcoin means zero transactions available.  
Here you can find an archive of private keys, all empty wallets : https://privatekeys.pw/keys/bitcoin/3
If you are lucky and you find a privkey with bitcoins inside you can use a wallet like Exodus (there are tutorials online how to importing a paper wallet).

i tried to use electrum on that found private key, but electrum doesn't recognise the format of that private key.
how we use found private key? is there any other process to change format of the private key so it can be use on electrum or any wallet?

@KudilCumil
Raw data is what we call hex or binary.
maxim 256 bit supported to be as bitcoin private key.
Most wallets support WIF keys or SEED etc
For you such case you need to convert answer from hex private key to compressed WIF private key to get compressed address
For example puzzle 64 key is
