you mean you be hacked
I was interested if it is possible with private keys and do the thing called "brute force", yes that is what I am talking about, thank you for your explanation.
When people ask such questions - from what chance is that somebody will generate the same wallet (private key) as yours to how hard is to brute force a private key - I like to point them to this image. It's already old, but it's well written.
The image tells how hard is to just count all the possible addresses. After seeing it, you'll understand that brute forcing it it's clearly impossible.
this is very terrible, i lost my last wallet.dat while reinstall my Windows. have anymethod to restore my wallet?
It is vital to back up your wallet.dat (or the seed, if that applies). If you did not back up your wallet, then there is no method to restore it.
I forgot my password to my blockchain wallet, now I can't access it
Blockchain.info has several recovery methods if you took the time to set them up. I believe you can recover your wallet with either the seed (a list of words) or the account mnemonic (a longer list of words). The site has details and instructions.
Once you lose your password, probably you are lost. However, some guys on the services forum offer password recovery service. Search for it.
maybe he has forgotten his password, there's no way to recover your password, which wallet do you use? and what do you save, whether bitcoin, eth, ltc, etc. if you mean lost your password, you can reset it by forgot password, but if you use hardware wallet or another wallet that use seeds or private key, there's no way out except you back it up before your password being lost.

I had to read the entire post to figure out if you were talking about a bitcoin lost wallet (.dat) or a bitcoin lost password…
I don't know if there are other options than restoring your system or finding a data recovery tool for lost wallet .dat.
All I know is that there is a solution for bitcoin or litecoin users who lost their password. Actually I have recovered my litecoin password using recoinvery. It seems that this freeware also works on bitcoin and few other coins but I only can confirm that it worked great to get my ltc wallet password back
Hope that this will help you

How safe is it to use?

just remember/write down the private key and password. DONE.

I think there are boundary conditions for the recovery: either you had taken a very weak password in the first place or you have still some idea about the password. I think there will be no way to recoup your passphrase if it is well chosen.

wumpus lool that is what I am talking about, I was interested if it is possible with private keys and do the thing called "brute force", yes that is what I am talking about, thank you for your explanation.
If you created your wallet with a passphrase i think there is someone that offers recovery wallet services. I don't remember the site though.
The technique is this:
1. Generate a random 256-bit number between 0x1 and 0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4141. (a private key).
2. Determine the bitcoin address for the generated private key.
3. If the generated bitcoin address matches, you have the private key and you are done. If not go back to step 1.
This is called "brute force". There is no other technique.
As for step 2, the details are here:1. Generate a random 256-bit number between 0x1 and 0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4141. (a private key).
2. Determine the bitcoin address for the generated private key.
3. If the generated bitcoin address matches, you have the private key and you are done. If not go back to step 1.
This is called "brute force". There is no other technique.

Edit: and with "vanity address generators" you can bruteforce addresses efficiently, though not efficient enough to get the private key belonging to a certain address within the age of the universe.
Yes, I agree with you it may be lost, but I am interested in the technic of recovering it, what tools should i use to try until it be recovered? Do you understand what I am saying?
If you only have the public address or public key, there is no real way (other than brute force) for you to recover the private key.
If someone is able to do that for you, he could have taken everyone's btc as well.

Thanks for your response Nolo, yes i was talking about my public key a.k.a bitcoin address, thank you for explaination.
In that case, your bitcoin is probably forever lost.
