How to crack bitcoin Wallet

1. It depends on your ability to crack people. People with high ability may take only a few minutes.

2. I forgot my private key, but I can't solve it

3. First of all, let's talk about the background. The basic principle of bitcoin "account" is key public key address. You can roughly understand it as "key box box number". Now is to start from the box number or box to crack the key
there are basically two kinds of attacks, one is dictionary attack, the other is brute force attack
dictionary attack is to use common passwords and their simple variants as keys one by one. As long as your pass phrase is not hard enough, the possibility of successful attack is very high. So if you want to use this, you need to popularize the knowledge of cryptography first, and don't think it's very safe to add a long password
if you don't use the wallet generated by pass phrase, you can only crack it violently, which is equivalent to enumerating all the possible keys. At present, this is impossible, even if the electronic computer is becoming more and more powerful. However, quantum computer can do it theoretically, but don't worry too much. If such a powerful quantum computer comes out, it will not only endanger bitcoin
at the same time, bitcoin has a second layer of protection: if an address only accepts bitcoin but does not output it, its public key is confidential, that is to say, no one else can see the box, only the box number. At present, the process of decing the box from the box number can't even be done by quantum computer. In other words, if there is a quantum computer, bitcoin has a last line of Defense: it's temporarily safe to transfer your money to a new address
finally, some time ago, the wallet generated by the Android client was attacked because of a bug in the underlying random number generator. In fact, this function is not random securerandom, which Google quickly admitted and fixed. It's hard to say whether this kind of thing will happen again, but I don't think we need to worry too much.

4. Common measures to deal with the loss of private key and password:
1. Delete the wallet by mistake
this is the same operation as I do. What should I do in case of this kind of thing? In fact, as long as you remember the private key, download a wallet again, import the private key and reset the password of the wallet
2. The mobile phone is missing or broken
if your mobile phone is stolen or broken, as long as the private key or mnemonic word is still there, you can download a wallet again, import the private key (or mnemonic word) and recreate the wallet
3. The private key is forgotten, but the mnemonic (or JSON file) is still there
if your private key is lost, but the mnemonic (or JSON file) is still there, don't worry, mnemonic can help you retrieve the private key,
4. The private key is forgotten
the wallet hasn't been deleted. If your private key is forgotten, but the wallet is still on your mobile phone, it's very easy to do, You just log in with your password, enter your wallet, and back up your private key
5. The private key, password and mnemonic words have been lost
sorry, no one can help you
6. Forgotten password or wrong input
this is the same as some other apps that we usually log in. If we forget password or input error several times, click forget password to retrieve it. Back to the decentralized wallet, we need to use the private key or mnemonic words to import the wallet to reset the password
7. Forget the mnemonic words
import the wallet with the private key and back it up again
8. Keystore forgotten
if your wallet is not deleted, this is the same way as if your private key is forgotten but your wallet is not deleted, that is, log in with your wallet password and make a new backup; But if your wallet is deleted, that is, it is unloaded, you need to import the wallet with mnemonic words or private key to backup the keystore again!

5. If you use brute force to crack the wallet, you must remember the password phrases you used, for example, I must have used ABC, I may have used 321, and so on. If the wallet address is not yours, you can't crack it even if you use up the energy of the sun. Regular company can come to sign an agreement to crack the service.

6. The landlord can use the wallet password retrieval tool to help you retrieve your password. The tool is available for download at xingfeng.org. Of course, if the wallet is not you, it is difficult to crack, because the password strength of the wallet is very high. Although the tool can be used as a password cracking tool for bitcoin wallet, the efficiency of brute force cracking is not enough..

7. Continue to wait for confirmation, but bitcoin can't reverse trade, it can only do so. Bitcoin receives payments almost instantaneously. However, there is an average delay of 10 minutes before the network starts adding your transaction to a block to confirm the transaction and that you can use the received bitcoin. Confirmation means that there is a consensus on the Internet that the bitcoin you receive is not used to pay others, so it is recognized as your property. Once your transaction is included in one block, all subsequent blocks will include it, which will greatly consolidate this consensus and rece the risk of transaction cancellation. Each user can determine the time when the transaction is confirmed, but generally speaking, receiving six confirmations is as safe as waiting six months after a credit card transaction.

8. Do you know how many digits the password is, or do you have keywords? I can give you a try

9. Try Tencent computer housekeeper killing, physical examination speed is very fast, Trojan horse killing ability is not weak at all, for virus Trojan horse, high-risk vulnerabilities, system abnormalities will not be a mistake. Although the interface is smaller, but the function is not discounted, it is still very powerful, and the killing rate of Trojan samples in the evaluation process is 100%
the physical examination and repair of the pioneer version of computer housekeeper are very fast. It can quickly remove Trojans and fix loopholes without a long wait and has no impact on the running speed of the computer.
