How can you recover a blockchain.com or blockchain.info password?
Recovering a password for a blockchain.info JSON file can be a daunting task, but there are several methods that can be used to recover the password. One popular tool for this purpose is btcrecover, which is a free and open-source password recovery tool. This tool uses a combination of different techniques, such as brute-force attacks, dictionary attacks, and wordlist attacks, to crack the password for the JSON file.
To begin the password recovery process, you will need to download the latest version of btcrecover from the official website. Once the tool is downloaded, you will need to extract the contents of the ZIP file to a folder on your computer. After this, you can run the btcrecover executable file to start the tool.
The next step is to import the blockchain.info JSON file into btcrecover. To do this, click on the “Import” button and select the JSON file from your computer. Once the file is imported, you will need to select the password recovery mode. Btcrecover offers several different modes, including dictionary attack, brute-force attack, and hybrid attack. The dictionary attack mode uses a pre-defined list of words to try and guess the password, while the brute-force attack mode tries every possible combination of characters until the correct password is found. The hybrid attack mode combines the two methods to increase the chances of success.
After selecting the password recovery mode, you can begin the recovery process. Depending on the complexity of the password, this process can take anywhere from a few minutes to several hours or even days. Btcrecover also allows you to pause and resume the recovery process, which can be useful if you need to shut down your computer or take a break.
Another tool that can be used to recover a password for a blockchain.info JSON file is hashcat. This tool is also free and open-source and is designed to crack passwords using a combination of brute-force, dictionary, and hybrid attacks. Hashcat supports a wide range of algorithms and file formats, including the SHA-256 algorithm used by blockchain.info.
To use hashcat, you will need to download the latest version from the official website and extract the contents of the ZIP file to a folder on your computer. Once the tool is extracted, you can run the hashcat executable file to start the tool. The next step is to create a hash file from the blockchain.info JSON file using the following command:
hashcat -m 1400 -a 0 -o output.txt --outfile-format=2 hash.txt rockyou.txt
This command tells hashcat to use the SHA-256 algorithm (-m 1400) and to perform a brute-force attack (-a 0) using the rockyou.txt wordlist to crack the password. The output is saved to the output.txt file in hashcat format.
Recovering a password for a blockchain.info JSON file can be a time-consuming process, but with the right tools and techniques, it is possible to recover the password and gain access to your funds. It is important to remember to use strong passwords and to keep your wallet files and passwords secure to prevent unauthorized access. If you are unsure about how to recover your password or need assistance, it is recommended to seek the help of a professional wallet recovery service.
