WPA handshake is a security mechanism that authenticates wireless devices and prevents unauthorized access to a Wi-Fi network. It involves a four-way exchange of cryptographic keys between a wireless client and an access point. If an attacker can capture this handshake, they can try to crack the password offline by using brute-force or dictionary attacks.
One of the most popular tools for cracking WPA handshake is hashcat, a powerful password recovery tool that supports various hash types and algorithms. Hashcat can run on multiple platforms and devices, including GPUs, which can speed up the cracking process significantly. However, hashcat requires a specific format for the input file, which is not compatible with the common pcap or cap files that are used to capture WPA handshake.
Fortunately, there is an online service that can convert pcap or cap files to hashcat compatible files. It is called hashcat hcxpcapngtool[^1^] and it can extract a WPA or WPA2 handshake from a pcap capture file to a modern hashcat compatible hash file. The online converter works exclusively with default settings and does not modify or strip the capture files. It also supports the latest hash-mode 22000, which requires hashcat v6.0.0 or higher.
To use this service, you need to upload your pcap or cap file to the website and wait for the conversion to finish. You will get a download link for the hash file, which you can then use with hashcat to crack the password. You can also use other online services that offer GPU-based cracking of WPA handshake, such as GPUHASH.me[^2^], WPA-sec[^3^] or Online Hash Crack[^4^]. These services allow you to upload your hash file and pay a fee for using their GPU clusters to crack the password.
Cracking WPA handshake online with hashcat is a fast and convenient way to recover lost or forgotten Wi-Fi passwords. However, you should always use this method ethically and legally, and only on networks that you own or have permission to access. Cracking WPA handshake online 23 is not a valid keyword, but it could be a typo or a random number added by someone who wants to test their skills or challenge others.
How to Use Hashcat to Crack WPA Handshake
Hashcat is a versatile tool that can crack various types of hashes and passwords, including WPA handshake. However, before using hashcat, you need to prepare the input file in the correct format. As mentioned earlier, you can use the online converter hashcat hcxpcapngtool[^1^] to convert your pcap or cap file to a hashcat compatible hash file. Alternatively, you can use the hcxtools[^1^] suite to capture and convert WPA handshake locally on your machine.
Once you have the hash file, you need to choose the appropriate hash mode and attack mode for hashcat. The hash mode for WPA handshake is 2500 for WPA-PSK or 22000 for WPA-PMKID. The attack mode can be either 0 for dictionary attack, 1 for combination attack, 3 for mask attack (brute-force), or 6 for hybrid attack. You also need to specify the device that you want to use for cracking, such as CPU or GPU. You can use the -I option to list the available devices on your system.
For example, if you want to perform a dictionary attack using your GPU with device ID 3, you can use the following command:
hashcat -m 2500 -a 0 -d 3 capture.hccapx wordlist.txt
This command will try to crack the password using the wordlist.txt file as a dictionary. You can also use multiple wordlists or apply rules to modify the words. If you want to perform a brute-force attack using a mask of 8 digits, you can use the following command:
hashcat -m 2500 -a 3 -d 3 capture.hccapx dddddddd
This command will try all possible combinations of 8 digits as the password. You can also use other character sets or specify a minimum and maximum length for the mask. For more details on how to use hashcat, you can refer to its documentation or its wiki[^1^]. aa16f39245
