Install wpa_supplicantapt-getinstallwpasupplicant2, create/etc/wpa_supplicant.conf contains the following content: network = {ssid = "your wireless network ssid" psk = "Your wpa password" key_mgmt You must have completed wireless

WEP is a technology that encrypts group information in the "RC4" way between the Access Point and the client. It is easy to study and learn passwords. The encryption key used by WEP includes a 40-bit (or 104-bit) Universal key pre-determined by both sending and receiving sides, and a 24-bit, known as an IV key, that the sender determines for each group's information. However, in order to notify the communication object of the IV key, the IV key is directly embedded into the group information and

Briefly describe some of the key words in WPA/WPA2 's 4-time handshake:WPA/WPA2 uses a 4-time handshake to generate the required key. The four-time handshake generates PTK (pairwise Transient key) from the PMK (pairwise Master key) through a series of interactions. The PMK is from MSK (Master Session Key), which is the first 256 bits of the MSK, 32 bytes.PTK contains 3 parts, KCK (Key confirmation key), KEK (key encryption key), TK (temporal key).The

We all know that it is dangerous to make transactions in a shared wireless network, such as online banking transactions. Therefore, WPA can be used to encrypt the internet. the following is a summary of how to configure WPA for wireless NICs in Ubuntu (orDebian. first, update the resource list. The command is as follows: sudoapt-getsudoapt-getinstallwpasupplicantsudoapt-getinstallnetwork-manag We all know

Wi-Fi networks allow us to access the Internet conveniently, but at the same time, we do not want the hacker next door to visit our network, so we naturally need to add a password for WiFi, right? The good news is that you may have read another article about "How to easily crack the WEP password", so you have used a more robust WPA security protocol. But the bad news is that there is a new Free and Open Source Tool, Reaver, which has discovered a vuln

We have introduced three encryption methods: WEP encryption for conventional wireless security measures, restriction of MAC addresses for wireless NICs to make the network more secure, and prohibition of wireless SSID broadcast to protect network security, the WPA-PSK wireless encryption introduced in this article is a special encryption method, because some NICs do not support this encryption method. 1. Configure

Although the title is 5 seconds to crack WPA-WPA2 WiFi password, but in fact this is the kind of router for foreign countries, our big celestial routers more and more powerful. Some routers have anti-pin, even some routers do not have pin,wps and so on. But there are some that should be useful. Here's how to say:Tool: I downloaded the dumpper v.80.8 +jumpstart+winpcap in https://sourceforge.net/projects/dumpper/files/this URL, but this is not good to

I caught a handshake packet, and spent a lot of effort to run the password out of the dictionary, but I couldn't connect to the wireless router at the end ...... Come on, and create an experiment together! Step 1: Set up a wireless router for the experiment, as shown in Figure 1: We can see from 1:1. The security mode is WPA.2: The password is 11111111" Step 2: Modify the dictionary file to include the correct password "11111111" and the wrong

WPA/RSN uses 4-way handshake to generate the required key. Function The four handshakes generate a PTK (pairwise transient key) from the PMK (pairwise master key) through a series of interactions ). The PMK is derived from the master session key, which is the first 256 bits and 32 bytes. The main purpose of this article is to talk about PTK, So we temporarily ignore PMK and MSK. PTK content PTK consists of three parts: kck (key confirmation key), KEK
