Your wireless Firebox supports three wireless authentication settings that use pre-shared keys: When you choose one of these methods, you configure a pre-shared key that all wireless devices must use to authenticate to the wireless access point. WPA (PSK) and WPA2 (PSK) are more secure than WEP shared key authentication. WPA (PSK) and WPA2 (PSK) Wi-Fi Protected Access methods use pre-shared keys for authentication. For more information, see About Firebox Wireless Configuration. In Fireware v12.0.2 and higher, you can enable the WPA/WPA2 vulnerability mitigation check box in the Wireless settings to mitigate KRACK WPA/WPA2 vulnerabilities in unpatched wireless clients. WatchGuard has addressed recent KRACK WPA/WPA2 vulnerabilities for Firebox wireless devices in Fireware v12.0.1 and higher. Select the most secure authentication method that is supported by your wireless network clients.
The eight available authentication methods, from least secure to most secure, are explained in this topic. Do you know of any other methods? If yes, share it with us via the feedback form below.From the Encryption (Authentication) drop-down list in the wireless access point configuration, you can select the level of the authentication method for your wireless connections. The above are some of the many ways of generating strong Pre-Shared Key in Linux. $ date | sha256sum | base64 | head -c 60 echo $ date | sha256sum | base64 | head -c 50 echo $ date | sha256sum | base64 | head -c 45 echo The date and sha256sum command can be combined to create a strong PSK as follows. Generate PSK Using Pseudorandom Number Generators 4. The -c option of the head command helps to generate the number of characters. You can also use any of the pseudorandom number generators in Linux such as /dev/random or /dev/urandom, as follows. In the following commands, 1 or 2 is the quality level and 10, 20, 40, and 70 are the character counts.
You can use its -gen-random option to generate a strong PSK and filter it through base64 encoding as shown. GPG is a command-line tool to provide digital encryption and signing services using the OpenPGP standard. Generate PSK Key Using OpenSSL Command 2. To generate a strong PSK use its rand sub-command which generates pseudo-random bytes and filter it through base64 encodings as shown. OpenSSL is a well-known and widely-used command-line tool used to invoke the various cryptography functions of OpenSSL’s crypto library from the shell. In this article, we will show you different ways to generate a strong Pre-Shared Key in Linux distributions. It is commonly used in different types of Virtual Private Network (VPN) connections, wireless networks in a type of encryption known as WPA-PSK ( Wi-Fi Protected Access Pre-Shared Key) and WPA2-PSK, and also in the EAP ( Extensible Authentication Protocol Pre-Shared Key), and many others authentication mechanisms. A PSK is shared before being used and is held by both parties to the communication to authenticate each other, usually before other authentication methods such as usernames and passwords are applied. A Pre-Shared Key ( PSK) or also known as a shared secret is a string of characters that is used as an authentication key in cryptographic processes.
