The key generation process is identical to the process on a native Linux or Ubuntu installation. With SSH installed, run the SSH key generator by typing the following: ssh-keygen -t rsa You will be asked two questions. The first asks where to save the key, and you can press return to accept the default value. WPA, as part of the initial implementation of 802.11i, includes a host of new features designed to patch the gaping holes in the previous wireless encryption and authentication protocol, WEP.Wpa-psk, the less secure version of WPA for those of us who do not have a PEAP authentication server, relies upon a common pre-shared key to initialize the communication.
WPA PSK (Raw Key) Generator WPA-PSK (pre-shared key) mode, this is designed for home and small office networks and doesn't require an authentication server. Each wireless network device encrypts the network traffic by deriving its 128-bit encryption key from a 256 bit shared key. IPsec Pre-Shared Key Generator. PSK Generator provides a secure process to negotiate a 64-byte IPsec Pre-Shared Key (also known as a Shared Secret or PSK) through insecure means, such as email. Note: This page uses client side javascript. It does not transmit any entered or calculated information. Learn more about this PSK Generator. Dec 14, 2013 WPA configuration is handled seamlessly by the 'just works' WifiDocs/NetworkManager and should be installed with recent versions of Ubuntu. If not you can go through the procedure to install it manually here or you can configure the daemon in charge of WPA encryption (wpasupplicant) manually. Apr 12, 2018 SSH-key-based authentication provides a more secure alternative to password-based authentication. In this tutorial we'll learn how to set up SSH key-based authentication on an Ubuntu 16.04 installation.
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. 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.
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.
In this article, we will show you different ways to generate a strong Pre-Shared Key in Linux distributions.
1. Using OpenSSL Command
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. To generate a strong PSK use its rand sub-command which generates pseudo-random bytes and filter it through base64 encodings as shown.
2. Using GPG Command
GPG is a command-line tool to provide digital encryption and signing services using the OpenPGP standard. You can use its --gen-random option to generate a strong PSK and filter it through base64 encoding as shown.
In the following commands, 1 or 2 is the quality level and 10, 20, 40, and 70 are the character counts.
Generate PSK Key Using GPG Command
3. Using Pseudorandom Number Generators
You can also use any of the pseudorandom number generators in Linux such as /dev/random or /dev/urandom, as follows. The -c option of the head command helps to generate the number of characters.
4. Using date and sha245sum Commands
The date and sha256sum command can be combined to create a strong PSK as follows.

The above are some of the many ways of generating strong Pre-Shared Key in Linux. Do you know of any other methods? If yes, share it with us via the feedback form below.
SSH, the secure shell, is often used to access remote Linux systems. But its authentication mechanism, where a private local key is paired with a public remote key, is used to secure all kinds of online services, from GitHub and Launchpad to Linux running on Microsoft’s Azure cloud.
Generating these keys from Linux is easy, and thanks to Ubuntu on Windows, you can follow the same process from Windows 10. But even without Ubuntu, SSH keys can also be generated with the free and open source Windows application, PuTTy
Over the following few steps, we’ll guide you through the process of generating SSH keys using both Ubuntu on Windows and PuTTY.
Requirements
Wpa-psk Key Generator Ubuntu 10
All you need is a PC running Windows 10 and either of the following installed:
The puttygen.exe executable from PuTTY
Wpa2 Psk Generator
Wpa2 Psk Key
If you don’t already have Ubuntu on Windows, take a look at our Install Ubuntu on Windows 10 tutorial.
