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.
OpenSSL will ask for password which is used to derive a key as well the initialization vector. Since encryption is the default, it is not necessary to use the -e option. Use a given Key. It also possible to specify the key directly. For most modes of operations (i.e. All non-ECB modes) it is then necessary to specify an initialization vector. 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. The program can be called either as openssl ciphername or openssl enc -ciphername. A password will be prompted for to derive the key and IV if necessary. The -salt option should ALWAYS be used if the key is being derived from a password unless you want compatibility with previous versions of OpenSSL and SSLeay. Without the -salt option it is possible to perform efficient dictionary.

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.

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.
