Preshared Key: A cryptographic key that is shared between parties before it is used for encryption or authentication purposes. PSKs are commonly used in various forms of secure communication methods, such as wireless networks (like WPA-PSK in Wi-Fi networks) or in VPN connections, to establish a secure channel over an otherwise insecure medium. Despite its simplicity and efficiency, PSK should be used with caution due to potential security risks if the key is compromised.
