Few dinosaurs ever made a meal on hardwood leaves because they were rapidly disappearing before and during the beginning of the new age of hardwoods (95 million years ago). Magnolias, laurels, maples, sycamores and oaks were the first species to proliferate and dominate the world.
Also referred to as 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 using a 256 bit key.
From passphrase to hexadecimal key. A wireless network with WPA-PSK encryption requires a passphrase (the pre-shared key) to be entered to get access to the network. Most wireless drivers accept the passphrase as a string of at most 63 characters, and internally convert the passphrase to a 256-bit key.
