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 Wikipedia, the free encyclopedia. In cryptography, a pre-shared key (PSK) is a shared secret which was previously shared between the two parties using some secure channel before it needs to be used. To build a key from shared secret, the key derivation function is typically used. Such systems almost always use symmetric key cryptographic algorithms.
