wordpres 3 beta 2 auth auth key

ive found that for wordpress 3 beta 2 there is a bigger auth key in wp config

define(‘AUTH_KEY’, ‘put your unique phrase here’);
define(‘SECURE_AUTH_KEY’, ‘put your unique phrase here’);
define(‘LOGGED_IN_KEY’, ‘put your unique phrase here’);
define(‘NONCE_KEY’, ‘put your unique phrase here’);
define(‘AUTH_SALT’, ‘put your unique phrase here’);
define(‘SECURE_AUTH_SALT’, ‘put your unique phrase here’);
define(‘LOGGED_IN_SALT’, ‘put your unique phrase here’);
define(‘NONCE_SALT’, ‘put your unique phrase here’);

can i simply copy individual codes from the online key generator and put different code on each

put your unique phrase here

is that valid
