"On behalf of expertvillage.com my name is David and I am here to tell you about security on your wireless system. Now, with the WPA settings it is more secure. You do need to at least have 20 digits and you can use the digits 0 through 9 or A through F. and you can go all the way up to 24 hexidecimal. Anywhere within that range for a single key. So you are not stuck to only having 10, 26 or 58. You have a lot wider variety on what your pass codes or passwords will be to be able to access the system, making it a much secure system, however, WPA is the less commonly used and the average person uses the WEP keys with either 10 to 26 digits."
