I don't think so.
I get
eth1      IEEE 802.11b  ESSID:"dd-wrt"  Nickname:""
          Mode:Managed  Frequency:2.437 GHz  Access Point: 00:16:B6:DA:56:B4
          Bit Rate:11 Mb/s   Sensitivity:1/3
          Retry limit:4   RTS thr:off   Fragment thr:off
          Encryption key:0000-0000-00   Security mode:open
          Power Management:off
          Link Quality=47/92  Signal level=-51 dBm  Noise level=-99 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:7
          Tx excessive retries:1  Invalid misc:0   Missed beacon:0
when I try a rather simple 10-digit WEP key.
