Objet : Testing WEP Key on pcap dump


Does anyone know of a quick method or automated tool for accomplishing the
following: I have a pcap dump using Kismet Wireless sniffer on a BSSID using
128-bit WEP encryption.  If I think I know the 26 character HEX WEP key, is
there a way to easily decrypt all of the traffic for a specific BSSID based
on input of this WEP key, and then display the decrypted pcap output in
Ethereal?  Or another way of seeing if this WEP key is able to decrypt from
the pcap dump for that specific BSSID?

Jason
