Sandra, a wireless-network auditor, discovers that her client uses WEP. To demonstrate that WEP encryption is very weak, she wants to decrypt some WEP packets. She successfully captures the WEP data packets but cannot access their contents because the data is encrypted.

Which of the following will help Sandra decrypt the data packets without knowing the key?
