Postcapture WEP Decryption

The Sniffer software can decrypt and decode WEP-encrypted packets either

during or after capture. As described in Setting Encryption Options on page 85,

you use the Encryption options in the 802.11 tab of the Options dialog box to

configure the automatic decryption of WEP-encrypted data during capture.

However, you can also perform WEP decryption on trace files containing

frames encrypted with a known WEP key set but not decrypted during capture.

This section describes how.

To perform offline decryption of WEP-encrypted data:

1 Display the Decode tab of a trace file or capture buffer containing

frames encrypted with a known WEP key set but not decrypted during

capture.

Figure 10-13 shows the Decode tab of a saved trace file from a wireless

LAN.
