Configuring Wireless Encryption Settings
56 Sniffer Portable Professional
Use the Tools > Wireless > Encryption option (Figure 4-4) to specify
the encryption keys in use on wireless networks monitored by Sniffer
Portable Professional. If the correct keys are specified, Sniffer Portable
Professional can decrypt and decode both WPA-WPA2 and
WEP-encrypted packets during capture and postcapture.
The IEEE 802.11 Decryption Keys dialog box consists of two main areas:
Sniffer Portable Professional can decrypt both
WPA/WPA2 and WEP encrypted packets
simultaneously as long as you have enabled both
forms of decryption and configured their
associated keys correctly.
Use these options to specify the
keys to use for decryption of
WEP-encrypted data. WEP is an
early 802.11 encryption
technology and is not as
commonly seen as WPA-WPA2.
Use these options to specify
the passphrase used to
decrypt data on different SSIDs
(wireless networks).
WEP Keys – Use this panel to specify the WEP keys used to
encrypt data on the wireless network. You can specify either a
single set of keys for all channels or different keys for individual
channels. See Specifying WEP Keys on page 58.
WPA-WPA2 Keys – Use this panel to specify the pre-shared
passphrase corresponding to different SSIDs monitored by Sniffer
Portable Professional. See Specifying WPA-WPA2 Keys on page 57.
