===Decrypting===

Decryption often requires 2 tools; 1 for gathering packets and another for analysing the packet and determining the key. Gathering packets may be done through tools such as [[WireShark]] or Prismdump and cracking may be done through tools such as WEPCrack, [[AirSnort]], AirCrack, and WEPLab.

When gathering packets, often a great amount of them are required to perform cracking. Depending on the attack used, 5-16 million frames may be required. The attack command itself, however, is surprisingly simple.

Line 25:

Commands to be inputted into WEPCrack are:

<syntaxhighlight lang="console">

$ perl \progra~1\wepcrack\pcap-getIV.pl

</syntaxhighlight>

This command generates a log-file (ivfile.log) from a captured packet obtained by WireShark or prismdump A packet with at least 5 million frames is required.

<syntaxhighlight lang="console">

$ perl \progra~1\wepcrack\wepcrack\.pl ivfile.log

</syntaxhighlight>

This command asks WEPCrack to determine the key from the log file.<ref>{{Cite book |last=Beaver |first=Kevin |title=Hacking Wireless Networks forFor Dummies |last2=Davis |first2=Peter |publisher=[[For Dummies]] |year=2005 |isbn=978-0764597305 |edition=1st}}</ref>

AirSnort is a software program that passively collects traffic on an even[[IEEE simpler802.11b]] programnetwork.
