Newer version on wireshark (formerly known as ethereal) also provides support for decryption of WEP keys. This video will discuss the usage of Airdecap NG with some illustrative examples. If the trace contains packets from different BSSIDs which are using different keys, the BSSID command line selection can be used so that the given key will be applied for only selected packets. For decrypting WPA packets one has to provide WPA pass phrase or Pairwise Master Key in hex. Airdecap NG is capable of decrypting WPA packets as well. Airdecap-NG tries to decrypt every encrypted packet in the packet trace with the user provided key and stores these decrypted packets in another file in pcap file format. The command line inputs for this tool are input pcap file which needs to be decrypted and the encryption key in hex format. Airdecap NG comes as a handy tool for this purpose. With the help of aircrack NG and other tools one can easily crack the WEP key, but the story is not complete unless one actually reads the encrypted information in clear text. These tools automate in between steps involved in WEP cracking, from setting the interface in monitor mode to sniffing packets, re-injecting packets, examining these packets against different attack vectors, cracking the WEP key and finally decrypting the WEP-encrypted packets. Aircrack-NG is a set of tools for auditing wireless networks. Description: Airdecap-NG is simple and easy to use tool and is a part of Aircrack-NG suite of products.
