# Parsing 802.11 Handshake / EAPOL Frames
This example shows the reader how to parse 802.11 Handshakes from a pcap, outputting the EAPOL version, type, length, and data such as Nonce, IV, MIC and EAPOL Key Data.
# Building and Using
```
>> cd examples/parse_eapol/
>> make
clang -Wall -Werror -O3 -o parse_eapol -c -o parse_eapol.o parse_eapol.c
clang -Wall -Werror -O3 -o parse_eapol parse_eapol.c -lpcap -lwifi
>> ./parse_eapol --file ~/libwifi-handshake.pcap
