How do I remove headers to get only the encrypted portion

pcap = rdpcap(".pcap file")

for pkt in pcap:
    if Raw in pkt:
        f=pkt[Raw]
        print f

The above code gives the output as shown below:

HTTP/1.1 200 OK

Content-Type: text/html; charset=utf-8

How can I remove the headers such that the output is just:

?}k{?H????+0?#!?,_???$?:?7vf?w?Hb???ƊG???9???/9U?\$;3{9g?ycAӗ???????W{?o?~?FZ?e ]>??<??n????׻?????????d?t??a?3?

Solution

Make sure you are using Scapy 2.4.3
Load the http layer before reading the pcap: from scapy.layers.http import *
read the pcap
You'll get the output you're looking for as the raw layer

Note: you can turn off auto decompression using

conf.contribs["http"]["auto_compression"] = True

Moreover it's possible to automatically match the fragments / chunks (not used here). See sniff with "TCPSession " at https://scapy.readthedocs.io/en/latest/layers/http.html
