PCAP to Mermaid file parser

Description

Parser for .pcap files to Mermaid representation. This parser reads a .pcap file and outputs a Mermaid Sequence Diagram in the stdout of the console.

Usage

$ python3 parser.py -h

usage: parser.py [-h] [-c pkt_count] file_path

PCAP to Mermaid file parser

positional arguments:
  file_path             Path for the .pcap file to parse

optional arguments:
  -h, --help            show this help message and exit
  -c pkt_count, --count pkt_count
                        Number of packets to parse

Roadmap

Add live presentation after parsing the .pcap file
Add support fore more protocols
Add filters for the parsing like tcpdump filters
Add colored visual representation of the request and responses for each protocol
Add live packet capture and parsing of packets
