h21lab / json2pcap Goto Github PK

Hi! I have a capture file with embedded decryption secrets, which I exported as a JSON file. I was hoping this project could reconstruct a pcap with the JSON data, but the generated file only displays [Malformed Packet] information.

Is this a feature you are considering in the future?

Follow up to #5

1. Any plans to update the version in the Wireshark repository - tools/json2pcap/json2pcap.py ?
2. Is json2pcap a possible solution to Export PCAP containing decrypted traffic?

The http information is in the JSON output but json2pcap produces a garbled pcap:

No.	Time	Source	Destination	Protocol	Length	Info
8	0.003271	1b:38:67:ef:04:a6	14:00:00:0c:85:90	0x4acc	201	Ethernet II
9	0.004183	e7:10:24:77:49:b5	14:00:00:0c:3b:fa	0xdcf1	301	Ethernet II
10	0.004814	48:54:54:50:2f:31	47:45:54:20:2f:20	0x2e30	119	Ethernet II
11	0.005169	2e:30:20:32:30:30	48:54:54:50:2f:31	0x206f	4427	Ethernet II

The output above is from Files: dump.pcapng, premaster.txt from the Wireshark Wiki Sample Captures - SSL with decryption keys

Converting from .pcap to .json and then back to .pcap without touching, although file size remain exactly same, but the source mac of all packets all became '00:a0:20:08:00:00', while destination mac address all became '00:00:24:00:24:40'?

Hi,

I tried to use your code, but I get the following error:

Traceback (most recent call last): File "./json2pcap.py", line 645, in <module> new_packet.time = float(frame_time) NameError: name 'frame_time' is not defined
The only thing I changed into my code was the #!/usr/bin/python3, not sur eif this supports python3. this is the ocmmand I run:

/json2pcap.py -i ~/pcaps/dtag/poc/sample_pcap/test3.json -o test.pcap

Is there an additional parameter I should pass? I only intend to convert back a dissected json into pcap.
