# Release and tagging
|
|
|
|
- Current version of ssldump is [v1.8](https://github.com/adulau/ssldump/releases/tag/v1.8) (released: 2023-08-14) - [ChangeLog](https://raw.githubusercontent.com/adulau/ssldump/master/ChangeLog)

# What about the original ssldump?
|
|
|
|
This repository is composed of the original SSLDUMP 0.9b3 + a myriad of patches (from Debian and other distributions) + contributions via PR
|
|
|
|
ssldump is an SSLv3/TLS network protocol analyzer. It identifies TCP
|
|
connections on the chosen network interface and attempts to interpret
|
|
them as SSLv3/TLS traffic. When it identifies SSLv3/TLS traffic, it
|
|
decodes the records and displays them in a textual form to stdout. If
|
|
provided with the appropriate keying material, it will also decrypt
|
|
the connections and display the application data traffic. It also
|
|
includes a JSON output option, supports [JA3](https://github.com/salesforce/ja3) and IPv6.
|
|
|
|
# How to do I run ssldump?
|
|
|
|
`./ssldump -j -ANH -n -i any | jq` will run ssldump on all interfaces and output the result in JSON format including ja3 hashes.
|
|
|
|
For more details, check the man page.
|
|
|
|
## How can I lookup ja3 hashes?
|
|
|
|
This example will query ja3er.com service to display the known ja3 hashes from the TLS handshaked in the pcap.
|
|
|
|
`./ssldump -r yourcapture.pcap -j | jq -r 'select(.ja3_fp != null) | .ja3_fp' | parallel 'curl -s -X GET 'https://ja3er.com/search/{}' | jq .'`
|
|
|
|
# Why do you maintain this repository?
|
|
|
|
Because it's a mess. The software maintenance process for old free (unmaintained) software
|
|
like ssldump is a complete chaotic process. I do this to ease my pain and this could help
|
|
other too (but this is just a collateral damage).
|
|
|
|
# Where ssldump is used?
|
|
|
|
- I used it for a relatively small project called Passive SSL. For more information, [Passive SSL Passive Detection and Reconnaissance Techniques, to Find, Track, and Attribute Vulnerable ”Devices”](https://www.first.org/resources/papers/conf2015/first_2015_-_leverett_-_dulaunoy_-_passive_detection_20150604.pdf). Additional back-end code available is in the [crl-monitor ](https://github.com/adulau/crl-monitor/tree/master/bin/x509) repository.
|
|
- ssldump is used in the [D4-Project](https://github.com/D4-project/).

The "save to pcap" (-w) option by @ryabkov, is heavily based on the work of
