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.

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 do you use ssldump?

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”. Additional back-end code available is in the crl-monitor repository.

Build instructions

On Debian & Ubuntu:

apt install build-essential autoconf libssl-dev libpcap-dev libnet1-dev libjson-c-dev
./autogen.sh
./configure --prefix=/usr/local
make
(optional) make install

On Fedora, Centos & RHEL:

dnf install autoconf automake gcc make openssl-devel libpcap-devel libnet-devel json-c-devel
./autogen.sh
./configure --prefix=/usr/local
make
(optional) make install

Optional configuration features (aka ./configure options):

  --disable-optimization  disable compiler optimizations (change from -O2 to -O0)
  --enable-debug	  enable debug info (add "-g -DDEBUG" to CFLAGS)
  --enable-asan		  enable AddressSanitizer and other checks
	add "-fsanitize=address,undefined,leak -Wformat -Werror=format-security
		-Werror=array-bounds" to CFLAGS
	use libasan with GCC and embedded ASAN with Clang

Configuration examples:

- Use GCC with libasan, debug info and custom CFLAGS:
	./configure CC=/usr/bin/gcc --enable-asan --enable-debug CFLAGS="-Wall"

- Use Clang with ASAN and no optimizations (-O0)
	./configure CC=/usr/bin/clang --enable-asan --disable-optimization

Notes

The "save to pcap" (-w) option by @ryabkov, is heavily based on the work of @droe on https://github.com/droe/sslsplit .
