Installation of SSLyze

This part of the documentation covers the installation of SSLyze.

SSLyze can be installed on the following platforms:

  • Windows 10 (64 bits)

  • macOS Catalina

  • Linux (x86 and x86-64)

Other platforms (such as ARM-based platforms) are not supported.

Using pip

To install SSLyze, simply run this simple command in your terminal of choice:

$ pip install --upgrade setuptools
$ pip install sslyze

Using the source code

SSLyze is actively developed on GitHub.

You can clone the public repository:

$ git clone git://

Once you have a copy of the source, you can embed it in your own Python package, or install it into your site-packages easily:

$ cd sslyze
$ pip install .

Using the Windows executable

A pre-compiled Windows executable is available in the Releases page of the GitHub project.

This executable only gives access to the command line interface and does not allow using SSLyze’s Python API.

Using Docker

Warning: Docker support is experimental.

By default, the Docker image runs SSLyze with the -h flag:

$ docker run --rm -it nablac0d3/sslyze

Usage: sslyze [options]{ip} etc...
  --version             show program's version number and exit
  -h, --help            show this help message and exit

The image is intended to be run as an executable like so:

$ docker run --rm -it nablac0d3/sslyze --regular

You can create an alias for it by adding the following line to your shell’s rc file (e.g. ~/.bashrc):

$ alias 'sslyze'='docker run --rm -it nablac0d3/sslyze'
$ source ~/.bashrc
$ sslyze
