Documentation

A documentation for xmlsec can be found at xmlsec.readthedocs.io <https://xmlsec.readthedocs.io/>_.

Usage

Check the examples <https://xmlsec.readthedocs.io/en/latest/examples.html>_ section in the documentation to see various examples of signing and verifying using the library.

Requirements

• libxml2 >= 2.9.1
• libxmlsec1 >= 1.2.33

Install

xmlsec is available on PyPI:

.. code-block:: bash

pip install xmlsec

Depending on your OS, you may need to install the required native libraries first:

Linux (Debian) ^^^^^^^^^^^^^^

.. code-block:: bash

apt-get install pkg-config libxml2-dev libxmlsec1-dev libxmlsec1-openssl

Note: There is no required version of LibXML2 for Ubuntu Precise, so you need to download and install it manually.

.. code-block:: bash

wget http://xmlsoft.org/sources/libxml2-2.9.1.tar.gz tar -xvf libxml2-2.9.1.tar.gz cd libxml2-2.9.1 ./configure && make && make install

Linux (CentOS) ^^^^^^^^^^^^^^

.. code-block:: bash

yum install libxml2-devel xmlsec1-devel xmlsec1-openssl-devel libtool-ltdl-devel

Linux (Fedora) ^^^^^^^^^^^^^^

.. code-block:: bash

dnf install libxml2-devel xmlsec1-devel xmlsec1-openssl-devel libtool-ltdl-devel

Mac ^^^

.. code-block:: bash

brew install libxml2 libxmlsec1 pkg-config

Alpine ^^^^^^

.. code-block:: bash

apk add build-base libressl libffi-dev libressl-dev libxslt-dev libxml2-dev xmlsec-dev xmlsec

Troubleshooting

Mac ^^^

If you get any fatal errors about missing .h files, update your C_INCLUDE_PATH environment variable to include the appropriate files from the libxml2 and libxmlsec1 libraries.

Windows ^^^^^^^

Starting with 1.3.7, prebuilt wheels are available for Windows, so running pip install xmlsec should suffice. If you want to build from source:

. Configure build environment, see wiki.python.org <https://wiki.python.org/moin/WindowsCompilers>_ for more details.

. Install from source dist:

.. code-block:: bash

  pip install xmlsec --no-binary=xmlsec

Building from source

. Clone the xmlsec source code repository to your local computer.

.. code-block:: bash

  git clone https://github.com/xmlsec/python-xmlsec.git

. Change into the python-xmlsec root directory.

.. code-block:: bash

  cd /path/to/xmlsec

. Install the project and all its dependencies using pip.

.. code-block:: bash

  pip install .

Contributing

Setting up your environment ^^^^^^^^^^^^^^^^^^^^^^^^^^^

. Follow steps 1 and 2 of the manual installation instructions <#building-from-source>_.

. Initialize a virtual environment to develop in.

This is done so as to ensure every contributor is working with close-to-identicial versions of packages.

.. code-block:: bash

  mkvirtualenv xmlsec

The mkvirtualenv command is available from virtualenvwrapper package which can be installed by following link <http://virtualenvwrapper.readthedocs.org/en/latest/install.html#basic-installation>_.

. Activate the created virtual environment:

.. code-block:: bash

  workon xmlsec

. Install xmlsec in development mode with testing enabled.

This will download all dependencies required for running the unit tests.

.. code-block:: bash

  pip install -r requirements-test.txt
  pip install -e "."

Running the test suite ^^^^^^^^^^^^^^^^^^^^^^

. Set up your environment <#setting-up-your-environment>_.

. Run the unit tests.

.. code-block:: bash

  pytest tests

. Tests configuration

Env variable PYXMLSEC_TEST_ITERATIONS specifies number of test iterations to detect memory leaks.

Reporting an issue ^^^^^^^^^^^^^^^^^^

Please attach the output of following information:

• version of xmlsec
• version of libxmlsec1
• version of libxml2

• output from the command

  .. code-block:: bash

  pkg-config --cflags xmlsec1
