python-xmlsec

Python bindings for the XML Security Library.

Documentation

Documentation for xmlsec can be found at xmlsec.readthedocs.io.

Usage

Check the examples 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:

pip install xmlsec

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

Linux (Debian)

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.

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)

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

Linux (Fedora)

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

Mac

brew install libxml2 libxmlsec1 pkg-config

or

port install libxml2 xmlsec pkgconfig

Alpine

apk add build-base openssl libffi-dev openssl-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:

1. Configure build environment, see wiki.python.org for more details.

2. Install from source dist:

   pip install xmlsec --no-binary=xmlsec
   

Building from source

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

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

2. Change into the python-xmlsec root directory.

   cd /path/to/xmlsec
   

3. Install the project and all its dependencies using pip.

   pip install .
   

Contributing

Setting up your environment

1. Follow steps 1 and 2 of the manual installation instructions.

2. Initialize a virtual environment to develop in. This is done so as to ensure every contributor is working with close-to-identical versions of packages.

   mkvirtualenv xmlsec
   

   The mkvirtualenv command is available from virtualenvwrapper package which can be installed by following link.

3. Activate the created virtual environment:

   workon xmlsec
   

4. Install xmlsec in development mode with testing enabled. This will download all dependencies required for running the unit tests.

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

Running the test suite

1. Set up your environment.

2. Run the unit tests.

   pytest tests
   

3. 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

  pkg-config --cflags xmlsec1
