signxml 0.1.0

A sane XML Signature (xmldsig) extension for defusedxml ElementTree

SignXML is an implementation of the W3C XML Signature standard in Python. This standard (also known as XMLDSig) is used to provide payload security in SAML 2.0, among other uses. SignXML implements all of the required components of the standard. Its features are:

• Extensions to allow the use of stronger hash functions (e.g. SHA256 instead of SHA1)

• Extensions to allow signing with and verifying X.509 certificate chains, including hostname/CN validation

• Modern Python compatibility (2.7-3.4+ and PyPy)

• Minimal and reliable dependency footprint: lxml, pycrypto, eight, pyOpenSSL

• Comprehensive testing and continuous integration

• Simple interface with useful defaults

• Compactness, readability, and extensibility

Installation

pip install signxml

Synopsis

from signxml import xmldsig

cert = open("example.pem").read()
key = open("example.key").read()
root = ElementTree.fromstring(data)
xmldsig(root).sign(key=key, cert=cert)
xmldsig(root).verify()
