SignXML: XML Signature in Python

SignXML is an implementation of the W3C XML Signature standard in Python (both “Second Edition” and Version 1.1). This standard (also known as XMLDSig and RFC 3275) is used to provide payload security in SAML 2.0, among other uses. SignXML implements all of the required components of the standard, and most recommended ones. Its features are:

Use of defusedxml.lxml to defend against common XML-based attacks when verifying signatures
Extensions to allow signing with and verifying X.509 certificate chains, including hostname/CN validation
Modern Python compatibility (2.7-3.4+ and PyPy)
Well-supported and reliable dependencies: lxml, defusedxml, cryptography, eight, pyOpenSSL
Comprehensive testing (including the XMLDSig interoperability suite) 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(signature_data)
xmldsig(root).sign(key=key, cert=cert)
xmldsig(root).verify()

Using a SAML metadata file:

from signxml import xmldsig

with open("metadata.xml", "rb") as fh:
    cert = etree.parse(fh).find("//ds:X509Certificate").text

root = ElementTree.fromstring(signature_data)
xmldsig(root).verify(x509_cert=cert)

See the API documentation for more.
