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) 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 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()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(data)
xmldsig(root).verify(x509_cert=cert)See the API documentation for more.
