XAdES: Python native XAdES Signature

A python native library that signs and verifies XAdES signatures

Highlights:

• Build on top of lxml, cryptography and xmlsig

Status

Installation

pip install xades

Usage

import xades
import xmlsig

sign = xmlsig.template.create(c14n_method=xmlsig.constants.TransformExclC14N, sign_method=xmlsig.constants.TransformRsaSha1)
ref = xmlsig.template.add_reference(sign, xmlsig.constants.TransformSha1)
xmlsig.template.add_transform(ref, xmlsig.constants.TransformEnveloped)
qualifying = template.create_qualifying_properties(signature)
props = template.create_signed_properties(qualifying)
policy = xades.policy.GenericPolicyId(
          policy_id,
          policy_name,
          xmlsig.constants.TransformSha1)
ctx = xades.XAdESContext(policy)
