Python sign SOAP request using BinarySecurityToken

Python sign SOAP request using BinarySecurityToken

Signing a SOAP request using a BinarySecurityToken involves creating a digital signature for the SOAP message using the token's credentials. To achieve this, you typically need to construct the SOAP envelope, generate the necessary XML structures for the security header, and sign the request accordingly. Here's a general outline of how to do it:

  1. Create the SOAP Envelope: Build the SOAP envelope with the required headers, body, and payload.

  2. Generate Security Header with BinarySecurityToken: Construct the security header that includes the BinarySecurityToken element containing your credentials. This is typically done using XML libraries such as xml.etree.ElementTree or third-party libraries like lxml.

  3. Sign the Request: Use a cryptographic library like cryptography to generate the digital signature of the entire SOAP message or specific parts of it. You will typically use the private key corresponding to the public key associated with the BinarySecurityToken.

  4. Include the Signature in the Security Header: Insert the generated digital signature into the security header.

  5. Send the Signed SOAP Request: Finally, send the signed SOAP request to the server.

Here's a simplified example using Python's built-in xml.etree.ElementTree and cryptography libraries:

import xml.etree.ElementTree as ET from cryptography.hazmat.backends import default_backend from cryptography.hazmat.primitives import serialization from cryptography.hazmat.primitives import hashes from cryptography.hazmat.primitives.asymmetric import padding # Create SOAP envelope soap_envelope = ET.Element("soapenv:Envelope", xmlns="...", soapenv="...") body = ET.SubElement(soap_envelope, "soapenv:Body") # Generate BinarySecurityToken and Security header binary_security_token = ET.Element("wsse:BinarySecurityToken", ValueType="...", EncodingType="...", wsse="...") security = ET.Element("wsse:Security", mustUnderstand="1", soapenv="...") security.append(binary_security_token) soap_envelope.insert(0, security) # Convert private key to a usable format (replace with actual key data) private_key_data = b"..." private_key = serialization.load_pem_private_key(private_key_data, password=None, backend=default_backend()) # Serialize the SOAP request soap_request = ET.tostring(soap_envelope, encoding="unicode") # Sign the request signature = private_key.sign(soap_request.encode(), padding.PKCS1v15(), hashes.SHA256()) # Include the signature in the Security header signed_info = ET.Element("ds:SignedInfo", xmlns:ds="...") reference = ET.Element("ds:Reference", URI="#...", ds="...") digest_value = ET.Element("ds:DigestValue", ds="...") reference.append(digest_value) signed_info.append(reference) security.insert(1, signed_info) # Serialize the updated SOAP request signed_soap_request = ET.tostring(soap_envelope, encoding="unicode") # Now you can send the signed SOAP request to the server print(signed_soap_request)

Please note that this example is a simplified illustration of the process and might need adjustments to work with your specific SOAP service and authentication requirements. Additionally, the libraries used may vary depending on your project's needs.
