AttributeError: 'BinarySignature' object has no attribute 'egress'

Hi!!

zeep version 4.1.0

I am trying to add security headers exactly BinarySecurityToken and to be able to sign the headers of the worst adressing when using the BinarySignature plugin I get the following error: AttributeError: 'BinarySignature' object has no attribute 'egress'

This is the code I'm using:

`
   import shutil

from zeep import Client, Settings, Transport, wsse
from OpenSSL import crypto
from zeep.wsa import WsAddressingPlugin
from lxml.builder import ElementMaker
import logging.config

from pathlib import Path

from zeep.wsse import Signature, BinarySignature

from transport_with_attach import TransportWithAttach

logging.config.dictConfig({
    'version': 1,
    'formatters': {
        'verbose': {
            'format': '%(name)s: %(message)s'
        }
    },
    'handlers': {
        'console': {
            'level': 'DEBUG',

        },
    },

    }
})

    key = crypto.dump_privatekey(crypto.FILETYPE_PEM, p12.get_privatekey())

    with open('cert.pem', 'wb') as f:
        f.write(cert)
    with open('key.pem', 'wb') as f:

    session.cert = ('./cert.pem', './key.pem')

` I get this error:

AttributeError: 'BinarySignature' object has no attribute 'egress'

I can't even create a request.

Thanks very much for any info!

Hi! Can you resolve this issue with the BinarySignature?

[gevezex]

Is there any progress regarding this issue?

using BinarySignature(...) for the wsse parameter, rather than in the plugin array fixed this for me, and works as intended, as far as i can tell
