pyas2's Issues

Keep the original filename

Is it possible to keep the original filename when the server receives the message.

Thanks

SuspiciousFileOperation at /admin/pyas2/privatecertificate/add/

Hi there,

When uploading the private key I get this error.

The joined path (/pyas2/certificates/as2_private.pem) is located outside of the base path component (/media)

It seems that's due to this line below but I'm left wondering how this hasn't come up before? It feels to me like it would be better to reference the path to these keys in the settings dict rather than using upload in admin?

Here is the log messages from pyas2 admin:

SOLUTION

The problem originates from table pyas2_message, column mdn_mode. Here the options from models.py can only be "ASYNC" or "SYNC". varchar(2) will not be enough to hold either of these values and needs to be updated to at least varchar(5). After changing to varchar(5). The issue is eliminated.

Thanks!

Hashing algorithms other than sha-1

Hi there, is anyone working on or planning to work on sha-256 or sha-512 hashing? I am looking at integrating with a partner who does not accept sha-1.

I would be willing to help if someone is starting on this project or I could work on it if someone can give me advice :)

Bug? I see a stack trace when running in daemon mode

Hi,

Is it possible to customize the message of the MDN.

Thanks

Running pyas2 on Heroku

Has anyone ran this server on Heroku?

I am getting the following error which is similar to #30 but I think the solution will have to be different because the way Heroku installs packages.

Signature Verification Failures

Facing signature varification failures when testing with Mendelson AS2.

@klaasfeenstra, Can you please provide details of the error you are facing so that we can track and fix this bug.

error while inbound

Use PYASN1 for signing and verification

The latest update of pyasn1 is able to parse the pkcs7 data, so in effect we should be ablt to extract the signatures and then verify them.

This will mean that we have full control over signing such as hashing algrithm used and other factors that are not exposed by M2Crypto

pyas2 built-in web server fails with chunked encoding transfer

When receiving messages from MS Biztalk, we occasionally see this error during decryption:

An error occurred during the AS2 message processing: Failed to decrypt message, exception message is header too long

the debug output doesn't show any particular AS2 protocol header that's too long, so maybe its' some other header. What is strange is that the debug log does not show the raw contents that were received.

e.g. failed log shows this:

Signature not being recognized as SHA-1

Hello,

This may be related to Issue #6.

I am again continuing to test with Mendelson's provided test server. The details for this free service can be found here:

http://as2.mendelson-e-c.com/

When selecting SHA-1 in the partner configuration page under MDN Settings in the pyas2 admin, it does not seem that is what the partner is recognizing as the used hash algorithm. For some reason they are recognizing it as SHA-256. Please see the screenshot below and take notice of the last row that is highlighted.

If you look at some of the other rows above, you can see that others have submitted signatures that are recognized as SHA-1.

I think the issue might be in the header. Mendelson interprets the pyas2 sent header as:

as2-version = 1.2
content-length = 3853
disposition-notification-to = [email protected]
accept = */*
recipient-address = http://testas2.mendelson-e-c.com:8080/as2/HttpReceiver
ediint-features = CEM
message-id = <20150629010101.1725.34375@Q6-EDI>
mime-version = 1.0
content-type = application/pkcs7-mime; smime-type="enveloped-data"; name="smime.p7m"
as2-from = mycompanyAS2
disposition-notification-options = signed-receipt-protocol=required, pkcs7-signature; signed-receipt-micalg=optional, sha1

user-agent = PYAS2, A pythonic AS2 server
date = Sun, 28 Jun 2015 20:01:01 -0500

other senders where SHA-1 is identified are interpreted as:

content-type = application/pkcs7-mime; smime-type=enveloped-data; name=smime.p7m

mime-version = 1.0
as2-from = mycompanyAS2
content-type = application/pkcs7-mime; smime-type=enveloped-data; name="smime.p7m"

I am still trying to go through the RFC specs for S/MIME, but if anything jumps out at you as to what would cause the sender to misinterpret the hash algorithm used, then please let me know.

Here is also a senders RAW decrypted message as interpreted by Mendelson:

Here is the pyas2 RAW decrypted message:

missing setup.py

when i look here on github.com in the project repo i see no setup.py, but if i download the .tar.gz from pypi i do see it. any ideas why it doesn't exist here in the repo?

I'm trying to install the project in develop mode to make some changes

implement UI option to disable certificate chain verification during payload verification

when receiving payloads signed by an invalid certificate chain (e.g. a self-signed one), the verification will fail. Please implement a UI option that would disable certificate chain verification while still verifying the payload.

Sending message between two PYAS2 server

I have setup two PYAS2 servers and trying to send a message between the two I followed the instructions here in this Quick Start Guide http://pyas2.readthedocs.io/en/latest/quick-start-guide.html#

I can't get it to work. When trying to send a file this is how far it gets

I checked the logs for both the application and server. Application log only shows the Send message started with parameters: {parameters} and the server log is empty

I see that logging is set to INFO. Where can I change the log level of the application?

Here is the screenshot

-

any reference how do i export this files into readable.. or some document on how to start on inbound data.

Message List Paging with Filters

Paging on the messages list is broken when using filters. The next page link is hard-coded to use ?page=2. The link should also use all other URL queries to maintain filters.

Example: The URL for page 1 of inbound messages is /pyas2/message/?direction=IN. The next page button takes you to /pyas2/message/?page=2. It should instead take you to /pyas2/message/?direction=IN&page=2.

Any plans to support SHA-2?

I'm considering trying out pyAS2, but SHA-2 (or SHA256) is not mentioned in the supported list.

call_command instead of subprocess.Popen

Django provides a builtin function for calling commands django.core.management.call_command
Is there something that Popen is providing in this case that call_command does not? Looking to see if I am missing something obvious.

python_executable_path = pyas2init.gsettings['python_path']
managepy_path = pyas2init.gsettings['managepy_path']
...
lijst = [
    python_executable_path,
    managepy_path,
    'sendas2message',
    '--delete',
    form.cleaned_data['organization'],
    form.cleaned_data['partner'],
    temp.name
]
subprocess.Popen(lijst).pid

Can be simplified by using:

kwargs = {
    'delete': delete,
    'organization_as2name': form.cleaned_data['organization'],
    'partner_as2name': form.cleaned_data['partner'],
    'path_to_payload': temp.name
}
call_command('sendas2message', **kwargs)

runas2server fails to start with CherryPy >= 9

with fresh install, cherrypy is installed with version above 10. However, wsgiserver was moved to cheroot as of version 9 forward -> http://docs.cherrypy.org/en/latest/history.html

Workaround: install cherrypy with version >=8, <=9.0a0

UI is not the same as the one from the documentation

Hi,

I have followed the installation instructions from the doc. But when I access to the UI, I dont have the same as the one in the doc. I don't have the logo, name of the server, all the tabs (run, etc...). I have only the "pyAS2 Global Settings" and a tab Home which redirect to the Django admin page...

My server is on Linux Fedora 23 Server. Python version is 2.7.10 and the Django version is 1.9.3.

Could you help & advise.
Thanks

Fred

Certificate Problems - Question

I am fairly new to the AS2 game, and your software has been the first I have been able to get up and running. However, I am having the below issues that I would very much appreciate your help with.

When testing with Mendelson's test server (Here is info regarding the test server: http://as2.mendelson-e-c.com/), I keep receiving the following openssl error:

Failed to send message, error is 140647279224640:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:703:Expecting: CERTIFICATE

I have extracted the sender key and certificate provided by mendelson (key1.pfx) using:

certificate:
openssl pkcs12 -in key1.pfx -nokeys -out cert.pem

key (used -des3 to maintain password on key):
openssl pkcs12 -in key1.pfx -nocerts -out key.pem -nodes -des3

If I don't sign the AS2 test message, then the message is sent. However, no data is sent with message and the server outputs:

20150627 11:06:14 DEBUG    : Sender Mic content 
None
20150627 11:06:49 INFO     : Send message started with parameters: "['/usr/bin/python', '/home/django/django_pyas2/manage.py', 'sendas2message', u'mycompanyAS2', u'mendelsontestAS2', u'/tmp/test.txtqMpVir']"
System check identified some issues:

WARNINGS:
?: (1_6.W001) Some project unittests may not execute as expected.
HINT: Django 1.6 introduced a new default test runner. It looks like this project was generated using Django 1.5 or earlier. You should ensure your tests are all running & behaving as expected. See https://docs.djangoproject.com/en/dev/releases/1.6/#new-test-runner for more information.

This may be because the mendelson test server requires messages to be signed, but from the my server's output, it seems that the uploaded test file is not being retrieved when pyas2 is sending the message. Checking the tmp folder, I am able to see all of the files I have uploaded.

So right now I am able to send an unsigned encrypted message to Mendelson's test server, but with no data. Again, I am not able to send a signed message because of the certificate issues above.

I am using:

Ubuntu 14.04 (all software is installed globally ~ no virtualenv)
python 2.7
Django 1.7.8
cherryPy 3.7.0

Thank you for any input you may be able to provide and thank you for the software. :)

Hello,

I installed 2 pyas2 server and configured them based on the documentation.

When I try to send Messages I get the same error on both systems shown in the logs:

Add support for text/CSV

Hey I'd like to add support for csv files; I'll open a PR in a second. Would appreciate feedback and advice for implementing it.

"python <defunct>" jobs when multiple files are sent to pyas2

When pyas2 picks up one file at a time I have no problems. When multiple files are put in the outbound folder it sometimes doesn't process them until I "touch" all the files to update the timestamp. When it does process them as a batch I'm left with a "python " job for each file. After several defunct jobs build up I have to restart pyas2 for it to function automatically again.

Payload not viewable after signature verification error

When receiving a message from a partner I get an error: Signature Verification Failed, exception message is certificate verify error.

I can see the MDN I sent back, but the original incoming message isn't saved to a file, and isn't viewable in messages page.

when to support the python 3？

it's too difficult to setup the pyas2 ，especially M2crpto in python2，so when to support the python 3？

Setting up pyAS2 on Ubuntu

Since I can't get it to work on Windows I figure I try on Ubuntu. I'm a newby to Linux to bear with me.

I have everything setup up until I need to run the following

python manage.py migrate

I get

python: can't open file 'manage.py': [Errno 2] No such file or directory

Does not help either when I change the path to /usr/local/lib/python2.7/dist-packages/django or /usr/local/lib/python2.7/dist-packages/pyas2

Cherrypy

Cherrypy is also a dependency, should be added in the documentation.

I can see it successfully install pyas2, django and m2crypto but when I open the python shell and try an import of pyas2 I get:

python
Python 2.7.15 (default, Nov 28 2018, 22:38:08)

following the steps in the installation doc I can create the django project but when I try to run the manage.py migrate command I get the following error:

Unwilling to be beaten I tried downloading the package from pypi and running the setup.py in the download:

https://pypi.org/project/pyAS2/#files

if I run it with the setup.py install --user command it seems to install successfully and I'm able to import pyas2 in the python shell.

I'm also able to continue the setup process and the python manage.py migrate command runs as you'd expect.

I'm ok with this for the time being but I'm curious about why the pip install doesn't work. I'm not sure where the import issue is but I'll research more and see if I can find a fix. If someone else can think of another fix to allow me to install with pip so I can put this in my virtualenv I'd appreciate the help.

If it's something obvious I'm missing I'd be happy to update the documentation with details to get around it.

Thanks for this package by the way! I'm thrilled to start using it.

Binary payload

Hi,

At the moment, we can't use pyas2 with one of our client because signing failed with binary payload. Is Could you implement binary payload?

Thanks

partner public key using Go Daddy chained certificate doesn't seem to work

Sorry this isn't really a bug but I do not know where else to ask the question

I have a trading partner using their Go Daddy web certificate to sign messages in thier MS Biztalk server

When I load just their certificate in pem format, decode fails with this error:

An error occurred during the AS2 message processing: Signature Verification Failed, exception message is certificate verify error

I see that their certificate uses a chain file. When I try loading the 'gd_intermediate' certificate into "Local CA Store", decoding still fails.

This is a huge company, an M$ only shop, I doubt I can get them to change their certificate. Do you have any idea how I can get PyAS2 to work with their existing Go Daddy certificate?

Thanks for any suggestions..
