Akamai Authorization Token for Python

edgeauth-token-python's Issues

Is Python 3.7 supported?

What about support for Python 3.7?

-s doesn't accept an int

Hello,
Hhen parsing option -s: its parameter is parsed as string line 218
later it's assigned without a cast line 53
then it's compared to string now and (in that case it's overwritten with an int) or it's verified that it can be cast to a positive integer line 72
So far so good.

Problem is that it's not cast to an int when trying to add it to window_second line 103 and when comparing it to end time line 108
A fix consist in casting it to an int in these lines

Another option maybe more consistent with what is done when it's now would consist in overwriting the string by an int asap.

IP option doesn't work

I'll excuse in advance, I'm not that advanced in Python, but it seems that the IP function (-i --ip) doesn't work as it fails.

I fixed mine (I think) changing the code on line 150:
new_token.append('ip={0}'.format(self._escape_early(ip)))
to
new_token.append('ip={0}'.format(self._escape_early(self.ip)))
in cms_edgeauth.py

Available code for PHP?

Hi,

I have an old copy of Akamai EdgeAuth Token 2.0 implementation for PHP.

Can you publish on github?

Thanks!

license/copyright

Want to make sure I understand the terms of using this code.
In the readme it's stated that "(This is Akamai unofficial code)" but later under License section there's: "Copyright 2017 Akamai Technologies, Inc. All rights reserved."

Which is true? :)

EdgeAuth-Token-Python is Akamai Edge Authorization Token in the HTTP Cookie, Query String, and Header for a client.
You can configure it in the Property Manager at https://control.akamai.com.
It's a behavior which is Auth Token 2.0 Verification.

EdgeAuth-Token-Python supports Python 2.6

--- non-ascii byte 226 found here ---



--- non-ascii byte 128 found here ---



--- non-ascii byte 147 found here ---

2.7 & 3.3

--- non-ascii byte 226 found here ---



--- non-ascii byte 128 found here ---



--- non-ascii byte 147 found here ---

3.6 and runs great on PyPy.

Installation
------------

To install Akamai Edge Authorization Token for Python:

.. code-block:: bash

    $ pip install akamai-edgeauth


Example
-------

.. code-block:: python

    from akamai.edgeauth import EdgeAuth, EdgeAuthError
    import requests # just for this example

    ET_HOSTNAME = 'edgeauth.akamaized.net'
    ET_ENCRYPTION_KEY = 'YourEncryptionKey'
    DEFAULT_WINDOW_SECONDS = 500 # seconds


* ET_ENCRYPTION_KEY must be hexadecimal digit string with even-length.
* Don't expose ET_ENCRYPTION_KEY on the public repository.


**URL parameter option**

.. code-block:: python

    # 1) Cookie
    et = EdgeAuth(**{'key': ET_ENCRYPTION_KEY,
                      'window_seconds': DEFAULT_WINDOW_SECONDS})
    token = et.generate_url_token("/akamai/edgeauth")
    url = "http://{0}{1}".format(ET_HOSTNAME, "/akamai/edgeauth")
    response = requests.get(url, cookies={et.token_name: token})
    print(response) # Maybe not 403

    # 2) Query string
    token = et.generate_url_token("/akamai/edgeauth")
    url = "http://{0}{1}?{2}={3}".format(ET_HOSTNAME, "/akamai/edgeauth", et.token_name, token)
    response = requests.get(url)
    print(response)

* 'Escape token input' option in the Property Manager corresponds to 'escape_early' in the code.
    | Escape token input (on) == escape_early (True)
    | Escape token input (off) == escape_early (False)
* In [Example 2] for Query String, it's only okay for 'Ignore query string' option (on).
* If you want to 'Ignore query string' option (off) using query string as your token, Please contact your Akamai representative.


**ACL(Access Control List) parameter option**

.. code-block:: python

    # 1) Header using *
    et = EdgeAuth(**{'key': ET_ENCRYPTION_KEY,
                      'window_seconds': DEFAULT_WINDOW_SECONDS})
    token = et.generate_acl_token("/akamai/edgeauth/list/*")
    url = "http://{0}{1}".format(ET_HOSTNAME, "/akamai/edgeauth/list/something")
    response = requests.get(url, headers={et.token_name: token})
    print(response)

    # 2) Cookie Delimited by '!'
    acl_path = ["/akamai/edgeauth", "/akamai/edgeauth/list/*"]
    token = et.generate_acl_token(acl_path)
    # url = "http://{0}{1}".format(ET_HOSTNAME, "/akamai/edgeauth")
    url = "http://{0}{1}".format(ET_HOSTNAME, "/akamai/edgeauth/list/something2")
    response = requests.get(url, cookies={et.token_name: token})
    print(response)

* ACL can use the wildcard(\*, ?) in the path.
* Don't use '!' in your path because it's ACL Delimiter.
* Use 'escape_early=False' as default setting but it doesn't matter turning on/off 'Escape token input' option in the Property Manager


Usage
-----
**EdgeAuth Class**

.. code-block:: python

    class EdgeAuth(token_type=None, token_name='__token__', key=None, algorithm='sha256',
                   salt=None, ip=None, payload=None, session_id=None,
                   start_time=None, end_time=None, window_seconds=None,
                   field_delimiter='~', acl_delimiter='!', escape_early=False, verbose=False)

====================  ===================================================================================================
 Parameter             Description
====================  ===================================================================================================
 token_type            Select a preset. (Not Supported Yet)
 token_name            Parameter name for the new token. [Default: '__token__']
 key                   Secret required to generate the token. It must be hexadecimal digit string with even-length.
 algorithm             Algorithm to use to generate the token. ('sha1', 'sha256', or 'md5') [Default: 'sha256']
 salt                  Additional data validated by the token but NOT included in the token body. (It will be deprecated)
 ip                    IP Address to restrict this token to. (Troublesome in many cases (roaming, NAT, etc) so not often used)

 session_id            The session identifier for single use tokens or other advanced cases.
 start_time            What is the start time? (Use string 'now' for the current time)
 end_time              When does this token expire? end_time overrides window_seconds
 window_seconds        How long is this token valid for?
 field_delimiter       Character used to delimit token body fields. [Default: ~]
 acl_delimiter         Character used to delimit acl. [ Default: ! ]
 escape_early          Causes strings to be 'url' encoded before being used.

====================  ===================================================================================================

**EdgeAuth's Method**

.. code-block:: python

    def generate_url_token(url)

Test
----
"/test" directory is only for the internal test.


Others
------
If you use the **Segmented Media Protection** behavior in AMD(Adaptive Media Delivery) Product, **token_name** should be '**hdnts**'.
