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)
 payload               Additional text added to the calculated digest.
 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.
 verbose               Print all parameters.
====================  ===================================================================================================

**EdgeAuth's Method**

.. code-block:: python

    def generate_url_token(url)
    def generate_acl_token(acl)

    # Returns the authorization token string.

+-----------+--------------------------------------------------------------------------------------------------------+
| acl       | Access Control List can use the wildcard(\*, ?). It can be String (single path) or Array (multi paths) |
+-----------+--------------------------------------------------------------------------------------------------------+


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**'.
