Akamai Edge Authorization Token for Property Manager Behavior

Project description

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 It’s a behavior which is Auth Token 2.0 Verification.

EdgeAuth-Token-Python supports Python 2.6–2.7 & 3.3–3.6 and runs great on PyPy.


To install Akamai Edge Authorization Token for Python:

$ pip install akamai-edgeauth


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

ET_ENCRYPTION_KEY = 'YourEncryptionKey'
DURATION = 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

# 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)
  • ‘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

# 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})

# 2) Cookie Delimited by '!'
acl_path = ["/akamai/edgeauth", "/akamai/edgeauth/list/*"]
token = at.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={at.token_name: token})
  • 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


EdgeAuth Class

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

def generate_url_token(url)
def generate_acl_token(acl)

# Returns the authorization token string.
Parameter Description
url Single URL path (String)
acl Access Control List can use the wildcard(*, ?). It can be String (single path) or Array (multi paths)


“/test” directory is only for the internal test.


If you use the Segmented Media Protection behavior in AMD(Adaptive Media Delivery) Product, token_name should be ‘hdnts’.


$ python -k YourEncryptionKey -w 5000 -u /hello/world -x

Use -h or –help option for the detail.
