Oauth token encryption and hash - encryption

Once oauth token is generated in api, in the response
We need to encrypt oauth token, then salt with timestamp and hash it
Using client credentials, the client is hitting apigee. but in response how to encrypt oauth token, then salt with timestamp and hash it?
curl https://{org}-test.apigee.net/oauth/client_credential/
accesstoken?grant_type=client_credentials -X POST -d
'client_id={consumer_key}&client_secret={consumer_secret}'
the response is as follows
{
"issued_at" : "1382703699776",
"application_name" : "8586c7b7-2936-4779-b7a6-97014e436d7d",
"scope" : "READ",
"status" : "approved",
"api_product_list" : "[PremiumWeatherAPI]",
"expires_in" : "3599",
"developer.email" : "tesla#weathersample.com",
"organization_id" : "0",
"client_id" : "SJOaCEGohSu3vpNswMs5YdBlc2GOAh1J",
"access_token" : "UAj2yiGAcMZGxfN2DhcUbl9v8WsR",
"organization_name" : "myorg",
"refresh_token_expires_in" : "0",
"refresh_count" : "0"
}
in response I need to encrypt the oauth access token and salt with timestamp and then hash it.
How to do that

Here is an approach that you can use:
Right after the Generate access token policy you would be able to access oauthv2accesstoken.{policy_name}.access_token variable. Use an assign message policy to assign this value to a variable.
Next, for calculating the hash you need to use a java, python or a javascript policy in the response part of the flow. This link has a sample JavaScript for sha256.

python fastapi redirect and authenticate

I'm trying to authenticate the user after visiting the registration link
(link example: http://127.0.0.1:8000/confirm-email?token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9F)
My code:
#app.get("/confirm-email", status_code=200, )
def confirm_email(
token: str = fastapi.Query(..., min_length=64, max_length=256,
db: Session = fastapi.Depends(database.get_db)):
if user := crud.read_user_by(db, column='current_token', value=token):
if user.created_datetime + timedelta(minutes=30) > datetime.now(): # TODO change minutes to days
return fastapi.responses.RedirectResponse(
url="http://127.0.0.1:8000/users/me",
headers={"access_token": token, "token_type": "bearer"})
else:
raise fastapi.HTTPException(
status_code=fastapi.status.HTTP_410_GONE,
detail="Confirmation link is expired")
else:
raise fastapi.HTTPException(
status_code=fastapi.status.HTTP_401_UNAUTHORIZED,
detail="Wrong token")
#app.get("/users/me")
def read_users_me(token: str = fastapi.Depends(oauth2_scheme),
db: Session = fastapi.Depends(database.get_db)):
try:
return services.get_user_by_token(db=db, token=token)
except Exception as e:
raise fastapi.HTTPException(
status_code=fastapi.status.HTTP_401_UNAUTHORIZED,
detail="Could not validate credentials",
headers={"WWW-Authenticate": "Bearer"},
)
But every time I'm failing when trying to use /users/me endpoint (getting 401 error, UNAUTHORIZED).
Maybe I put the token in the wrong place or using wrong headers?
If using OAuth 2.0 and wanting to set the access_token in a request, tipically, it goes into the Authorization header like the example in the RFC: Authorization: Bearer mF_9.B5f-4.1JqM - in the example, mF_9.B5f-4.1JqM would be the value of the token.
It seems to me that you are accessing the users/me endpoint with the headers access_token: [token value] and token_type: "bearer". Instead, I believe the following header should be set: Authorization: Bearer [token value]
After a little researching, I figured out that redirection by specification can't have authorization headers (browser/client will just ignore it mainly). So even if headers are correct - it's nonsense. One possible solution to use URL.

Firebase Realtime Database returns 401 when trying to authenticate?

I am using REST API in my app to communicate with a Firebase RTDB, and trying to use a Google Access Token to authenticate my requests.
My issue is that with even the most permissive Rules on the database, I get HTTP error 401 in response to queries that try to authenticate.
For example, say I try to put some data in my database with the following command, I get 401 in return (all the values within < > are placeholders):
curl -XPUT -d '{ "UserID" : "<GOOGLE_UID>", "UserName" : "Clicksurfer", "CompletionMoves" : 8, "CompletionTime" : 16.21979 }' https://<FIREBASE_URL>.firebaseio.com/Level2/<GOOGLE_UID>.json/?access_token=<GOOGLE_ACCESS_TOKEN>
401
The strangest part is, when I abandon the use of access token altogether the query works:
curl -XPUT -d '{ "UserID" : "<GOOGLE_UID>", "UserName" : "Clicksurfer", "CompletionMoves" : 8, "CompletionTime" : 16.21979 }' https://<FIREBASE_URL>.firebaseio.com/Level2/<GOOGLE_UID>.json
200
As I said, I am currently using the most permissive rules for debugging:
{
"rules": {
".read": true,
".write": true
}
}
Any idea what might be causing this? Thanks in advance
EDIT:
I use the Google Play Games plugin for Unity in my project, among other things to get the AuthCode.
In order to do this, I needed to do a couple of things:
When building the config for Google Play Games during startup, I made sure to call the RequestServerAuthCode(false) method
Have the user login after Google Play Games sets up
Make sure that the relevant ClientID was supplied to Unity (in this case, it is a web client that has auth permissions on my Firebase rtdb).
This all looks like this:
public class GPGSAuthentication : MonoBehaviour
{
public static PlayGamesPlatform platform;
void Start()
{
if (platform == null)
{
PlayGamesClientConfiguration config = new PlayGamesClientConfiguration.Builder().RequestServerAuthCode(false).Build();
PlayGamesPlatform.InitializeInstance(config);
PlayGamesPlatform.DebugLogEnabled = true;
platform = PlayGamesPlatform.Activate();
}
Social.Active.localUser.Authenticate(success =>
{
if (success)
{
Debug.Log("GSPS - Logged in successfully");
}
else
{
Debug.Log("GSPS - Falied to login");
}
});
}
}
Now that we've done this, we can call PlayGamesPlatform.Instance.GetServerAuthCode() in order to get the AuthCode.
I traded in my AuthCode for an Access Token by sending a POST request to https://www.googleapis.com/oauth2/v4/token. In my query, I supply 4 fields:
client_id, which has the ID of the previously used client (where we got the AuthCode from).
client_secret, which has the correlating secret.
grant_type, which is always with the value "authorization_code"
code, which has the value of the AuthCode we got.
In response, I get a 200 response with 4 parameters:
access_token, the token I (fail to) use when authenticating against my Firebase rtdb.
token_type, the type of the aforementioned token.
expires_in, the amount of time before the token expires (I presume in seconds unit)
refresh_token, a token which can be used in order to get a new access_token without having to keep the Google user connected.
I then supply this access_token value to the queries I send to my DB, and promptly get the 401 error.

Microsoft Graph 'Unable to read JSON request payload' error when inviting users to Azure AD in Python with Requests

I'm trying to automate inviting users to an Azure AD using the MS Graph API but get an 'Unable to read JSON request payload' error.
I'm pulling data from a ticketing system, retrieving the current AAD users and diff-ing both. Then I'll be pushing the new ones into the AAD and updating them to include them in an Attendees AD Security group.
I created a Python Azure Function that calls the Graph API with Requests :
def insert_users(users_emails):
logging.info('Inserting new users in AAD')
token = generate_auth_token()
users_emails = users_emails[:2]
added_attendees = []
for email in users_emails:
req_body = {
"invitedUserEmailAddress" : email
, "inviteRedirectUrl" : "https://myapp.com"
}
body_length = sys.getsizeof(req_body)
req_headers = {
'Authorization' : 'Bearer {0}'.format(token)
, 'Content-Type' : 'application/json; charset=utf-8'
, 'Content-Length' : str(body_length)
}
response = requests.post(
'https://graph.microsoft.com/v1.0/invitations'
, headers = req_headers
, data = req_body
)
response = response.json()
logging.info(response)
added_attendees.append(email)
return added_attendees
The Graph API sends back the following error message :
{'error':
{'code': 'BadRequest',
'message': 'Unable to read JSON request payload. Please ensure Content-Type header is set and payload is of valid JSON format.',
'innerError':
{'request-id': '4ff5332d-d280-4b0d-9e04-a7359ab0e2fb', 'date': '2020-05-27T14:51:18'}
}
}
I tried adding the charset to the Content-Type header but it won't work. I read someplace the Content-Length could be useful so I added it too, to no avail.
Tests run ok in Postman and I'm already performing a POST request against the Azure AD API to get an Access Token so the Requests JSON body is parsed fine then. I also tried using single or double quotes in the JSON payload but it didn't work either.
My take is something is misinterpreted by the Graph API but I can't figure out what.
Thanks forward for your help !
i found a solution. Instead of passing a data argument to the request.post method, I passed a json= argument
response = requests.post(
'https://graph.microsoft.com/v1.0/invitations'
, json={'invitedUserEmailAddress':email,'inviteRedirectUrl':'https://myapp.com'}
, headers = req_headers
)

FCM with Postman - The request was missing an Authentication Key (FCM Token)

//body its like this
{
"to":
"/topics/NEWS"
,
"data":{
"extra_information": "This is some extra information"
},
//notification that i need to give
"notification":{
"title": "ChitChat Group",
"text": "You may have new messages",
"click_action":"ChatActivity"
}
}
The 401 error pertains that your Authorization Key is invalid or incorrect.
When using Postman, add a key= prefix for the value of Authorization, like so:
key=AAA...
See below for a tutorial on Sending Downstream FCM Messages using Postman.
Also, for your notification message payload, text isn't one of the valid parameters, I think you were looking for message instead.
Sending Downstream Messages using Postman
To do this in Postman, you simply have to set the following:
Set request type to POST
In the Headers, set the following:
Content-Type = application/json
Authorization = < Your FCM Server Key > (See your Firebase Console's Cloud Messaging Tab)
Set the payload parameters in the Body (*in this example, we used the raw option, see screenshot (2)*)
Send the request to https://fcm.googleapis.com/fcm/send
Screenshots:
(1)
Note: Always keep your Server Key a secret. Only a portion of my key is visible here so it should be fine.
(2)
(3)
Notice that the request was a success with the message_id in the response.
Wrong:
Authorization:AIzaSyDDk77PRpvfhh......
Correct:
Authorization:key=AIzaSyDDk77PRpvfhh......
Full example:
https://fcm.googleapis.com/fcm/send
Content-Type:application/json
Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA
{ "data": {
"score": "5x1",
"time": "15:10"
},
"to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1..."
}
While the answers above are still correct, you may choose to use HTTP v1. This requires Bearer instead of key= and uses an Oauth2 access token instead of a server key string. To view HTTP v1 specifications, please refer to the link below:
https://firebase.google.com/docs/cloud-messaging/migrate-v1
I was also getting same error in PHP , solved with below header :
$header = array("authorization: key=" . $this->apiKey . "","content-type: application/json");

What is the parameter name for basic authentication in meteor's http.post API?

I'm using HTTP.post in meteor and I need to send basic authentication with only a username to an external service. Where does this go and what would that look like?
I am only using it on the server side so I know it should look like the below code, but I'm not sure where to put the username and what to call it.
I've tried this.
var resultSet = HTTP.post("https://billy.balancedpayments.com/v1/customers", {
params: {"processor_uri": "/customers/customerURI"},
authentication: {"MYKEYHERE":""}
});
And this.
var resultSet = HTTP.post("https://billy.balancedpayments.com/v1/customers", {
params: {"authentication": "MYKEYHERE",
"processor_uri": "/customers/customerURI"}
});
And this.
var resultSet = HTTP.post("https://billy.balancedpayments.com/v1/customers", {
params: {"processor_uri": "/customers/customerURI"
},
headers: {'Authorization': 'MYKEYHERE'}
});
I get this error each time.
Error: failed [403] 403 Forbidden Access was denied to this resource.
Unauthorized: CustomerIndexView failed permission check
The plain auth : 'username:password' should do (from docs):
var resultSet = HTTP.post("https://billy.balancedpayments.com/v1/customers", {
params: {"processor_uri": "/customers/customerURI"},
auth: 'yourkey:'
});
As per the balanced payments documentation:
To authenticate with Balanced, you will need the API key secret provided from the dashboard. You have to use http basic access authentication. Your key has to be set as the username. A password is not required for simplicity.
So this means you leave the password blank, so its just your key followed by the colon :
Also you might want to consider using the balanced package for Meteor which does all the boilerplate for you.
