I am working my first Azure function with http trigger. code are stored in TFS, our release team will deploy it use octopus.
my question is in which situation, authorization key of azure function will change?
remove function app? delete function? any other case?
Thanks,
Wes
my question is in which situation, authorization key of azure function will change? remove function app? delete function? any other case?
If you metioned authorization key is authorization code for http trigger. There are 2 types of keys (API Keys and Master key) for the http tigger function.
API Keys:
Function App Level keys means that all of specific function are the same for the current app. (Unless delete the function app, the key will changed/not exist)
Function level keys apply to the specific functions(Delete the specific functions, it will change)
Host: Also commonly referred to as Function App Level keys. Keys defined at this level apply to the entire Function App. You have the ability to define Function Keys at this level, and they would allow clients to authenticate against any function. This is also where your Master Key is defined.
Function: Function level keys apply to the specific functions they're defined under, restricting its use for authentication to that function only.
Master Key:
The master key provides administrative access to the runtime APIs. You should exercise care if you choose to use the Admin authorization level for your functions as we do not recommend redistributing the master key.
We also could use the Rest API to change the key. For more information about Http trigger function, please refer to this document.

I'm new to azure functions. So I have build a normal http trigger which takes 2 parameters as input. So using those parameters I'm pulling data from gen2 locations and showing it at the response side.
Currently I'm using function keys (created one for my testing purpose) and using the same.
So the Request which I'm passing looks something like this:-
https://(APP-NAME).azurewebsites.net/(RESOURCE-PATH)?param1=¶m2=,code=(Generated by function key)
Till this point everything is working well. Now I'm sharing this request API to set of people.
The response API is data which they can see. Now I'm trying to make the code dynamic (like the existing one should expire after a certain time and I should be able to pick new function key from the same function key name I created)
Is is possible to generate our own function keys (using some random key generator) from the back end and keep updating the values after a particular time interval
Please feel free to provide more suggestions.
Azure has provided an api for the function key management in azure
function. This api will allow you to create, delete and update the
function keys. It is available at runtime when your app is deployed
in the azure.
According to this documentation you can make the required changes to the function keys, also you need to pass Bearer Token credentials with you get/post requests as you must be authorized to be able to view or make changes to the function keys.
Since you want to change the function key after a particular interval of time, you can use a time trigger which will change the function key (after a particular interval of time) using the above api.
To generate a key use any random string generator provided in the
programming language of your choice . You can then store the new
generated function key in a blob storage for further use.

Timer trigger for Azure Functions
I basically want to achieve what is described under this link and I did stuck on the 'Get the system key' step. It does work for Azure Function without custom domain:
http://{functionappname}.azurewebsites.net/admin/host/systemkeys/eventgridextensionconfig_extension?code={masterkey}
but for any Azure Functions with custom domain it doesn't work. Response is not in expected format, it's just a static web site without the system key. Is there a way to get this key? I assume it might not be supported for such case.
From your description, you are talking about the function app on azure.
Function key is just a valication method to let you hit the endpoint of the trigger. Custom domain or use original domain both can use function key.
Go to this place to get the key:
trigger tier key:
function app tier key:
You can even add your custom key.
Let me know whether this can answer your question.
I'm looking to get at an Azure function app's list of operational endpoints for each function, in particular the secret code that needs to be passed in to invoke the function.
I've tried lots of current answers in SO but all only seem to work with Function App's which use Files as the secret storage type.
We have a requirement to use Blob storage which is also the default in V2 function apps.
What I'm really after is the code piece that comes after the function name when it's retrieved from the Azure portal, I can manufacture all the other pieces before that myself.
For example https://mytestfunapp-onazure-apidev03.azurewebsites.net/api/AcceptQuote?code=XYZABCYkVeEj8zkabgSUTRsCm7za4jj2OLIQWnbvFRZ6ZIiiB3RNFg==
I can see where the secrets are stored in Azure Blob Storage as we need to configure that anyway when we create all the resources in our scripts.
What I'm really look for is how to decrypt the secret stored in the file. I don't care what programming language or script the solution may be written in, I'll work with it, or convert it to another language that we can use.
Here's a snippet of what the stored secret looks like in Blob storage, it's just a JSON file.
I'm wondering if anyone out there has some experience with this issue and may be able to help me out.
For now it's not supported to get the true key value programmatically. you could just view your key or create new key in the portal. You could find the description here: Obtaining keys.
If your function is a WebHook, when using a key other than the default you must also specify the clientId as a query param (the client ID is the name of your new key):
https://<yourapp>.azurewebsites.net/api/<funcname>?clientid=<your key name>
More information refer to this wiki doc: WebHooks.
The Azure Function documentation is clear on using Host and/or Function keys to provide "api key" authorization. However, I can't find anything that indicates if there is a limit on how many keys can be created on a particular function or function app.
I would like to share a unique key with each tenant in a multi-tenant application so I can update or revoke them on a per-tenant basis. However, this approach will only work if I am able to generate hundreds (or potentially thousands) of keys.
Can anyone confirm any known limits on the number of keys that can be generated on a function app?
There aren't any strict limits imposed by the runtime, but we can't make any guarantees that this would be performant at scale.
I want to make an option such that I can issue 3rd part developers access to my data and to do so, similar to the following: https://docs.sharedcount.com/, I want to create a system wherein those developers are provided an API key for which the consumption count can be monitored
Came through Waterlock but does not look like it has this feature: http://waterlock.ninja/
Curious, what would be the best approach to implement API keywords for a Sail.js app?
Sails makes this incredibly easy by use of policies. When a user signs up, assign them an API key, and then create a policy that checks the params for a valid API key -- i.e. req.param('APIKey') -- and deny access if one is not found.
