EDIT: for a very secure way of generating random number, you should use urandom: You can just generate keys of your desired length the python way: And then you can just call it with your desired length key = generatekey(40).
Azure Key Vault helps you protect secrets such as the API keys and database connection strings needed to access your applications, services, and IT resources.
If the API key that you need doesn't already exist, then create an API key in the Console by clicking Create credentials API key. You can restrict the key before using it in production by clicking Restrict key and selecting one of the Restrictions. To keep your API keys secure, follow the best practices for securely using API keys. To use your API key for Basic Authentication, it must be generated using Artifactory 4.4.3 or later. If generated on a previous version, you must regenerate your API key and use the new key as a password for basic authentication.
In this tutorial, you set up an Azure web application to read information from Azure Key Vault by using managed identities for Azure resources. You learn how to:
Before you go any further, make sure you understand the basic concepts about Key Vault.
Prerequisites
Use Azure Cloud Shell
Azure hosts Azure Cloud Shell, an interactive shell environment that you can use through your browser. You can use either Bash or PowerShell with Cloud Shell to work with Azure services. You can use the Cloud Shell preinstalled commands to run the code in this article without having to install anything on your local environment.
To start Azure Cloud Shell:
To run the code in this article in Azure Cloud Shell:
Understand Managed Service Identity
Azure Key Vault can store credentials securely so they aren't in your code. To retrieve them, you need to authenticate to Azure Key Vault. However, to authenticate to Key Vault, you need a credential. It's a classic bootstrap problem. Through Azure and Azure Active Directory (Azure AD), Managed Service Identity (MSI) provides a bootstrap identity that makes it simpler to get things started.
When you enable MSI for an Azure service like Virtual Machines, App Service, or Functions, Azure creates a service principal for the instance of the service in Azure AD. It injects the credentials for the service principal into the instance of the service.
Next, your code calls a local metadata service available on the Azure resource to get an access token. Your code uses the access token that it gets from the local MSI endpoint to authenticate to an Azure Key Vault service.
Sign in to Azure
To sign in to Azure by using the Azure CLI, enter:
Create a resource group
An Azure resource group is a logical container into which Azure resources are deployed and managed.
Create a resource group by using the
az group create command in the West US location with the following code. Replace YourResourceGroupName with a name of your choice.
You use this resource group throughout the tutorial.
Create a key vault
Next, you create a key vault in the resource group that you created in the previous step. Provide the following information:
At this point, your Azure account is the only one that's authorized to perform any operations on this new vault.
Add a secret to the key vault
We're adding a secret to help illustrate how this works. You might want to store a SQL connection string or any other information that needs to be both kept secure and available to your application.
Type the following commands to create a secret in the key vault called AppSecret. This secret will store the value MySecret.
Create a Linux virtual machine
Create a VM by using the
az vm create command.
The following example creates a VM named myVM and adds a user account named azureuser. The
--generate-ssh-keys parameter automatically generates an SSH key and puts it in the default key location (~/.ssh). To create a specific set of keys instead, use the --ssh-key-value option.
It takes a few minutes to create the VM and supporting resources. The following example output shows that the VM creation was successful:
Make a note of your own
publicIpAddress in the output from your VM. You'll use this address to access the VM in later steps.
Assign an identity to the VM
Create a system-assigned identity to the virtual machine by running the following command:
The output of the command is as follows.
Make a note of the
systemAssignedIdentity . You use it the next step.
Give the VM identity permission to Key Vault
Now you can give Key Vault permission to the identity you created. Run the following command:
Log in to the VM
Log in to the virtual machine by using a terminal.
Install Python library on the VM
Download and install the requests Python library to make HTTP GET calls.
![]() Create, edit, and run the sample Python app
Create a Python file called Sample.py.
Open Sample.py and edit it to contain the following code:
The preceding code performs a two-step process:
Run the following command. You should see the secret value.
In this tutorial, you learned how to use Azure Key Vault with a Python app running on a Linux virtual machine.
Clean up resources
Delete the resource group, virtual machine, and all related resources when you no longer need them. To do so, select the resource group for the VM and select Delete.
Delete the key vault by using the
az keyvault delete command:

Using the Shared Access Signature (at HTTP level)
Now that you know how to create Shared Access Signatures for any entities in Service Bus, you are ready to perform an HTTP POST:
Python Requests Api Key
Remember, this SAS key works for everything. You can create SAS for a queue, topic, subscription, Event Hub, or relay. If you use per-publisher identity for Event Hubs, you can append
/publishers/< publisherid> .

If you give a sender or client a SAS token, they don't have the key directly, and they cannot reverse the hash to obtain it. As such, you have control over what they can access, and for how long. An important thing to remember is that if you change the primary key in the policy, any Shared Access Signatures created from it is invalidated.
