This regarding Azure vault. Please help me know how to retrieve data from azure vault using java.
I have tried most of the options available in the internet but have not received any descriptions or detail as to what is happening in the code.
I am new to coding hence it is a little difficult to understand .
UPDATE
I used the code mentioned in below reference but i am unable to write the same program for spring boot. I am how shold i convert this to restcontroller
Below are ref i used :How can i get secret from key vault?
Just follow the steps of my answer in How can i get secret from key vault to register an application and add access policy to it in Azure KeyVault.
Get my sample at AzureKeyVault
In my sample, I just create an utils class and then use it in controllers to access KeyVault. To, run the sample, you need to change the environment variables' values in application.properties to your own values.

Please help me to find out the documentation on how to use java MASL SDK to get access_token for a service principal.
I am looking to find the documentation or GIT links which can guide me how to use the MASL library including the code samples.
I have gone through this link but it does not help me much : https://learn.microsoft.com/en-us/azure/active-directory/develop/msal-authentication-flows
And, I am not expecting code samples to be shared here. I just want to find out where to find such data. I am struggling a lot when it comes to finding the right knowledge with respect to azure learning. What am I missing here? Is there any azure reference link available to find such information at a centralized place?
Note that, based on your requirement you can make use of Authorization code Flow if you want the user to sign-in and authenticate and if you want to access API using Application then make use of Client Credential Flow.
I tried to reproduce the same in my environment and got the results like below:
I created an Azure AD Application and added API permission:
For Client-Credential Flow, refer this GitHub blog by siddhijain.
Use the MASL java SDK to authenticate user in azure function developed in java.
Assuming that you want to authenticate user, you can make use of Authorization code Flow to generate access token.
I generated the Authorization code by using below endpoint:
https://login.microsoftonline.com/TenantID/oauth2/v2.0/authorize?
&client_id=ClientID
&response_type=code
&redirect_uri=RedirectUri
&response_mode=query
&scope=https://management.azure.com/user_impersonation
&state=12345
A sign-in screen will appear for authenticating the user:
To generate the access token, I used below parameters:
https://login.microsoftonline.com/TenantID/oauth2/v2.0/token
client_id:ClientID
client_secret:ClientSecret
scope:https://management.azure.com/user_impersonation
grant_type:authorization_code
redirect_uri:RedirectUri
code:code
I am able to call the Function by using above generated access token:
To implement the above in MSAL Java library, refer the below GitHub Blogs:
Microsoft-authentication-library-for-js/msal-node/auth-code AzureAD by derisen
Microsoft-authentication-library-for-js/samples/msal-node AzureAD by rgins16
There are lots of questions and articles on how to do this with .NET, but how/is it possible to easily authenticate for local development through Azure AD shared secret credential using Java (Spring Boot specifically)?
For .NET, it is as easy as specifying the RunAs=CurrentUser property in the connection string to connect to the Azure Key Vault (per this article: https://learn.microsoft.com/en-us/azure/key-vault/service-to-service-authentication), connecting automatically (assuming my account is listed in the access policy for the key vault I want to access). Ideally, I would not want to use a thousand Java dependencies to do this, I could manually obtain a token to authenticate, but it would be nice to save developers the hassle of having to manually obtain a token from Azure every time we wanted to test things for local development.
Thanks!
Here is an example os using MSICredentials Read Azure key vault secret through MSI in Java
Just try using the AzureCliCredentials instead https://azure.github.io/azure-sdk-for-java/com/microsoft/azure/credentials/AzureCliCredentials.html
I have some secret api keys for my server and i have to use in my project. But i am not feeling safe to keep in properties file or any physical location in server. Can any one tell me what are possible ways to keep it secret and use wherever it's require in application.
If you are really considered about the passwords you've got, the best way is using HSM (Hardware security module). This way you will be assured that keeping your private key in a secure place is not part of your consideration anymore.
If that is expensive, then you can think of storing your private key in JKS or PKCS12 and choose a strong password.
Generally you are looking for a vault. In PKI you can have a vault to store your secret in it. there are couple of ways I can think of. One of them is HSM as I described above and the other one is following:
For storing your password you need to salt it or store it in another server w/ salt and whenever you need the password, it's better to have a secure connection between your real server and password only stored server to request the password.
Also you can take a look at this project from Hashicorp
https://github.com/hashicorp/vault
There are many options here depending on your actual security requirements.
You've mentioned java and spring boot, so I'll mainly specify solutions related to this technology stack.
Since you're already using Spring Boot, consider spring-cloud-config server.
It has some interesting "encryption" features:
Step 1
Create a Key (public/private pair or shared depending on your requirements)
Specify it when starting the config server (via -- or env variable):
encrypt.key=ABC123ABC123ABC123
Step 2
Encode value of the password by calling a rest request of this server (you do it once)
curl localhost:8888/encrypt -d mysecretdbpassword
>>AZXCASDAZXC341234ZXCASDFedr453
Step 3
In application.properties specify that the value is "encrypted" with a special syntax
The file will be stored on a configuration server and not on the microservice. The
property will look like this
db.password={cipher}AZXCASDAZXC341234ZXCASDFedr453
The property will be kept encrypted in files but decrypted in memory. So the microservice will get a decrypted value.
The documentation is available here. This is by far the fastest way to implement the requirements. You can keep it in a dedicated microservice or embedded into the already-existing application.
In addition, it allows integration with JKS, so its possible to store passwords there.
Complementary/Alternatives
Spring cloud config is also integrated with Hashicorp Vault which can be a good solution for your situation on its own (even without spring boot cloud config).
Yet Another possible solution that comes from Spring Universe is called Spring Vault
Its intended for working with secrets.
I use onboardbase to hide secret i would recommend that they are few other out there to check like doppler
You can setup your application.properties as below
application.properties
secret.key1=${SECRET_KEY1}
secret.key2=${SECRET_KEY2}
While building the application we can pass it as an environment variable
mvn clean install -dSECRET_KEY1=123456 -dSECRET_KEY2=abcdef
We can pass the environment variables in docker as well by using -e SECRET_KEY1=123456
After reading several topics about this, I tried to put my API URL in gradle as BuildConfigField, but when I decompile it, I was able to see.
Is there any current way to hide it now?
Use a secret manager service as Hashicorp Vault or AWS Secret manager
From AWS Secret manager page:
The service enables you to easily rotate, manage, and retrieve database credentials, API keys, and other secrets throughout their lifecycle. Users and applications retrieve secrets with a call to Secrets Manager APIs, eliminating the need to hardcode sensitive information in plain text
I'm facing the same problem as you now and it looks to be the solution for my use case.
i want use azure Device Identities REST API to create devices identity :https://msdn.microsoft.com/en-us/library/azure/mt548489.aspx
but i don't know the syntaxe to set in header request ?
what is the key and how to generate value ?
here is the param :
Set the Authorization header to a SAS token created as specified in the service section of Using IoT Hub security tokens.
The Etag header is returned in all requests scoped to a single device identity, as per RFC7232 .
Thanks
As #DominicBetts said, you can refer to the referenced document to generate the SAS token by yourself.
As reference, there is not an existing sample code for Java, but I think you can try to refer to the offical sample for Python to knwo how to use the device identities REST API, please see the sample at https://azure.microsoft.com/en-us/documentation/samples/iot-hub-python-get-started/ and download the sample zip file to see the script service/deviceManager.py.
Meanwhile, you can also try to directly read the source code of IoTHub SDK for Java. For generating the SAS token, please see the code at https://github.com/Azure/azure-iot-sdks/blob/master/java/service/iothub-service-sdk/src/main/java/com/microsoft/azure/iot/service/auth/IotHubServiceSasToken.java.
Please take a look here: https://azure.microsoft.com/documentation/articles/iot-hub-sas-tokens/#using-security-tokens-from-service-components
This article explains how you can generate the security token you need - in particular the section "Using security tokens from service components".
