Connect to Azure Key Vault using Quarkus - java

I want to connect to azure key vault using quarkus application. I have stored some secrets on azure key vault , need to connect to azure key vault (without exposing service principal secret) , retrieve the values of the secret configured in azue key vault and use that in my application. I am not getting how to achieve this. can someone help.

I never did something like that using Quarkus, but there a few ways:
1-
You'll need to authenticate and get an access token from Azure Active Directory. Then, you'll pass the token into the request to get the secret:
https://learn.microsoft.com/en-us/azure/key-vault/general/authentication-requests-and-responses
https://learn.microsoft.com/en-us/rest/api/keyvault/
2-
As another alternative, you can use an Azure Function + Key Vault Reference to get the secrets, then pass them to your Quarkus application. You can do it using Azure Functions Custom Handlers:
https://techcommunity.microsoft.com/t5/apps-on-azure/azure-functions-in-any-language-with-custom-handlers/ba-p/1942744
3-I'm not 100% sure, but I guess you can use regular java to retrieve the secrets in your quarkus app too:
https://learn.microsoft.com/en-us/azure/key-vault/secrets/quick-create-java

There are multiple ways to authenticate to an Azure Key Vault to choose from and not all of them need you to provide your service principal's secret. Just remember to make sure that you pass the selected Credential object to your Key Vault Secrets client when instantiating it a SecretClientBuilder:
SecretClient secretClient = new SecretClientBuilder()
.vaultUrl("<your-key-vault-url>")
.credential(new DefaultAzureCredentialBuilder().build()) // This is one of many types of credentials you can use
.buildClient();

Is there a way to set Environment Variables for Azure Key vault using some API within the source code (not through cli)?

I was trying to set following env variable. But I wanted to do so with api if possible. I couldn't find anything, just wanted to make sure if I can.
AZURE_CLIENT_ID - service principal's app id
AZURE_TENANT_ID - id of the principal's Azure Active Directory tenant
AZURE_CLIENT_SECRET - one of the service principal's client secrets
As mentioned by #Vineesh Vijayan, you can use the Azure key vault which lets you retrieve key-value pairs. After creating the key vault resource, you can add your environment variables by Adding secret to Key Vault. Make sure you add the dependencies in pom.xml.
And now you can retrieve the stored keys after Authenticating your key vault using the below line.
KeyVaultKey retrievedKey = keyClient.getKey(keyName);
In Case you trying to Get Secrets using rest API, you can use
GET {vaultBaseUrl}/secrets/{secret-name}/{secret-version}?api-version=7.3

How should I implement key rotation for my AWS credentials in prod environment?

I'm looking at the below link which explains how to use AWS API to send emails. How would the below example work in prod environment since AWS access key ID and AWS secret access key added to the credential file would expire after some time.
https://docs.aws.amazon.com/ses/latest/DeveloperGuide/send-using-sdk-java.html
I can see how AWS SES SMTP can be used to send emails since the credentials don't change can be saved in a file on a server but unsure how SES API in the above link can be used.
Store your AWS credentials in Secrets Manager and automate the key rotation using SNS + Lambda, from there you could send the newly updated keys to your application through an endpoint.
Use this guide from the AWS Documentation as a somewhat relevant source of what you're trying to accomplish:
https://docs.aws.amazon.com/prescriptive-guidance/latest/patterns/automatically-rotate-iam-user-access-keys.html

Embedding AWS IAM credentials in the code with the Java SDK

I am using the Java AWS IoT SDK, and i'm I'm stuck with a problem whereby I have to embed my AWS IAM access key and secret key credentials into my Java application code on my devices.
The credentials are just used initially to create the client in my code, then X.509 certificates are used after for the MQTT authentication and communication. .
I've heard of a way to avoid the need of embedding IAM credentials in the code by using AWSCredentialsProvider with tokens etc. However, I don't see any actual examples of how to achieve this without embedding credentials. Below is a snippet of my code showing how I create the client object using the credentials. Thanks.
String AWS_ACCESSKEY = "AKXXXXXXXXXXXXX"; // not real key
String AWS_SECRETKEY = "ABCXXXXXXXXXXXXXXXXXXXXXX"; // not real key
Regions AWS_REGION = Regions.US_EAST_2;
AWSIot client = AWSIotClientBuilder.standard().withCredentials(new AWSStaticCredentialsProvider(new
BasicAWSCredentials(AWS_ACCESSKEY, AWS_SECRETKEY))).withRegion(AWS_REGION).build();
You can pass this credentials to normal application.properties file.
You just need to do 2 things.
Create public class AwsCredentials with annotations #ConfigurationProperties and #Configuration.
Pass Your access and secret to application.properties file
You can read more in this tutorial : click
Next when You want to use this properties in builder You need to call it like this:
AWSIot client = AWSIotClientBuilder.standard()
.withCredentials(
new AWSStaticCredentialsProvider(
new BasicAWSCredentials(
this.awsCredentials.getAccessKey(),
this.awsCredentials.getSecretKey()
)
)
)
.withRegion(AWS_REGION)
.build();
PS. You can export region to properties too.
You can use temporary security credentials instead of actual access keys. Do check this link.
https://docs.aws.amazon.com/general/latest/gr/aws-access-keys-best-practices.html
To get credentials to access AWS IoT (or other services) you could get temporary security credentials from Cognito Identity Pool. You can find the simplest way and steps needed to do get credentials here.
Also consider that, to get idToken (JWT) from Cognito user pool and then access and secret token Cognito Identity pool, you need to use AWS Java SDK in your mobile or desktop application. You can find more information about AWS JAVA SDK here and some samples here, here, .

Azure Key Vault working in locally but getting 403 forbidden error in azure cloud

I am new to Azure. I want to use Azure KeyVault to store secrets like passwords. I have successfully created All steps which mentioned in Microsoft website. And also able to get secrets (passwords from KeyVault) in our local environment by using Springboot application.properties .
But getting 403 Access denied error when I tried the same in Azure Cloud. It is not generated in local tomcat server. Please suggest me to resolve this issue.
Expected password, but getting 403.
You might need to
Enable system-assigned managed identity on an existing VM
Grant your VM access to a Secret stored in a Key Vault
Use Springboot key vault dependencies to get the secret.
In PowerShell run these commands to verify if key vault has right access permissions.
Get-AzureRmKeyVault -VaultName check what objectIds you see
Get-AzureRmADServicePrincipal -ObjectId check if your service's service principle (from AAD) is listed there.
you can also check out this link which i think may help you.

How to retrieve temporary AWS credentials from Amazon using IAM role associated with the EC2 instance(in java)?

I created IAM role associated with the EC2 instance on AMAZON and as I understood from the amazon docs I can retrieve temp AWS credentials and do some stuff with that.I read that the EC2 metadata api(which is used internally by InstanceProfileCredentialsProvider) is only available for calls from within the instance, not from the outside world.
What this means? How can I get secure communication with AWS when develop app on local tomcat server?
You should use the The default provider chain and EC2 instance profiles. In your case, since you've already added the role to your instance, and considering you are using the Java SDK, you need to call:
InstanceProfileCredentialsProvider mInstanceProfileCredentialsProvider = new InstanceProfileCredentialsProvider();
AWSCredentials credentials = mInstanceProfileCredentialsProvider.getCredentials();
Or, if you are using a specific service, such as AWS S3, you can directly call:
AmazonS3 s3Client = new AmazonS3Client(new DefaultAWSCredentialsProviderChain());
For more information: http://docs.aws.amazon.com/java-sdk/latest/developer-guide/java-dg-roles.html
And just a reminder: you should NEVER leave your Access Key and Key Secret in your code.
It appears that your situation is:
You have an application running on a computer that is not an Amazon EC2 instance
You wish to give that application the ability to make API calls to AWS services
In this situation, it is not appropriate to use an IAM role.
Instead, you will need to provide your application with a set of valid AWS credentials (Access Key + Secret Key). This can be done by creating an IAM User, copying the credentials provided and placing them in your application's configuration.
When making an API call from an application that uses an AWS SDK, the SDK will automatically look in various location for valid credentials. In the case of Java, the DefaultAWSCredentialsProviderChain that looks for credentials in this order:
Environment Variables - AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY (RECOMMENDED since they are recognized by all the AWS SDKs and CLI except for .NET), or AWS_ACCESS_KEY and AWS_SECRET_KEY (only recognized by Java SDK)
Java System Properties - aws.accessKeyId and aws.secretKey
Credential profiles file at the default location (~/.aws/credentials) shared by all AWS SDKs and the AWS CLI
Credentials delivered through the Amazon EC2 container service if AWS_CONTAINER_CREDENTIALS_RELATIVE_URI" environment variable is set and security manager has permission to access the variable,
Instance profile credentials delivered through the Amazon EC2 metadata service
Therefore, store the credentials in one of the first three options.
