Azure Storage Blobs Cryptography client library for Java

Azure Blob storage is Microsoft's object storage solution for the cloud. Blob storage is optimized for storing massive amounts of unstructured data. Unstructured data is data that does not adhere to a particular data model or definition, such as text or binary data. This package supports client side encryption for blob storage.

• Java Development Kit (JDK) with version 8 or above
  • Here are details about Java 8 client compatibility with Azure Certificate Authority.
• Azure Subscription
• Create Storage Account

Please include the azure-sdk-bom to your project to take dependency on GA version of the library. In the following snippet, replace the {bom_version_to_target} placeholder with the version number. To learn more about the BOM, see the AZURE SDK BOM README.

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.azure</groupId>
            <artifactId>azure-sdk-bom</artifactId>
            <version>{bom_version_to_target}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

and then include the direct dependency in the dependencies section without the version tag.

<dependencies>
  <dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-storage-blob-cryptography</artifactId>
  </dependency>
</dependencies>

If you want to take dependency on a particular version of the library that is not present in the BOM, add the direct dependency to your project as follows.

<dependency>
  <groupId>com.azure</groupId>
  <artifactId>azure-storage-blob-cryptography</artifactId>
  <version>12.30.1</version>
</dependency>

To create a Storage Account you can use the Azure Portal or Azure CLI.

az storage account create \
    --resource-group <resource-group-name> \
    --name <storage-account-name> \
    --location <location>

In order to interact with the Storage service (Blob, Queue, Message, MessageId, File) you'll need to create an instance of the Service Client class. To make this possible you'll need the Account SAS (shared access signature) string of Storage account. Learn more at SAS Token

• SAS Token

a. Use the Azure CLI snippet below to get the SAS token from the Storage Account.

az storage blob generate-sas \
    --account-name {Storage Account name} \
    --container-name {container name} \
    --name {blob name} \
    --permissions {permissions to grant} \
    --expiry {datetime to expire the SAS token} \
    --services {storage services the SAS allows} \
    --resource-types {resource types the SAS allows}

Example:

CONNECTION_STRING=<connection-string>

az storage blob generate-sas \
    --account-name MyStorageAccount \
    --container-name MyContainer \
    --name MyBlob \
    --permissions racdw \
    --expiry 2020-06-15

b. Alternatively, get the Account SAS Token from the Azure Portal.

1. Go to your Storage Account
2. Select Shared access signature from the menu on the left
3. Click on Generate SAS and connection string (after setup)

a. Use Account name and Account key. Account name is your Storage Account name.

1. Go to your Storage Account
2. Select Access keys from the menu on the left
3. Under key1/key2 copy the contents of the Key field

or

b. Use the connection string.

1. Go to your Storage Account
2. Select Access keys from the menu on the left
3. Under key1/key2 copy the contents of the Connection string field

Blob storage is designed for:

• Serving images or documents directly to a browser.
• Storing files for distributed access.
• Streaming video and audio.
• Writing to log files.
• Storing data for backup and restore, disaster recovery, and archiving.
• Storing data for analysis by an on-premises or Azure-hosted service.

Note: The usage of the EncryptedBlobClient is the same as the equivalent BlobClient, the only difference being client construction. Please refer to azure-storage-blob for common use cases of the BlobClient

The following sections provide several code snippets covering some of the most common Azure Storage Blob cryptography creation tasks, including:

• Create an EncryptedBlobClient from a BlobClient
• Create an EncryptedBlobClient
• Use a LocalKeyEncryptionKey
• Use a KeyVaultKey

Create an EncryptedBlobClient using a BlobClient. BlobClient construction is explained in the azure-storage-blob README.

EncryptedBlobClient client = new EncryptedBlobClientBuilder()
    .key(key, keyWrapAlgorithm)
    .keyResolver(keyResolver)
    .blobClient(blobClient)
    .buildEncryptedBlobClient();

Create a BlobServiceClient using a connection string.

EncryptedBlobClient client = new EncryptedBlobClientBuilder()
    .key(key, keyWrapAlgorithm)
    .keyResolver(keyResolver)
    .connectionString(connectionString)
    .containerName(containerName)
    .blobName(blobName)
    .buildEncryptedBlobClient();

JsonWebKey localKey = JsonWebKey.fromAes(new SecretKeySpec(keyBytes, secretKeyAlgorithm),
    Arrays.asList(KeyOperation.WRAP_KEY, KeyOperation.UNWRAP_KEY))
    .setId("my-id");
AsyncKeyEncryptionKey akek = new KeyEncryptionKeyClientBuilder()
    .buildAsyncKeyEncryptionKey(localKey).block();

EncryptedBlobClient client = new EncryptedBlobClientBuilder()
    .key(akek, keyWrapAlgorithm)
    .connectionString(connectionString)
    .containerName(containerName)
    .blobName(blobName)
    .buildEncryptedBlobClient();

KeyClient keyClient = new KeyClientBuilder()
    .vaultUrl(keyVaultUrl)
    .credential(tokenCredential)
    .buildClient();
KeyVaultKey rsaKey = keyClient.createRsaKey(new CreateRsaKeyOptions(keyName)
    .setExpiresOn(OffsetDateTime.now().plusYears(1))
    .setKeySize(2048));
AsyncKeyEncryptionKey akek = new KeyEncryptionKeyClientBuilder()
    .credential(tokenCredential)
    .buildAsyncKeyEncryptionKey(rsaKey.getId())
    .block();

EncryptedBlobClient client = new EncryptedBlobClientBuilder()
    .key(akek, keyWrapAlgorithm)
    .connectionString(connectionString)
    .containerName(containerName)
    .blobName(blobName)
    .buildEncryptedBlobClient();

When interacting with blobs using this Java client library, errors returned by the service correspond to the same HTTP status codes returned for REST API requests. For example, if you try to retrieve a container or blob that doesn't exist in your Storage Account, a 404 error is returned, indicating Not Found.

All client libraries by default use the Netty HTTP client. Adding the above dependency will automatically configure the client library to use the Netty HTTP client. Configuring or changing the HTTP client is detailed in the HTTP clients wiki.

All client libraries, by default, use the Tomcat-native Boring SSL library to enable native-level performance for SSL operations. The Boring SSL library is an uber jar containing native libraries for Linux / macOS / Windows, and provides better performance compared to the default SSL implementation within the JDK. For more information, including how to reduce the dependency size, refer to the performance tuning section of the wiki.
