Class KeyAsyncClient

java.lang.Object
com.azure.security.keyvault.keys.KeyAsyncClient
public final class KeyAsyncClient extends Object
The KeyAsyncClient provides asynchronous methods to manage keys in the Azure Key Vault. The client supports creating, retrieving, updating, deleting, purging, backing up, restoring, listing, releasing and rotating the keys. The client also supports listing deleted keys for a soft-delete enabled key vault.

Getting Started

In order to interact with the Azure Key Vault service, you will need to create an instance of the KeyAsyncClient class, a vault url and a credential object.

The examples shown in this document use a credential object named DefaultAzureCredential for authentication, which is appropriate for most scenarios, including local development and production environments. Additionally, we recommend using a managed identity for authentication in production environments. You can find more information on different ways of authenticating and their corresponding credential types in the Azure Identity documentation".

Sample: Construct Asynchronous Key Client

The following code sample demonstrates the creation of a KeyAsyncClient, using the KeyClientBuilder to configure it.

KeyAsyncClient keyAsyncClient = new KeyClientBuilder()
    .vaultUrl("<your-key-vault-url>")
    .credential(new DefaultAzureCredentialBuilder().build())
    .buildAsyncClient();

Create a Cryptographic Key

The KeyAsyncClient can be used to create a key in the key vault.

Code Sample:

The following code sample demonstrates how to asynchronously create a cryptographic key in the key vault, using the createKey(String, KeyType) API.

keyAsyncClient.createKey("keyName", KeyType.EC)
    .contextWrite(Context.of("key1", "value1", "key2", "value2"))
    .subscribe(key ->
        System.out.printf("Created key with name: %s and id: %s %n", key.getName(),
            key.getId()));

Note: For the synchronous sample, refer to KeyClient.


Get a Cryptographic Key

The KeyAsyncClient can be used to retrieve a key from the key vault.

Code Sample:

The following code sample demonstrates how to asynchronously retrieve a key from the key vault, using the getKey(String) API.

keyAsyncClient.getKey("keyName")
    .contextWrite(Context.of("key1", "value1", "key2", "value2"))
    .subscribe(key ->
        System.out.printf("Created key with name: %s and: id %s%n", key.getName(),
            key.getId()));

Note: For the synchronous sample, refer to KeyClient.


Delete a Cryptographic Key

The KeyAsyncClient can be used to delete a key from the key vault.

Code Sample:

The following code sample demonstrates how to asynchronously delete a key from the key vault, using the beginDeleteKey(String) API.

keyAsyncClient.beginDeleteKey("keyName")
    .subscribe(pollResponse -> {
        System.out.printf("Deletion status: %s%n", pollResponse.getStatus());
        System.out.printf("Key name: %s%n", pollResponse.getValue().getName());
        System.out.printf("Key delete date: %s%n", pollResponse.getValue().getDeletedOn());
    });

Note: For the synchronous sample, refer to KeyClient.

  • Method Details

    • getVaultUrl

      public String getVaultUrl()
      Get the vault endpoint url to which service requests are sent to.
      Returns:
      The vault endpoint url

    • getCryptographyAsyncClient

      public CryptographyAsyncClient getCryptographyAsyncClient(String keyName)
      Creates a CryptographyAsyncClient for the latest version of a given key.

      To ensure correct behavior when performing operations such as Decrypt, Unwrap and Verify, it is recommended to use a CryptographyAsyncClient created for the specific key version that was used for the corresponding inverse operation: Encrypt, Wrap, or Sign, respectively.

      You can provide a key version either via getCryptographyAsyncClient(String, String) or by ensuring it is included in the keyIdentifier passed to CryptographyClientBuilder.keyIdentifier(String) before building a client.

      Parameters:
      keyName - The name of the key.
      Returns:
      An instance of CryptographyAsyncClient associated with the latest version of a key with the provided name.
      Throws:
      IllegalArgumentException - If keyName is null or empty.

    • getCryptographyAsyncClient

      public CryptographyAsyncClient getCryptographyAsyncClient(String keyName, String keyVersion)
      Creates a CryptographyAsyncClient for a given key version.
      Parameters:
      keyName - The name of the key.
      keyVersion - The key version.
      Returns:
      An instance of CryptographyAsyncClient associated with a key with the provided name and version. If keyVersion is null or empty, the client will use the latest version of the key.
      Throws:
      IllegalArgumentException - If keyName is null or empty.

The backup operation may be used to export, in protected form, any key type from Azure Key Vault. Individual versions of a key cannot be backed up. Backup/Restore can be performed within geographical boundaries only; meaning that a backup from one geographical area cannot be restored to another geographical area. For example, a backup from the US geographical area cannot be restored in an EU geographical area. This operation requires the key/backup permission.

    • releaseKey

      public Mono<ReleaseKeyResult> releaseKey(String name, String version, String targetAttestationToken)
      Releases a key.

      The key must be exportable. This operation requires the 'keys/release' permission.

      Code Samples

      Releases a key. Subscribes to the call asynchronously and prints out the signed object that contains the released key when a response has been received.

      String myKeyVersion = "<key-version>";
String myTargetAttestationToken = "someAttestationToken";

keyAsyncClient.releaseKey("keyName", myKeyVersion, myTargetAttestationToken)
    .subscribe(releaseKeyResult ->
        System.out.printf("Signed object containing released key: %s%n", releaseKeyResult.getValue()));
      Parameters:
      name - The name of the key to release.
      version - The version of the key to retrieve. If this is empty or null, this call is equivalent to calling releaseKey(String, String), with the latest key version being released.
      targetAttestationToken - The attestation assertion for the target of the key release.
      Returns:
      A Mono containing the ReleaseKeyResult containing the released key.
      Throws:
      IllegalArgumentException - If name or targetAttestationToken are null or empty.
