Package com.azure.security.keyvault.keys

Class KeyClient

  • public final class KeyClient
extends Object
    The KeyClient provides synchronous 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 Azure Key Vault.

    Samples to construct the sync client

     KeyClient keyClient = new KeyClientBuilder()
     .vaultUrl("https://myvault.azure.net/")
     .credential(new DefaultAzureCredentialBuilder().build())
     .buildClient();
    See Also:
    KeyClientBuilder, PagedIterable

      • backupKey

        public byte[] backupKey​(String name)
        Requests a backup of the specified key be downloaded to the client. The key backup operation exports a key from Azure Key Vault in a protected form. Note that this operation does not return key material in a form that can be used outside the Azure Key Vault system, the returned key material is either protected to a Azure Key Vault HSM or to Azure Key Vault itself.

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.

        Lists the deleted keys in the key vault and for each deleted key prints out its recovery id.

         for (DeletedKey deletedKey : keyClient.listDeletedKeys(new Context("key1", "value1"))) {
     System.out.printf("Deleted key's recovery id:%s%n", deletedKey.getRecoveryId());
 }

        Code Samples to iterate over deleted keys by page

        Iterates over the deleted keys by page in the key vault and for each deleted key prints out its recovery id.

         keyClient.listDeletedKeys().iterableByPage().forEach(pagedResponse -> {
     System.out.printf("Got response details. Url: %s. Status code: %d.%n",
