| <p>Ozone TDE setup process and usage are very similar to HDFS TDE. |
| The major difference is that Ozone TDE is enabled at Ozone bucket level |
| when a bucket is created.</p> |
| <h3 id="setting-up-the-key-management-server">Setting up the Key Management Server</h3> |
| <p>To use TDE, admin must setup a Key Management Server and provide that URI to |
| Ozone/HDFS. Since Ozone and HDFS can use the same Key Management Server, this |
| configuration can be provided via <em>hdfs-site.xml</em>.</p> |

| <h3 id="using-transparent-data-encryption">Using Transparent Data Encryption</h3> |
| <p>If this is already configured for your cluster, then you can simply proceed |
| to create the encryption key and enable encrypted buckets.</p> |
| <p>To create an encrypted bucket, client need to:</p> |
| <ul> |
| <li>Create a bucket encryption key with hadoop key CLI, which is similar to |
| how you would use HDFS encryption zones.</li> |
| </ul> |
| <div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-bash" data-lang="bash">hadoop key create encKey |
| </code></pre></div><p>The above command creates an encryption key for the bucket you want to protect. |
| Once the key is created, you can tell Ozone to use that key when you are |
| reading and writing data into a bucket.</p> |
| <ul> |
| <li>Assign the encryption key to a bucket.</li> |
| </ul> |
| <div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-bash" data-lang="bash">ozone sh bucket create -k encKey /vol/encryptedBucket |
| </code></pre></div><p>After this command, all data written to the <em>encryptedBucket</em> will be encrypted |
| via the encKey and while reading the clients will talk to Key Management |
| Server and read the key and decrypt it. In other words, the data stored |
| inside Ozone is always encrypted. The fact that data is encrypted at rest |
| will be completely transparent to the clients and end users.</p> |
