 * <strong>Security Considerations:</strong>

 * <ul>
 * <li>Default Blowfish algorithm is suitable for general-purpose encryption</li>
 * <li>For high-security applications, consider using AES with GCM mode via {@link #setAlgorithm(String)} and {@link #setTransformation(String)}</li>
 * <li>Ensure keys are securely generated and stored</li>

The domains are securely verified and the certificates are generated automatically. This also allows automating the renewal of these certificates.

The idea is to automate the acquisition and renewal of these certificates so that you can have **secure HTTPS, for free, forever**.

 * Because they don't attempt canonical form, these classes are surprisingly difficult to use

### Experimental Features

* `kubeadm` (alpha) provides an easy way to securely bootstrap Kubernetes on Linux, see http://kubernetes.io/docs/kubeadm/ ([#33262](https://github.com/kubernetes/kubernetes/pull/33262), [@errordeveloper](https://github.com/errordeveloper))
* Alpha JWS Discovery API for locating an apiserver securely ([#32203](https://github.com/kubernetes/kubernetes/pull/32203), [@dgoodwin](https://github.com/dgoodwin))

/**
 * Java 5 annotation for describing service layer security attributes.
 *
 * <p>
 * The <code>Secured</code> annotation is used to define a list of security configuration
 * attributes for business methods.
 * <p>
 * For example:
 *
 * <pre>
 * &#064;Secured({ &quot;ROLE_USER&quot; })
 * public void create(Contact contact);
 *
 * &#064;Secured({ &quot;ROLE_USER&quot;, &quot;ROLE_ADMIN&quot; })
