| <FONT color="green">027</FONT> * <code>AuthenticationInfo</code> represents a Subject's (aka user's) stored account information relevant to the<a name="line.27"></a> |
| <FONT color="green">028</FONT> * authentication/log-in process only.<a name="line.28"></a> |
| <FONT color="green">029</FONT> * <p/><a name="line.29"></a> |
| <FONT color="green">030</FONT> * It is important to understand the difference between this interface and the<a name="line.30"></a> |
| <FONT color="green">031</FONT> * {@link AuthenticationToken AuthenticationToken} interface. <code>AuthenticationInfo</code> implementations<a name="line.31"></a> |
| <FONT color="green">032</FONT> * represent already-verified and stored account data, whereas an <code>AuthenticationToken</code> represents data<a name="line.32"></a> |
| <FONT color="green">033</FONT> * submitted for any given login attempt (which may or may not successfully match the verified and stored account<a name="line.33"></a> |
| <FONT color="green">034</FONT> * <code>AuthenticationInfo</code>).<a name="line.34"></a> |
| <FONT color="green">035</FONT> * <p/><a name="line.35"></a> |
| <FONT color="green">036</FONT> * Because the act of authentication (log-in) is orthogonal to authorization (access control), this interface is<a name="line.36"></a> |
| <FONT color="green">037</FONT> * intended to represent only the account data needed by Shiro during an authentication attempt. Shiro also<a name="line.37"></a> |
| <FONT color="green">038</FONT> * has a parallel {@link org.apache.shiro.authz.AuthorizationInfo AuthorizationInfo} interface for use during the<a name="line.38"></a> |
| <FONT color="green">039</FONT> * authorization process that references access control data such as roles and permissions.<a name="line.39"></a> |
| <FONT color="green">040</FONT> * <p/><a name="line.40"></a> |
| <FONT color="green">041</FONT> * But because many if not most {@link org.apache.shiro.realm.Realm Realm}s store both sets of data for a Subject, it might be<a name="line.41"></a> |
| <FONT color="green">042</FONT> * convenient for a <code>Realm</code> implementation to utilize an implementation of the {@link Account Account}<a name="line.42"></a> |
| <FONT color="green">043</FONT> * interface instead, which is a convenience interface that combines both <code>AuthenticationInfo</code> and<a name="line.43"></a> |
| <FONT color="green">044</FONT> * <code>AuthorizationInfo</code>. Whether you choose to implement these two interfaces separately or implement the one<a name="line.44"></a> |
| <FONT color="green">045</FONT> * <code>Account</code> interface for a given <code>Realm</code> is entirely based on your application's needs or your<a name="line.45"></a> |
| <FONT color="green">046</FONT> * preferences.<a name="line.46"></a> |
| <FONT color="green">047</FONT> * <p/><a name="line.47"></a> |
| <FONT color="green">048</FONT> * <p><b>Pleae note:</b> Since Shiro sometimes logs authentication operations, please ensure your AuthenticationInfo's<a name="line.48"></a> |
| <FONT color="green">049</FONT> * <code>toString()</code> implementation does <em>not</em> print out account credentials (password, etc), as these might be viewable to<a name="line.49"></a> |
| <FONT color="green">050</FONT> * someone reading your logs. This is good practice anyway, and account credentials should rarely (if ever) be printed<a name="line.50"></a> |
| <FONT color="green">051</FONT> * out for any reason. If you're using Shiro's default implementations of this interface, they only ever print the<a name="line.51"></a> |
| <FONT color="green">052</FONT> * account {@link #getPrincipals() principals}, so you do not need to do anything additional.</p><a name="line.52"></a> |
