[jboss-jira] [JBoss JIRA] (ELY-126) Consider adding credential verification to realm API

[David Lloyd (JIRA)]

    [ https://issues.jboss.org/browse/ELY-126?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13026797#comment-13026797 ] 

David Lloyd commented on ELY-126:
---------------------------------

Here's a proposal API:

{code}
public interface RealmIdentity {
//  [...]
    /**
     * Verify the given credential.  The result is one of the following:
     * <ul>
     *     <li>{@link VerificationResult#DENIED} - the credential is not valid</li>
     *     <li>{@link VerificationResult#UNVERIFIED} - the credential is not supported or could not be verified; retry with another credential type</li>
     *     <li>{@link VerificationResult#VERIFIED} - the credential is valid and verified</li>
     * </ul>
     *
     * @param credential the credential to verify
     * @return the non-{@code null} verification result
     */
    VerificationResult verifyCredential(Object credential);
//  [...]
}
{code}

It does require that realms all support this method, which at the least would have to support {{char[]}} credentials for password verification.

> Some realms may not be able to acquire credentials.  These realms will need a verification API (not like the old verification API though).
