30   * <b>Note:</b> <a href="http://en.wikipedia.org/wiki/MD5">MD5</a> and
31   * <a href="http://en.wikipedia.org/wiki/SHA_hash_functions">SHA-1</a> algorithms are now known to be vulnerable to

33   * two, if your application mandates high security, use the SHA-256 (or higher) hashing algorithms and their
34   * supporting <code>CredentialsMatcher</code> implementations.</p>
35   *
36   * @since 0.9
37   * @deprecated since 1.1 - use the HashedCredentialsMatcher directly and set its
