026/**
027 * {@code HashedCredentialsMatcher} implementation that expects the stored {@code AuthenticationInfo} credentials to be
028 * SHA hashed.
029 * <p/>
030 * <b>Note:</b> <a href="http://en.wikipedia.org/wiki/MD5">MD5</a> and
031 * <a href="http://en.wikipedia.org/wiki/SHA_hash_functions">SHA-1</a> algorithms are now known to be vulnerable to
032 * compromise and/or collisions (read the linked pages for more).  While most applications are ok with either of these
033 * two, if your application mandates high security, use the SHA-256 (or higher) hashing algorithms and their
034 * supporting <code>CredentialsMatcher</code> implementations.</p>
035 *
036 * @since 0.9
037 * @deprecated since 1.1 - use the HashedCredentialsMatcher directly and set its
038 *             {@link HashedCredentialsMatcher#setHashAlgorithmName(String) hashAlgorithmName} property.
