 /**

  * {@code HashedCredentialsMatcher} implementation that expects the stored {@code AuthenticationInfo} credentials to be

  * SHA hashed.

  * <p/>

  * <b>Note:</b> <a href="http://en.wikipedia.org/wiki/MD5">MD5</a> and

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

  * compromise and/or collisions (read the linked pages for more).  While most applications are ok with either of these

  * two, if your application mandates high security, use the SHA-256 (or higher) hashing algorithms and their

  * supporting <code>CredentialsMatcher</code> implementations.</p>

  *

  * @since 0.9

  * @deprecated since 1.1 - use the HashedCredentialsMatcher directly and set its

  *             {@link HashedCredentialsMatcher#setHashAlgorithmName(String) hashAlgorithmName} property.
