     <function>mcrypt_list_algorithms</function> is used to get an
     array of all supported algorithms in the <parameter>lib_dir</parameter> parameter.

    <para>
     <function>mcrypt_list_algorithms</function> takes an optional
     <parameter>lib_dir</parameter> parameter which specifies the directory
     where all algorithms are located. If not specifies, the value of the
     mcrypt.algorithms_dir &php.ini; directive is used.
