<p class="last" id="index-0">In traditional Unix the field <tt class="docutils literal"><span class="pre">pw_passwd</span></tt> usually contains a password
encrypted with a DES derived algorithm (see module <a class="reference internal" href="crypt.html#module-crypt" title="crypt: The crypt() function used to check Unix passwords. (Unix)"><tt class="xref py py-mod docutils literal"><span class="pre">crypt</span></tt></a>).  However most
modern unices  use a so-called <em>shadow password</em> system.  On those unices the
<em>pw_passwd</em> field only contains an asterisk (<tt class="docutils literal"><span class="pre">'*'</span></tt>) or the  letter <tt class="docutils literal"><span class="pre">'x'</span></tt>
where the encrypted password is stored in a file <tt class="file docutils literal"><span class="pre">/etc/shadow</span></tt> which is
not world readable.  Whether the <em>pw_passwd</em> field contains anything useful is
system-dependent.  If available, the <a class="reference internal" href="spwd.html#module-spwd" title="spwd: The shadow password database (getspnam() and friends). (Unix)"><tt class="xref py py-mod docutils literal"><span class="pre">spwd</span></tt></a> module should be used where
access to the encrypted password is required.</p>
