--------------
This module provides access to the Unix shadow password database. It is
available on various Unix versions.
.. include:: ../includes/wasm-notavail.rst
You must have enough privileges to access the shadow password database (this
usually means you have to be root).
Shadow password database entries are reported as a tuple-like object, whose
attributes correspond to the members of the ``spwd`` structure (Attribute field
below, see ``<shadow.h>``):
+-------+---------------+---------------------------------+
| Index | Attribute | Meaning |
+=======+===============+=================================+
| 0 | ``sp_namp`` | Login name |
+-------+---------------+---------------------------------+
| 1 | ``sp_pwdp`` | Encrypted password |
+-------+---------------+---------------------------------+
| 2 | ``sp_lstchg`` | Date of last change |
+-------+---------------+---------------------------------+
| 3 | ``sp_min`` | Minimal number of days between |
| | | changes |
+-------+---------------+---------------------------------+
| 4 | ``sp_max`` | Maximum number of days between |
| | | changes |
+-------+---------------+---------------------------------+
| 5 | ``sp_warn`` | Number of days before password |
| | | expires to warn user about it |
+-------+---------------+---------------------------------+
| 6 | ``sp_inact`` | Number of days after password |
| | | expires until account is |
| | | disabled |
+-------+---------------+---------------------------------+
| 7 | ``sp_expire`` | Number of days since 1970-01-01 |
| | | when account expires |
+-------+---------------+---------------------------------+
| 8 | ``sp_flag`` | Reserved |
+-------+---------------+---------------------------------+
The sp_namp and sp_pwdp items are strings, all others are integers.
:exc:`KeyError` is raised if the entry asked for cannot be found.
The following functions are defined:
.. function:: getspnam(name)
Return the shadow password database entry for the given user name.
.. versionchanged:: 3.6
Raises a :exc:`PermissionError` instead of :exc:`KeyError` if the user
doesn't have privileges.
.. function:: getspall()
Return a list of all available shadow password database entries, in arbitrary
order.
