+:mod:`spwd` --- The shadow password database
+============================================
+
+.. module:: spwd
+   :platform: Unix
+   :synopsis: The shadow password database (getspnam() and friends).
+
+
+.. versionadded:: 2.5
+
+This module provides access to the Unix shadow password database. It is
+available on various Unix versions.
+
+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                         |

++-------+---------------+---------------------------------+
+| 1     | ``sp_pwd``    | Encrypted password              |

++-------+---------------+---------------------------------+
+| 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        |
+|       |               | blocked                         |
++-------+---------------+---------------------------------+
+| 7     | ``sp_expire`` | Number of days since 1970-01-01 |

+The sp_nam and sp_pwd items are strings, all others are integers.
+:exc:`KeyError` is raised if the entry asked for cannot be found.
+
+It defines the following items:
+
+
+.. function:: getspnam(name)
+
+   Return the shadow password database entry for the given user name.
+
+
+.. function:: getspall()
+
+   Return a list of all available shadow password database entries, in arbitrary
+   order.
+
+
+.. seealso::
+
+   Module :mod:`grp`
+      An interface to the group database, similar to this.
+
+   Module :mod:`pwd`
+      An interface to the normal password database, similar to this.
