spwd --- shadow 密碼資料庫

Deprecated since version 3.11, will be removed in version 3.13: spwd 模組 (module) 即將被棄用（詳情與替代方案請見 PEP 594）。

---

This module provides access to the Unix shadow password database. It is available on various Unix versions.

Availability: not Emscripten, not WASI.

此模組在 WebAssembly 平台 wasm32-emscripten 和 wasm32-wasi 上無法作用或無法使用。有關更多資訊，請參閱 WebAssembly 平台。

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	屬性	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. KeyError is raised if the entry asked for cannot be found.

The following functions are defined:

spwd.getspnam(name)

Return the shadow password database entry for the given user name.

在 3.6 版的變更: Raises a PermissionError instead of KeyError if the user doesn't have privileges.

spwd.getspall()

Return a list of all available shadow password database entries, in arbitrary order.
