getpass — 이식성 있는 암호 입력

소스 코드: Lib/getpass.py

가용성: not WASI.

이 모듈은 웹어셈블리에서 작동하지 않거나 제공되지 않습니다. 자세한 내용은 웹어셈블리 플랫폼을 참조하세요.

The getpass module provides two functions:

getpass.getpass(prompt='Password: ', stream=None, *, echo_char=None)

Prompt the user for a password without echoing. The user is prompted using the string prompt, which defaults to 'Password: '. On Unix, the prompt is written to the file-like object stream using the replace error handler if needed. stream defaults to the controlling terminal (/dev/tty) or if that is unavailable to sys.stderr (this argument is ignored on Windows).

The echo_char argument controls how user input is displayed while typing. If echo_char is None (default), input remains hidden. Otherwise, echo_char must be a single printable ASCII character and each typed character is replaced by it. For example, echo_char='*' will display asterisks instead of the actual input.

If echo-free input is unavailable, getpass() falls back to printing a warning message to stream and reading from sys.stdin and issuing a GetPassWarning.

참고

If you call getpass() from within IDLE, the input may be done in the terminal you launched IDLE from rather than the idle window itself.

참고

On Unix systems, when echo_char is set, the terminal will be configured to operate in noncanonical mode. Common terminal control characters are supported:

  • Ctrl+A - Move cursor to beginning of line

  • Ctrl+E - Move cursor to end of line

  • Ctrl+K - Kill (delete) from cursor to end of line

  • Ctrl+U - Kill (delete) entire line

  • Ctrl+W - Erase previous word

  • Ctrl+V - Insert next character literally (quote)

  • Backspace/DEL - Delete character before cursor

These shortcuts work by reading the terminal’s configured control character mappings from termios settings.

버전 3.14에서 변경: Added the echo_char parameter for keyboard feedback.

버전 3.15에서 변경: When using non-empty echo_char on Unix, keyboard shortcuts (including cursor movement and line editing) are now properly handled using the terminal’s control character configuration.

exception getpass.GetPassWarning

패스워드 입력이 에코 될 때 방출되는 UserWarning 서브 클래스.

getpass.getuser()

사용자의 “로그인 이름”을 반환합니다.

이 함수는 환경 변수 LOGNAME, USER, LNAME 및 USERNAME를 순서대로 검사하고, 비어 있지 않은 문자열로 설정된 첫 번째 값을 반환합니다. 아무것도 설정되지 않았으면, pwd 모듈을 지원하는 시스템에서는 암호 데이터베이스의 로그인 이름이 반환되고, 그렇지 않으면 OSError가 발생합니다.

일반적으로, 이 함수는 os.getlogin()보다 선호됩니다.

버전 3.13에서 변경: Previously, various exceptions beyond just OSError were raised.
