研究方向

未指定檔案、測試或進入點。首先比較 ipykernel 的 getpass 替代實作與 Python 的標準 getpass API,重點關注何時發出 GetPassWarning;完成的標準是呼叫端能在要求密碼之前偵測到不安全的提示。

由索引模型根據 Issue 內容生成。

描述

The getpass API requires that the GetPassWarning is generated in case a password cannot be asked to the user in a secure way.

This is an important piece of the API, because it lets the programmer turn the warning into an error to handle the case when the terminal is not suited to securely prompt for a password before the user is asked for a password. In turn this is important because most users will carelessly type in a password regardless of any warning and is particularly bad for interfaces where the password will remain available for view via scrollback. Being able to handle the condition will let the program try different ways to get the password rather than prompting the user in an insecure way.

The problem here is that ipykernel replaces getpass with its own version that does not issue the GetPassWarning, so resulting in a different API from the standard getpass that ends up with the code prompting the user for a password insecurely without even realizing it.

At present time the workaround is clearly for the code to check if getpass comes from ipykernel and deal with this case specially.
