impersonation

A utility that allows a certain routine to run under a given user. To achieve this, a process will run under the uid and gid of the intended user. For that reason, it is a requirement that the running process has SETUID and SETGID capabilities.

Features

@impersonate("username")
class Printer:
    def __init__(self, prefix=""):
        self.prefix = prefix

    def printer1(self, string):
        print(f"{self.prefix}{string}")
