Hi -
I'm creating a package of database tools. A function in the package
requires the username and password as input to the function in order to
initially connect to the target database(s). Of course, this poses a
significant security issue given the possible retention of the function
statement in cleartext. I did not readily encounter a package meant to mask
input from the user nor do I know of any method to prevent sensitive
information from appearing on-screen or from logging in the command history
of a running R session. While using the --vanilla option when starting R
helps with permanent logging of sensitive information, it is not always
preferable to run R with special flags. Is any solution available to
prevent the logging/ display of user input. Obviously, hard-coding the
sensitive information is not an option.
Note: I currently use the following (summarized) convention:
myloginfunction <- function(uname = readline("Enter username") , passwd =
readline("Enter password")) { print(c(uname,passwd)); };
However, the readline function prints the response on-screen.
Thanks!
