Prompting for a password in Haskell command line application

Question

The following Haskell program prompts the user for a password in the terminal and continues if he has entered the correct one:

main = do
    putStrLn \"Password:         


        

Answer 1

There is a getPassword in System.Console.Haskeline. Probably it's an overkill for your case but someone may find it useful.

An example:

> runInputT defaultSettings $ do {p <- getPassword (Just '*') "pass:"; outputStrLn $ fromJust p}
pass:***
