[Bug 2142721] Re: sudo-rs echos * for every character typed breaking historical security measures older than I am

[Seth Arnold]

Please note, unless you've got a *very* unique setup, anyone who is
close enough to see see asterisks on your screen is also close enough to
hear your typing (perhaps even with the same telephoto lens), see your
screen wobble, and so on.

Furthermore, the password length should not matter for your security. If
it does, your password is too short or your PBKDF is too easy. Increase
lengths or costs as appropriate.

Title:
  sudo-rs echos * for every character typed breaking historical security
  measures older than I am

Status in rust-sudo-rs package in Ubuntu:
  Won't Fix

Bug description:
  Just upgraded 26.04 amd64v3 to sudo-rs 0.2.12-0ubuntu1

  Before this upgrade, as expected, typing a password in a terminal
  echos NOTHING.

  After this upgrade, I get STARS ECHOED.

  WHY?!

  This goes against DECADES of NOT ECHOING THE LENGTH OF THE PASSWORD TO
  SHOULDER SURFERS.

  FIX THIS.
