[Bug 877403] Re: crypttab LUKS password shown in cleartext

[Johannes Bauer]

Hi Dave,

1) Just one partition, my home
2) I manually edited crypttab:
crypthome	UUID=foo-bar-bar-foo	none	luks

3) I edited /etc/grub/default/grub and changed

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="gfxpayload=text"

also uncommented (but that shouldn't matter)

GRUB_TERMINAL=console

Then reran update-grub. This gives me nice text-only no-framebuffer
bootup.

About the swaring: You are of course correct, I will avoid that in the
future. One should not write bug reports when annoyed, I guess. My
apologies.

Best regards,
Joe

Title:
  crypttab LUKS password shown in cleartext

Status in “upstart” package in Ubuntu:
  New

Bug description:
  After updating to 11.10, I was shocked to see that passwords that are
  used for LUKS disk encryption are now shown in cleartext while
  entrering them. I am not using the (incredibly stupid/ugly, BTW)
  splash screen, but regular startup. It does not matter wheter
  framebuffer is enabled or not. When the point comes where I should
  enter my password, I see the

  Enter passphrase:

  prompt. When I enter my password there, it appears in clear text! This
  means I see

  Enter passphrase: mypassubuntufuckedup1234

  Only when I press enter do I see the passphrase in asterisks, i.e.

  Enter passphrase: mypassubuntufuckedup1234
  Enter passphrase: ************************

  This is - as you can image - not very helpful (since the password is
  already there in clear text).

  I have this problem on one system which I upgraded from Natty and one
  one fresh install that I just did.
