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

[Karsten Stieg]

I can confirm this bug.

I have a crypted root-partition, where everything is fine (* for each
key pressed, no clear text shown), but with my crypted data-raid-
partition it's the same as mentioned above.

Since it's a data-partition and not needed for boot-up, I set noauto in
fstab, took it out of crypttab, created a startscript
'init.d/cryptmount' and did a 'update-rc.d -f cryptmount defaults 99'
with it. Voilá, didn't solve the problem but have a workaround, password
is not shown anymore. Works for now.

Best regards,
Karsten

Title:
  crypttab LUKS password shown in cleartext

Status in “upstart” package in Ubuntu:
  Triaged

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.
