Comment 38 for bug 876626

Thanks for finally looking into this.

While on this, please also look at #778659.
I do not agree with Comment #33 that "[obscuring] the entered passphrase and [displaying] asterisks" is "correct". It should not display any input, as cryptsetup(8), cryptdisks_start(8), passwd(1), gpg(1) and all others do.
