.Nm password.lua
|
|
.Nd FreeBSD password module
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
contains functionality for prompting for and checking passwords.
|
|
.Pp
|
|
Before using the functionality provided by
|
|
.Nm ,
|
|
it must be included with a statement such as the following:
|
|
.Pp
|
|
.Dl local password = require("password")
|
|
.Pp
|
|
The following functions are exported from
|
|
.Nm :
|
|
.Bl -tag -width "Fn password.read prompt_length" -offset indent
|
|
.It Fn password.read prompt_length
|
|
Read a password following a prompt.
|
|
.Fa prompt_length
|
|
is required so that the twiddle may be properly drawn as the user is typing.
|
|
.It Fn password.check
|
|
Drives the primary password checks done by the loader.
|
|
The
|
|
.Fn password.check
|
|
function will check
|
|
.Ev bootlock_password ,
|
|
.Ev geom_eli_passphrase_prompt ,
|
|
and
|
|
.Ev password
|
|
and prompt the user for passwords as-needed.
|
|
If
|
|
.Ev password
|
|
is set, the autoboot sequence will begin as the user is prompted for a password.
