-.Sh PASS PHRASE ARGUMENTS
-Several commands accept password arguments, typically using
-.Fl passin
-and
-.Fl passout
-for input and output passwords, respectively.
-These allow the password to be obtained from a variety of sources.
-Both of these options take a single argument whose format is described below.
-If no password argument is given and a password is required,
-then the user is prompted to enter one:
-this will typically be read from the current terminal with echoing turned off.
-.Bl -tag -width "fd:number"
-.It Ar pass : Ns Ar password
-The actual password is
-.Ar password .
-Since the password is visible to utilities
-(like

-.It Ar env : Ns Ar var
-Obtain the password from the environment variable

-.It Ar file : Ns Ar path
-The first line of
