is an X11-based pass-phrase dialog for
use with OpenSSH. It is intended to be called from the program and not
invoked directly. supports most standard Toolkit command line arguments,
with the exception of and See If exactly one non-option argument
is provided on the command line, it is displayed in the dialog instead
of the default label. The features of are as follows: Configurable via
the standard X resource mechanisms etc. Requires only stock X11 libraries
(libXt, libX11, libSM, libICE). Can be configured to grab the keyboard
and/or pointer (grabs the keyboard by default, not the pointer). The user
interface is somewhat different than most password/pass-phrase dialogs and
more similar to the X11-based pass-phrase dialog that accompanies the regular
SSH distribution. Instead of a text field that fills with asterisks or some
other character as the user enters the pass-phrase, a series of LED-like
areas light up one-by-one with each pass-phrase character entered, beginning
from the left-hand edge of the dialog. When they reach the right-hand edge,
they go dark one-by-one again, and so on. This gives the user feedback that
pass-phrase characters have been entered, but does not provide onlookers
with a cue as to the length of the pass-phrase. Pressing the button accepts
the pass-phrase (even if it is empty), which is printed on the standard
output, and the dialog exits with a status of zero (success). Pressing the
button discards the pass-phrase, and the dialog exits with non-zero status.
The following keystrokes work as expected: Erase previous character
Erase entire pass-phrase Accept pass-phrase (OK) Discard pass-phrase
(Cancel)

are intended for. If the actual horizontal (x) resolution of the X server
is significantly greater or less than this value, portions of the dialog,
indicator, and button widgets are stretched or shrunk horizontally to take
the difference into account. The value is a positive integer, followed by
a slash and a one- or two-character unit abbreviation. Valid units are inches

the difference into account. Valid values are the same as for above. (75

per inch or greater than 125 pixels per inch. (20 pixels per inch).
