PINEntry --------- This is a collection of PIN or passphrase entry dialogs which utilize the Assuan protocol as specified in the Libassuan manual. There are programs for different toolkits available. For all GUIs it is automatically detected which modules can be built, but it can also be requested explicitly. GUI OPTION DEPENDENCIES -------------------------------------------------------------------------- GTK+ V2.0 --enable-pinentry-gtk2 Gimp Toolkit Library, Version 2.0 eg. libgtk-x11-2.0 and libglib-2.0 GNOME --enable-pinentry-gnome GNOME Qt --enable-pinentry-qt Qt (> 4.4.0) Curses --enable-pinentry-curses Curses library, for example ncurses TTY --enable-pinentry-tty Simple TTY version, no dependencies The GTK+, GNOME, and Qt pinentries can fall back to curses mode. The option to enable this is --enable-fallback-curses, but this is also detected automatically in the same way --enable-pinentry-curses is. The fallback to curses also works if --disable-pinentry-curses is specified. So to disable linking to curses completely you have to pass --disable-fallback-curses to the configure script as well. Examples: * To only build the GTK+ pinentry with curses support: ./configure --enable-pinentry-gtk2 --enable-fallback-curses \ --disable-pinentry-curses --disable-pinentry-qt * To build the Qt pinentry, and the other pinentries if they are supported: ./configure --enable-pinentry-qt * To build everything that is supported (complete auto-detection): ./configure Some of the code is taken from Robert Bihlmeyer's Quintuple-Agent. For security reasons, all internationalization has been removed. The client is expected to tell the PIN entry the text strings to be displayed. Curses Pinentry --------------- The curses pinentry supports colors if the terminal does. The colors can be specified by the --colors=FG,BG,SO option, which sets the foreground, background and standout colors respectively. The standout color is used for error messages. Colors can be named by any of "black", "red", "green", "yellow", "blue", "magenta", "cyan" and "white". The foreground and standout color can be prefixed by "bright-", "bright", "bold-" and "bold", and any of these prefixes has the same effect of making the color bolder or brighter. Two special color names are defined as well: "default" chooses the default color, and "none" disables use of colors. The name "none" is only meaningful for the standout color and in this case a reversed effect is used for error messages. For the other colors, disabling colors means the same as using the defaults. The default colors are as follows: Foreground: Terminal default Background: Terminal default Standout: Bright red Note that color support is limited by the capabilities of the display terminal. Some color combinations can be very difficult to read, and please know that colors are perceived differently by different people.
