NAME

     pinentry-kwallet — kwallet-based pass-phrase dialog for use with GnuPG

SYNOPSIS

     pinentry-kwallet [-q] [options]

DESCRIPTION

     pinentry-kwallet is a kwallet- and pinentry-based pass-phrase dialog for use with GnuPG.  It is intended to
     be called from the gpg-agent(1) daemon and not invoked directly.

     pinentry-kwallet replaces the regular pinentry-program stanza set in ~/.gnupg/gpg-agent.conf and looks up
     the passphrases requested in the KWallet first, falling back to pinentry only if not found.  The user is
     given the option to store it in the KWallet afterwards.  Negative answers to this are also stored in the
     KWallet to avoid asking each time.

     pinentry-kwallet (like other pinentry variants) talks a simplified subset of the regular Assuan protocol on
     stdio; all commands, even unknown ones, are passed through to a pinentry co-process during run-time, even
     if the latter is never used.  It accepts the same options as pinentry, even unknown ones, because it is
     designed to plug in.  As an exception, -q makes pinentry-kwallet more quiet (suppress warnings on stderr),
     and -V displays the version on stderr (unless -q).

     pinentry-kwallet attempts sophisticated error handling: if an error dialogue is displayed, an internal
     counter is increased.  If the counter reaches 2, the value stored in the KWallet is ignored, and the user
     is asked anew.  The counter is stored in the KWallet, which is suboptimal but necessary, because gpg2(1)
     does not re-use the Assuan sessions, instead spawning a new pinentry-kwallet each time a passphrase is
     required (rather stupid).  Error counters are valid for 15 seconds since their last increasement.

RETURN VALUES

     pinentry-kwallet exits 1 if it is called recursively, 0 if help or version information are requested, and
     return codes do not matter in any other cases because errors are signalled in-band.  It will exit 0 after
     the Assuan session is terminated.

ENVIRONMENT

     DISPLAY   The X11 display to use for child processes.  If not set, pinentry-kwallet will immediately
               replace itself with the slave PINENTRY program to use.

     GPG_TERM  Terminal type of the current tty.

     GPG_TTY   The current terminal.

     PINENTRY  The pinentry program to use.  Default: “pinentry”

CAVEATS

     Some newer pinentry features, such as three-button operation, are not supported yet.

     Some commands, such as version inquiry, as passed through to the pinentry coprocess indiscriminately, which
     may lead to strange results, should the protocol change or extend.
