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 programme to use.

     GPG_TERM  Terminal type of the current tty.

     GPG_TTY   The current terminal.

     PINENTRY  The pinentry programme 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.
