* calculation of marginals never yields a completely trusted key.

    * list-keys:  change valid-days to key expiration date

    * disable comments but those in secret keyrings.

    * abgelaufene secret keys verhinder ein korrektes initialisieren der
      Trustdb.

    * import should skip all ascii armored messages headers which are
      not keys (some folks are mailing signed public keyblocks :-)

    * The critical bit of signature subpackets is not yet supported; i.e.
      it is ignored.

    * Read more records at once in tdbio.c and provide a lazy write cache.

    * Exportable Certification Flag is ignored

    * Why does OpenPGP say: The algorithm byte is included in the
      checksum of an encoded key, but the actual implementaion does
      not do this but works - According to Hal Finney, this is a bug
      in the specs.

    * fix armor problems (see mails by Brian Moore).

    * write a tool to extract selected keys from a file.

    * new menu to delete signatures and list signature in menu

    * commandline controlled --edit-key with assumed save.

    * -rdynamic auf Solaris Problem

    * if --libdir is used, the extensions are put in a wrong place.
      How does GNOME handle this or make a new option for this directory.
      Hmmm, I donī like to pass ot as a commandline option to cc.

    * Replace the SIGUSR1 stuff by semaphores to avoid loss of a signal.

    * add test cases for invalid data (scrambled armor or other random data)

    * add some sanity checks to read_keyblock, so that we are sure that
     the minimal requirements are met (?)

    * decryption of message with multiple recipients does not work.

    * preferences of hash algorithms are not yet used.

    * rewrite --list-packets or put it into another tool.

    * Burn the buffers used by fopen(), or use read(2). Does this
      really make sense?

    * Change the buffering to a mbuf like scheme? Need it for PSST anyway.
    * add checking of armor trailers
    * remove all "Fixmes"

    * Change the internal represention of keyid into a struct which
      can also hold the localid and extend the localid to hold information
      of the subkey number because two subkeys may have the same keyid.

    * add an option to re-create a public key from a secret key. Think about
      a backup system of only the secret part of the secret key.

    * OpenBSD has sometimes problems reading from /dev/random.

    * change the fake_data stuff to mpi_set_opaque

    * Is it okay to use gettext for the help system?

    * Add some stuff for DU cc

    * use "passphrase" instead of "pass phrase"
    * Use "user ID", "trustdb" and "WARNING".
