Log message:
Update to 1.4.2.

Noteworthy changes in version 1.4.2 (2005-07-26)
------------------------------------------------

    * New command "verify" in the card-edit menu to display
      the Private-DO-3.  The Admin command has been enhanced to take
      the optional arguments "on", "off" and \ 
"verify".  The latter may
      be used to verify the Admin Pin without modifying data; this
      allows displaying the Private-DO-4 with the "list" command.

    * Rewrote large parts of the card code to optionally make use of a
      running gpg-agent.  If --use-agent is being used and a gpg-agent
      with enabled scdaemon is active, gpg will now divert all card
      operations to that daemon.  This is required because both,
      scdaemon and gpg require exclusive access to the card reader. By
      delegating the work to scdaemon, both can peacefully coexist and
      scdaemon is able to control the use of the reader.  Note that
      this requires at least gnupg 1.9.17.

    * Fixed a couple of problems with the card reader.

    * Command completion is now available in the --edit-key and
      --card-edit menus.  Filename completion is available at all
      filename prompts.  Note that completion is only available if the
      system provides a readline library.

    * New experimental HKP keyserver helper that uses the cURL
      library.  It is enabled via the configure option --with-libcurl
      like the other (also experimental) cURL helpers.

    * New key cleaning options that can be used to remove unusable
      (expired, revoked) signatures from a key.  This is available via
      the new "clean" command in --edit-key on a key by key basis, as
      well as via the import-clean-sigs/import-clean-uids and
      export-clean-sigs/export-clean-uids options for --import-options
      and --export-options.  These are currently off by default, and
      replace the import-unusable-sigs/export-unusable-sigs options
      from version 1.4.1.

    * New export option export-reset-subkey-passwd.

    * New option --limit-card-insert-tries.

Log message:
Drop distinction between PKGSRC_USE_TOOLS and USE_TOOLS by making
PKGSRC_USE_TOOLS go away.  There is now only a single USE_TOOLS variable
that specifies all of the tools we need to build/run the package.

Log message:
Remove USE_GNU_TOOLS and replace with the correct USE_TOOLS definitions:

	USE_GNU_TOOLS	-> USE_TOOLS
	awk		-> gawk
	m4		-> gm4
	make		-> gmake
	sed		-> gsed
	yacc		-> bison

Log message:
gzcat is needed, so note it as such for the new tools framework.

Log message:
Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.

Log message:
Update to 1.4.1:

Noteworthy changes in version 1.4.1 (2005-03-15)
------------------------------------------------

    * New --rfc2440-text option which controls how text is handled in
      signatures.  This is in response to some problems seen with
      certain PGP/MIME mail clients and GnuPG version 1.4.0.  More
      details about this are available at
      <http://lists.gnupg.org/pipermail/gnupg-users/2005-January/024408.html>.

    * New "import-unusable-sigs" and "export-unusable-sigs" \ 
tags for
      --import-options and --export-options.  These are off by
      default, and cause GnuPG to not import or export key signatures
      that are not usable (e.g. expired signatures).

    * New experimental HTTP, HTTPS, FTP, and FTPS keyserver helper
      that uses the cURL library <http://curl.haxx.se> to retrieve
      keys.  This is disabled by default, but may be enabled with the
      configure option --with-libcurl.  Without this option, the
      existing HTTP code is used for HTTP, and HTTPS, FTP, and FTPS
      are not supported.

      [enabled with the "curl" option for the package]

    * When running a --card-status or --card-edit and a public key is
      available, missing secret key stubs will be created on the fly.
      Details of the key are listed too.

    * The implicit packet dumping in double verbose mode is now sent
      to stderr and not to stdout.

    * Added countermeasures against the Mister/Zuccherato CFB attack
      <http://eprint.iacr.org/2005/033>.

    * Add new --edit-key command "bkuptocard" to allow restoring a
      card key from a backup.

    * The "fetch" command of --card-edit now retrieves the key using
      the default keyserver if no URL has been stored on the card.

    * New configure option --enable-noexecstack.

Also, gpgkeys_mailto is not installed any longer, dropping the
dependency on perl.

GnuPG 1.4 Highlights
====================

This is a brief overview of the changes between the GnuPG 1.2 series
and the new GnuPG 1.4 series.  To read the full list of highlights for
each revision that led up to 1.4, see the NEWS file in the GnuPG
distribution.  This document is based on the NEWS file, and is thus
the highlights of the highlights.

When upgrading, note that RFC-2440, the OpenPGP standard, is currently
being revised.  Most of the revisions in the latest draft (2440bis-12)
have already been incorporated into GnuPG 1.4.

Algorithm Changes
-----------------

OpenPGP supports many different algorithms for encryption, hashing,
and compression, and taking into account the OpenPGP revisions, GnuPG
1.4 supports a slightly different algorithm set than 1.2 did.

The SHA256, SHA384, and SHA512 hashes are now supported for read and
write.

The BZIP2 compression algorithm is now supported for read and write.

Due to the recent successful attack on the MD5 hash algorithm
(discussed in <http://www.rsasecurity.com/rsalabs/node.asp?id=2738>,
among other places), MD5 is deprecated for OpenPGP use.  It is still
allowed in GnuPG 1.4 for backwards compatibility, but a warning is
given when it is used.

The TIGER/192 hash is no longer available.  This should not be
interpreted as a statement as to the quality of TIGER/192 - rather,
the revised OpenPGP standard removes support for several unused or
mostly unused hashes, and TIGER/192 was one of them.

Similarly, Elgamal signatures and the Elgamal signing key type have
been removed from the OpenPGP standard, and thus from GnuPG.  Please
do not confuse Elgamal signatures with DSA or DSS signatures or with
Elgamal encryption.  Elgamal signatures were very rarely used and were
not supported in any product other than GnuPG.  Elgamal encryption was
and still is part of OpenPGP and GnuPG.

Very old (pre-1.0) versions of GnuPG supported a nonstandard (contrary
to OpenPGP) Elgamal key type.  While no recent version of GnuPG
permitted the generation of such keys, GnuPG 1.2 could still use them.
GnuPG 1.4 no longer allows the use of these keys or the (also
nonstandard) messages generated using them.

At build time, it is possible to select which algorithms will be built
into GnuPG.  This can be used to build a smaller program binary for
embedded uses where space is tight.

Keyserver Changes
-----------------

GnuPG 1.4 does all keyserver operations via plugin or helper
applications.  This allows the main GnuPG program to be smaller and
simpler.  People who package GnuPG for various reasons have the
flexibility to include or leave out support for any keyserver type as
desired.

Support for fetching keys via HTTP and finger has been added.  This is
mainly useful for setting a preferred keyserver URL like
"http://www.jabberwocky.com/key.asc". or "finger:wk at \ 
g10code.com".

The LDAP keyserver helper now supports storing, retrieving, and
searching for keys in both the old NAI "LDAP keyserver" as well as the
more recent method to store OpenPGP keys in standard LDAP servers.
This is compatible with the storage schema that PGP uses, so both
products can interoperate with the same LDAP server.

The LDAP keyserver helper is compatible with the PGP company's new
"Global Directory" service.

If the LDAP library you use supports LDAP-over-TLS and LDAPS, then
GnuPG detects this and supports them as well.  Note that using TLS or
LDAPS does not improve the security of GnuPG itself, but may be useful
in certain key distribution scenarios.

HTTP Basic authentication is now supported for all HKP and HTTP
keyserver functions, either through a proxy or via direct access.

The HKP keyserver plugin supports the new machine-readable key
listing format for those keyservers that provide it.

IPv6 is supported for HKP and HTTP keyserver access.

When using a HKP keyserver with multiple DNS records (such as
subkeys.pgp.net which has the addresses of multiple servers around the
world), all DNS address records are tried until one succeeds.  This
prevents a single down server in the rotation from stopping access.

DNS SRV records are used in HKP keyserver lookups to allow
administrators to load balance and select keyserver ports
automatically.

Timeout support has been added to the keyserver plugins.  This allows
users to set an upper limit on how long to wait for the keyserver
before giving up.

Preferred Keyserver URL
-----------------------

Preferred keyserver support has been added.  Users may set a preferred
keyserver via the --edit-key command "keyserver".  If the
--keyserver-option honor-keyserver-url is set (and it is by default),
then the preferred keyserver is used when refreshing that key with
--refresh-keys.

The --sig-keyserver-url option can be used to inform signature
recipients where the signing key can be downloaded.  When verifying
the signature, if the signing key is not present, and the keyserver
options honor-keyserver-url and auto-key-retrieve are set, this URL
will be used to retrieve the key.

Trust Signatures
----------------

GnuPG 1.4 supports OpenPGP trust signatures, which allow a user to
specify the trust level and distance from the user along with the
signature so users can delegate different levels of certification
ability to other users, possibly restricted by a regular expression on
the user ID.

Trust Models
------------

GnuPG 1.4 supports several ways of looking at trust:

Classic - The classic PGP trust model, where people sign each others
          keys and thus build up an assurance (called "validity") that
          the key belongs to the right person.  This was the default
          trust model in GnuPG 1.2.

Always - Bypass all trust checks, and make all keys fully valid.

Direct - Users may set key validity directly.

PGP - The PGP 7 and 8 behavior which combines Classic trust with trust
      signatures overlaid on top.  This is the default trust model in
      GnuPG 1.4.

The OpenPGP Smartcard
---------------------

GnuPG 1.4 supports the OpenPGP smartcard
(<http://www.g10code.de/p-card.html>)

Secret keys may be kept fully or partially on the smartcard.  The
smartcard may be used for primary keys or subkeys.

Other Interesting New Features
------------------------------

For those using Security-Enhanced Linux <http://www.nsa.gov/selinux/>,
the configure option --enable-selinux-support prevents GnuPG from
processing its own files (i.e. reading the secret keyring for
something other than getting a secret key from it).  This simplifies
writing ACLs for the SELinux kernel.

Readline support is now available at all prompts if the system
provides a readline library.

GnuPG can now create messages that can be decrypted with either a
passphrase or a secret key.  These messages may be generated with
--symmetric --encrypt or --symmetric --sign --encrypt.

--list-options and --verify-options allow the user to customize
exactly what key listings or signature verifications look like,
enabling or disabling things such as photo display, preferred
keyserver URL, calculated validity for each user ID, etc.

The --primary-keyring option designates the keyring that the user
wants new keys imported into.

The --hidden-recipient (or -R) command encrypts to a user, but hides
the identity of that user.  This is the same functionality as
--throw-keyid, but can be used on a per-user basis.

Full algorithm names (e.g. "3DES", "SHA1", "ZIP") \ 
can now be used
interchangeably with the short algorithm names (e.g. "S2", \ 
"H2", "Z1")
anywhere algorithm names are used in GnuPG.

The --keyid-format option selects short (99242560), long
(DB698D7199242560), 0xshort (0x99242560), or 0xlong
(0xDB698D7199242560) key ID displays.  This lets users tune the
display to what they prefer.

While it is not recommended for extended periods, it is possible to
run both GnuPG 1.2.x and GnuPG 1.4 during the transition.  To aid in
this, GnuPG 1.4 tries to load a config file suffixed with its version
before it loads the default config file.  For example, 1.4 will try
for gpg.conf-1.4 and gpg.conf-1 before falling back to the regular
gpg.conf file.
