GNU Privacy Guard for Windows =============================== This is GnuPG for Windows, version 2.2.5. Content: 1. Important notes 2. Changes 3. GnuPG README file 4. Package versions 5. Legal notices 1. Important Notes ================== This is the core part of the GnuPG system as used by several other frontend programs. This installer does not provide any graphical frontend and thus almost everything needs to be done on the command line. However, a small native Windows GUI tool is included which is used by GnuPG to ask for passphrases. It provides only the basic functionality and is installed under the name "pinentry-basic.exe". Other software using this core component may install a different version of such a tool under the name "pinentry.exe" or configure the gpg-agent to use that version. See https://gnupg.org for latest news. HowTo documents and manuals can be found there but some have also been installed on your machine. Development and maintenance of GnuPG is mostly financed by donations; please see https://gnupg.org/donate/ for details. 2. Record of Changes ==================== This is a list of changes to the GnuPG core for this and the previous release. Noteworthy changes in version 2.2.5 (2018-02-22) ------------------------------------------------ * gpg: Allow the use of the "cv25519" and "ed25519" short names in addition to the canonical curve names in --batch --gen-key. * gpg: Make sure to print all secret keys with option --list-only and --decrypt. [#3718] * gpg: Fix the use of future-default with --quick-add-key for signing keys. [#3747] * gpg: Select a secret key by checking availability under gpg-agent. [#1967] * gpg: Fix reversed prompt texts for --only-sign-text-ids. [#3787] * gpg,gpgsm: Fix detection of bogus keybox blobs on 32 bit systems. [#3770] * gpgsm: Fix regression since 2.1 in --export-secret-key-raw which got $d mod (q-1)$ wrong. Note that most tools automatically fixup that parameter anyway. * ssh: Fix a regression in getting the client'd PID on *BSD and macOS. * scd: Support the KDF Data Object of the OpenPGP card 3.3. [#3152] * scd: Fix a regression in the internal CCID driver for certain card readers. [#3508] * scd: Fix a problem on NetBSD killing scdaemon on gpg-agent shutdown. [#3778] * dirmngr: Improve returned error description on failure of DNS resolving. [#3756] * wks: Implement command --install-key for gpg-wks-server. * Add option STATIC=1 to the Speedo build system to allow a build with statically linked versions of the core GnuPG libraries. Also use --enable-wks-tools by default by Speedo builds for Unix. Noteworthy changes in version 2.2.4 (2017-12-20) ------------------------------------------------ * gpg: Change default preferences to prefer SHA512. * gpg: Print a warning when more than 150 MiB are encrypted using a cipher with 64 bit block size. * gpg: Print a warning if the MDC feature has not been used for a message. * gpg: Fix regular expression of domain addresses in trust signatures. [#2923] * agent: New option --auto-expand-secmem to help with high numbers of concurrent connections. Requires libgcrypt 1.8.2 for having an effect. [#3530] * dirmngr: Cache responses of WKD queries. * gpgconf: Add option --status-fd. * wks: Add commands --check and --remove-key to gpg-wks-server. * Increase the backlog parameter of the daemons to 64 and add option --listen-backlog. * New configure option --enable-run-gnupg-user-socket to first try a socket directory which is not removed by systemd at session end.

The GNU Privacy Guard 2 ========================= Version 2.2 Copyright 1997-2018 Werner Koch Copyright 1998-2018 Free Software Foundation, Inc. * INTRODUCTION GnuPG is a complete and free implementation of the OpenPGP standard as defined by RFC4880 (also known as PGP). GnuPG enables encryption and signing of data and communication, and features a versatile key management system as well as access modules for public key directories. GnuPG, also known as GPG, is a command line tool with features for easy integration with other applications. A wealth of frontend applications and libraries are available that make use of GnuPG. Starting with version 2 GnuPG provides support for S/MIME and Secure Shell in addition to OpenPGP. GnuPG is Free Software (meaning that it respects your freedom). It can be freely used, modified and distributed under the terms of the GNU General Public License. Note that the 2.0 series of GnuPG will reach end-of-life on 2017-12-31. It is not possible to install a 2.2.x version along with any 2.0.x version. * BUILD INSTRUCTIONS GnuPG 2.2 depends on the following GnuPG related packages: npth (https://gnupg.org/ftp/gcrypt/npth/) libgpg-error (https://gnupg.org/ftp/gcrypt/libgpg-error/) libgcrypt (https://gnupg.org/ftp/gcrypt/libgcrypt/) libksba (https://gnupg.org/ftp/gcrypt/libksba/) libassuan (https://gnupg.org/ftp/gcrypt/libassuan/) You should get the latest versions of course, the GnuPG configure script complains if a version is not sufficient. For some advanced features several other libraries are required. The configure script prints diagnostic messages if one of these libraries is not available and a feature will not be available.. You also need the Pinentry package for most functions of GnuPG; however it is not a build requirement. Pinentry is available at https://gnupg.org/ftp/gcrypt/pinentry/ . After building and installing the above packages in the order as given above, you may continue with GnuPG installation (you may also just try to build GnuPG to see whether your already installed versions are sufficient). As with all packages, you just have to do ./configure make make check make install The "make check" is optional but highly recommended. To run even more tests you may add "--enable-all-tests" to the configure run. Before running the "make install" you might need to become root. If everything succeeds, you have a working GnuPG with support for OpenPGP, S/MIME, ssh-agent, and smartcards. Note that there is no binary gpg but a gpg2 so that this package won't conflict with a GnuPG 1.4 installation. gpg2 behaves just like gpg. In case of problem please ask on the [email protected] mailing list for advise. Instruction on how to build for Windows can be found in the file doc/HACKING in the section "How to build an installer for Windows". This requires some experience as developer. Note that the PKITS tests are always skipped unless you copy the PKITS test data file into the tests/pkits directory. There is no need to run these test and some of them may even fail because the test scripts are not yet complete. You may run gpgconf --list-dirs to view the default directories used by GnuPG. To quickly build all required software without installing it, the Speedo method may be used: make -f build-aux/speedo.mk native This method downloads all required libraries and does a native build of GnuPG to PLAY/inst/. GNU make is required and you need to set LD_LIBRARY_PATH to $(pwd)/PLAY/inst/lib to test the binaries. ** Specific build problems on some machines: *** Apple OS
