Hello!
We are pleased to announce the availability of Libgcrypt version 1.11.0.
This release starts a new stable branch of Libgcrypt with full API and
ABI compatibility to the 1.10 series. Over the last years Jussi
Kivilinna put again a lot of work into speeding up the algorithms for
many commonly used CPUs. Niibe-san implemented new APIs and algorithms
and also integrated quantum-resistant encryption algorithms. See below
for a list of improvements and new features in 1.11.
Libgcrypt is a general purpose library of cryptographic building blocks.
It is originally based on code used by GnuPG. It does not provide any
implementation of OpenPGP or other protocols. Thorough understanding of
applied cryptography is required to use Libgcrypt.

Download
========
Source code is hosted at the GnuPG FTP server and its mirrors as listed
at https://gnupg.org/download/mirrors.html. On the primary server
the source tarball and its digital signature are:
https://gnupg.org/ftp/gcrypt/libgcrypt/libgcrypt-1.11.0.tar.bz2
https://gnupg.org/ftp/gcrypt/libgcrypt/libgcrypt-1.11.0.tar.bz2.sig
or gzip compressed:
https://gnupg.org/ftp/gcrypt/libgcrypt/libgcrypt-1.11.0.tar.gz
https://gnupg.org/ftp/gcrypt/libgcrypt/libgcrypt-1.11.0.tar.gz.sig
In order to check that the version of Libgcrypt you downloaded is an
original and unmodified file please follow the instructions found at
https://gnupg.org/download/integrity_check.html. In short, you may
use one of the following methods:
- Check the supplied OpenPGP signature. For example to check the
signature of the file libgcrypt-1.11.0.tar.bz2 you would use this
command:
gpg --verify libgcrypt-1.11.0.tar.bz2.sig libgcrypt-1.11.0.tar.bz2
This checks whether the signature file matches the source file.
You should see a message indicating that the signature is good and
made by one or more of the release signing keys. Make sure that
this is a valid key, either by matching the shown fingerprint
against a trustworthy list of valid release signing keys or by
checking that the key has been signed by trustworthy other keys.
See the end of this mail for information on the signing keys.
- If you are not able to use an existing version of GnuPG, you have
to verify the SHA-1 checksum. On Unix systems the command to do
this is either "sha1sum" or "shasum". Assuming you downloaded the
file libgcrypt-1.11.0.tar.bz2, you run the command like this:
sha1sum libgcrypt-1.11.0.tar.bz2
and check that the output matches the first line from the
this list:
dd2c68e0685bb99249efeeb06046fae15b5214ba libgcrypt-1.11.0.tar.bz2
07737e642eedacbda04e7a1f44c04f3cf8e280b8 libgcrypt-1.11.0.tar.gz
You should also verify that the checksums above are authentic by
matching them with copies of this announcement. Those copies can be
found at other mailing lists, web sites, and search engines.

======
Since 2001 maintenance and development of GnuPG is done by g10 Code GmbH
and has mostly been financed by donations. Several full-time employed
developers and contractors are working exclusively on GnuPG and closely
related software like Libgcrypt, GPGME, Kleopatra and Gpg4win.
Fortunately, and this is still not common with free software, we have
now established a way of financing the development while keeping all our
software free and freely available for everyone. Our model is similar
to the way RedHat manages RHEL and Fedora: Except for the actual binary
of the MSI installer for Windows and client specific configuration
files, all the software is available under the GNU GPL and other Open
Source licenses. Thus customers may even build and distribute their own
version of the software as long as they do not use our trademarks
GnuPG Desktop® or GnuPG VS-Desktop®.
We like to thank all the nice people who are helping the GnuPG project,
be it testing, coding, translating, suggesting, auditing, administering
the servers, spreading the word, answering questions on the mailing
lists, or helping with donations.
*Thank you all*
Your Libgcrypt hackers
