The GnuPG Project is pleased to announce the availability of Libgcrypt
version 1.9.2. This is a maintenance release.
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.

- Fix building with --disable-asm on x86. [#5277]
- Check public key for ECDSA verify operation. [#5282]
- Make sure gcry_get_config (NULL) returns a nul-terminated string.

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:

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-1.9.2.tar.bz2 you would use this
gpg --verify libgcrypt-1.9.2.tar.bz2.sig libgcrypt-1.9.2.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-1.9.2.tar.bz2, you run the command like this:
and check that the output matches the first line from the
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 still mostly financed by donations. Three full-time employed
developers as well as two contractors exclusively work on GnuPG and
closely related software like Libgcrypt, GPGME, and Gpg4win.
We like to thank all the nice people who are helping Libgcrypt, be it
testing, coding, suggesting, auditing, administering the servers,
spreading the word, or answering questions on the mailing lists.
Many thanks to our numerous financial supporters, both corporate and
individuals. Without you it would not be possible to keep GnuPG and
Libgcrypt in a good and secure shape and to address all the small and
larger requests made by our users. Thanks.
