Mon Mar 28 16:40:13 CEST 2022
We are pleased to announce the availability of Libgcrypt version 1.10.1.
This release starts a new stable branch of Libgcrypt with full API and
ABI compatibility to the 1.9 series. Over the last year Jussi Kivilinna
put again a lot of work into speeding up the algorithms for the most
commonly used CPUs. See below for a list of improvements and new
features in 1.10.
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.
Noteworthy changes in Libgcrypt 1.10.0 and 1.10.1
* New and extended interfaces:
- New control codes to check for FIPS 140-3 approved algorithms.
- New control code to switch into non-FIPS mode.
- New cipher modes SIV and GCM-SIV as specified by RFC-5297.
- Extended cipher mode AESWRAP with padding as specified by
- New set of KDF functions.
- New KDF modes Argon2 and Balloon.
- New functions for combining hashing and signing/verification. [T4894]
- Improved support for PowerPC architectures.
- Improved ECC performance on zSeries/s390x by using accelerated
- Many more assembler performance improvements for several
* Bug fixes:
- Fix Elgamal encryption for other implementations.
- Fix alignment problem on macOS. [T5440]
- Check the input length of the point in ECDH. [T5423]
- Fix an abort in gcry_pk_get_param for "Curve25519". [T5490]
- Fix minor memory leaks in FIPS mode.
- Build fixes for MUSL libc. [rCffaef0be61]
* Other features:
- The control code GCRYCTL_SET_ENFORCED_FIPS_FLAG is ignored
because it is useless with the FIPS 140-3 related changes.
- Update of the jitter entropy RNG code. [T5523]
- Simplification of the entropy gatherer when using the getentropy
- More portable integrity check in FIPS mode. [rC9fa4c8946a,T5835]
- Add X9.62 OIDs to sha256 and sha512 modules. [rC52fd2305ba]
Note that 1.10.0 was already released on 2022-02-01 without a public
announcement to allow for some extra test time.

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-1.10.1.tar.bz2 you would use this
gpg --verify libgcrypt-1.10.1.tar.bz2.sig libgcrypt-1.10.1.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-1.10.1.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 has mostly been 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.
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 trademark
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*
