I'm happy to announce a new release of GNU Nettle, a low-level
cryptographics library. This is mainly a bug fix release, with few new

The Nettle home page can be found at, and the manual at

NEWS for the Nettle 3.2 release

        Bug fixes:

        * The SHA3 implementation is updated according to the FIPS 202
          standard. It is not interoperable with earlier versions of
          Nettle. Thanks to Nikos Mavrogiannopoulos. To easily
          differentiate at compile time, sha3.h defines the constant

        * Fix corner-case carry propagation bugs affecting elliptic
          curve operations on the curves secp_256r1 and secp_384r1 on
          certain platforms, including x86_64. Reported by Hanno Böck.

        New features:

        * New functions for RSA private key operations, identified by
          the "_tr" suffix, with better resistance to side channel
          attacks and to hardware or software failures which could
          break the CRT optimization. See the Nettle manual for
          details. Initial patch by Nikos Mavrogiannopoulos.

        * New functions nettle_version_major, nettle_version_minor, as
          a run-time variant of the compile-time constants


        * New ARM Neon implementation of the chacha stream cipher.


        * ABI detection on mips, with improved default libdir
          location. Contributed by Klaus Ziegler.

        * Fixes for ARM assembly syntax, to work better with the clang
          assembler. Thanks to Jukka Ukkonen.

        * Disabled use of ifunc relocations for fat builds, to fix
          problems most easily triggered by using dlopen RTLD_NOW.

        The shared library names are and, with sonames still and It is intended to be fully binary compatible
        with nettle-3.1.

Happy hacking,
