I'm happy to announce a new release of GNU Nettle, a low-level
cryptographics library. This release adds support for RSA-OAEP, and
improves performance mainly for powerpc64. See NEWS entries below.
The Nettle home page can be found at
https://www.lysator.liu.se/~nisse/nettle/, and the manual at
https://www.lysator.liu.se/~nisse/nettle/nettle.html.
The release can be downloaded from
https://ftp.gnu.org/gnu/nettle/nettle-3.10.tar.gz
https://www.lysator.liu.se/~nisse/archive/nettle-3.10.tar.gz
Happy hacking,

NEWS for the Nettle 3.10 release
This is a maintenance release, including a few each of bug
fixes, new features and optimizations.
The new version is intended to be fully source and binary
compatible with Nettle-3.6. The shared library names are
libnettle.so.8.9 and libhogweed.so.6.9, with sonames
libnettle.so.8 and libhogweed.so.6.
Bug fixes:
* Add missing hash functions sha512_224 and sha512_256 to the
nettle_get_hashes() list. The name values in the
corresponding nettle_hash structs also changed to use
underscore instead of dash, for consistency.
* Fix a few cases of formally undefined calls to memcpy(dst,
NULL, 0), resulting from valid calls to, e.g.,
sha256_update(ctx, 0, NULL).
New features:
* Support RSA-OAEP encryption. Contributed by Nicolas Mora and
Daiki Ueno.
* New function sha3_256_shake_output, new functions
sha3_128_init, sha3_128_update, sha3_128_shake,
sha3_128_shake_output. Contributed by Daiki Ueno.
* Added DRBG-CTR with AES256, contributed by Simon Josefsson.
Optimizations:
* New combined gcm-aes assembly for powerpc64, contributed by
Danny Tsen.
* New sha256 assembly for powerpc64, contributed by Eric
Richter.
* Improved performance for powerpc64 AES decrypt, by skipping
subkey transformations that don't suit the vncipher
instructions.
* Add arm64 CPU feature detection for Android and for Apple systems,
contributed by Foolbar and Tim Kosse, prespectively.
Miscellaneous:
* New tests for side-channel silence, based on valgrind.
* Delete all md5 assembly code. Delete all sparc32 assembly code.
