- update to 3.8:
This release includes a couple of new features, and many
performance improvements. It adds assembly code for two more
architectures: ARM64 and S390x.
The new version is intended to be fully source and binary
compatible with Nettle-3.6. The shared library names are
libnettle.so.8.5 and libhogweed.so.6.5, with sonames
libnettle.so.8 and libhogweed.so.6.
New features:
* AES keywrap (RFC 3394), contributed by Nicolas Mora.
* SM3 hash function, contributed by Tianjia Zhang.
* New functions cbc_aes128_encrypt, cbc_aes192_encrypt,
cbc_aes256_encrypt.
On processors where AES is fast enough, e.g., x86_64 with
aesni instructions, the overhead of using Nettle's general
cbc_encrypt can be significant. The new functions can be
implemented in assembly, to do multiple blocks with reduced
per-block overhead.
Note that there's no corresponding new decrypt functions,
since the general cbc_decrypt doesn't suffer from the same
performance problem.
Bug fixes:
* Fix fat builds for x86_64 windows, these appear to never
have worked.
Optimizations:
* New ARM64 implementation of AES, GCM, Chacha, SHA1 and
SHA256, for processors supporting crypto extensions. Great
speedups, and fat builds are supported. Contributed by
Mamone Tarsha.
* New s390x implementation of AES, GCM, Chacha, memxor, SHA1,
