- Update to 3.4.1 release
* Fix CVE-2018-16869 (bsc#1118086)
All functions using RSA private keys are now side-channel
silent, meaning that they try hard to avoid any branches or
memory accesses depending on secret data. This applies both to
the bignum calculations, which now use GMP's mpn_sec_* family
of functions, and the processing of PKCS#1 padding needed for
RSA decryption.
* Changes in behavior:
The functions rsa_decrypt and rsa_decrypt_tr may now clobber
all of the provided message buffer, independent of the
actual message length. They are side-channel silent, in that
branches and memory accesses don't depend on the validity or
length of the message. Side-channel leakage from the
caller's use of length and return value may still provide an
oracle useable for a Bleichenbacher-style chosen ciphertext
attack. Which is why the new function rsa_sec_decrypt is
recommended.
* New features:
A new function rsa_sec_decrypt.
* Bug fixes:
- Fix bug in pkcs1-conv, missing break statements in the
parsing of PEM input files.
- Fix link error on the pss-mgf1-test test, affecting builds
without public key support.

the "_tr" suffix, with better resistance to side channel
attacks and to hardware or software failures which could
break the CRT optimization
* SHA3 implementation is updated according to the FIPS 202 standard
* New ARM Neon implementation of the chacha stream cipher

* Support for the GOST R 34.11-94 hash algorithm
* Support for SHA3
* Support for PKCS #5 PBKDF2
* Fixed a small memory leak in nettle_realloc and
nettle_xrealloc.
* x86_64 assembly for SHA256, SHA512, and SHA3
* ARM assembly code for several additional algorithms,
including AES, Salsa20, and the SHA family of hash
functions.
* Support for 12-round salsa20, "salsa20r12", as specified by
eSTREAM.
* Support for UMAC, including x86_64 and ARM assembly.
* Support for ECDSA signatures. Elliptic curve operations over
the following curves: secp192r1, secp224r1, secp256r1,
secp384r1 and secp521r1, including x86_64 and ARM assembly
for the most important primitives.
- Depend on makeinfo for info file generation.
- Don't disable static libs, they are needed at build time.
