Gmane
From: Nikos Mavrogiannopoulos <nmav <at> gnutls.org>
Subject: gnutls 3.3.0
Newsgroups: gmane.comp.encryption.gpg.gnutls.devel
Date: Thursday 10th April 2014 18:28:38 UTC (over 3 years ago)
We are proud to announce the next stable GnuTLS release: Version 3.3.0.

GnuTLS is a modern C library that implements the standard network
security protocol Transport Layer Security (TLS), for use by network
applications.  GnuTLS is developed for GNU/Linux, but works on many
Unix-like systems and Windows.

The GnuTLS library is distributed under the terms of the GNU Lesser
General Public License version 2 (or later).  The OpenSSL compatibility
library, the self tests and the command line tools are all distributed
under the GNU General Public License version 3.0 (or later).  The manual
is distributed under the GNU Free Documentation License version 1.3 (or
later).

Special thanks to Red Hat that sponsored several of the new features.

The project page of the library is available at:
  http://www.gnutls.org


What's New
==========
* Version 3.3.0 (released 2014-04-10)

** libgnutls: The initialization of the library was moved to a
constructor. That is, gnutls_global_init() is no longer required
unless linking with a static library or a system that does not
support library constructors.

** libgnutls: static libraries are not built by default.

** libgnutls: PKCS #11 initialization is delayed to first usage.
That avoids long delays in gnutls initialization due to broken PKCS #11
modules.

** libgnutls: The PKCS #11 subsystem is re-initialized "automatically"
on the first PKCS #11 API call after a fork. 

** libgnutls: certificate verification profiles were introduced
that can be specified as flags to verification functions. They
are enumerations in gnutls_certificate_verification_profiles_t
and can be converted to flags for use in a verification function
using GNUTLS_PROFILE_TO_VFLAGS().

** libgnutls: Added the ability to read system-specific initial
keywords, if they are prefixed with '@'. That allows a compile-time
specified configuration file to be used to read pre-configured priority
strings from. That can be used to impose system specific policies.

** libgnutls: Increased the default security level of priority
strings (NORMAL and PFS strings require at minimum a 1008 DH prime), 
and set a verification profile by default.  The LEGACY keyword is 
introduced to set the old defaults.

** libgnutls: Added support for the name constraints PKIX extension.
Currently only DNS names and e-mails are supported (no URIs, IPs
or DNs).

** libgnutls: Security parameter SEC_PARAM_NORMAL was renamed to 
SEC_PARAM_MEDIUM to avoid confusion with the priority string NORMAL.

** libgnutls: Added new API in x509-ext.h to handle X.509 extensions.
This API handles the X.509 extensions in isolation, allowing to parse
similarly formatted extensions stored in other structures.

** libgnutls: When generating DSA keys the macro GNUTLS_SUBGROUP_TO_BITS
can be used to specify a particular subgroup as the number of bits in
gnutls_privkey_generate; e.g., GNUTLS_SUBGROUP_TO_BITS(2048, 256).

** libgnutls: DH parameter generation is now delegated to nettle.
That unfortunately has the side-effect that DH parameters longer than
3072 bits, cannot be generated (not without a nettle update).

** libgnutls: Separated nonce RNG from the main RNG. The nonce
random number generator is based on salsa20/12.

** libgnutls: The buffer alignment provided to crypto backend is
enforced to be 16-byte aligned, when compiled with cryptodev
support. That allows certain cryptodev drivers to operate more
efficiently.

** libgnutls: Return error when a public/private key pair that doesn't
match is set into a credentials structure.

** libgnutls: Depend on p11-kit 0.20.0 or later.

** libgnutls: The new padding (%NEW_PADDING) experimental TLS extension
has been removed. It was not approved by IETF.

** libgnutls: The experimental xssl library is removed from the gnutls
distribution.

** libgnutls: Reduced the number of gnulib modules used in the main
library.

** libgnutls: Added priority string %DISABLE_WILDCARDS.

** libgnutls: Added the more extensible verification function
gnutls_certificate_verify_peers(), that allows checking, in addition
to a peer's DNS hostname, for the key purpose of the end certificate
(via PKIX extended key usage).

** certtool: Timestamps for serial numbers were increased to 8 bytes,
and in batch mode to 12 (appended with 4 random bytes).

** certtool: When no CRL number is provided (or value set to -1), then
a time-based number will be used, similarly to the serial generation
number in certificates.

** certtool: Print the SHA256 fingerprint of a certificate in addition
to SHA1.

** libgnutls: Added --enable-fips140-mode configuration option
(unsupported). That option enables (when running on FIPS140-enabled
system):
 o RSA, DSA and DH key generation as in FIPS-186-4 (using provable
primes)
 o The DRBG-CTR-AES256 deterministic random generator from SP800-90A.
 o Self-tests on initialization on ciphers/MACs, public key algorithms 
   and the random generator.
 o HMAC-SHA256 verification of the library on load.
 o MD5 is included for TLS purposes but cannot be used by the high level
   hashing functions.
 o All ciphers except AES are disabled.
 o All MACs and hashes except GCM and SHA are disabled (e.g., HMAC-MD5).
 o All keys (temporal and long term) are zeroized after use.
 o Security levels are adjusted to the FIPS140-2 recommendations (rather
   than ECRYPT).
