[gnutls-devel] gnutls 3.2.0

[Nikos Mavrogiannopoulos]

Hello,
 I've just released gnutls 3.2.0. This release significantly
improves the performance of gnutls in two ways. The new elliptic curve
implementation of nettle 2.7 is used which improves performance by a
factor of 2 (thanks to Niels Moeller), and on the ciphersuite level
the (currently) private ciphersuites with Salsa20 and UMAC-96 are
defined, giving a performance boost compared to any ARCFOUR or AES 
based ciphersuites. The new ciphersuites also provide a solution to the
recent attacks in TLS that compromise the security of CBC-based
ciphersuites and ARCFOUR. Note that since these are private --i.e.,
gnutls-specific-- ciphersuites they are not enabled by default.

In addition on this release all support for the so-called EXPORT
ciphersuites is dropped.


* Version 3.2.0 (released 2013-05-10)

** libgnutls: Use nettle's elliptic curve implementation.

** libgnutls: Added Salsa20 cipher

** libgnutls: Added UMAC-96 and UMAC-128

** libgnutls: Added ciphersuites involving Salsa20 and UMAC-96.
As they are not standardized they are defined using private ciphersuite 
numbers.

** libgnutls: Added support for DTLS 1.2.

** libgnutls: Added support for the Application Layer Protocol
Negotiation (ALPN) extension.

** libgnutls: Removed support for the RSA-EXPORT ciphersuites.

** libgnutls: Avoid linking to librt (that also avoids unnecessary
linking to pthreads if p11-kit isn't used).

** API and ABI modifications:
gnutls_cipher_get_iv_size: Added
gnutls_hmac_set_nonce: Added
gnutls_mac_get_nonce_size: Added
