I'm happy to annnounce a new version of GNU Nettle, a low-level
cryptographics library. The Nettle home page can be found at
http://www.lysator.liu.se/~nisse/nettle/.

NEWS for the 2.5 release

	This release includes important portability fixes for Windows
	and MacOS. There are also a few new features.

	First a *warning*: Some internal functions have been removed
	from the library. Since the functions in question are internal
	and not documented, this is not considered a change of ABI or
	API. Programs explicitly using any of these functions will
	break.
	
	* The function pkcs1_signature_prefix has been renamed to
	  _pkcs1_signature_prefix, and with slightly different
	  behavior.

	* The file nettle-internal.c is no longer included in the
          library (the features defined there are used by the
          benchmark and test programs, and were never intended for
          public use).

	New features:

	* Support for the salsa20 block cipher, including x86_64
          assembler. Originally contributed by Simon Josefsson, based
          on the reference implementation, then further optimized.

	* Tentative interface for timing-resistant RSA functions,
          contributed by Nikos Mavrogiannopoulos.

	* A more general interface for PKCS#1 signatures, taking the
          input in the form of a "DigestInfo". Suggested by Nikos
          Mavrogiannopoulos.

	Configuration:
	
	* Building of shared libraries (./configure --enable-shared)
          is now enabled by default.

	* Various portability fixes for MacOS and M$ Windows. A lot of
	  this work done by Martin Storsjö.

	* In particular, Nettle now hopefully works on 64-bit Windows
	  builds, "W64", including the x86_64 assembly code.

	Miscellaneous:
	
	* Documentation and example programs for the base16 and base64
	  functions. Was contributed by Jeronimo Pellegrini back in
	  2006, but unfortunately forgotten until now.

	* Use an additional table to avoid GF2^8 multiplications in
	  aes_invert_key (mainly used by aes_set_decrypt_key). Also
	  tabulate round constants in aes_set_encrypt_key.

	* The nettle repository has been migrated from cvs to git,
	  with a public repository at
	  http://git.lysator.liu.se/nettle. To make it independent of
	  the LSH repository, a few files have been moved around.
	  While at it, files have also been converted from latin-1 to
	  utf-8.

	The libraries are intended to be binary compatible with
	nettle-2.2 and later. The shared library names are
	libnettle.so.4.4 and libhogweed.so.2.2, with sonames still
	libnettle.so.4 and libhogweed.so.2
