I'm happy to announce a new version of GNU Nettle, a low-level
cryptographic library. Unlike earlier releases, nettle is now licenced
under the LGPL, rather then the GPL. The nettle home page can be found
at http://www.lysator.liu.se/~nisse/nettle/

NEWS for the 2.2 release

	Licensing change:
     	
	* Relicensed as LGPL v2.1 or later (user's option).

	* Replaced blowfish and serpent implementation. New code is
          based on the LGPLed code in libgcrypt.

	New features:

	* Support for Galois/Counter Mode (GCM).

	* New interface for enumerating (most) available algorithms,
	  contributed by Daniel Kahn Gillmor.

	* New tool nettle-hash. Can generate hash digests using any
	  supported hash function, with output compatible with md5sum
	  and friends from GNU coreutils. Checking (like md5sum -c)
	  not yet implemented.

	Bug fixes:

	* The old serpent code had a byte order bug (introduced by
	  yours truly about ten years ago). New serpent implementation
	  does not interoperate with earlier versions of nettle.

	* Fixed ABI-dependent libdir default for Linux-based systems
	  which do not follow the Linux File Hierarchy Standard, e.g.,
	  Debian GNU/Linux.

	Optimizations:
	
	* x86_64 implemention of serpent.

	* x86_64 implemention of camellia.

	* Optimized memxor using word rather than byte operations.
          Both generic C and x86_64 assembler.

	* Eliminated a memcpy for in-place CBC decrypt.
	
	Miscellaneous:

	* In command line tools, no longer support -? for requesting
          help, since using it without shell quoting is a dangerous
          habit. Use long option --help instead.

	The shared library names are libnettle.so.4.1 and
	libhogweed.so.2.1, with sonames libnettle.so.4 and
	libhogweed.so.2.

Happy hacking,
