ANNOUNCE: Nettle-2.2

[Niels Möller]

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.
