ANNOUNCE: Nettle-2.5
by nisse＠lysator.liu.se 07 Jul '12

07 Jul '12

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 Available at http://www.lysator.liu.se/~nisse/archive/nettle-2.5.tar.gz ftp://ftp.gnu.org/gnu/nettle/nettle-2.5.tar.gz and soon also at ftp://ftp.lysator.liu.se/pub/security/lsh/nettle-2.5.tar.gz Happy hacking, /Niels Möller -- Niels Möller.

Final nettle-2.5 prerelease
by nisse＠lysator.liu.se 06 Jul '12

I think everything's in shape for release. But I'll postpone the formal release to an evening *before* having a glass or two of wine. ;-) So here's a final prerelease http://www.lysator.liu.se/~nisse/archive/nettle-2.5-pre2.tar.gz http://www.lysator.liu.se/~nisse/archive/nettle-2.5-pre2.tar.gz.sig Hopefully the 2.5 release will differ in filename only.

I've done some documentatiion for Salsa20, so we're getting closer to release. See http://www.lysator.liu.se/~nisse/nettle/plan.html. NEWS-file review and some more testing remains on the list.

Using alloca on windows
by nisse＠lysator.liu.se 03 Jul '12

03 Jul '12

When I try cross-compiling using ./configure '--host=i586-mingw32msvc' I get warnings on alloca usage, e.g., /home/nisse/hack/nettle/cbc.c: In function `nettle_cbc_decrypt': /home/nisse/hack/nettle/cbc.c:101: warning: implicit declaration of function `alloca' /home/nisse/hack/nettle/cbc.c:101: warning: incompatible implicit declaration of built-in function `alloca' Which header should I include to get a proper declaration? In config.h, I have some boilerplate code which includes malloc.h, but only if *not* using gcc. Should I always include malloc.h if it exists, regardless of the compiler used?
