Some other smaller changes that are not + backwards compatible are also done at the same time. + + * The nettle library is split into two libraries, libnettle + and libhogweed. libnettle contains the symmetric crypto + algorithms that don't depend on GMP, while libhogweed + contains the public key algorithms that depend on GMP. + Using a single library worked fine with static linking, but + not with dynamic linking. Consider an application that uses + nettle and which doesn't use any public key cryptography. If + this application is linked dynamically to nettle, it would + have to be linked also with GMP if and only if public key + support was enabled when the nettle library was installed. + + The library names are libnettle.so.3.0 and + libhogweed.so.1.0, with sonames libnettle.so.3 and + libhogweed.so.1. + + * Function typedefs have been changed to non-pointer types. + E.g, the + + typedef void (nettle_hash_init_func *)(void *ctx); + + of previous versions is replaced by + + typedef void (nettle_hash_init_func)(void *ctx); + + This makes it possible to use the type when declaring + functions, like + + nettle_hash_init_func foo_hash_init; + + void foo_hash_init(void *ctx) { ... } + + * Changes to the yarrow256 interface. The automatic seed file + generation, and the seed_file member in struct + yarrow256_ctx, has been removed. To generate a new seed + file, use yarrow256_random. The function + yarrow256_force_reseed has been replaced by the two + functions yarrow256_fast_reseed and yarrow256_slow_reseed, + which were previously static. This interface change makes it + easier to mix in the current content of the seed file before + overwriting it with newly generated data. + + Other changes: + + * The sexp-conv program preserves comments when using the + advanced syntax for output. Optionally locks the output + file. + + * The base64 decoder recognizes ASCII FF (form feed) and VT + (vertical tab) as white space. + + * New x86_64 implementations of AES and SHA1. On a 2.2 GHz + opteron, SHA1 was benchmarked at 250 MByte/s, and AES-128 at + 110 MByte/s. + + * Performance of AES increased by 20-30% on x86. + + * New programs in the examples directory: erathostenes and + next-prime. + NEWS for the 1.15 release Added support for PKCS#1 style RSA signatures using SHA256,
