<h1> Nettle release plans </h1>
<p> This is an attempt at defining a development target for
Nettle-2.5, inspired by similar pages for recent GMP releases. [Last
updated 2012-06-09]</p>
<p class='should'>
This really ought to be done before release
</p>
<p class='wish'>
Try to get this done before release
</p>
<p class='done'>
Done!
</p>
<p class='postponed'>
Leave for some later release!
</p>
<h1> Plan for the Nettle-2.5 release </h1>
<h2> RSA blinding </h2>
<p class='done'>
Add tentative interface, as suggested by Nikos. Don't try yet to
get blinding variants of <em>all</em> signature functions.
</p>
<h2> Documentation </h2>
<p class='done'>
Update documentation with info on Salsa20.
</p>
<p class='should'>
Update NEWS file.
</p>
<h2> Bug fixes </h2>
<p class='done'>
Various w64 fixes, mostly by Martin Storsjö.
</p>
<p class='done'>
Workaround for uint8_fast_t gnutls/gnulib incompatibilty on SunOS 5.8.
</p>
<h2> Other </h2>
<p class='done'> The interface of the internal function
<tt>pkcs1_signature_prefix</tt> has changed. Rename it to
<tt>_pkcs1_signature_prefix</tt>, to clearly mark it internal and
also make applications using it fail more predictably at compile or
link time.</p>
<h2> Testing </h2>
<p> Since xenofarm isn't up and running, do some manual testing:
</p>
<ul>
<li class='done'> x86_64-gnu-linux</li>
<li class='done'> x86_64-freebsd</li>
<li class='done'> x86-gnu-linux</li>
<li class='done'> x86-freebsd</li>
<li class='should'> x86-w*ndows (using cross compiler and wine)</li>
<li class='wish'> x86_64-w*ndows (seems a bit harder to get
mingw64 and wine64 working)</li>
<li class='done'> sparc32-solaris10</li>
<li class='done'> sparc64-solaris10</li>
</ul>
<h1> Plans for nettle-3.0 </h1>
<h2> Interface changes </h2>
<p class='should'>
Change the type of all lengths from <tt>unsigned</tt>
to <tt>size_t</tt>. An ABI change on most 64-bit platforms.
</p>
<p class='should'>
For Merkle-Damgaard hash functions, separate the state and the
buffering. E.g., when using them for HMAC keyed "inner" and
"outer" states, we now get three buffers but we only need one.
</p>
<p class='should'>
Use the nettle_cipher abstraction only for block ciphers (in
particular, exclude arcfour). Use a const for the ctx argument to
nettle_crypt_func.
</p>
<p class='wish'>
Consider making a public interface similar to nettle_aead? With
the above change, it can't use nettle_crypt_func.
</p>
<p class='wish'>
Make it possible to build nettle and hogweed using mini-gmp.
</p>
<p class='should'>
Reorganize private key operations. Need to support RSA with and
without blinding, and DSA according to spec and some deterministic
variant (like putty), and possibly also smartcard versions where
the private key is not available to the library. And without an
explosion of the number of functions.
