<item>
<p>
Fix fatal bug when using a hmac context variable in more
than one call to <c>hmac_update</c> or <c>hmac_final</c>.
The reuse of hmac contexts has never worked as the
underlying OpenSSL implementation does not support it. It
is now documented as having undefined behaviour, but it
does not crash or corrupt the VM anymore.</p>

percept, public_key, reltool, runtime_tools, ssh,
syntax_tools, test_server, tools, typer, webtool, wx,
xmerl</c></p>
<p>

test_server. This is now used by most applications in
OTP.</p>

By giving --enable-static-{nifs,drivers} to configure it
is now possible to statically linking of nifs and drivers
to the main Erlang VM binary. At the moment only the asn1
and crypto nifs of the Erlang/OTP nifs and drivers have
been prepared to be statically linked. For more details

<section><title>Crypto 3.0</title>
<section><title>Improvements and New Features</title>
<list>
<item>
<p>
Integrate elliptic curve contribution from Andreas
Schultz </p>
<p>
In order to be able to support elliptic curve cipher
suites in SSL/TLS, additions to handle elliptic curve
infrastructure has been added to public_key and crypto.</p>
<p>
This also has resulted in a rewrite of the crypto API to
gain consistency and remove unnecessary overhead. All OTP
applications using crypto has been updated to use the new
API.</p>
<p>
Impact: Elliptic curve cryptography (ECC) offers
equivalent security with smaller key sizes than other
public key algorithms. Smaller key sizes result in
savings for power, memory, bandwidth, and computational
cost that make ECC especially attractive for constrained
environments.</p>

<p>
Make the crypto functions interruptible by chunking input
when it is very large and bumping reductions in the nifs.</p>
<p>
Not yet implemented for block_encrypt|decrypt/4</p>
<p>
Impact: Individual calls to crypto functions may take
longer time but over all system performance should
improve as crypto calls will not become throughput
bottlenecks.</p>

<p>
Due to standard library DLL mismatches between versions
of OpenSSL and Erlang/OTP, OpenSSL is now linked
statically to the crypto driver on Windows. This fixes
problems starting crypto when running Erlang as a service
on all Windows versions.</p>

<p>Cross compilation improvements and other build system
improvements.</p>
<p>Most notable:</p> <list><item> Lots of cross
compilation improvements. The old cross compilation
support was more or less non-existing as well as broken.
Please, note that the cross compilation support should
still be considered as experimental. Also note that old
cross compilation configurations cannot be used without
modifications. For more information on cross compiling
Erlang/OTP see the <c>$ERL_TOP/INSTALL-CROSS.md</c> file.
</item><item> Support for staged install using <url
href="http://www.gnu.org/prep/standards/html_node/DESTDIR.html">DESTDIR</url>.
The old broken <c>INSTALL_PREFIX</c> has also been fixed.
For more information see the <c>$ERL_TOP/INSTALL.md</c>
file. </item><item> Documentation of the <c>release</c>
target of the top <c>Makefile</c>. For more information
see the <c>$ERL_TOP/INSTALL.md</c> file. </item><item>
<c>make install</c> now by default creates relative
symbolic links instead of absolute ones. For more
information see the <c>$ERL_TOP/INSTALL.md</c> file.
</item><item> <c>$ERL_TOP/configure --help=recursive</c>
now works and prints help for all applications with
<c>configure</c> scripts. </item><item> Doing <c>make
install</c>, or <c>make release</c> directly after
<c>make all</c> no longer triggers miscellaneous
rebuilds. </item><item> Existing bootstrap system is now
used when doing <c>make install</c>, or <c>make
release</c> without a preceding <c>make all</c>.
</item><item> The <c>crypto</c> and <c>ssl</c>
applications use the same runtime library path when
dynamically linking against <c>libssl.so</c> and
<c>libcrypto.so</c>. The runtime library search path has
also been extended. </item><item> The <c>configure</c>
scripts of <c>erl_interface</c> and <c>odbc</c> now
search for thread libraries and thread library quirks the
same way as <c>erts</c> do. </item><item> The
<c>configure</c> script of the <c>odbc</c> application
now also looks for odbc libraries in <c>lib64</c> and
<c>lib/64</c> directories when building on a 64-bit
system. </item><item> The <c>config.h.in</c> file in the
<c>erl_interface</c> application is now automatically
generated in instead of statically updated which reduces
the risk of <c>configure</c> tests without any effect.
</item></list>

testing)</p>

</item>
<item>
<p>The documentation is now possible to build in an open
source environment after a number of bugs are fixed and
some features are added in the documentation build
process. </p>
<p>- The arity calculation is updated.</p>
<p>- The module prefix used in the function names for
bif's are removed in the generated links so the links
will look like
"http://www.erlang.org/doc/man/erlang.html#append_element-2"
instead of
"http://www.erlang.org/doc/man/erlang.html#erlang:append_element-2".</p>
<p>- Enhanced the menu positioning in the html
documentation when a new page is loaded.</p>
<p>- A number of corrections in the generation of man
pages (thanks to Sergei Golovan)</p>
<p>- The legal notice is taken from the xml book file so
OTP's build process can be used for non OTP
applications.</p>

<p>The linked in driver for the crypto application is now
linked statically against the OpenSSL libraries, to avoid
installation and runtime problems in connection to the
OpenSSL library locations.</p>

<p>The previously undocumented and UNSUPPORTED <c>ssh</c>
application has been updated and documented. This release
of the <c>ssh</c> application is still considered to be a
beta release and (if necessary) there could still be
changes in its API before it reaches 1.0.</p>
<p>Also, more cryptographic algorithms have been added to
the <c>crypto</c> application.</p>

<p>Linked in drivers in the crypto, and asn1 applications
are now compiled with the -D_THREAD_SAFE and -D_REENTRANT
switches on unix when the emulator has thread support
enabled.</p>
<p>Linked in drivers on MacOSX are not compiled with the
undocumented -lbundle1.o switch anymore. Thanks to Sean
Hinde who sent us a patch.</p>
<p>Linked in driver in crypto, and port programs in ssl, now
compiles on OSF1.</p>
<p>Minor makefile improvements in runtime_tools.</p>

<p>Corrected error handling. If the port to the driver that
crypto uses is unexpectedly closed (which should not
happen during normal operation of crypto), crypto will
terminate immediately (rather than crashing the next time
crypto is used). Also corrected build problems on Mac OS
X.</p>

<p>It was not possible in R9 to relink the crypto driver.
The object file was missing as well as an example
makefile. The crypto driver object file is now released
with the application (installed in priv/obj). An example
makefile has also been added to the priv/obj directory.
The makefile serves as an example of how to relink the
driver on Unix (crypto_drv.so) or Windows
(crypto_drv.dll).</p>

<title>Improvements and New Features</title>
<list type="bulleted">
<item>
<p>Previous versions of Crypto where delivered with
statically linked binaries based on SSLeay. That is not
longer the case. The current version of Crypto requires
dynamically linked OpenSSL libraries that the user has to
install. The library needed is <c>libcrypto.so</c> (Unix)
or <c>libeay32.[lib|dll]</c> (Win32). For further details
see the crypto(6) application manual page.</p>
</item>
<item>
<p>This version of Crypto uses the new DES interface of
OpenSSL 0.9.7, which is not backward compatible with
earlier versions of OpenSSL.
</p>
</item>
<item>The functions <c>des_ede3_cbc_encrypt/5</c> and
<c>des_ede3_cbc_decrypt/5</c> have been renamed to
<c>des3_cbc_encrypt/5</c> and <c>des3_cbc_decrypt/5</c>,
respectively. The old functions have been retained (they are
deprecated and not listed in the crypto(3) manual page).</item>

<item>To obtain backward compatibility with the old SSLeay

OPENSSL_DES_LIBDES_COMPATIBILITY has been added to
<c>crypto_drv.c</c>. This is of importance only for the open
