<h1>1 Crypto Release Notes</h1>
<p>This document describes the changes made to the Crypto application.</p>
<h3><a name="id2252920">1.1
Crypto 1.6.4</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>Cross compilation improvements and other build system
improvements.</p>
<p>Most notable:</p> <ul>
<li> 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 <span class="code">$ERL_TOP/INSTALL-CROSS.md</span> file.
</li>
<li> Support for staged install using <span class="bold_code"><a href="http://www.gnu.org/prep/standards/html_node/DESTDIR.html">DESTDIR</a></span>.
The old broken <span class="code">INSTALL_PREFIX</span> has also been fixed.
For more information see the <span class="code">$ERL_TOP/INSTALL.md</span>
file. </li>
<li> Documentation of the <span class="code">release</span>
target of the top <span class="code">Makefile</span>. For more information
see the <span class="code">$ERL_TOP/INSTALL.md</span> file. </li>
<li>
<span class="code">make install</span> now by default creates relative
symbolic links instead of absolute ones. For more
information see the <span class="code">$ERL_TOP/INSTALL.md</span> file.
</li>
<li> <span class="code">$ERL_TOP/configure --help=recursive</span>
now works and prints help for all applications with
<span class="code">configure</span> scripts. </li>
<li> Doing <span class="code">make
install</span>, or <span class="code">make release</span> directly after
<span class="code">make all</span> no longer triggers miscellaneous
rebuilds. </li>
<li> Existing bootstrap system is now
used when doing <span class="code">make install</span>, or <span class="code">make
release</span> without a preceding <span class="code">make all</span>.
</li>
<li> The <span class="code">crypto</span> and <span class="code">ssl</span>
applications use the same runtime library path when
dynamically linking against <span class="code">libssl.so</span> and
<span class="code">libcrypto.so</span>. The runtime library search path has
also been extended. </li>
<li> The <span class="code">configure</span>
scripts of <span class="code">erl_interface</span> and <span class="code">odbc</span> now
search for thread libraries and thread library quirks the
same way as <span class="code">erts</span> do. </li>
<li> The
<span class="code">configure</span> script of the <span class="code">odbc</span> application
now also looks for odbc libraries in <span class="code">lib64</span> and
<span class="code">lib/64</span> directories when building on a 64-bit
system. </li>
<li> The <span class="code">config.h.in</span> file in the
<span class="code">erl_interface</span> application is now automatically
generated in instead of statically updated which reduces
the risk of <span class="code">configure</span> tests without any effect.
</li>
</ul>
<p>(Thanks to Henrik Riomar for suggestions and
testing)</p>
<p>(Thanks to Winston Smith for the AVR32-Linux cross
configuration and testing)</p>
<p>
*** POTENTIAL INCOMPATIBILITY ***</p>
<p>
Own Id: OTP-8323</p>
</li>
<li>
<p>
The crypto module now supports Blowfish in ECB, CBC and
OFB modes. (Thanks to Paul Oliver.)</p>
<p>
Own Id: OTP-8331</p>
</li>
<li>
<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>

visible change is that the frames are removed.</p>
<p>
Own Id: OTP-8201</p>
</li>
<li>
<p>
When the crypto application failed to load the
OpenSSL/LibEAY shared object, error indication was
sparse. Now a more specific error message is sent to the
error logger.</p>

<h3><a name="id2258844">1.9
Crypto 1.5.1.1</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>The linked in driver for the crypto application is now

<p>*** POTENTIAL INCOMPATIBILITY ***</p>
<p>Own Id: OTP-5631</p>
</li>
</ul>
<h3><a name="id2258984">1.12
Crypto 1.3</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>Added support for RFC 3826 - The Advanced Encryption Standard

<br>
Martin Björklund</p>
</li>
</ul>
<h3><a name="id2259018">1.13
Crypto 1.2.3</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<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>Own Id: OTP-5346</p>
</li>
</ul>
<h3><a name="id2259070">1.14
Crypto 1.2.2</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<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>Own Id: OTP-5279</p>
</li>
</ul>
<h3><a name="id2257212">1.15
Crypto 1.2.1</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<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>
<p>Own Id: OTP-4828 Aux Id: seq8193 </p>
</li>
</ul>
<h3><a name="id2257252">1.16
Crypto 1.2</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<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 <span class="code">libcrypto.so</span> (Unix)
or <span class="code">libeay32.[lib|dll]</span> (Win32). For further details
see the crypto(6) application manual page.</p>
</li>
<li>
<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>
</li>
<li>The functions <span class="code">des_ede3_cbc_encrypt/5</span> and
<span class="code">des_ede3_cbc_decrypt/5</span> have been renamed to
<span class="code">des3_cbc_encrypt/5</span> and <span class="code">des3_cbc_decrypt/5</span>,
respectively. The old functions have been retained (they are
deprecated and not listed in the crypto(3) manual page).</li>
</ul>
<h4>Reported Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>The start of crypto failed on Windows, due to erroneous addition
of a DES3 algorithm.</p>
<p>Own Id: OTP-4684
<br>
Aux Id: seq7864</p>
</li>
</ul>
<h3><a name="id2257356">1.17
Crypto 1.1.3</a></h3>
<h4>Reported Fixed Bugs and Malfunctions</h4>
<ul>
<li>To obtain backward compatibility with the old SSLeay
package, and with earlier versions of OpenSSL, the macro
OPENSSL_DES_LIBDES_COMPATIBILITY has been added to
<span class="code">crypto_drv.c</span>. This is of importance only for the open
source version of Crypto.
</li>
</ul>
<h3><a name="id2257388">1.18
Crypto 1.1.2</a></h3>
<h4>Reported Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>In the manual page <span class="code">crypto(3)</span> the function names
<span class="code">md5_finish</span> and <span class="code">sha_finish</span> have been changed to
<span class="code">md5_final</span> and <span class="code">sha_final</span> to correctly document
the implementation.</p>
<p>Own Id: OTP-3409
</p>
</li>
</ul>
<h3><a name="id2257441">1.19
Crypto 1.1.1</a></h3>
<p>Code replacement in runtime is supported. Upgrade can be done from
from version 1.1 and downgrade to version 1.1.
</p>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>The driver part of the Crypto application has been
updated to use the erl_driver header file. Version 1.1.1
requires emulator version 4.9.1 or later.</p>
</li>
</ul>
<h3><a name="id2257479">1.20
Crypto 1.1</a></h3>
<h4>Reported Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>On Windows the crypto_drv was incorrectly linked to
static run-time libraries instead of dynamic ones.</p>
<p>Own Id: OTP-3240
</p>
</li>
</ul>
<h3><a name="id2257513">1.21
Crypto 1.0</a></h3>
<p>New application.
