<H2>1 Crypto Release Notes
</H2>
<P>This document describes the changes made to the Crypto application.
<A NAME="1.1"><!-- Empty --></A>
<H3>1.1 Crypto 1.5</H3>
<A NAME="1.1.1"><!-- Empty --></A>
<H4>1.1.1 Improvements and New Features</H4>
<P>
<UL>
<LI>
It is now explicitly checked at start-up that the crypto
driver is properly loaded (Thanks to Claes Wikstrom).
<BR>

</UL>
<A NAME="1.2"><!-- Empty --></A>
<H3>1.2 Crypto 1.4</H3>
<A NAME="1.2.1"><!-- Empty --></A>
<H4>1.2.1 Improvements and New Features</H4>
<P>
<UL>
<LI>
The previously undocumented and UNSUPPORTED <CODE>ssh</CODE>
application has been updated and documented. This release
of the <CODE>ssh</CODE> 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.
<BR>
Also, more cryptographic algorithms have been added to
the <CODE>crypto</CODE> application.
<BR>
*** POTENTIAL INCOMPATIBILITY ***

<A NAME="1.3"><!-- Empty --></A>
<H3>1.3 Crypto 1.3</H3>
<A NAME="1.3.1"><!-- Empty --></A>
<H4>1.3.1 Improvements and New Features</H4>
<P>
<UL>
<LI>
Added support for RFC 3826 - The Advanced Encryption Standard
(AES) Cipher Algorithm in the SNMP User-based Security Model.
<BR>

<A NAME="1.4"><!-- Empty --></A>
<H3>1.4 Crypto 1.2.3</H3>
<A NAME="1.4.1"><!-- Empty --></A>
<H4>1.4.1 Fixed Bugs and Malfunctions</H4>
<P>
<UL>
<LI>
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.
<BR>
Linked in drivers on MacOSX are not compiled with the
undocumented -lbundle1.o switch anymore. Thanks to Sean
Hinde who sent us a patch.
<BR>
Linked in driver in crypto, and port programs in ssl, now
compiles on OSF1.
<BR>
Minor makefile improvements in runtime_tools.
<BR>
Own Id: OTP-5346

<A NAME="1.5"><!-- Empty --></A>
<H3>1.5 Crypto 1.2.2</H3>
<A NAME="1.5.1"><!-- Empty --></A>
<H4>1.5.1 Improvements and New Features</H4>
<P>
<UL>
<LI>
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.
<BR>

<A NAME="1.6"><!-- Empty --></A>
<H3>1.6 Crypto 1.2.1</H3>
<A NAME="1.6.1"><!-- Empty --></A>
<H4>1.6.1 Fixed Bugs and Malfunctions</H4>
<P>
<UL>
<LI>
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).

<A NAME="1.7"><!-- Empty --></A>
<H3>1.7 Crypto 1.2</H3>
<A NAME="1.7.1"><!-- Empty --></A>
<H4>1.7.1 Improvements and New Features</H4>
<P>
<UL>
<LI>
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 <CODE>libcrypto.so</CODE> (Unix)
or <CODE>libeay32.[lib|dll]</CODE> (Win32). For further details
see the crypto(6) application manual page.
<BR>
</LI>
<LI>
This version of Crypto uses the new DES interface of
OpenSSL 0.9.7, which is not backward compatible with
earlier versions of OpenSSL.
<BR>
</LI>
<LI>
The functions <CODE>des_ede3_cbc_encrypt/5</CODE> and
<CODE>des_ede3_cbc_decrypt/5</CODE> have been renamed to
<CODE>des3_cbc_encrypt/5</CODE> and <CODE>des3_cbc_decrypt/5</CODE>,
respectively. The old functions have been retained (they are
deprecated and not listed in the crypto(3) manual page).
</LI>
</UL>
<A NAME="1.7.2"><!-- Empty --></A>
<H4>1.7.2 Reported Fixed Bugs and Malfunctions</H4>
<P>
<UL>
<LI>
The start of crypto failed on Windows, due to erroneous addition
of a DES3 algorithm.

<A NAME="1.8"><!-- Empty --></A>

<A NAME="1.8.1"><!-- Empty --></A>
<H4>1.8.1 Reported Fixed Bugs and Malfunctions</H4>
<P>
<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
<CODE>crypto_drv.c</CODE>. This is of importance only for the open
source version of Crypto.
</LI>
</UL>
<A NAME="1.9"><!-- Empty --></A>
<H3>1.9 Crypto 1.1.2</H3>
<A NAME="1.9.1"><!-- Empty --></A>
<H4>1.9.1 Reported Fixed Bugs and Malfunctions</H4>
<P>
<UL>
<LI>
In the manual page <CODE>crypto(3)</CODE> the function names
<CODE>md5_finish</CODE> and <CODE>sha_finish</CODE> have been changed to
<CODE>md5_final</CODE> and <CODE>sha_final</CODE> to correctly document
the implementation.
Own Id: OTP-3409
<BR>
</LI>
</UL>
<A NAME="1.10"><!-- Empty --></A>
<H3>1.10 Crypto 1.1.1</H3>
<P>Code replacement in runtime is supported. Upgrade can be done from
from version 1.1 and downgrade to version 1.1.
<A NAME="1.10.1"><!-- Empty --></A>
<H4>1.10.1 Improvements and New Features</H4>
<P>
<UL>
<LI>
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.
<BR>
</LI>
</UL>
<A NAME="1.11"><!-- Empty --></A>

<A NAME="1.11.1"><!-- Empty --></A>

On Windows the crypto_drv was incorrectly linked to
static run-time libraries instead of dynamic ones.
