This document describes the changes made to the Crypto application.
Refactor ecdsa cipher to simplify code and improve performance.

Integrate elliptic curve contribution from Andreas Schultz
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.
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.
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.

Fixed a spelling mistake in crypto docs. Thanks to Klaus Trainer

Make the crypto functions interruptible by chunking input when it is very large and bumping reductions in the nifs.
Not yet implemented for block_encrypt|decrypt/4
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.

Remove unnecessary dependency to libssl from crypto NIF library. This dependency was introduced by accident in R14B04.
Own Id: OTP-10064
Add crypto and public_key support for the hash functions SHA224, SHA256, SHA384 and SHA512 and also hmac and rsa_sign/verify support using these hash functions. Thanks to Andreas Schultz for making a prototype.

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.

A number of memory leaks in the crypto NIF library have been fixed.
Own Id: OTP-8810
Added erlang:system_info(build_type) which makes it easier to chose drivers, NIF libraries, etc based on build type of the runtime system.
The NIF library for crypto can now be built for valgrind and/or debug as separate NIF libraries that will be automatically loaded if the runtime system has been built with a matching build type.
Own Id: OTP-8760
crypto application changed to use NIFs instead of driver.
Own Id: OTP-8333
des_ecb_encrypt/2 and des_ecb_decrypt/2 has been added to the crypto module. The crypto:md4/1 function has been documented.

The crypto module now supports Blowfish in ECB, CBC and OFB modes. (Thanks to Paul Oliver.)
Own Id: OTP-8331
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.
- The arity calculation is updated.
- 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".
- Enhanced the menu positioning in the html documentation when a new page is loaded.
- A number of corrections in the generation of man pages (thanks to Sergei Golovan)
- The legal notice is taken from the xml book file so OTP's build process can be used for non OTP applications.

Suppressed false valgrind errors caused by libcrypto using uninitialized data as entropy.
Own Id: OTP-8200
The documentation is now built with open source tools (xsltproc and fop) that exists on most platforms. One visible change is that the frames are removed.

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.

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.
Linked in drivers on MacOSX are not compiled with the undocumented -lbundle1.o switch anymore. Thanks to Sean Hinde who sent us a patch.
Linked in driver in crypto, and port programs in ssl, now compiles on OSF1.
Minor makefile improvements in runtime_tools.
Own Id: OTP-5346
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.
Own Id: OTP-5279
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).

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
This version of Crypto uses the new DES interface of OpenSSL 0.9.7, which is not backward compatible with earlier versions of OpenSSL.
The start of crypto failed on Windows, due to erroneous addition of a DES3 algorithm.

Code replacement in runtime is supported. Upgrade can be done from from version 1.1 and downgrade to version 1.1.
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.
On Windows the crypto_drv was incorrectly linked to static run-time libraries instead of dynamic ones.
