Correction of the word 'ChipherText' throughout the documentation (Thanks to Andrew Tunnell-Jones)

Own Id: OTP-11609

Fix fatal bug when using a hmac context variable in more than one call to hmac_update or hmac_final. 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.

Own Id: OTP-11724

Crypto handles out-of-memory with a controlled abort instead of crash/corruption. (Thanks to Florian Zumbiehi)

Own Id: OTP-11725

Application upgrade (appup) files are corrected for the following applications:

asn1, common_test, compiler, crypto, debugger, dialyzer, edoc, eldap, erl_docgen, et, eunit, gs, hipe, inets, observer, odbc, os_mon, otp_mibs, parsetools, percept, public_key, reltool, runtime_tools, ssh, syntax_tools, test_server, tools, typer, webtool, wx, xmerl

A new test utility for testing appup files is added to test_server. This is now used by most applications in OTP.

(Thanks to Tobias Schlager)

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.

Own Id: OTP-11009

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

Own Id: OTP-11058

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.

RC4 stream cipher didn't work. This since the new NIF implementation of crypto:rc4_encrypt_with_state/2 introduced in crypto-2.0 didn't return an updated state. (Thanks to Paul Guyot)

Own Id: OTP-8781

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

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.

Own Id: OTP-8343

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.

Own Id: OTP-8201

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.

./configure has been improved to find 64-bit OpenSSL libraries.

Own Id: OTP-7270

crypto and zlib drivers improved to allow concurent smp access.

Own Id: OTP-7262

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.

Own Id: OTP-6680

Minor Makefile changes.

Own Id: OTP-6689

It is now explicitly checked at start-up that the crypto driver is properly loaded (Thanks to Claes Wikstrom).

Own Id: OTP-6109

The previously undocumented and UNSUPPORTED ssh application has been updated and documented. This release of the ssh 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.

Also, more cryptographic algorithms have been added to the crypto application.

*** POTENTIAL INCOMPATIBILITY ***

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).

Own Id: OTP-4828 Aux Id: seq8193

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 libcrypto.so (Unix) or libeay32.[lib|dll] (Win32). For further details see the crypto(6) application manual page.

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.

Aux Id: seq7864

In the manual page crypto(3) the function names md5_finish and sha_finish have been changed to md5_final and sha_final to correctly document the implementation.

Own Id: OTP-3409

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.
