    Own Id: OTP-13951

1.6  Crypto 3.7.1

Fixed Bugs and Malfunctions

  • Crypto has been fixed to work against OpenSSL versions with disabled DES ciphers. Correct spelling of cipher algorithm 'des3_cfb' has been introduced; the previous misspeling still works.

    Own Id: OTP-13783 Aux Id: ERL-203

  • The size of an internal array in crypto has been fixed to not segfault when having all possible ciphers. Bug fix by Duncan Overbruck.

    Own Id: OTP-13789 Aux Id: PR-1140

    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

    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)

    Own Id: OTP-11744

Improvements and New Features

  • 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 see the Installation Guide in the System documentation.

    Own Id: OTP-11258

  • Add IGE mode for AES cipher in crypto (Thanks to Yura Beznos).

    Own Id: OTP-11522

  • Moved elliptic curve definition from the crypto NIF/OpenSSL into Erlang code, adds the RFC-5639 brainpool curves and makes TLS use them (RFC-7027).

    Own Id: OTP-11510

1.18  Crypto 3.1

Improvements and New Features

  • Refactor ecdsa cipher to simplify code and improve performance.

    Own Id: OTP-11320

1.19  Crypto 3.0

Improvements and New Features

  • 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

Known Bugs and Problems

  • 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.

    Own Id: OTP-11142

1.20  Crypto 2.3

Improvements and New Features

  • Enable runtime upgrade of crypto including the OpenSSL library used by crypto.

    Own Id: OTP-10596

    Own Id: OTP-9312

  • Erlang/OTP can now be built using parallel make if you limit the number of jobs, for instance using 'make -j6' or 'make -j10'. 'make -j' does not work at the moment because of some missing dependencies.

    Own Id: OTP-9451

  • Add DES and Triple DES cipher feedback (CFB) mode functions to crypto. (Thanks to Paul Guyot)

    Own Id: OTP-9640

  • Add sha256, sha384 and sha512 support for crypto:rsa_verify.

    Own Id: OTP-9778

1.23  Crypto 2.0.4

Fixed Bugs and Malfunctions

  • Crypto dialyzer type error in md5_mac and sha_mac.

    Own Id: OTP-8718

  • 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

Improvements and New Features

  • 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

1.29  Crypto 2.0

Improvements and New Features

  • crypto application changed to use NIFs instead of driver.

    Own Id: OTP-8333

    Own Id: OTP-8551

  • The undocumented, unsupport, and deprecated function lists:flat_length/1 has been removed.

    Own Id: OTP-8584

  • New variants of crypto:dss_sign and crypto:dss_verify with an extra argument to control how the digest is calculated.

    Own Id: OTP-8700

1.30  Crypto 1.6.4

Improvements and New Features

  • Cross compilation improvements and other build system improvements.

    Most notable:

    • 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 $ERL_TOP/INSTALL-CROSS.md file.
    • Support for staged install using DESTDIR. The old broken INSTALL_PREFIX has also been fixed. For more information see the $ERL_TOP/INSTALL.md file.
    • Documentation of the release target of the top Makefile. For more information see the $ERL_TOP/INSTALL.md file.
    • make install now by default creates relative symbolic links instead of absolute ones. For more information see the $ERL_TOP/INSTALL.md file.
    • $ERL_TOP/configure --help=recursive now works and prints help for all applications with configure scripts.
    • Doing make install, or make release directly after make all no longer triggers miscellaneous rebuilds.
    • Existing bootstrap system is now used when doing make install, or make release without a preceding make all.
    • The crypto and ssl applications use the same runtime library path when dynamically linking against libssl.so and libcrypto.so. The runtime library search path has also been extended.
    • The configure scripts of erl_interface and odbc now search for thread libraries and thread library quirks the same way as ERTS do.
    • The configure script of the odbc application now also looks for odbc libraries in lib64 and lib/64 directories when building on a 64-bit system.
    • The config.h.in file in the erl_interface application is now automatically generated in instead of statically updated which reduces the risk of configure tests without any effect.

    (Thanks to Henrik Riomar for suggestions and testing)

    (Thanks to Winston Smith for the AVR32-Linux cross configuration and testing)

    *** POTENTIAL INCOMPATIBILITY ***

    Own Id: OTP-8323

  • 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

1.31  Crypto 1.6.3

Fixed Bugs and Malfunctions

  • Suppressed false valgrind errors caused by libcrypto using uninitialized data as entropy.

    Own Id: OTP-8200

Improvements and New Features

  • 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.

    Own Id: OTP-8281

1.32  Crypto 1.6.2

Fixed Bugs and Malfunctions

    Own Id: OTP-7262

1.38  Crypto 1.5.1.1

Improvements and New Features

  • 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

1.39  Crypto 1.5

Improvements and New Features

    Own Id: OTP-6109

1.40  Crypto 1.4

Improvements and New Features

  • 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 ***

    Own Id: OTP-5631

1.41  Crypto 1.3

Improvements and New Features

  • Added support for RFC 3826 - The Advanced Encryption Standard (AES) Cipher Algorithm in the SNMP User-based Security Model.
    Martin Björklund

1.42  Crypto 1.2.3

Fixed Bugs and Malfunctions

  • 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

1.43  Crypto 1.2.2

Improvements and New Features

  • 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

1.44  Crypto 1.2.1

Fixed Bugs and Malfunctions

  • 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

1.45  Crypto 1.2

Improvements and New Features

  • 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 functions des_ede3_cbc_encrypt/5 and des_ede3_cbc_decrypt/5 have been renamed to des3_cbc_encrypt/5 and des3_cbc_decrypt/5, respectively. The old functions have been retained (they are deprecated and not listed in the crypto(3) manual page).

Reported Fixed Bugs and Malfunctions

  • The start of crypto failed on Windows, due to erroneous addition of a DES3 algorithm.

    Own Id: OTP-4684
    Aux Id: seq7864

1.46  Crypto 1.1.3

Reported Fixed Bugs and Malfunctions

  • 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 crypto_drv.c. This is of importance only for the open source version of Crypto.

1.47  Crypto 1.1.2

Reported Fixed Bugs and Malfunctions

  • 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

1.48  Crypto 1.1.1

Code replacement in runtime is supported. Upgrade can be done from from version 1.1 and downgrade to version 1.1.

Improvements and New Features

  • 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.

1.49  Crypto 1.1

Reported Fixed Bugs and Malfunctions

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

    Own Id: OTP-3240

1.50  Crypto 1.0

New application.
