wolfSSL Release 4.0.0 (03/20/2019)

Release 4.0.0 of wolfSSL embedded TLS has bug fixes and new features including:

This release of wolfSSL includes a fix for 1 security vulnerability.

wolfSSL Release 3.15.7 (12/26/2018)

Release 3.15.7 of wolfSSL embedded TLS has bug fixes and new features including:

This release of wolfSSL includes a fix for 1 security vulnerability.

Medium level fix for potential cache attack with a variant of Bleichenbacher’s attack. Earlier versions of wolfSSL leaked PKCS #1 v1.5 padding information during private key decryption that could lead to a potential padding oracle attack. It is recommended that users update to the latest version of wolfSSL if they have RSA cipher suites enabled and have the potential for malicious software to be ran on the same system that is performing RSA operations. Users that have only ECC cipher suites enabled and are not performing RSA PKCS #1 v1.5 Decryption operations are not vulnerable. Also users with TLS 1.3 only connections are not vulnerable to this attack. Thanks to Eyal Ronen (Weizmann Institute), Robert Gillham (University of Adelaide), Daniel Genkin (University of Michigan), Adi Shamir (Weizmann Institute), David Wong (NCC Group), and Yuval Yarom (University of Adelaide and Data61) for the report.

The paper for further reading on the attack details can be found at http://cat.eyalro.net/cat.pdf.

wolfSSL Release 3.15.3 (6/20/2018)

Release 3.15.3 of wolfSSL embedded TLS has bug fixes and new features including:

This release of wolfSSL fixes 2 security vulnerability fixes.

Medium level fix for PRIME + PROBE attack combined with a variant of Lucky 13. Constant time hardening was done to avoid potential cache-based side channel attacks when verifying the MAC on a TLS packet. CBC cipher suites are susceptible on systems where an attacker could gain access and run a parallel program for inspecting caching. Only wolfSSL users that are using TLS/DTLS CBC cipher suites need to update. Users that have only AEAD and stream cipher suites set, or have built with WOLFSSL_MAX_STRENGTH (–enable-maxstrength), are not vulnerable. Thanks to Eyal Ronen, Kenny Paterson, and Adi Shamir for the report.

Medium level fix for a ECDSA side channel attack. wolfSSL is one of over a dozen vendors mentioned in the recent Technical Advisory “ROHNP” by author Ryan Keegan. Only wolfSSL users with long term ECDSA private keys using our fastmath or normal math libraries on systems where attackers can get access to the machine using the ECDSA key need to update. An attacker gaining access to the system could mount a memory cache side channel attack that could recover the key within a few thousand signatures. wolfSSL users that are not using ECDSA private keys, that are using the single precision math library, or that are using ECDSA offloading do not need to update.

This release of wolfSSL fixes 1 security vulnerability.

wolfSSL is cited in the recent ROBOT Attack by Böck, Somorovsky, and Young. The paper notes that wolfSSL only gives a weak oracle without a practical attack but this is still a flaw. This release contains a fix for this report. Please note that wolfSSL has static RSA cipher suites disabled by default as of version 3.6.6 because of the lack of perfect forward secrecy. Only users who have explicitly enabled static RSA cipher suites with WOLFSSL_STATIC_RSA and use those suites on a host are affected. More information will be available on our website at:

Release 3.12.0 of wolfSSL has bug fixes and new features including:

Note: There is a known issue with using ChaCha20 AVX assembly on versions of GCC earlier than 5.2. This is encountered with using the wolfSSL enable options –enable-intelasm and –enable-chacha. To avoid this issue ChaCha20 can be enabled with –enable-chacha=noasm. If using –enable-intelasm and also using –enable-sha224 or –enable-sha256 there is a known issue with trying to use -fsanitize=address.

This release of wolfSSL fixes 1 low level security vulnerability.

Low level fix for a potential DoS attack on a wolfSSL client. Previously a client would accept many warning alert messages without a limit. This fix puts a limit to the number of warning alert messages received and if this limit is reached a fatal error ALERT_COUNT_E is returned. The max number of warning alerts by default is set to 5 and can be adjusted with the macro WOLFSSL_ALERT_COUNT_MAX. Thanks for the report from Tarun Yadav and Koustav Sadhukhan from Defence Research and Development Organization, INDIA.

CTaoCrypt now has support for the Microchip PIC32 and has been tested with the Microchip PIC32 Ethernet Starter Kit, the XC32 compiler and MPLAB X IDE in both MIPS16 and MIPS32 instruction set modes. See the README located under the <cyassl_root>/mplabx directory for more details.

To add Cavium NITROX support do:

./configure –with-cavium=/home/user/cavium/software

pointing to your licensed cavium/software directory. Since Cavium doesn't build a library we pull in the cavium_common.o file which gives a libtool warning about the portability of this. Also, if you're using the github source tree you'll need to remove the -Wredundant-decls warning from the generated Makefile because the cavium headers don't conform to this warning. Currently CyaSSL supports Cavium RNG, AES, 3DES, RC4, HMAC, and RSA directly at the crypto layer. Support at the SSL level is partial and currently just does AES, 3DES, and RC4. RSA and HMAC are slower until the Cavium calls can be utilized in non blocking mode. The example client turns on cavium support as does the crypto test and benchmark. Please see the HAVE_CAVIUM define.

CyaSSL is able to use the STM32F2 hardware-based cryptography and random number generator through the STM32F2 Standard Peripheral Library. For necessary defines, see the CYASSL_STM32F2 define in settings.h. Documentation for the STM32F2 Standard Peripheral Library can be found in the following document: http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/USER_MANUAL/DM00023896.pdf

To enable certificate generation support add this option to ./configure ./configure –enable-certgen

An example is included in ctaocrypt/test/test.c and documentation is provided in doc/CyaSSL_Extensions_Reference.pdf item 11.

CyaSSL Release 1.6.0 (8/27/2010)

Release 1.6.0 for CyaSSL adds bug fixes, RIPEMD-160, SHA-512, and RSA key generation.

For general build instructions see doc/Building_CyaSSL.pdf.

To add RIPEMD-160 support add this option to ./configure ./configure –enable-ripemd

To add SHA-512 support add this option to ./configure ./configure –enable-sha512

To add RSA key generation support add this option to ./configure ./configure –enable-keygen

Please see ctaocrypt/test/test.c for examples and usage.

For Windows, RIPEMD-160 and SHA-512 are enabled by default but key generation is off by default. To turn key generation on add the define CYASSL_KEY_GEN to CyaSSL.

CyaSSL Release 1.5.6 (7/28/2010)

Release 1.5.6 for CyaSSL adds bug fixes, compatibility for our JSSE provider, and a fix for GCC builds on some systems.

For general build instructions see doc/Building_CyaSSL.pdf.

To add AES-NI support add this option to ./configure ./configure –enable-aesni

You'll need GCC 4.4.3 or later to make use of the assembly.

CyaSSL Release 1.5.4 (7/7/2010)

Release 1.5.4 for CyaSSL adds bug fixes, support for AES-NI, SHA1 speed improvements from loop unrolling, and support for the Mongoose Web Server.

For general build instructions see doc/Building_CyaSSL.pdf.

To add AES-NI support add this option to ./configure ./configure –enable-aesni

You'll need GCC 4.4.3 or later to make use of the assembly.

CyaSSL Release 1.5.0 (5/11/2010)

Release 1.5.0 for CyaSSL adds bug fixes, GoAhead WebServer support, sniffer support, and initial swig interface support.

For general build instructions see doc/Building_CyaSSL.pdf.

To add support for GoAhead WebServer either –enable-opensslExtra or if you don't want all the features of opensslExtra you can just define GOAHEAD_WS instead. GOAHEAD_WS can be added to ./configure with CFLAGS=-DGOAHEAD_WS or you can define it yourself.

To look at the sniffer support please see the sniffertest app in sslSniffer/sslSnifferTest. Build with –enable-sniffer on *nix or use the vcproj files on windows. You'll need to have pcap installed on *nix and WinPcap on windows.

A swig interface file is now located in the swig directory for using Python, Java, Perl, and others with CyaSSL. This is initial support and experimental, please send questions or comments to suppo.nosp@m.rt@y.nosp@m.assl..nosp@m.com.

When doing load testing with CyaSSL, on the echoserver example say, the client machine may run out of tcp ephemeral ports, they will end up in the TIME_WAIT queue, and can't be reused by default. There are generally two ways to fix this.

  1. Reduce the length sockets remain on the TIME_WAIT queue OR
  2. Allow items on the TIME_WAIT queue to be reused.

To reduce the TIME_WAIT length in OS X to 3 seconds (3000 milliseconds)

sudo sysctl -w net.inet.tcp.msl=3000

In Linux

sudo sysctl -w net.ipv4.tcp_tw_reuse=1

allows reuse of sockets in TIME_WAIT

sudo sysctl -w net.ipv4.tcp_tw_recycle=1

works but seems to remove sockets from TIME_WAIT entirely?

sudo sysctl -w net.ipv4.tcp_fin_timeout=1

doen't control TIME_WAIT, it controls FIN_WAIT(2) contrary to some posts

CyaSSL Release 1.4.0 (2/18/2010)

For general build instructions see rc1 below.

CyaSSL Release 1.2.0 (11/2/2009)

Release 1.2.0 for CyaSSL adds bug fixes and session negotiation if first use is read or write.

For general build instructions see rc1 below.

CyaSSL Release 1.1.0 (9/2/2009)

Release 1.1.0 for CyaSSL adds bug fixes, a check against malicious session cache use, support for lighttpd, and TLS 1.2.

To get TLS 1.2 support please use the client and server functions:

SSL_METHOD *TLSv1_2_server_method(void);
SSL_METHOD *TLSv1_2_client_method(void);

CyaSSL was tested against lighttpd 1.4.23. To build CyaSSL for use with lighttpd use the following commands from the CyaSSL install dir <CyaSSLDir>:

./configure --disable-shared --enable-opensslExtra --enable-fastmath --without-zlib
make
make openssl-links

Then to build lighttpd with CyaSSL use the following commands from the lighttpd install dir:

./configure --with-openssl --with-openssl-includes=<CyaSSLDir>/include --with-openssl-libs=<CyaSSLDir>/lib LDFLAGS=-lm
make

On some systems you may get a linker error about a duplicate symbol for MD5_Init or other MD5 calls. This seems to be caused by the lighttpd src file md5.c, which defines MD5_Init(), and is included in liblightcomp_la-md5.o. When liblightcomp is linked with the SSL_LIBs the linker may complain about the duplicate symbol. This can be fixed by editing the lighttpd src file md5.c and adding this line to the beginning of the file:

#if 0

and this line to the end of the file

#endif

Then from the lighttpd src dir do a:

make clean
make

If you get link errors about undefined symbols more than likely the actual OpenSSL libraries are found by the linker before the CyaSSL openssl-links that point to the CyaSSL library, causing the linker confusion. This can be fixed by editing the Makefile in the lighttpd src directory and changing the line:

SSL_LIB = -lssl -lcrypto

to

SSL_LIB = -lcyassl

Then from the lighttpd src dir do a:

make clean
make

This should remove any confusion the linker may be having with missing symbols.

For any questions or concerns please contact suppo.nosp@m.rt@y.nosp@m.assl..nosp@m.com .

CyaSSL Release 1.0.6 (8/03/2009)

Release 1.0.6 for CyaSSL adds bug fixes, an improved session cache, and faster math with a huge code option.

The session cache now defaults to a client mode, also good for embedded servers. For servers not under heavy load (less than 200 new sessions per minute), define BIG_SESSION_CACHE. If the server will be under heavy load, define HUGE_SESSION_CACHE.

There is now a fasthugemath option for configure. This enables fastmath plus even faster math by greatly increasing the code size of the math library. Use the benchmark utility to compare public key operations.

For general build instructions see rc1 below.

CyaSSL Release 1.0.3 (5/10/2009)

Release 1.0.3 for CyaSSL adds bug fixes and add increased support for OpenSSL compatibility when building other applications.

Release 1.0.3 includes an alpha release of DTLS for both client and servers. This is only for testing purposes at this time. Rebroadcast and reordering aren't fully implemented at this time but will be for the next release.

For general build instructions see rc1 below.

CyaSSL Release 1.0.2 (4/3/2009)

Release 1.0.2 for CyaSSL adds bug fixes for a couple I/O issues. Some systems will send a SIGPIPE on socket recv() at any time and this should be handled by the application by turning off SIGPIPE through setsockopt() or returning from the handler.

Release 1.0.2 includes an alpha release of DTLS for both client and servers. This is only for testing purposes at this time. Rebroadcast and reordering aren't fully implemented at this time but will be for the next release.

For general build instructions see rc1 below.

CyaSSL Release Candidate 3 rc3-1.0.0 (2/25/2009)

Release Candidate 3 for CyaSSL 1.0.0 adds bug fixes and adds a project file for iPhone development with Xcode. cyassl-iphone.xcodeproj is located in the root directory. This release also includes a fix for supporting other implementations that bundle multiple messages at the record layer, this was lost when cyassl i/o was re-implemented but is now fixed.

For general build instructions see rc1 below.

CyaSSL Release Candidate 2 rc2-1.0.0 (1/21/2009)

Release Candidate 2 for CyaSSL 1.0.0 adds bug fixes and adds two new stream ciphers along with their respective cipher suites. CyaSSL adds support for HC-128 and RABBIT stream ciphers. The new suites are:

TLS_RSA_WITH_HC_128_SHA
TLS_RSA_WITH_RABBIT_SHA

And the corresponding cipher names are

HC128-SHA
RABBIT-SHA

CyaSSL also adds support for building with devkitPro for PPC by changing the library proper to use libogc. The examples haven't been changed yet but if there's interest they can be. Here's an example ./configure to build CyaSSL for devkitPro:

./configure --disable-shared CC=/pathTo/devkitpro/devkitPPC/bin/powerpc-gekko-gcc --host=ppc --without-zlib --enable-singleThreaded RANLIB=/pathTo/devkitpro/devkitPPC/bin/powerpc-gekko-ranlib CFLAGS="-DDEVKITPRO -DGEKKO"

For linking purposes you'll need

LDFLAGS="-g -mrvl -mcpu=750 -meabi -mhard-float -Wl,-Map,$(notdir $@).map"

For general build instructions see rc1 below.

CyaSSL Release Candidate 1 rc1-1.0.0 (12/17/2008)

Release Candidate 1 for CyaSSL 1.0.0 contains major internal changes. Several areas have optimization improvements, less dynamic memory use, and the I/O strategy has been refactored to allow alternate I/O handling or Library use. Many thanks to Thierry Fournier for providing these ideas and most of the work.

Because of these changes, this release is only a candidate since some problems are probably inevitable on some platform with some I/O use. Please report any problems and we'll try to resolve them as soon as possible. You can contact us at suppo.nosp@m.rt@y.nosp@m.assl..nosp@m.com or todd@.nosp@m.yass.nosp@m.l.com.

Using TomsFastMath by passing –enable-fastmath to ./configure now uses assembly on some platforms. This is new so please report any problems as every compiler, mode, OS combination hasn't been tested. On ia32 all of the registers need to be available so be sure to pass these options to CFLAGS:

CFLAGS="-O3 -fomit-frame-pointer"

OS X will also need -mdynamic-no-pic added to CFLAGS

Also if you're building in shared mode for ia32 you'll need to pass options to LDFLAGS as well on OS X:

LDFLAGS=-Wl,-read_only_relocs,warning

This gives warnings for some symbols but seems to work.

To build on Linux, Solaris, *BSD, Mac OS X, or Cygwin:

./configure
make

from the ./testsuite/ directory run ./testsuite 

To make a debug build:

./configure --enable-debug --disable-shared
make

To build on Win32

Choose (Re)Build All from the project workspace

Run the testsuite program

CyaSSL version 0.9.9 (7/25/2008)

This release of CyaSSL adds bug fixes, Pre-Shared Keys, over-rideable memory handling, and optionally TomsFastMath. Thanks to Moisés Guimarães for the work on TomsFastMath.

To optionally use TomsFastMath pass –enable-fastmath to ./configure Or define USE_FAST_MATH in each project from CyaSSL for MSVC.

Please use the benchmark routine before and after to see the performance difference, on some platforms the gains will be little but RSA encryption always seems to be faster. On x86-64 machines with GCC the normal math library may outperform the fast one when using CFLAGS=-m64 because TomsFastMath can't yet use -m64 because of GCCs inability to do 128bit division.

 *** UPDATE GCC 4.2.1 can now do 128bit division ***

See notes below (0.2.0) for complete build instructions.

CyaSSL version 0.9.8 (5/7/2008)

This release of CyaSSL adds bug fixes, client side Diffie-Hellman, and better socket handling.

See notes below (0.2.0) for complete build instructions.

CyaSSL version 0.9.6 (1/31/2008)

This release of CyaSSL adds bug fixes, increased session management, and a fix for gnutls.

See notes below (0.2.0) for complete build instructions.

CyaSSL version 0.9.0 (10/15/2007)

This release of CyaSSL adds bug fixes, MSVC 2005 support, GCC 4.2 support, IPV6 support and test, and new test certificates.

See notes below (0.2.0) for complete build instructions.

CyaSSL version 0.8.0 (1/10/2007)

This release of CyaSSL adds increased socket support, for non-blocking writes, connects, and interrupted system calls.

See notes below (0.2.0) for complete build instructions.

CyaSSL version 0.6.3 (10/30/2006)

This release of CyaSSL adds debug logging to stderr to aid in the debugging of CyaSSL on systems that may not provide the best support.

If CyaSSL is built with debugging support then you need to call CyaSSL_Debugging_ON() to turn logging on.

On Unix use ./configure –enable-debug

On Windows define DEBUG_CYASSL when building CyaSSL

To turn logging back off call CyaSSL_Debugging_OFF()

See notes below (0.2.0) for complete build instructions.

CyaSSL version 0.6.2 (10/29/2006)

This release of CyaSSL adds TLS 1.1.

Note that CyaSSL has certificate verification on by default, unlike OpenSSL. To emulate OpenSSL behavior, you must call SSL_CTX_set_verify() with SSL_VERIFY_NONE. In order to have full security you should never do this, provide CyaSSL with the proper certificates to eliminate impostors and call CyaSSL_check_domain_name() to prevent man in the middle attacks.

See notes below (0.2.0) for build instructions.

CyaSSL version 0.6.0 (10/25/2006)

This release of CyaSSL adds more SSL functions, better autoconf, nonblocking I/O for accept, connect, and read. There is now an –enable-small configure option that turns off TLS, AES, DES3, HMAC, and ERROR_STRINGS, see configure.in for the defines. Note that TLS requires HMAC and AES requires TLS.

See notes below (0.2.0) for build instructions.

CyaSSL version 0.5.5 (09/27/2006)

This mini release of CyaSSL adds better input processing through buffered input and big message support. Added SSL_pending() and some sanity checks on user settings.

See notes below (0.2.0) for build instructions.

CyaSSL version 0.5.0 (03/27/2006)

This release of CyaSSL adds AES support and minor bug fixes.

See notes below (0.2.0) for build instructions.

See notes below for build instructions.

CyaSSL version 0.3.0 (02/26/2006)

This release of CyaSSL adds SSLv3 server support and session resumption.

See notes below for build instructions.

CyaSSL version 0.2.0 (02/19/2006)

This is the first release of CyaSSL and its crypt brother, CTaoCrypt. CyaSSL is written in ANSI C with the idea of a small code size, footprint, and memory usage in mind. CTaoCrypt can be as small as 32K, and the current client version of CyaSSL can be as small as 12K.

The first release of CTaoCrypt supports MD5, SHA-1, 3DES, ARC4, Big Integer Support, RSA, ASN parsing, and basic x509 (en/de)coding.

The first release of CyaSSL supports normal client RSA mode SSLv3 connections with support for SHA-1 and MD5 digests. Ciphers include 3DES and RC4.
