wolfSSL JNI/JSSE 1.14.0 Now Available
wolfSSL JNI/JSSE 1.14.0 is now available for download! This release contains a number of bug fixes, changes and new features to help better support usage from applications and 3rd party frameworks that consume wolfJSSE internally.
wolfSSL JNI/JSSE allows for easy use of the native wolfSSL SSL/TLS library from Java. The thin JNI wrapper can be used for direct JNI calls into native wolfSSL, or the JSSE provider (wolfJSSE) can be registered as a Java Security provider for seamless integration underneath the Java Security API. wolfSSL JNI/JSSE provides TLS 1.3 support and can also support running on top of wolfCrypt FIPS 140-2 and 140-3 validated modules.
Changes in this release are summarized below, but please see ChangeLog.md for a full list. Watch for individual future blogs on some of these topics as well for a more in depth description.
New JNI and JSSE Functionality:
- Addition of a new WKS KeyStore type to better facilitate FIPS compliance where needed
- Performance and scalability improvement with the use of native poll() set as default over select()
- Support for using RSA-PSS based certificates in TLS connections
- Addition of LDAPS endpoint identification verification to X509ExtendedTrustManager
- Two new JNI wrapped methods for native “wolfSSL_SessionIsSetup()” and “wolfSSL_SESSION_dup()”
JSSE System/Security Property Support:
- wolfjsse.debugFormat=JSON – a new System property to support outputting debug logs in JSON format, which can be more friendly for some log collection mechanisms
- wolfjsse.clientSessionCache.disabled – a new Security property to disable the Java client-side session cache, which will prevent session resumption from occurring
JSSE Changes:
- Native memory leak fixes, related to calls to wolfSSL_get_peer_certificate()
- Optimizations to allow for easier and more efficient garbage collection
- SSLEngine fixes for session storage, unwrap() FINISHED state transitions, HandshakeStatus when receiving TLS 1.3 session tickets after the handshake, correctly closing inbound on ALPN protocol name errors, and closure when fatal alerts are received
- SSLSocket fixes for end of stream handling in InputStream read() calls
- Fixes to throw expected or correct exceptions for several cases
- SSLSession getPeerCertificates() returns correct X509Certificate array
- Fixes around SSLSocket closure in a few different use cases
- Client-side session resumption is now keyed on the cipher suite and protocol in addition to host and port
- Build compatibility has been fixed with the older Android API 24, removing method calls not available in that SDK version
- A potential deadlock on close() between SSLSocket and the associated InputStream read() or OutputStream write() calls has been fixed
Exchange Changes:
- The Host String has been added into the HTTP GET request in the example ClientJSSE when used with the “-g” command line option
- JNI-only threaded client/server example applications have been added which can be helpful for seeing or debugging session resumption at the JNI-only level
- A basic RMI example client and server have been added, which can useful for reference and testing wolfJSSE over RMI
Testing Changes:
- Facebook Infer is now run on all GitHub pull requests using GitHub Actions
- TLS 1.0 and 1.1 JUnit tests are now run even if those protocols are disabled in the system “java.security” file, as long as native wolfSSL support has been compiled in
- Android Gradle builds are now tested on all GitHub pull requests using GitHub Actions

Getting Started with wolfSSL using Visual Studio 2022
It’s never been easier to get started with wolfSSL on Microsoft Windows using Visual Studio 2022!
New VS2022-specific project and solutions files have been created for both the wolfssl/wolfcrypt core library, as well as the test and benchmark examples. These files are available immediately on GitHub and are included in the recent release.
For long term customers and backward-compatibility, we’ve had older versions of Visual Studio that generally would update to whatever latest version might be installed. See our blog post here.
Now with the new VS 2022 files, no more manual adjustments are needed. The project files work immediately out of the box. Just open the project file and click the run button.
Let’s say you’ve just cloned the latest version of wolfSSL from GitHub in your C:\workspace directory:
git clone https://github.com/wolfSSL/wolfssl
The test and benchmark examples also include a vcxproj.user file that aids in pointing the working directory of the project to the root-level wolfSSL to easily find the compiled binary.
To get started with the examples, simply navigate to the wolfCrypt benchmark directory:
C:\workspace\wolfssl\wolfcrypt\benchmark
and open either the benchmark-VS2022.vcxproj project or benchmark-VS2022.sln solution files in Visual Studio 2022.
If you happen to be one of the Windows developers that also uses WSL, you may occasionally see an oddity in Visual Studio’s equivalent of git status as compared to the result from the WSL prompt. The issue is the way Windows might handle file permissions that differ between Windows and Linux when the same file system is shared (e.g. C:\workspace vs /mnt/c/workspace), causing Visual Studio to detect modified files even though there’s no apparent text change. One way to fix this is with this git command:
git config core.fileMode false
Visual Studio may need to be re-launched if it was already already running when the command was entered in a WSL prompt.
When using wolfSSL on Windows, it is a common practice to use a user_settings.h file. There’s an example in the wolfssl/IDE/WIN directory:
https://github.com/wolfSSL/wolfssl/blob/master/IDE/WIN/user_settings.h
The wolfCrypt Benchmark and wolfCrypt Test applications can also be used as reference examples.
Note the beginning of the benchmark.c file. It uses a common pattern of including the wolfssl library:
#ifdef HAVE_CONFIG_H
#include
#endif
#ifndef WOLFSSL_USER_SETTINGS
#include
#endif
#include /* also picks up user_settings.h */
It is important to define the c-compiler preprocessor definition: WOLFSSL_USER_SETTINGS
The #include <wolfssl/wolfcrypt/settings.h> should be listed before any other wolfSSL headers are included. The user_settings.h is included in the settings.h file. The user_settings.h should never be explicitly included in any other source code header.
Beyond the Benchmark and Test Examples
Do you have a project and you’d like to add the wolfssl library? Right-click on the solution file and select “Add – Existing Project…”:
Navigate to the root directory of your wolfSSL source code and add the wolfssl-VS2022.vcxproj file to your solution.
Be sure to also add a reference to each project that will use the wolfssl library. Right click on “references” and add check the “wolfssl” project:
Depending on the directory structure and relative location of the project, the path to the wolfssl source code headers will likely need to be added to the Additional Include Directories. The typical example will be at least for the root directory:
C:/workspace/wolfssl
And oftentimes the user_settings.h as well, shown here in the example IDE/Win directory:
C:/workspace/wolfssl/IDE/Win
The example property page would look like this:
That’s it! Simply build and run the project.
Reorganization Coming Soon
Visual Studio project and solution files will soon be moved to the .\IDE\VS2010.\IDE\VS2022 directories.
The FIPS-related builds currently interspersed in other directories will soon be consolidated and moved to a new .\IDE-FIPS directory. See PR #8126.

curl with FIPS 140-3 wolfSSL
cURL is a popular open-source project that is used to transfer data between client and server with URLs through various protocols. It is widely utilized and often serves as the backbone for data transfer and communication between systems. curl (the command line tool) and libcurl (the library underneath) both provide support for secure communication by leveraging SSL/TLS libraries, the FIPS 140-3 certified wolfSSL library being one of them.
With the wolfCrypt FIPS 140-3 module, wolfSSL provides and makes use of an array of cryptographic algorithms that are rigorously tested and validated under NIST’s CMVP (Cryptographic Module Validation Program). When leveraged with cURL, the result is a FIPS 140-3 compliant build with the full feature set and utility that cURL users have come to expect, in addition to the cryptographic assurance that can help them meet security standards and requirements.
Additionally, there is also the tinycurl library, designed for smaller systems and more embedded use cases. tinycurl has the same capability to utilize FIPS wolfSSL.

Versal Support
Did you know that wolfSSL has been ported to and tested on Xilinx Versal hardware? There is support also in wolfSSL to make use of the Xilinx hardened crypto, enhancing both security and performance. Xilinx hardened crypto has accelerated crypto operations (SHA3-384 / AES-GCM / RSA / ECDSA) available on Ultrascale+ devices and is available for use with the latest and greatest Versal boards. wolfSSL makes these calls using the API from Xilinx’s XilSecure library (https://github.com/Xilinx/embeddedsw/tree/master/lib/sw_services/xilsecure) and with the addition of Versal there was minor changes to the existing calls to make use of the new features available (ECC / RNG / AES-GCM with AAD). When benchmarking we saw well over a Gigabyte per second with AES-GCM operations in our demo and improvements in performance of RSA, ECDSA, and SHA3-384 over software only implementations.
A previous white paper going into the setup and use of wolfSSL on older Ultrascale+ devices with Xilinx hardened crypto can be found here (https://docs.xilinx.com/v/u/en-US/wp512-accel-crypto). The support for Versal along with a README can be found in the wolfSSL bundle located in IDE/XilinxSDK/.

Changes In wolfSSL for ARM Thumb-2 Builds
With wolfSSL release 5.7.4 we added the macro WOLFSSL_ARMASM_THUMB2. This macro can be defined to enable Thumb-2 ARM instruction optimizations and replaces the previous attempted autodetect on the macros __arm__ and __thumb__. Giving users complete control over which ARM assembly optimizations are compiled and used.
When building for Thumb-2 the source files beginning with thumb2-* should additionally be compiled in. If WOLFSSL_ARMASM_THUMB2 is not used then the armv8-32-* files will be used. These files are located in wolfcrypt/src/port/arm/.
The benefit of now having WOLFSSL_ARMASM_THUMB2 is that users can place all files in wolfcrypt/src/port/arm/ to be compiled and use the macro gate for selecting if the Thumb-2 section is optionally compiled or ARM32 implementation is. The armv8-32- code is very similar to the thumb2- code, but Thumb-2 is smaller in size.

wolfSSL Inc. announces Rock-solid curl: long term supported curl releases
Rock-Solid curl: long term supported curl releases
EDMONDS, Wash., Nov. 11, 2024 /PRNewswire-PRWeb/ — wolfSSL INC. (Headquarters: Edmonds, Washington, USA), a vendor specialized in cryptography and network security, announces Rock Solid curl long term supported curl releases. Each release branch will be supported for 5 years. Only security fixes and important stability bug fixes will be merged into the branches, no new features or surprises. Rock-solid curl is available exclusively to all existing support customers released under the same distribution model as normal curl, (or a commercial license). Rock-solid curl is meant to greatly reduce the risk of regressions and yet be a safe and secure solution with full support. For the companies who want this extra level of attention. An even smoother ride. The release schedule for Rock-solid curl release branches are roughly every 18-24 months.
Rock-solid curl 8.9.2 is the first long-term support curl version. As the version number implies, it is based on the curl 8.9.1 release that shipped in July, with two security fixes and a small number of stability patches applied. All current customers under contract will receive the release.
Daniel Stenberg, the original author of curl, has been part of the wolfSSL team since 2019 and will be the primary support for the Rock-solid curl project. Daniel will provide the releases, and most of the patching and the back-porting of what is deemed necessary. Nothing changes with or happens to the original curl project and the regular curl releases because of this, the curl license remains the same. The curl releases and the release cadence remain intact. Support customers help fund the project by allowing us to pay developers.
Downloads and all Rock-solid curl information is hosted on the dedicated rock-solid.curl.dev site, separate from the open source project on curl.se.

Switching to wolfCrypt’s Implementations of Post-Quantum Algorithms
Have you been trying out post-quantum algorithms in wolfSSL’s products? As you probably know, here at wolfSSL we have a step-wise approach to post-quantum algorithm integration:
- Define an API in wolfCrypt.
- Do an integration with an existing reference implementation (ie.: liboqs, PQM4, hash-sigs liblms, xmss-reference).
- Use these APIs in higher level libraries and products (ie.: wolfssl, wolfssh, wolfmqtt, wolfboot) to implement features.
- Invest the time and effort to write and optimize our own production grade implementation of the algorithm.
For LMS, XMSS, ML-KEM and ML-DSA the time has finally come to switch to using wolfSSL’s implementations of these algorithms. It’s very simple to do so. If you are using any of the following configure-time flags simply remove them from your configure command-line:
--with-liblms --with-libxmms --with-liboqs
Then ensure you are enabling the relevant algorithm that you are interested in. Relevant flags are:
--enable-xmss --enable-lms --enable-dilithium --enable-kyber
Once this is done, you will be using our professionally optimized and tested implementations of post-quantum algorithms.
