Every hardware cryptography scheme wolfSSL has ever enabled

At wolfSSL we support hardware cryptography for a wide range of platforms. The benefits of hardware cryptography include reduced code footprint size, improved security, acceleration of cryptographic operations, and utilization of true random number generators. For example, this allows everything from wolfBoot to TLS cipher suites to enjoy acceleration of cryptographic operations.

Furthermore, we have deep partnerships with industry leaders such as Intel, NXP, and Renesas. We support standard Intel instruction extensions such as AES-NI, AVX, and ADX and BMI2, and have recently published a joint whitepaper on using wolfBoot with 11th Gen Intel Core processors. We also support NXP’s Cryptographic Accelerator and Assurance Module (CAAM), and have leveraged this for hardware acceleration on a number of NXP i.MX series processors. Other examples include Espressif and Analog Devices, to name but a few.

If you’re curious for a list of every hardware cryptography scheme and platform we have enabled, then read on:


























Do you have a platform requiring hardware cryptographic support that isn’t on our list, or are you curious about benchmarking?

wolfSSL on the Espressif ESP32-C3 RISC-V

More and more customers are asking about the Espressif ESP32 RISC-V SoC products. The answer is an enthusiastic YES. We support all of the Espressif ESP-32 chipsets, including the ESP32-C6 and the ESP32-C3 RISC-V devices.

Check out our recent video: Getting Started with wolfSSL on the ESP32. Our Espressif examples make it easier than ever to take wolfSSL for a test drive. See also the recent blog on the ESP Component Registry and other blogs on the ESP32 topic.

Shown below is an out-of-the-box, default-settings version of wolfSSL running the Benchmark app on the ESP32-C3 in a typical ESP-IDF v5.1 environment. Keep in mind there are numerous wolfSSL settings to fine-tune our libraries to your product.

We currently have RISC-V hardware acceleration in development. This means that some of the performance metrics should improve by upwards of 10x faster.

Announcing wolfSSL sniffer support for key log files (SSLKEYLOGFILE)

We are excited to announce that the wolfSSL sniffer now supports TLS session decryption for recorded TLS traffic using a SSLKEYLOGFILE!

If you didn’t already know about our sniffer tool, it is a utility library built into wolfSSL that can be used to capture and decrypt live traffic or recorded PCAP traces. Previously, the sniffer could only decrypt traffic from sessions where either the static private key (RSA, ECC) or the ephemeral key (DHE, ECDHE) was known and able to be provided to the sniffer at runtime. This required keeping track of the private or ephemeral key files for every session you wanted to sniff, which was cumbersome for packet captures containing a large number of sessions, especially for TLS v1.3 where each session would require a new ephemeral key to decrypt.

If your server or client is able to generate a key log file (which wolfSSL can do with the `–enable-keylog-export` option), you can now simply register this file with the sniffer and the sniffer will be able to decrypt all applicable traffic in your packet capture, regardless of the cipher suite used!

To build wolfSSL with the sniffer enabled use the `–enable-sniffer` configure option. To enable key log file support in the sniffer, simply define `WOLFSSL_SNIFFER_KEYLOGFILE`:

./configure --enable-sniffer CFLAGS=“-DWOLFSSL_SNIFFER_KEYLOGFILE”

WolfSSL provides the snifftest demo application that demonstrates how to use the sniffer library to sniff traffic from both live and recorded packet captures. Using the snifftest app to sniff traffic from a packet capture with an associated key log file is as simple as running:

# Sniffs traffic from a server at on port 11111
./snifftest -pcap /path/to/your.pcap \
            -keylogfile /path/to/your/keylogfile.log \
            -server \
            -port 11111 

For more information and examples showing how to get started with the sniffer, please refer to the snifftest demo application and README.

Added Support for DTLS 1.3 Authentication and Integrity-Only Cipher Suites

As you may already know, DTLS is a protocol designed to secure communication over UDP, particularly suited for constrained IoT devices and use cases where low latency is crucial. wolfSSL stands out as the first provider of a production-ready implementation of the DTLS v1.3 protocol, which is based on TLS v1.3. One of the key advantages of wolfSSL’s DTLS v1.3 implementation is its ability to reuse most parts of the mature wolfSSL TLS 1.3 stack. This not only enables broad hardware support but also ensures that all wolfSSL features, such as post-quantum, HSMs, etc. are supported out of the box.

Indeed only some minor tweaks were needed to add Authentication and Integrity-Only cipher suites support for DTLS v1.3 in wolfSSL version 5.6.2! These cipher suites (TLS_SHA256_SHA256 and TLS_SHA384_SHA384) ensure authentication and integrity but do not provide confidentiality, as messages are sent in clear form. This means that you can be assured of the identity of the communicating entities and promptly detect any unauthorized modifications of the messages, even if they can be read by anyone that can intercept the communication.

There are numerous use cases where authenticity and integrity are of utmost importance, even if confidentiality is not a requirement. This can be especially advantageous for memory and performance-constrained devices, where no confidentiality can lower the number of required cryptographic algorithms, leading to efficient utilization of scarce resources. Industrial automation, industrial control, railways, and civil avionics are a few examples of industries where these cipher suites find practical applications. In other scenarios, third-party inspection of the communication is needed while preserving authenticity and integrity properties; this is also supported thanks to the lack of confidentiality of these cipher suites.

For example RFC 9372 (L-Band Digital Aeronautical Communications System – LDACS), explain how ICAO doc 9896 foresee layer security for all aeronautical data and that DTLS v1.3 provides the security requirement reported from ARINC 858P1. To further insights into how Authentication and Integrity-Only Cipher Suites can be used, refer to RFC 9150, which outlines typical use case scenarios.

In summary wolfSSL’s DTLS v1.3 implementation offers yet another feature: the ability to run on highly constrained memory and performance devices with Authentication and Integrity-Only Cipher Suites. This paves the way for providing authentication and integrity protection while allowing third-party inspection of the communication. To start exploring these capabilities, you can download the source code from our repository on GitHub at

Live Webinar: SM Ciphers are now implemented in wolfSSL; how to access them, use them, and what sets them apart

We are excited to announce that the SM cipher webinar will once again be available for those residing in the European time zone! We invite you to join us for an enlightening webinar discussing the launch of wolfSSL’s SM cipher implementations.

Save the date: 8/24/2023 at 10 am CET

As many people know, Chinese government regulators are now mandating use of SM2, SM3 and SM4 in critical systems, including automobiles, avionics, power systems, and communication systems. Since many of our customers are multi-nationals that do business in China, they have been requesting the addition of these algorithms in wolfSSL products.

We recently released our supported versions of SM2, SM3, and SM4, with the intention to release the ZUC stream cipher at some point this year to completely satisfy SM9. We are also in contact with labs regarding support of OSCCA certification at some point in the future. This is really great news for our customers in Chinese markets!

For those readers considering using wolfSSL products, here’s some additional notes:

  1. The SM Ciphers are fully supported in wolfSSL’s TLS 1.3 and DTLS 1.3 implementations.
  2. wolfSSH, wolfBoot and our other products will support ShangMi ciphers.
  3. ARM, Intel, and RiscV assembly is in the works for our SM implementations for maximum performance
  4. We support bare metal for SM2, SM3, and SM4.
  5. We have maximized performance and minimized size, so the ShangMi algorithms will work well for embedded systems use cases on a wide variety of microcontrollers (MCU’s). They will be available for all of the MCU silicon that we currently support, including STM32, NXP i.MX, RISC-V, Renesas RA, RX, and Synergy, Nordic NRF32, Microchip PIC32, Infineon Aurix, TI MSP, and many others.
  6. Our GPLv2 versions of the SM ciphers are available for download on GitHub

Commercially licensed versions are available.

Static library framework for Apple devices

We’ve got an exciting new update for our Apple ecosystem support! wolfSSL now contains a script that automates building and packaging wolfSSL static libraries as an XCFramework that can run on all Apple platforms and targets, further simplifying integration into your Xcode projects.

Instead of manually adding all wolfSSL source files to your Xcode project and having to use a user_settings.h file, you can now simply run the script with your desired configure options to build and package wolfSSL, and then drag-and-drop the imported framework bundle into XCode. The framework bundle contains wolfSSL static libraries targeting all modern Apple platforms and simulators. This includes MacOS (arm64, x86_64), iPhone (arm64), iPhoneSimulator (arm64, x86_64), appleTV (arm64), appleTVSimulator (arm64, x86_64), appleWatch (arm64), and appleWatchSimulator (arm64, x86_64). We also include a new “wolfssl-multiplatform” demo application in Xcode demonstrating how a swift application can use a “bridging header” to call into C code and use wolfSSL.

You can find the new build utilities and the “wolfssl-multiplatform” example app in the wolfSSL source tree at IDE/apple-universal. Check out the README to get started. Integrating wolfSSL to your Xcode project has never been easier!

As always, if you have questions on any of the above, please contact us at, or call us at +1 425 245 8247.
