TLDR: wolfSSL can run over CAN Bus. This means wolfSSL can secure CAN Bus, which is typically insecure. As such, you can now authenticate over CAN Bus and encrypt over CAN Bus. The CAN (Controller Area Network) bus is a common data bus used in vehicles for onboard microcontrollers to communicate to each other. Modern […]

Support for Renesas TSIP v1.13 on RX72N
We’re happy to announce that we’ve added support for Renesas TSIP v1.13 on RX72N in wolfSSL v5.0.0! The RX72N MCU is the flagship model of RX series, using a 32-bit RX72N 240 MHz microcontroller.Using the TSIP driver, wolfSSL can offload supported cryptographic and TLS operations to the underlying Renesas hardware for increased performance. If you have […]
Read MoreMore TagwolfSSL Added Support for pyOpenSSL
One of the highlights of our wolfSSL library is its exceptional portability, which allows wolfSSL’s team of engineers to frequently add new ports! We’re happy to announce that we’ve added support for pyOpenSSL in wolfSSL v5.0.0! We have integrated wolfSSL with the pyOpenSSL project, which allows for the use of pyOpenSSL with our SSL/TLS library, wolfSSL. pyOpenSSL is […]
Read MoreMore TagOpen Quantum Safe and wolfSSL Joint Wireshark Integration
In a recent blog post we showed the details of a quantum-safe connection using wireshark. This post is to announce that now you can also do the exact same thing by following instructions provided by our friends at the Open Quantum Safe group. They have generously hosted a wireshark integration via docker that will display […]
Read MoreMore TagOpenSSL 3.0 Provider Solution with FIPS
As you may know, wolfSSL has integrated our FIPS-certified crypto module, wolfCrypt, with OpenSSL as an OpenSSL engine, in a product we call wolfEngine. OpenSSL 3.0 has done away with the engines paradigm in favor of a new concept, called providers. wolfSSL now has a FIPS 140-2 solution for an OpenSSL 3.0 provider, allowing you […]
Read MoreMore TagwolfBoot UEFI Support
We’re happy to announce that we’ve added experimental support to run wolfBoot as an EFI application! The Unified Extensible Firmware Interface (UEFI) is a specification that describes an interface between the operating system (OS) and the platform firmware and it replaces the old BIOS-like firmware. Now wolfBoot can run inside the UEFI environment on Intel […]
Read MoreMore TagPower Usage Benchmark with EEMBC
The latest benchmarks of wolfSSL power consumption on an STM32L476G device are up (https://www.eembc.org/viewer/?benchmark_seq=13436). What we found is that using wolfSSL’s SP math (with assembly speed ups) is superior on the device. It has a positive impact on both the speed and power consumption. With the measurements used with EEMBC (https://www.eembc.org/) higher final scores are […]
Read MoreMore TagwolfSSL NXP SE050 Support
We are excited to announce wolfSSL’s support for the NXP SE050. The wolfSSL SE050 port supports a variety of algorithms including: SHA, SHA2-224, SHA2-256, SHA2-384, SHA2-512, AES-CBC, AES-ECB, ECDSA, ECDHE and most notably ED25519 / CURVE25519. In the tested configuration a Raspberry Pi 2b was connected to the SE050 dev kit through a header board. […]
Read MoreMore TagMQTT Secure Firmware Update Example
Our wolfMQTT project includes an example for secure firmware update or Over the Air (OTA) update. This example uses the wolfSSL embedded SSL/TLS library to hash/sign the binary image and send it over MQTT. The example has two applications. One is called fwpush, which hashes, signs and publishes the firmware image over TLS to an MQTT broker. The second is […]
Read MoreMore TagwolfSSL Support Added for Python
We’re happy to announce that we’ve added wolfSSL support to Python version 3.8.5 using our OpenSSL compatibility layer! The wolfSSL port allows you to use Python with our FIPS 140-2/3 certified wolfCrypt library. To build Python with wolfSSL, follow the instructions in our open source projects repository here. To view wolfSSL’s collection of open source […]
