We have extended wolfSSL’s Renesas Secure Crypto Engine (SCE) support to include a crypt-only build for the Renesas RA6M4. wolfSSL already supports Renesas SCE for TLS communication. In addition to our existing TLS support, the SCE driver can be used for standalone cryptographic operations. Using this mode, users are able to gain not only the […]

There is a common theme in all wolfSSL products which is that they basically involve two parties. For wolfSSL, wolfSSH, wolfMQTT and cURL libraries there is a server and a client. For wolfBoot, you have the boot loader and firmware provider. For wolfTPM you have the user and the TPM. For wolfSentry you have the […]

We’re happy to announce that we have added wolfBoot support for the Renesas RA6M4! The Renesas RA6M4 group uses a high-performance Arm Cortex-M33 core with TrustZone. The RA6M4 is supported by an open and flexible ecosystem concept – the Flexible Software Package (FSP), built on FreeRTOS – and is expandable to use other RTOS and […]

Today we are happy to announce the availability of an Ada/SPARK binding that enables Ada applications to use post-quantum TLS 1.3 encryption through the wolfSSL embedded SSL/TLS library. It opens the door to obtaining FIPS 140-3 and DO-178C certifications for Ada and Spark applications that use TLS for their encrypted communications and also makes them […]

wolfBoot v1.16 has been released. This version introduces a key component to facilitate staging on microprocessor-based embedded systems: an optional safe ELF format parser. The support for PowerPC architecture has been improved, now allowing the complete staging from RAM. The support for NXP P1021 has been extended, as well as for Renesas RA6M4 and RX72N. […]

The latest wolfSentry release, version 1.4, adds advanced traffic attribute filters and controls, allowing field-configurable stateful routes for DNS and other connectionless protocols, and transparent port scanner detection and defenses. Event handlers can be configured to restrict matches to traffic with specified attributes, such as inbound or outbound connection initiation or closure, binding of a […]

We needed a way to reproduce GitHub Actions’ ability to only rerun those tests that failed in Jenkins. This is to speed up the re-testing in addition to reducing costs. Looking around no one really had a solution for this. So we wrote our own. This is the declarative pipeline that calls multiple jobs on […]

wolfSSL has added support for handling “Raw Public Keys (RPK)”. This blog post provides an overview of the RPK and explains how to use it with wolfSSL. Who Needs Raw Public Keys Embedded devices that implement TLS are increasing, but certificate chain verification is a heavy load for devices with severe resource (MCU power and […]

We are excited to announce that wolfSSL has added support for the hitch project! Hitch is a scalable TLS/SSL proxy developed by Varnish software. It’s designed to handle tens of thousands of connections efficiently on multicore machines. wolfSSL has recently added support for hitch as part of our open source support efforts. This means you […]

Please join us for an informative webinar about the release of wolfSSL’s SM cipher implementations. 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 […]
