Affected Users: Anyone using DTLS with wolfSSL versions prior to release 4.5.0. Summary: An issue was discovered in the DTLS handshake implementation in wolfSSL before 4.5.0. Clear DTLS application_data messages in epoch 0 do not produce an out-of-order error. Instead, these messages are returned to the application. Recommendation: Update to wolfSSL version 4.5.0. Research: The […]

The summer release of wolfSSL, v4.5.0, is now available! This release has many new features, optimizations, and bug fixes. Some of the new features we added to the wolfSSL embedded SSL/TLS library include: TLS v1.3 is now enabled by default Building FIPS 140-2 code and test on Solaris Secure renegotiation with DTLS 1.2 Additional OpenSSL […]

wolfBoot is wolfSSL’s universal secure bootloader. It was initially designed to bring secure boot technology to small 32-bit microcontrollers following the guidelines of the IETF SUIT group. But nowadays, it’s used on a large number of heterogeneous devices, from IoT connected systems with limited resources, to faster, more powerful 64-bit embedded Linux systems. Examples of […]

The wolfSSL embedded SSL/TLS library has support for several of the STM32 microcontrollers and for the hardware-based cryptography and random number generator offered by them as well. Our most recent update is that wolfSSL now offers support for STM32Cube Expansion Package enhanced for STM32 toolset, adding on to previous support for the STM32 Standard Peripheral […]

wolfSSL is working hard with our lab to make wolfCrypt be the first cryptography library to have FIPS 140-3 validation. We are very excited about the changes that are a part of FIPS 140-3. We can fit our FIPS validated library into just about any embedded operating environment. wolfSSL currently maintains two FIPS 140-2 certificates […]

FIPS 140-2 requirements for CAVP testing have been deprecated in favor of the cutting edge ACVP test requirements! wolfSSL is currently working on (to our knowledge) the first ever embedded validation that will use the new ACVP test requirements!

Now, with the Azure Sphere OS 20.07 release, Microsoft has licensed and exposed a subset of wolfSSL, the first commercial implementation of TLS 1.3, for use on Azure Sphere devices. This strategic pairing allows software developers to create client TLS connections directly using the Azure Sphere SDK. Software developers no longer need to package their […]

We are exited to announce wolfSSL‘s support for the Renesas RX72N Envision Kit with TSIP v1.09. The RX72N MCU is the flagship model of RX series, using a 32-bit RX72N 240 MHz microcontroller. The board just entered the market this spring and wolfSSL can now support secure connections on it via TLS! If you have […]

wolfSSL is implementing MIKEY-SAKKE! MIKEY-SAKKE is a standard created by the UK government’s National Cyber Security Center (NCSC). MIKEY-SAKKE is a standard designed to enable secure, cross-platform multimedia communications. It is highly scalable, requiring no prior setup between users or distribution of user certificates. It is designed to be centrally-managed, giving a domain manager full […]

Are you a user of Deos? If so, you will be happy to know that wolfSSL supports the Deos Safety Critical RTOS for FAA Certifiable Avionics Applications and has added TLS client/server examples to the wolfSSL embedded SSL/TLS library for Deos! Deos is an embedded RTOS used for safety-critical avionics applications on commercial and military […]
