Support for STM32_PKA Accelerator

wolfSSL is a proud partner of STMicroelectronics, and we support a great many of their products. Now we have added support for the STM32_PKA accelerator found in the STM32WB55 module.

The STM32WB55 module is is a heterogeneous dual-core MCU with a Cortex-M4 for the end-user application and a Cortex-M0 for the BLE stack. This PKA module accelerates ECC sign and verification. The measured performance is 160ms per ECC SECP256R1 verification. This option is enabled with the WOLFSSL_STM32_PKA build option and is demonstrated with our wolfBoot library.

Support added in PR 2498:
https://github.com/wolfSSL/wolfssl/pull/2498

wolfBoot implementation details can be found here.

wolfSSL FIPS Ready and curl (#wolfSSL #wolfCrypt #curl)

wolfSSL FIPS Ready

Along with the recent release of wolfSSL v4.1.0, wolfSSL has updated its support for the wolfCrypt FIPS Ready version of the wolfSSL library. wolfCrypt FIPS Ready is our FIPS enabled cryptography layer included in the wolfSSL source tree that can be enabled and built. To elaborate on what FIPS Ready really means: you do not get a FIPS certificate and you are not FIPS approved. FIPS Ready means that you have included the FIPS code into your build and that you are operating according to the FIPS enforced best practices of default entry point, and Power On Self Test (POST).

FIPS Ready with curl

(modified from Daniel Stenberg

The integration of wolfSSL and curl means that the curl library can also be built using the wolfCrypt FIPS ready library. The following outlines the steps for building curl with FIPS Ready:

1. Download wolfSSL fips ready

2. Unzip the source code somewhere suitable:

$ cd $HOME/src
$ unzip wolfssl-4.1.0-gplv3-fips-ready.zip
$ cd wolfssl-4.1.0-gplv3-fips-ready

3. Build the fips-ready wolfSSL and install it somewhere suitable:

$ ./configure --prefix=$HOME/wolfssl-fips --enable-harden --enable-all
$ make -sj
$ make install

4. Download curl, the normal curl package.

5. Unzip the source code somewhere suitable:

$ cd $HOME/src
$ unzip curl-7.66.0.zip
$ cd curl-7.66.0

6. Build curl with the just recently built and installed FIPS ready wolfSSL version:

$ LD_LIBRARY_PATH=$HOME/wolfssl-fips/lib ./configure --with-wolfssl=$HOME/wolfssl-fips --without-ssl
$ make -sj

7. Now, verify that your new build matches your expectations by:

$ ./src/curl -V

It should show that it uses wolfSSL and that all the protocols and features you want are enabled and present. If not, iterate until it does!

wolfSSL FIPS ready is open source and dual-licensed. More information about building FIPS ready can be found in the FIPS Ready user guide.
More information about wolfSSL and curl can be found on the curl product page.
Details on wolfSSL support for curl is also located on the support page.

Additional OpenSSL Compatibility API

With each release of the wolfSSL embedded SSL/TLS library, new improvements and feature additions are always included. The wolfSSL team has made sure to improve and update support for various open source projects. This holiday release of wolfSSL 4.3.0, we are happy to include expansions in our OpenSSL Compatibility layer. As many people know, the OpenSSL project is struggling with FIPS, and their new FIPS release is not expected until December 2020. The version of OpenSSL that supports FIPS goes into End Of Life and is no longer supported in December of 2019. As a result we are constantly expanding the OpenSSL compatibility API to help people migrate from OpenSSL to wolfSSL. In this release the API wolfSSL_CertManagerGetCerts() and wolfSSL_X509_STORE_GetCerts() were added for retrieving certificates.

Additionally, should you be using one of the OpenSSL derivatives like BoringSSL, we can also support you.

wolfSSL + Nginx

The wolfSSL embedded SSL/TLS library provides support for various open source projects, including Nginx. For those who are unfamiliar, Nginx is a high-performance, high-concurrency web server. Like wolfSSL, it is also compact, fast, and highly scalable. Additionally, wolfSSL also provides support for TLS 1.3 and features such as OCSP, so Nginx servers can be configured with the latest and most secure protocols.

Nginx and wolfSSL make a likely pairing because they are both lean, compact, fast, and scale well under high volumes of connections. wolfSSL + Nginx is available in a public GitHub repository.  The configure option --enable-nginx will compile the wolfSSL libraries with Nginx support.

wolfSSL also provides FIPS and FIPS ready versions of the wolfCrypt library, meaning Nginx can be built FIPS compliant. More information on wolfCrypt FIPS can be found on the wolfCrypt FIPS FAQ page.

For more information on wolfSSL + Nginx, TLS 1.3, OCSP, FIPS, or for any additional questions, contact facts@wolfssl.com.

Added new support for MQX v5

With each release of the wolfSSL embedded SSL/TLS library, new improvements and feature additions are always included. The wolfSSL team has made sure to incrementally improve and update support for our various partners. In our wolfSSL 4.3.0 holiday release, we are happy to bring improved support for MQX. wolfSSL has added new FREESCALE_MQX_5_0 macro for MQX v5 support!

For those who are unaware MQX v5 is a continuation of the MQX Classic product available under low-cost commercial licensing terms. MQX v4.2 is no longer available and has been superseded by v5. MQX v5 is backward compatible with MQX Classic and includes a multitasking RTOS kernel, a TCP/IP stack (RTCS) with Internet protocol v6 (IPv6), embedded MS-DOS file system (MFS), USB host/device stack and task-aware debugging. MQX v5 board support packages (BSPs) are available for a number of platforms, with other BSPs available upon request.

wolfSSL MQTT Sensor Network (MQTT-SN)

The MQTT Sensor Network standard provides a lightweight networking protocol perfectly suited for low cost, low power hardware. The protocol allows using small topic identifiers in place of the full topic name when sending and receiving publish data.

The wolfMQTT SN Client implementation is based on the OASIS MQTT-SN v1.2 specification. The SN API is configured with the –enable-sn option. There is a separate API for the sensor network API, which all begin with the “SN_” prefix. The wolfMQTT SN Client operates over UDP, which is distinct from the wolfMQTT clients that use TCP. The following features are supported by the wolfMQTT SN Client:

  • Register
  • Will topic and message set up
  • Will topic and message update
  • All QoS levels
  • Variable-sized packet length field

You can download the latest release of wolfMQTT from our website or clone the repository from GitHub.
