With the holiday release of wolfSSL 4.3.0, we have continued to optimize wolfSSL’s math library performance by expanding our single precision math operations. This greatly speeds up some set key sizes with RSA, ECC, and DH operations. In this release support for 4096-bit RSA/DH operations was added!

With each release of the wolfSSL embedded SSL/TLS library, new improvements and feature additions are always included. In the new release of wolfSSL 4.3.0, we are happy to have improved hardware cryptography support including a Poly1305 AVX2 assembly optimization fix for carry with large input values.

ChaCha20-Poly1305 is a relatively new authenticated encryption algorithm. It was designed as an alternative to AES-GCM. The algorithm is simple and fast on CPUs that do not have hardware acceleration for AES and GCM.

Calling all developers of Qt! wolfSSL is continuously adding new features and support for various open source projects. One of the most recent projects wolfSSL has been working on is support for Qt. We are excited to announce wolfSSL support with Qt version 5.12 and 5.13.

The recent wolfSSL integration with Qt provides a lightweight and performance-minded alternative for the Qt Network backend SSL/TLS. The QSslSocket class makes it easy to add encryption to your application. Now, wolfSSL makes it secure!

If you have any questions or run into any issues, contact us at facts@wolfssl.com, or call us at +1 425 245 8247.

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.

In the latest wolfSSL releases, we have added 200+ new API to our OpenSSL compatibility layer. Many of these new API were added for providing support for Apache HTTP Server. We are excited to announce that as of version 4.2.0, wolfSSL now provides support for the Apache web server with the enable option --enable-apachehttpd. This means you can now build Apache with the latest, most robust security provided by the wolfSSL SSL/TLS and wolfCrypt libraries.

From the early days of the wolfSSL library, we have provided example clients and servers with wolfSSL. These examples have showed how easy it is to use wolfSSL in various configurations. We also use them to help test the library. Over the years we’ve added new features available with TLS to our examples, and our examples have grown a little complicated.

Enter the wolfSSL Examples GitHub repository. We tasked some of our interns, with little to no experience with the wolfSSL library, to write some example clients and servers that set up and test various types of connections. They give you a bare-bones simple demonstration on how to set up a client or server using wolfSSL. We also have examples showing off how to use some features of the library like the certificate manager. Check them out!

To help out with customers who want to update the wolfSSL library without needing to change their application, wolfSSL Inc is striving to maintain application binary compatibility with a subset of our API. As of wolfSSL v4.3.0, the following functions will be compatible across all releases of wolfSSL moving forward:

We have added some testing to our already extensive testing plan to verify these functions do not change.

Given that the security landscape is an always changing surface, we want to make sure you are able to upgrade wolfSSL as easily as possible. There will always be some new attack on the protocol or a cipher and keeping wolfSSL up to date in your product is important to us, and for everyone.

The wolfSSL team has made sure to improve and update support for various open source projects. This holiday release wolfSSL 4.3.0, we have updated the support for the open source project WebRTC to branch m79 (https://webrtc.org/). This is a project that allows real time communication (RTC) with IoT, mobile and web browsers. Many additional API where added to the wolfSSL compatibility layer in order to plug wolfSSL into WebRTC instead of BoringSSL.

Notable advantages of choosing to build WebRTC with wolfSSL are evident through wolfSSL’s superior security implementations, including support for FIPS, PKCS#11, hardware encryption, TLSv1.3, and more. Additionally, 24×7 support and consulting services are available to help build your wolfSSL + WebRTC project.

The pull request with the latest updates for WebRTC can be found here:

The holiday release of wolfSSL, version 4.3, is now available! This release has fantastic new features, optimizations, and bug fixes. Some of the exciting new features that were added to the wolfSSL library are summarized below:

• The addition of –enable-libwebsockets option for support of libwebsockets build was added in the release!
• Updated support of NGINX 1.15.0 and in addition to that we added support for NGINX version 1.16.1.
• Updates to RSA-PSS salt lengths. Macro WOLFSSL_PSS_SALT_LEN_DISCOVER allows for discovering the salt length. Passing RSA_PSS_SALT_LEN_DISCOVER value into wc_RsaPSS_Verify_ex attempts to discover salt length and can use larger salt lengths.
• wolfSSL is 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.
• wolfSSL has an optimized math library for single precision operations. Greatly speeds up some set key sizes with RSA, ECC, and DH operations. In this release support for 4096-bit RSA/DH operations was added!
• Last release (v4.2.0) we came out with support for Google WebRTC, in this release we updated that support to branch m79.
• We added new FREESCALE_MQX_5_0 macro for MQX 5.0 support
• Some users that make use of the OpenSSL compatibility layer like to trim down the bloat while keeping certain API’s. In this release the additional build flag of –disable-errorqueue was added so that the extra error queue is disabled with –enable-opensslextra builds.
• And more…. (check out the README from the download for a full list)

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 wolfSSL 4.3.0, we are happy to say we have improved our support for Nginx. wolfSSL has updated support for Nginx 1.15.1 and added support for Nginx 1.16.1.

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.
