Stay tuned for an MQTT embeddable broker coming soon. We are going to be expanding our wolfMQTT library to include a lightweight, embeddable broker. The wolfMQTT embedded broker will allow for a low cost, low power, MQTT enabled network, all implemented in a C-based library. wolfMQTT secures MQTT communication using the wolfSSL embedded SSL/TLS library […]

wolfSSL is adding support for complete RTCA DO-178C level A certification! wolfSSL will offer DO-178 wolfCrypt as a commercial off -the-shelf (COTS) solution for connected avionics applications. Adherence to DO-178C level A will be supported through the first wolfCrypt COTS DO-178C certification kit release that includes traceable artifacts for the following encryption algorithms: SHA-256 for […]

As many in the FIPS world are aware NIST retired CAVP (Cryptographic Algorithm Validation Protocol) testing on June 30th of 2020, permanently replacing CAVP with ACVP (Automated Cryptographic Validation Protocol), also referred to as ACVTS (Automated Cryptographic Validation Test System). In order to prepare for this transition NIST offered a “demo server” that Vendors like […]

From the early days of the wolfSSL library, we have provided example clients and servers with wolfSSL. These examples have shown 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 […]

We see a continuing adoption of wolfTPM and TPM 2.0 modules in IoT and Edge embedded systems. In addition, there is a new trend of adding wolfTPM to safety-critical systems, such as aerospace and medical products. For many years, there was no TPM 2.0 stack designed for baremetal and RTOS systems and wolfTPM changed this. […]

Some of our users have been wondering if we were doing benchmarks of our SSL/TLS and cryptography performance. Here are the results we have gathered so far: wolfSSL / wolfCrypt Benchmarking.  This page includes several reference benchmarks as well as comparisons of software versus hardware cryptography. If you have any questions or run into any issues, […]

wolfSSL supports the Online Certificate Status Protocol (OCSP) [https://tools.ietf.org/html/rfc2560] as a client and OCSP stapling version 1 [https://tools.ietf.org/html/rfc6066#section-8] and 2 [https://tools.ietf.org/html/rfc6961]. OCSP is a substitute for Certificate Revocation Lists (CRL). CRLs are a list of certificates that shouldn’t be temporarily or permanently trusted. A major setback for CRLs is the time it takes for these […]

Support for wolfSSL has been upstreamed to the master OpenVPN branch in f6dca235ae560597a0763f0c98fcc9130b80ccf4! This means that you will be able to use wolfSSL directly in OpenVPN. wolfSSL is a lightweight and embedded SSL/TLS library that is extensively tested to provide the best security available. Using OpenVPN with wolfSSL, you can take advantage of our hardware […]

FIPS 140-2 requires the use of validated cryptography in the security systems implemented by federal agencies to protect sensitive information. The wolfCrypt Module is a comprehensive suite of FIPS Approved algorithms. All key sizes and modes have been implemented to allow flexibility and efficiency. The National Institute of Standards and Technology (NIST) is sending FIPS […]

The wolfSSL library has added support for the cisco/cjose library in version 4.4.0. cjose implements Javascript Object Signing and Encryption (JOSE) in C/C++. JOSE is a framework that allows parties to exchange transfer claims in a secure way. The cjose library has been ported to work with wolfSSL, the best tested crypto library on the […]
