In our ongoing quest to bring the power and capabilities of wolfSSL products to all Espressif ESP32 developers, we are proud to announce two new upcoming Managed Components in the ESP Registry: wolfMQTT and wolfSSH. Earlier this year we announced the core wolfSSL availability on the Managed Component Registry. Having wolfSSL as a Managed Component […]

Using wolfBoot as PKCS#11 secure supervisor Today, we’re introducing an exciting feature from wolfBoot that makes use of TrustZone-M technology to enhance safe and monitored access to cryptographic operations. By exposing a complete set of standard cryptographic APIs to the application, wolfBoot provides controlled access to the wolfCrypt crypto engine running in the secure domain. […]

At wolfSSL, we always try to get you the best results possible. Most of the time the best way to achieve this is to use assembly optimization. Unfortunately dedicated assembly tuning is targeted and time consuming so it is not always available for your platform. But there are still many ways to squeeze performance out […]

Have you heard about secure UDP packets? Yes, you can enjoy the security of TLS1.3 level encryption but use UDP instead of TCP on the ESP32. It’s called DTLS. The UDP packets are typically used in lossy, unreliable networks such as LoRa (low-power, long-range radio networks). Most people interested in secure UDP are using the […]

We are constantly enhancing wolfCLU, a command line utility for manipulating certificates. Recently we added some new x509 options. These additions, -req, -extfile, -extensions, -signkey and -* enhance the x509 functionality. Having these options added to wolfCLU helps with generatingself-signed x509 certificates when using the x509 command. [-req] Users can generate a certificate signing request […]

After a long and arduous journey, NIST has finally released the draft standards for 3 post-quantum algorithms: https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.203.ipd.pdf https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.204.ipd.pdf https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.205.ipd.pdf Let’s talk a little bit about each of the documents one by one. FIPS-203 specifies ML-KEM which was based on the NIST Post-Quantum Competition’s only KEM winner Kyber. ML-KEM stands for Module Lattice-based Key Encapsulation […]
