wolfSSL, a TLS library for embedded devices, not only handles the TLS protocol, but also supports bundle file handling functions specified by PKCS#7 (bundle file encoding, decoding, content extraction, signature verification). wolfSSL continues to extend this PKCS#7 handling functionality. wolfSSL is currently extending our wc_PKCS7_VerifySignedData() API to handle PKCS#7 bundle data with multipart and indefinite […]

wolfSSL release 5.6.4 includes support for Kerberos 5 1.21.1. Kerberos is a network authentication protocol using modern cryptography to secure communications. The cryptography in the protocol is strong enough so that a client can prove its identity to a server (and vice versa) across an insecure network connection. You can improve the security of Kerberos […]

Join us for the highly anticipated FIPS 140-3 webinar! Save the date for our insightful session, ‘FIPS 140-3 OE Additions and Planning for 2024 and Beyond,’ led by wolfSSL’s Senior Software Engineer, Kaleb, scheduled for December 7th at 10 am PT. wolfSSL, a leader in embedded FIPS certificates, is on the verge of certifying wolfCrypt […]

In wolfSSL release 5.6.4, we have updated support for Nginx versions 1.24.0 and 1.25.0. Nginx is a high-performance, high-concurrency web server which is compact, fast, and highly scalable. This makes wolfSSL a good choice for the TLS backend. wolfSSL is an embedded SSL/TLS library which supports a wide range of architectures and operating systems. The […]

The wolfSSL implementation of DTLS 1.3 supports Early Data or 0-RTT Data. Early Data is application data that can be sent by the client with the very first ClientHello message. It is also called 0-RTT Data because it requires 0 Round Trip Time before application data can be sent. To utilize Early Data in DTLS […]

We at wolfSSL are continuously improving performance of the wolfCrypt code. Recently we took a look at our AES-GCM on Aarch64 and thought: we can do better. By using the cryptographic instructions built into Aarch64 chips we had already gotten a significant boost over straight C but we saw that we could do more. By […]

wolfEntropy, a software-based entropy source developed by the wolfSSL team, leverages timing jitter variations in memory accesses across various cache levels to generate entropy. It has been available since wolfSSL v5.5.4, and support for Windows has been introduced. This eliminates the need for hardware redesign to incorporate a hardware-based entropy source. The first general purpose […]

Join us on an informative webinar about wolfSSL and Automotive Hardware Security Modules (HSMs) presented by wolfSSL Software Engineer, Bill, on November 30th at 10 am PT. In today’s automotive landscape, vehicles have transformed into sophisticated digital systems, making automotive cybersecurity a paramount concern. During this webinar, Bill will delve into the world of HSMs […]

As many people know, Chinese government regulators are now mandating use of SM2, SM3 and SM4 in critical systems, including automobiles, avionics, power systems, and communication systems. Since many of our customers are multi-nationals that do business in China, they have been requesting the addition of these algorithms in wolfSSL products. Today we are about […]

In WolfSSL release v5.6.4 we have added support for Silicon Labs’ Simplicity Studio. In addition we have tested with the ERF32xG21 series of chips and have created an example setup. More information can be found in the WolfSSL repo. Using our benchmarking tool, we have the following results from a Cortex M33 at 80MHz: wolfCrypt […]
