TLS 1.3 has some significant changes from TLS 1.2 that are targeted at performance. This is the fourth part of six blogs discussing the performance differences observed between TLS 1.2 and TLS 1.3 in wolfSSL and how to make the most of them in your applications. This blog discusses the server generating a key pair […]

TLS 1.3 Performance Analysis – Pre-Shared Key (PSK)
TLS 1.3 has a different handshake flow when using pre-shared keys and this impacts performance. This is the third part of six blogs discussing the performance differences observed between TLS 1.2 and TLS 1.3 in wolfSSL and how to make the most of them in your applications. This blog discusses how and why PSK handshakes […]
Read MoreMore TagDifferences between TLS 1.2 and TLS 1.3 (#TLS13)
wolfSSL’s embedded SSL/TLS library has included support for TLS 1.3 since early releases of the TLS 1.3 draft. Since then, wolfSSL has remained up-to-date with the TLS 1.3 specification. In this post, the major upgrades of TLS 1.3 from TLS 1.2 are outlined below: TLS 1.3 This protocol is defined in RFC 8446. TLS 1.3 […]
Read MoreMore TagOpenSSL Compatibility Layer Expansion
Recently, wolfSSL released version 4.0.0 of the wolfSSL embedded SSL/TLS library. This new version includes many new port/feature additions, maintenance updates, and a couple bug fixes. Among those new feature additions includes multiple new API added to wolfSSL’s OpenSSL compatibility layer! The compatibility layer is a series of commonly used and essential API that users […]

Are you a user of Deos? If so, you will be happy to know that wolfSSL recently added support for Deos RTOS and added TLS client/server examples to the wolfSSL embedded SSL/TLS library for Deos! Deos is an embedded RTOS used for safety-critical avionics applications on commercial and military aircraft. Certified to DO-178C DAL A, […]
Read MoreMore TagwolfSSH Port for µC/OS-III
At wolfSSL, we currently have a wolfSSH port to µC/OS-III in the works! µC/OS-III is a highly portable and scalable real-time kernel. Designed for ease of use on a huge number of CPU architectures, these kernels are a key component of the µC/OS real-time operating system. The features of this kernel allow it to pair […]
Read MoreMore TagwolfSSL’s Effective Timing Resistance
In cryptography and encryption, timing can be an unconsidered element of the security for various operations. However, if an encryption library is built without considering timing or the possible attacks that a malicious agent could execute with timing attacks, then that encryption library could be vulnerable to multiple different attacks that have occurred or can […]

wolfSSL is at wolfSSL at NXP Tech Days Minneapolis this year! NXP Technology Days is a deep-dive, technical training program for engineers designing solutions with embedded technology. This one-day event offers hands-on workshops and technical lectures over multiple markets enabling attendees to customize a schedule that is most relevant to their training needs. Where wolfSSL […]
Read MoreMore TagTLS 1.3 Performance Analysis – Resumption
TLS 1.3 is the latest version of the SSL/TLS specification. There are significant changes to messages and the message flow. These changes are targeted at security and performance. The first performance difference to note is a degradation. In TLS 1.2 performing a resumption handshake is very quick. This comes at a security cost though. Each […]
