We have exciting news, wolfSSL will be attending Black Hat Asia! This event will be held virtually in the Singapore Time Zone from September 29-October 2. During this week, information security experts will teach interactive, online Trainings, innovative research will be presented at Briefings, the latest open-source tools will be showcased at Arsenal, and the Business Hall will feature top-tier security solutions and service providers, plus ample networking events and opportunities.
As part of this event, you can attend training sessions that provide opportunities for firsthand technical skill-building taught by specialists for offensive and defensive hackers of all levels and learn the latest information security risks and trends! The virtual Business Hall offers unique opportunities for community engagement between vendors and attendees from around the world including wolfSSL! Come talk to one of our experts on TLS 1.3, embedded security, embedded SSL/TLS, Secure Boot, MQTT, SSH, TPM 2.0, curl + tiny-curl, FIPS, DO-178, MISRA and more. We’ve got the best-tested crypto on the market and the best security without sacrificing performance, so feel free to ask about our benchmarks!
We can’t wait to “see” you!

Did you know that wolfSSL includes a port to the Tenasys INTime RTOS? You can read more in our original press release from Tenasys here: Secured INtime system traffic! Tenasys is using wolfSSL to secure their networked real-time systems and wolfSSL is happy to be integrated into the INTime networking stack which allows us to provide world renowned security to INTime SDK consumers.
wolfSSL also provides a FIPS 140-2 (and soon to be FIPS 140-3!) validated version of wolfCrypt! We also provide a “FIPS Ready” version of wolfSSL which is not associated with a FIPS validation, but includes FIPS-specific code. For users who may need a FIPS validated cryptography library in the future, FIPS Ready can be a good choice to make the transition as easy as possible.

A big thank you to @eli.hughes who has shared results for their own project in hopes of further helping fellow users when building on an embedded Cortex M platform.
“I had a working project build with Segger Embedded Studio for a Nordic NRF52840 (64MHz Cortex M). We switched our build tooling to use cmake/ninja along with the newlib-nano libraries packaged with ARM GCC tools. One thing I noticed is that our TLS handshake in our application went from 3 seconds to about 16 seconds.
Using the built in wolf test functions, I was able to track down the issue.
While Segger Embedded Studio uses GCC, they have their own builds of the C standard libraries.The wolfcrypt ECC routines are very sensitive to how the C libraries are built.
I could eventually get “better” performance than the SES custom library but had to use NewLib and not NewLib-nano. This results in a larger binary but the performance is much better.
wolf Test Time
Segger Embedded Studio w/ custom std libs: 208 seconds
ARM GCC Embedded w/ Newlib-Nano: 608 seconds
ARM GCC Embedded w/ Newlib: 202 seconds
ARM GCC Embedded w/ Newlib &WOLFSSL_SP_ARM_CORTEX_M_ASM : 175 seconds
In addition to using Newlib, I found the macro WOLFSSL_SP_ARM_CORTEX_M_ASM helped quite a bit. (Appears it has hand tuned ASM routines for SP math).
Apparently, newlib is built with speed optimizations and newlib-nano is built with size optimizations. I was surprised at the stark difference. I have other math heavy routines and the difference in execution speed is only 5% between -03 and -Os. It seems that the ECC SP routines have some sensitivity to the C library.
Hope this is helpful to anyone building for a Cortex M MCU.”

Thank you @eli.hughes for sharing these findings. We hope others on the Cortex M will see this. The SP WOLFSSL_SP_ARM_CORTEX_M_ASM option is quite impressive for RSA/DH/ECC math speedups because it uses hand written assembly. At wolfSSL, we love to hear your findings and projects, so please feel free to reach out and keep us posted!

This post has been cross posted from Daniel Stenberg’s blog – originally posted here.
We have started the work on extending wolfSSL to provide the necessary API calls to power QUIC and HTTP/3 implementations!
Small, fast and FIPS
The TLS library known as wolfSSL is already very often a top choice when users are looking for a small and yet very fast TLS stack that supports all the latest protocol features; including TLS 1.3 support – open source with commercial support available.
As manufacturers of IoT devices and other systems with memory, CPU and footprint constraints are looking forward to following the Internet development and switching over to upcoming QUIC and HTTP/3 protocols, wolfSSL is here to help users take that step.
A QUIC reminder
In case you have forgot, here’s a schematic view of HTTPS stacks, old vs new. On the right side you can see HTTP/3, QUIC and the little TLS 1.3 box there within QUIC.
There are no plans to write a full QUIC stack. There are already plenty of those. We’re talking about adjustments and extensions of the existing TLS library API set to make sure wolfSSL can be used as the TLS component in a QUIC stack.
One of the leading QUIC stacks and so far the only one I know of that does this, ngtcp2 is written to be TLS library agnostic and allows different TLS libraries to be plugged in as different backends. I believe it makes perfect sense to make such a plugin for wolfSSL to be a sensible step as soon as there’s code to try out.
A neat effect of that, would be that once wolfSSL works as a backend to ngtcp2, it should be possible to do full-fledged HTTP/3 transfers using curl powered by ngtcp2+wolfSSL. Contact us with other ideas for QUIC stacks you would like us to test wolfSSL with!
We expect wolfSSL to be the first FIPS-based implementation to add support for QUIC. I hear this is valuable to a number of users.
This work begins now and this is just a blog post of our intentions. We and I will of course love to get your feedback on this and whatever else that is related. We’re also interested to get in touch with people and companies who want to be early testers of our implementation. You know where to find us!
I can promise you that the more interest we can sense to exist for this effort, the sooner we will see the first code to test out.
It seems likely that we’re not going to support any older TLS drafts for QUIC than draft-29.
wolfSSL offers commercial support packages and consulting for cURL and tiny-curl! Contact us at firstname.lastname@example.org to learn more.
