The wolfSSL embedded SSL/TLS library supports LwIP, the light weight internet protocol implementation, out of the box!  Users should define WOLFSSL_LWIP when compiling wolfSSL, or uncomment the line /* #define WOLFSSL_LWIP */ in wolfssl/wolfcrypt/settings.h to use wolfSSL with LwIP.  This will enable wolfSSL’s LwIP port, which uses LwIP’s BSD socket API.  LwIP users who are using […]

In this blog series, we are giving our users more details about wolfSSL‘s new SP Math All math library. So far, we have introduced SP Math All, and provided comparisons to both wolfSSL’s normal Big Integer library and wolfSSL’s TFM library. And up next, what about OpenSSL? Is the SP Math All better than OpenSSL? […]

Don’t miss this exclusive opportunity, to gain access to the top thought leaders in the digital space, Ellen Boehm, VP of IoT Strategy at Keyfactor, and Chris Conlon, Engineering Manager at wolfSSL. Register for the Q&A now to get your questions answered on how to navigate the fast paced world of IoT, and to gain […]

New year new projects! We are super excited to announce that we are expanding our post-quantum cryptography needs into SSH. At wolfSSL we try to be progressive with our support of new cryptography technology. To prepare for a post-quantum world where quantum computing presents a threat to public key primitives due to their ability to […]

In previous blogs, the old math library implementations were discussed and wolfSSL‘s new SP Math All implementation was introduced. Also a comparison between the Integer and SP Math All implementations was discussed showing the improvements in the new library that make it a compelling replacement. Let’s take a look at how much faster SP Math […]

In our last blog, the multi-precision math implementations in wolfCrypt were discussed with a feature comparison. In this blog we compare the performance of the SP Math All and Integer implementations. The SP Math All library can be compiled with WOLFSSL_SP_SMALL (–enable-sp-math-all=small) to be small in size, with lower performance, to suit embedded applications. The […]

wolfSSL has a new implementation of the multi-precision math library that is an improvement in every way. The code is in sp_int.c and can be turned on with WOLFSSL_SP_MATH_ALL or -–enable-sp-math-all. Previously the choice was between the implementations in integer.c and tfm.c. The small or Integer implementation (–disable-fastmath) was written to be simple, to have […]

Starting with version 4.6, wolfCrypt includes full implementations of the XChaCha stream cipher and the XChaCha20-Poly1305 AEAD. This new AEAD supports messages with 64 bit size and immense 192 bit nonces, removing all practical limitations on size and number of messages within a cryptographic session or context. It is ideal for applications such as VPN […]

The threat of cyber security attacks exist in every industry simply because the need/want of intelligent devices has increased. From the data aspect – we need to address data at rest, data in transit and firmware updates. These three key factors have been wolfSSL’s wheel house for the last 10 years. In the last few […]

Users and customers build the wolfSSL embedded SSL/TLS library in all kinds of build environments, one of those being Cygwin on Windows. To build wolfSSL for Cygwin, here are the current steps to do so. These instructions can also be found in the wolfSSL Manual. Go to https://www.cygwin.com/install.html and download setup-x86_64.exe Run setup-x86_64.exe and install […]
