wolfSSL+ (pronounced plus) is now available. wolfSSL+ includes NTRU public key encryption. NTRU works well in mobile environments because of the reduced bit size needed to provide the same security as other public key systems. NTRU also isn’t vulnerable to quantum attacks. Several new cipher suites utilizing NTRU are available including AES-256, RC4, and HC-128. […]

Here’s a great article from EE Times on smart utility meter design. Two of the big challenges described in the article are ones that we’ve dealt with before with our current users in the utility space. Securing the meter, and getting updates to the device securely. wolfSSL embedded SSL is a critical component for both design […]

Find it here:  https://sdtimes.com/back-issues/.  To quote the SD Times Editors:  “If your organization still maintains the view that open-source software is code written by amateurs, well, it’s time to move on.”  We think that sums it up nicely.  We can sum up our thinking on open source with a simple statement:  Open source is a […]

We believe that in today’s world of connected devices and heightened security concerns, digitally signing the firmware that is loaded onto your embedded or mobile device has become a top priority. One of the reasons that embedded RTOS environments do not include digital signature functionality is because it has historically not been a requirement for […]

With the release of CyaSSL 1.8.0, users are now able to create CA signed x509 v3 certificates. Certificate generation is turned off by default, but may be turned on during the ./configure process with the following option or by defining CYASSL_CERT_GEN in Windows or non-standard environments: –enable-certgen Currently CyaSSL only supports the MD5_WITH_RSA signature algorithm […]

One of the improvements made in wolfSSL 1.8.0 is lower overall memory use through the use of configurable input / output buffer sizes and less dynamic memory use. wolfSSL 1.8.0 uses small static buffers for input and output. They default to 128 bytes and are controlled by the RECORD_SIZE define in cyassl_int.h. If an input […]

With the release of wolfSSL 1.8.0 we have made wolfSSL even more portable with the addition of a C Standard Library Abstraction Layer.  This means that wolfSSL may now be built without parts of the C Standard Library and user-defined functions may be used instead. The C Standard Library consists of a set of sections of […]
