Have you heard talk about SSL 3.0, TLS 1.0, TLS 1.1, TLS 1.2, and TLS 1.3 but never really knew the differences between the different versions? Secure Socket Layer (SSL) and Transport Security Layer (TLS) are both cryptographic protocols which provide secure communication over networks. These different versions are all in widespread use today in […]

Did you know that wolfSSL supports running on the RIM PlayBook? The PlayBook runs the QNX operating system, which we have supported for the last five years – ever since our first source release of wolfSSL. We have posted before about wolfSSL`s build sizes on QNX, which are an impressive 80k (compared to a standard […]

See Jack Ganssle’s discussion on the report here:  https://www.embedded.com/electronics-blogs/break-points/4208881/2010-VDC-survey-of-embedded-software.  A couple items stand out for us, as a company providing open source embedded ssl:  1. 46% of embedded developers are using a TCP/IP stack.  What we’d like to know is the subset of those developers using SSL.  If embedded ssl usage maps to general ssl […]

Hi! Our Java-based SSL provider has been in alpha for two months now, and we’re actively preparing a beta release. Please contact us at info@yassl.com if you have identified bugs, want to request a feature, or think you’ve spotted potential optimizations. Thanks!Team yaSSL

Do you have a need to analyze SSL traffic? Beginning with the wolfSSL 1.5.0 release, we have provided a build option allowing the wolfSSL embedded SSL library to be built with SSL Sniffer functionality. This means that you can collect SSL traffic packets and with the correct key file, are able to decrypt them as […]

wolfSSL embedded ssl has been available for QNX since the first source release of the product.  We have compared wolfSSL’s current build size on QNX against OpenSSL and the results surprised us.  A standard wolfSSL build for QNX is 80k.  This compares to a standard OpenSSL build size of 2M.  The wolfSSL embedded implementation is […]

wolfSSL is a popular tool for digitally signing applications, libraries or files prior to loading them on embedded devices. As such, it is ideal for signing firmware updates. The reason that embedded RTOS environments do not include digital signature functionality is because it has historically not been a requirement for most embedded applications.  However, in […]

Hi!  Most of our readers will already know that AES is a key encryption standard used by governments worldwide, and that wolfSSL has always supported AES.  Intel has released a new set of instructions that is a faster way to implement AES, and wolfSSL is currently the first ssl library to fully support the new instruction […]

Release 1.6.5 for CyaSSL adds bug fixes and x509 v3 self signed certificate generation.  For general build instructions see doc/Building_CyaSSL.pdf.  For details on how to use certificate generation, refer to section 11 in the wolfSSL manual. To enable certificate generation support, add this option to ./configure ./configure –enable-certgen An example is included in ctaocrypt/test/test.c and documentation […]

Here’s a nice article for embedded designers faced with securing an 802.11 device:  https://www.embedded.com/design/prototyping-and-development/4206409/10-things-to-consider-when-securing-an-embedded-802-11-Wi-Fi-device. Stapko’s item 8 on the list caught our attention.  He correctly states that “Wi-Fi security protocols are big and slow.”  However, the article is an overview, and is not intended to discuss which ones are bigger and slower, and which ones are […]
