wolfSSL has made considerable progress in the first half of 2013, including a company name change to wolfSSL,  improvements to the CyaSSL lightweight SSL library, initiation of our FIPS 140-2 certification, and the introduction of our wolfCrypt cryptography library.  Being an open source company, we like to keep our users, customers, and followers up to […]

The wolfSSL lightweight SSL library has supported ECC (Elliptic curve cryptography) since version 2.4.6 in December of 2012. Currently wolfSSL supports the most common ECC curve type at each bit strength defined by the standard, including the following. SECP160R1SECP192R1   (also called PRIME192V1)SECP224R1SECP256R1   (also called PRIME256V1)SECP384R1SECP521R1wolfSSL defaults to SECP256R1, as is suggested, and as other SSL […]

We are often asked about how we test wolfSSL.  At this point, we believe we have testing that is quite robust, but we acknowledge that there is no such thing as perfect testing.  With that knowledge in mind, we have the goal of incrementally improving and automating our testing rigs over time.  Our overriding goal […]

Many of our customers use the wolfSSL lightweight SSL/TLS package in M2M applications where usage is charged based on data transfer.  As such, it becomes important to minimize data transfer rates when running SSL.  Here are a few thoughts on how wolfSSL M2M users can minimize data packet overhead when implementing our embedded SSL: 1) […]

Did you like the addition of SNI in the last wolfSSL release? If so, you probably will like the Maximum Fragment Length extension as well! TLS specifies a fixed maximum plaintext fragment length of 2^14 bytes. It may be desirable for constrained clients to negotiate a smaller maximum fragment length due to memory or bandwidth […]

We would like to announce to our community that Gearman, a framework designed to distribute tasks to multiple machines or processes, now has SSL/TLS support using the wolfSSL lightweight SSL library. From the Gearman site, Gearman “allows you to do work in parallel, to load balance processing, and to call functions between languages. It can […]

The bi-monthly release of wolfSSL, 2.7.0, is now ready to download from our website.  New features include: – SNI (Server Name Indication) for both the client and server with –enable-sni– KEIL MDK-ARM project files in IDE/MDK-ARM– Domain name match checks now included wildcard and Subject altname checks by default– More consistent error returns across all […]

We receive a lot of questions about the origins of the CyaSSL lightweight SSL library and wolfCrypt software packages.  We get asked where they were developed, and by who?  These questions usually come from US government agencies and their contractors.  Simply stated, mes amis, CyaSSL and wolfCrypt were Born in the USA and written by US citizens. If […]

The wolfSSL lightweight SSL package is used by a healthy chunk of Keil users.  In the interest of better enabling our Keil MDK-ARM users, we`ve added MDK-ARM 4 support and documented it here:  http://www.yassl.com/yaSSL/cyassl-keil-mdk-arm.html. What`s next?  MDK-ARM 5 support.  MDK-ARM 5 will make setup and integration even easier!  Let us know if you are interested […]

Up to now, wolfCrypt cryptography library users have had to use it as a part of wolfSSL.  We are now embarking on the project to separate the two, and when finished should have a separate wolfCrypt download for our users that only need to use our crypto.  Our goals are to make the separate downloads […]
