Hi!  Would you be interested in wolfSSL ported into Dropbear? We have been thinking about putting wolfSSL into Dropbear SSH, and would like your feedback.  Contact us at info@yassl.com if you think wolfSSL should be ported into Dropbear.

Many of our users are curious about how the wolfSSL embedded SSL library will perform on a specific hardware device or in a specific environment. Because of the wide variety of different platforms and compilers used today in embedded, enterprise, and cloud-based environments, it is hard for us to give generic performance calculations across the […]

Hi!  Team yaSSL has been considering the addition of the GOST block cipher to our wolfSSL embedded SSL library.  If you are unfamiliar with GOST, there is a great wikipedia article here:  http://en.wikipedia.org/wiki/GOST_(block_cipher).  If you think wolfSSL should include GOST, then let us know.  We appreciate your feedback.  Just contact us at info@yassl.com.

We`ve started implementing Galois/Counter Mode (GCM) into wolfSSL.  Specifically for use with AES and as a cipher suite for embedded SSL.  One of the benefits of GCM is its efficiency and its performance appears to be pretty good as well.  As an authenticated encryption algorithm it provides both integrity and confidentiality.  We expect to see […]

A short time ago, we announced the unveiling of the online Embedded Software Store by ARM and Avnet (previous post). Since that time, there has been some feedback on the site itself and many bugs and errors have been fixed. We wanted to point our readers to the wolfSSL product page on the Embedded Software […]

Version 2.0.2 of the wolfSSL embedded SSL/TLS library has been released and is now available for download! The first final release of wolfSSL 2.0 after three release candidates provides users and customers with additional bug fixes and feature enhancements. Specifically, version 2.0.2 adds: – Bug fixes – CTaoCrypt Runtime library detection settings when directly using […]

We`ve noticed a couple articles lately mentioning printers as potential attack vectors.  One is particularly disturbing in that not only is a network breach possible, as if that`s not bad enough, but cracked firmware could cause a printer to heat up enough to start a fire: http://redtape.msnbc.msn.com/_news/2011/11/29/9076395-exclusive-millions-of-printers-open-to-devastating-hack-attack-researchers-say .   An easy way to prevent attack […]

Ever wondered what forward secrecy is and how it applies to SSL/TLS?  Forward secrecy protects current encryption even in the event of a future crack of a long term private key.  Using ephemeral keying in TLS with DHE or ECDHE yields this protection because the temporary key is unique and never used again.  So even […]

We often get asked how wolfSSL compares to OpenSSL and what advantages it brings to a project if it replaces a current OpenSSL implementation. To give you a short comparison, see the points below. • Size: With a 30-100kB build size and runtime memory usage between 3-36kB, wolfSSL can be up to 20 times smaller […]

yaSSL has recently ported the MIT Kerberos libraries to Android. The Android platform has previously been void of Kerberos support – forcing Android developers who are creating new applications or porting existing projects to either modify existing code or exclude Kerberos functionality from their apps and libraries altogether. yaSSL has taken the first steps in […]
