The yaSSL Embedded Web Server for AVR has some optimizations our users might want to hear about:  Assembly code for the AVR and AVR 32 instruction sets in the SSL cryptography. Assembly code for the AVR 32 instruction set speeds up public key operation during the SSL handshake.  Need to use it?  Already using it?  […]

Hi!  If you came to our site because you are considering wolfSSL as an alternative to OpenSSL, this blog post is your cheat sheet that details the differences between the two products: 1. Size:  With a 30-40k build size, wolfSSL is 20 times smaller than OpenSSL.  wolfSSL is a better choice for resource constrained environments.2. Standards […]

Machine-to-machine communication takes place between both wired and wireless systems all around the world every day. As stated here, “M2M uses a device (sensor, meter, etc.) to capture an ‘event` (temperature, inventory level, etc.), which is relayed through a network (wireless, wired or hybrid) to an application (software program), that translates the captured event into […]

Earlier this week we stated our commitment to ARM by explaining our assembly code optimizations on a number of our math intensive cryptography operations. To give you more information, these optimizations are for Public Key operations with the CTaoCrypt fastmath option. This translates to a speed increase when using RSA, Diffie-Hellman, or DSA. If you […]

The yaSSL booth at ARM TechCon is perfectly situated to check out the QNX based/ARM based Corvette on the show floor.  It’s a silver beauty!  See the pictures below. Reminder:  if you’re building a QNX based car computer and need to secure it with small embedded SSL solution, then contact us.  One of the earliest wolfSSL […]

Hi!  As you may know from reading our posts here, Team yaSSL is exhibiting at ARM TechCon this week.  What you may not know is that we’ve been working with ARM’s mbed.org team to facilitate a port of wolfSSL to mbed.  Why?  Because hobbyists need security too!  And it is fun.  Here at ARM TechCon, mbed […]

Hi!  About 20% of our users are using CTaoCrypt to provide standalone cryptographic functionality, and about 80% of our users have not thought about using it that way.  The purpose of this blog post is to inform users on how to use CTaoCrypt as a standalone library:  1. CTaoCrypt is available as a function set […]

“The Register” reported on using SHODAN to pinpoint embedded devices that are not properly secured yesterday.  See http://www.theregister.co.uk/2010/11/02/scada_search_engine_warning/ for details.  In summary, SHODAN can be used to quickly identify internet connected devices with known exploits.  For us, it points to yet another reason why mobile and embedded systems developers should harden their devices with the […]

Hi!  Do you need OCSP (Online Certificate Status Protocol) in wolfSSL?  Let us know.  We’re currently considering it for a feature addition to our next release.  Sometimes OCSP may be necessary to obtain timely information about the revocation status of a certificate.  OCSP solves that problem.  Additional status information is also available under the protocol.  […]

The yaSSL Open Source Embedded Web Server has support for CGI (Common Gateway Interface). Using CGI, a web server can communicate with other types of programs running on the server. Because the yaSSL Embedded Web Server by itself is only able to deal with HTML file, it can “pass off” scripts written in other languages […]
