We’ve integrated wolfSSL with ?C/TCP-IP and can say it is an excellent implementation well designed for embedded systems. In fact, we can say that the integration process drove us to make some great improvements to our product. For example, our next release will not require the standard C library for even greater flexibility when implementing SSL. But more about that later! Here’s the link to the book review:

This is a great article series. The link can be found here: http://www.embeddedinternetdesign.com/228600068;jsessionid=UJUQFSMN5QD15QE1GHRSKH4ATMY32JVN?pgno=1 (as of 26 March 2018 at 9:21am MDT, this link is broken and has no alternative).
We have recently released an SSL programming tutorial which walks through the process of integrating wolfSSL into a simple application. The wolfSSL embedded SSL library is used, along with a simple echoserver and echoclient. The echoserver and echoclient examples have been taken from the popular book titled Unix Network Programming, Volume 1, 3rd Edition by Richard Stevens, Bill Fenner, and Andrew Rudoff.
Some of the topics covered in this SSL coding tutorial include:
– Required libraries
– What headers are needed
– Startup and Shutdown of wolfSSL
– Sending Data over an SSL connection
– Importing and using Certificates
The SSL tutorial can be found here: SSL Tutorial. All of the source code for the examples is available for download and is linked to from the SSL tutorial webpage.

Hi!
The TomatoUSB community has integrated wolfSSL into the TomatoUSB Firmware as of release 53. wolfSSL is being used in non-VPN editions of the firmware to provide SSL support for httdp and dyndns. They have upgraded to TLS 1.0 from SSL v 2/3 which was previously being used.
TomatoUSB is an alternative linux-based firmware for powering Broadcom-based ethernet routers. It is a modification of the famous Tomato firmware. Some of the added enhancements include support for USB port, wireless-N mode support, and support for several newer router models.
We always like to support community projects which use our products. If you have an open source project and are using wolfSSL or one of our other products, let us know and we’ll gladly support you. If you have questions or would like more information, please contact us at info@yassl.com.

yaSSL made dramatic progress this year on a number of fronts, notably in open source community usage, embedded systems adoption, and technology improvements! Here’s what we’ve done this year, with an outline of our plans for the year to come in a blog post to follow:
1. Participated in 4 industry events, including OSCON, Embedded Live, Embedded Systems Computing, and ARM TechCon.
1. We launched a new and improved web site including new product support forums.
3. We’ve made significant incremental improvements to our documentation.
4. New partners! We’ll announce two new resale partners next week!
5. New technology partners: Canonical, Red Hat, Novell, Freescale and Express Logic.
6. Added a new Competitive Upgrade Program for wolfSSL. More details can be found at our Consulting Services page, under “Rip and Replace Competitive Upgrade“
Our long list of technology improvements includes:
1. ThreadX port. wolfSSL now supports building and running on ThreadX “out of the box”.
2. GoAhead Web Server port. wolfSSL now builds and runs with the GoAhead Web Server through the wolfSSL OpenSSL compatibility layer.
3. Sniffer. wolfSSL now has the ability to sniff an SSL session with the server`s private key and decode the application data.
4. Swig. wolfSSL has a swig interface file to allow multiple language access.
5. Python. wolfSSL now has some python bindings for CTaoCrypt.
6. AES-NI. wolfSSL now has AES-NI assembly optimizations for supported Intel hardware “Westmere”.
7. ARM. wolfSSL now has assembly optimizations for fastmath Public Key operations.
8. Mongoose. wolfSSL now builds and runs with the Mongoose Web Server with the wolfSSL OpenSSL compatibility layer.
9. JSSE. wolfSSL can now be a plug-in for system Java SSL Providers on OS X and Linux.
10. Android. wolfSSL is now ported to Android.
11. SHA-512. wolfSSL now supports the SHA-512 hash on systems with support for 64 bit types.
12. RIPEMD-160. wolfSSL now supports RIPEMD-160 as a hashing algorithm.
13. Key generation. wolfSSL now supports key generation.
14. Certificate generation. wolfSSL now supports certificate generation.
15. yaSSL Embedded Web Server. Our “own” web server with wolfSSL for security.
16. Low static memory. wolfSSL went from a default of 48kB static memory per SSL session to 4kB. (alpha)
17. Low dynamic memory. wolfSSL decreased runtime dynamic memory use. (alpha)
18. Porting. Increased the portability/flexibility of using wolfSSL on non-standard build environments with an OS header with defines that control the build.
19. No stdlib. wolfSSL can now be built without any C standard library headers, developers can now use their own “standard” library plug-in. (alpha)
20. Secure memcache. wolfSSL can now be used to secure memcache network communication including client/patient sensitive data/health records from internal and external snoopers locally and in the cloud. (beta)
21. Mbed. wolfSSL can be built and run on the Mbed microcontroller. (alpha)
We’re happy with our progress this year, and look forward to making even more improvements next year! We’ll be going into 2011 with greater resources and plan to move this project and business forward at an even faster rate.

Recently we’ve been working on porting wolfSSL over to mbed (http://mbed.org/). Now that we have things working, we can report some initial results. wolfSSL takes 2.9 kB of RAM (10% of total) and 63 kB of Flash (13%). That includes our test driver code which is about 3 kB.
On our test machine, we ran some benchmarks of CTaoCrypt and compared them to the results of running on the mbed. You can see that the results of running on the mbed were much slower, but not bad for a 96 Mhz processor with very limited memory.
On our desktop machine, for fastmath RSA 1024 bit:
public RSA: 0.06 milliseconds
private RSA: 0.61 milliseconds
On the mbed for fastmath RSA 1024 bit:
public RSA: 10 milliseconds
private RSA: 165 milliseconds
If you would like more information about these tests or our products, please contact info@yassl.com.
