#ARMTechCon – Do you have an ARM-based Raspberry Pi project and are looking for a lightweight SSL library with a low overhead to save memory for your project? Are you looking for something open source? Look no further than wolfSSL, formerly CyaSSL. You can obtain the source from our wolfSSL GitHub repository. It builds easily using standard tools included on the Pi. You can even obtain Python wrappers via pip. Thank you and happy hacking!

#ARMTechCon – Do you have a need for an SSH server for your ARM based IoT environment? wolfSSH can satisfy that need in any environment that can run wolfSSL. With a light footprint, wolfSSH can give any lightweight platform an SSH server. It can be used to provide a network interface to devices that used to have serial ports. Or could be used to transfer files into and out of an embedded device. Please send us an email if you are interested in wolfSSH for ARM devices!

The wolfSSH library is dual-license open-source GPLv3 and commercial.

#ARMTechCon – @wolfSSL has partnered with @GreenHillsPR who has ported the wolfSSL #embedded TLS library into Integrity RTOS! @GreenHillsPR and @wolfSSL will be exhibiting at #ARMTechCon in Santa Clara, CA. Stop by booth #321 to visit with the wolfSSL Team and discuss any questions!

On the topic of #ARMTechCon, wolfSSL is available as a CMSIS pack! wolfSSL was one of the first libraries available as a MDK5 software pack, which has evolved into CMSIS.

The wolfSSL ARM MDK5 pack supports CMSIS-RTOS by default, providing both the library and example applications. The user can choose to use a different OS as well. Contact us at support@wolfssl.com for more information about using the wolfSSL CMSIS pack today.

Just in time for the #ARMTechCon 2016, wolfSSL is making hardware accelerated crypto easier than ever on STM32 devices. This is being done by integrating wolfCrypt into STM`s Hardware Abstraction Layer (HAL) through CubeMX. wolfSSL support for CubeMX with HAL will remove the need to tediously configure hardware acceleration by hand and instead let STM32CubeMX, a graphical software from STM, handle the setup of these features.

wolfSSL is currently testing compatibility on STM32F439ZIx and a STM32F437IIHx boards, but with more support coming soon. If you are interested in getting early access to these features and seeing how easily you can benefit from hardware acceleration, contact support@wolfssl.com.

#ARMTechCon – wolfSSL now supports Xilinx SoCs and FPGAs. The wolfSSL embedded SSL/TLS library can be used with FPGAs which use the MicroBlaze CPU and/or Zynq and Zynq UltraScale+ SoCs.

#ARMTechCon – NXP has a new LP Trusted Crypto (LTC) core which accelerates RSA/ECC PKI in their Kinetis K8x line.

The LTC hardware accelerator improves:
 * RSA performance by 12-17X
 * ECC performance by 18-23X
 * Ed/Curve25519 performance by 2-3X.

This adds to the existing MMCAU support which accelerates RNG, AES (CBC, CCM, GCM, CTR), DES/3DES, MD5, SHA, SHA256, SHA384/512 and ChaCha20/Poly1305.

The combined LTC/MMCAU hardware acceleration improves performance, reduces power consumption and reduces code size by 40%.

Are you a fan of speed?  How about new, progressive, and secure algorithms?  If so, you’re in luck!  The wolfSSL embedded SSL/TLS library and wolfCrypt cryptography library have support for two high-performance algorithms for key agreement (Curve25519) and digital signatures (Ed25519).

Curve25519 is an elliptic curve which offers 128 bits of security, designed for use with ECDH (Elliptic Curve Diffie-Hellman) key agreement:

https://en.wikipedia.org/wiki/Curve25519
https://cr.yp.to/ecdh.html

Ed25519 is a public key signature algorithm using the Twisted Edwards curve.  It offers very fast signature verification, signing, and key generation while maintaining a high level of security:

https://en.wikipedia.org/wiki/EdDSA
https://ed25519.cr.yp.to/

For instructions on how you can compile wolfSSL with Curve25519 and Ed25519 support, reference the following post: “Memory Optimized Curve25519 and Ed25519”.  And, to hear about how these two algorithms do performance wise, take a look at “Benchmarks of curve25519”.

If you have any question about support for these algorithms in wolfSSL, please let us know at facts@wolfssl.com.

The embedded SSL/TLS library wolfSSL, has support for ARMv8. Significant gains are seen when using the crypto hardware acceleration. wolfSSL is more than 10 times faster with AES and SHA256 operations on a HiKey (LeMaker version) board when using hardware acceleration vs software!!! If building an IoT project requiring fast, secure crypto/TLS with a small memory footprint size, contact wolfSSL at the email address wolfssl@info.com. Come stop by the wolfSSL booth at ARM TechCon!
