Hi!  The CyaSSL Embedded SSL engine, wolfCrypt cryptography library, and the wolfSSL Embedded Web Server now support Freescale`s ColdFire hardware encryption.  Our initial benchmarks show that AES and 3DES cryptography operations are up to 10 times faster when done with ColdFire`s hardware acceleration.  If you would like to use one of our products with ColdFire, […]

Are you just learning about SSL/TLS, or interested in learning how to layer it into an existing application? If so, we include an SSL tutorial in Chapter 11 of our wolfSSL Manual which provides a good introduction to integrating wolfSSL into a typical TCP socket-based application. Our SSL/TLS Tutorial uses base examples found in the […]

Hi!  One of the alternative ciphers we`ve considered implementing in wolfSSL is the Serpent Cipher.  Not only does it have a cool sounding alliterative name, but it is theoretically more secure than Rijndael/AES.  In fact, it was a finalist for AES.  An overview of the Serpent Cipher can be found here:  http://en.wikipedia.org/wiki/Serpent_(cipher). If you think […]

Hi!  It is rare for a cryptography algorithm to make the pages of the popular press, but Dual_EC_DRBG has done just that!  The best article we`ve seen to date is Kim Zetter`s lucid article in Wired: https://www.wired.com/2013/09/nsa-backdoor/. For the record, we have never implemented the Dual_EC_DRBG algorithm, nor gone so far as to set it […]

Do you have a processor and compiler which support Intel’s AES-NI? If so, you can take advantage of the increase in performance provided by AES-NI in CyaSSL and wolfCrypt. wolfSSL has worked with Intel to publish a white paper describing how Intel’s AES-NI can be used with the CyaSSL embedded SSL library. This paper provides […]

Did you know that the CyaSSL lightweight SSL library has support for hardware-based cryptography and random number generation offered by the STM32 processor? Supported cryptographic algorithms include AES (CBC, CTR), DES (ECB, CBC), 3DES, MD5, and SHA1. For details regarding the STM32 crypto and hash processors, please see the STM32F2xx Standard Peripheral Library document (linked […]

Earlier this month, Google announced that a security compromise had been found which affects applications that improperly initialize, or fail to initialize completely, the PRNG (pseudorandom number generator) before using it for key generation, signing, or random number generation. On the Android Developers Blog, Alex Klyubin, Android Security Engineer, stated that “We have now determined […]
