Many new additions and updates have been introduced in wolfSSL 3.9.6. For IoT and embedded SSL/TLS there was the addition of embOS and uTasker ports, each of these ports allowing for easily building wolfSSL on the respective environments. Updates were also done to STM32 crypto for using AES-GCM and AES-CCM, and updates were made to […]

In the interest of supporting the lightweight cipher suites used in the IoT, wolfSSL has added ECDHE-ECDSA-AES128-CCM. This is an AEAD cipher suite with the perfect forward secrecy that ECDHE provides, using AES128 counter mode to encrypt the data and provide the 16-byte MAC. If there are any new ciphers or cipher suites you would […]

We are pleased to inform that wolfCrypt has a new wrapper! The wolfCrypt Python Wrapper allows use of the wolfCrypt embedded crypto library in a Python project. This will let users take advantage of the low footprint size of wolfCrypt in IoT projects that use the Python language. Check out the wolfCrypt Documentation (https://wolfssl.github.io/wolfcrypt-py) and […]

wolfSSL has added support for embOS in the wolfCrypt embedded cryptography library. We have example projects in the “/IDE/IAR-EWARM/embOS/” directory which include a library to link against, a benchmark, and wolfcrypt_test that are preconfigured for Atmel’s SAMV71 Xplained Ultra when using IAR Embedded Workbench for ARM (EWARM). These examples are set up to build and […]

OpenSSL released a security advisory on May 3rd 2016: https://www.openssl.org/news/secadv/20160503.txt. Some wolfSSL embedded TLS users are probably wondering if similar security fixes are needed in wolfSSL.  The answer to that is no.  Specifically, CVE-2016-2107 and CVE-2016-2108 are OpenSSL implementation bugs.  Since wolfSSL and CyaSSL embedded SSL libraries have a completely different code base from OpenSSL […]
